Abstract: The position that the deductive-inductive distinction is primarily a distinction between types of support is defended against objections. Allowance is made for additional types of support, notably from relevant but not conclusive considerations.

Abstract: PURPOSE:To shorten change time and reduce excess of depth by a method wherein the feedback gain of a depth deviation signal by a bow rudder, a stern rudder is made variable according to the deviation of a depth and, further, a limiter is added according to the allowance of an attitude angle while the depth is changed. CONSTITUTION:A bow rudder conducts parallel control, differential control, integral control on a depth deviation DELTAH only, while a stern rudder conducts parallel control, differential control, integral control on an attitude angle deviation DELTAtheta and uses a nonlinear control signal on a depth deviation. Therefore, when the depth deviation is small the feed-back gain is the same as a conventional but when the depth deviation DELTAH is great the feed-back gain of the depth deviation to the stern rudder becomes great. Furthermore, in this feedback signal is provided a limiter corresponding to the hull characteristics and the attitude angle allowance when depth is changed exceedingly. Therefore, depth change is carried out at a specified attitude angle and seemingly, the depth change is controlled at an allowable attitude angle thetas during exceeding depth change. Therefore, the depth change is conducted quickly and excess of depth change is reduced.

Abstract: Engine performance can be calculated at a multitude of different levels. It may be assessed at the very elementary level introduced in section 1.1, or it may make allowance for component inefficiences, pressure losses, non-ideal behaviour of gases and numerous other effects. All these affect the performance at the design point; that is, the normal operating condition of a plant or the cruise condition of an aircraft engine.

Abstract: PURPOSE:To adjust the deviation of thickness in a short time when the thickness deviation of the product film already drawn in lateral direction is beyond allowance by modifying the thickness of the profile before being drawn laterally. CONSTITUTION:Thickness in the direction of width of sheet 7 which is not drawn laterally yet is measured by thickness measurement device 19, and the result is inputted to an operational control device 17 where the thickness deviation against the fixed profile is calculated by each die operating bolt 3. The result is sent to an automatic bolt adjusting device 2 and the bolt 3 is rotated to adjust output and modify thickness deviation. By repeating the operation to measure the result by the device 19, the profile of the sheet width direction is fixed within allowance. Then thickness deviation of film 15 already drawn laterally is measured by a thickness measurement device 14 and when beyond allowance the fixed profile of sheet 7 is modified, the bolt adjusting degree corresponding to the modified profile is calculated, and after the bolt 3 is operated according to this calculation, the operation to measure the thickness of film 15 is repeated.

Abstract: PURPOSE:To test surely an element having a certain allowance by giving the output of the element to be tested to an operation circuit through a group of level determinating circuits and by comparing the result of operation with the pattern of expected value. CONSTITUTION:To the operation circuit 7, data corresponding to the uper and lower limit values of allowance of an output value at that time are given from a pattern generator 1 in relation to an input value. Moreover, to the operation circuit 7 is also given an output obtained when an input is given to the element 2 to be tested, through the group 6 of the level determining circuits. The operation circuit 7 performs an operation to determine whether the element 2 to be tested is within the allowance or not, and the result of the operation is compared with the pattern of the expected value by a comparator 3, whereby the accord or discord thereof with the other is detected.

Abstract: PURPOSE:To obtain a stable machining accuracy by a method wherein a sintered ceramic body is ground by rough machining, and then, the finish grinding allowance is ground by using an NC grinder CONSTITUTION:A sintered ceramic body is ground by using an NC grinder equipped with a cylindrical diamond-bonded grinding wheel 6 so that a finish grinding allowance of 01-03mm is left Then, in the finish grinding thereof, the curved surface parts A, B and C of a turbine rotor 1 made of sintered ceramic body are continuously ground along the arrow by means of one leaf of cylindrical diamond- bonded grinding wheel 7 mounted on an NC grinder Accordingly, the sintered ceramic body can be machined with a high grinding accuracy

Abstract: PURPOSE: To strictly set a bearing clearance, in finish grinding work of a small diameter end face and cone back face rib face of a tapered roller bearing inner ring, by previously measuring dimensions of a groove and height of a cone back face rib, calculating finishing allowance of the cone back face rib face on the basis of the above measured values and controlling cutting work. CONSTITUTION: A bearing inner ring 30 is attracted to a backing plate 31, then cone back face rib dimensions and rolling groove diameter of the inner ring 30 are measured by the first and second measuring units 42 and 43. Finishing allowance of a cone back face rib surface 30c is calculated from these measured values. When the finishing allowance is smaller than a lower limit of a preset finishing allowance, a material of this inner ring 30 is rejected to an off-line as an NG part, also when larger than the lower limit and larger than an upper limit of the preset finishing allowance, the material is rejected as an NG part. When the finishing allowance is calculated within a prescribed value, the cone back face rib surface 30c of the inner ring 30 and small diameter end face 30a are simultaneously ground by grinding wheels 32 and 34 till the finishing allowance becomes zero.

Abstract: PURPOSE:To increase the reliability for the monitor of the plant operation, by subtracting the conversion value having a large deviation from the mean value of the measured plant data to obtain the mean value from the rest conversion value and furthermore obtaining the reference value of each plant value from the mean value of the conversion value. CONSTITUTION:The plant data 1 to be monitored is supplied to the converting part 2 to be converted into a state amount. According to the value obtained at the part 2, the allowance range deciding part 3 of the state amount obtaines the mean value of the conversion value and then adds the allowance range to the mean value. The state amount comparing part 4 compares the state amount of the part 2 with the allowance range decided at the part 3, and delivers only the state amount within the allowance range to the mean value calculating part 5 of the state amount. Thus the mean value of the state amount within the allowance range is calculated at the part 5. Based on the mean value, the reference value producing part 6 carries out an adverse calculation to the part 2 to obtain the mean value of each data 1. Then the display information forming part 7 standardizes the data 1 based on the reference value and then delivers the standardization signal 8. In this way, the reliability can be increased for the monitor of the plant operation.

Abstract: PURPOSE:To safely and effectively actuate the regenerative braking by a method wherein a commutation allowance angle of a thyristor circuit is detected, and if if the allowance angle approaches to such a value as causes a commutation failure, a control phase angle is controlled to make the commutation allowance angle larger. CONSTITUTION:Since the commutation allowance angle delta0 detected by a detection device 15 is larger than a reference signal 18 in the range of a large control phase angle gamma, a comparison device 21 feeds no signal 22. If the signal 22 is fed as an output when the control phase angle is reduced and the commutation allowance angle delta0 becomes smaller than the reference signal 18, a control input of a magnetic phase shifter 23 becomes a difference between the signals 20 and 22, a magnetic phase shifter output 24 tends to take the control phase angle gamma large and the commutation allowance angle deltao increases to act so as to prevent the commutation failure from being caused before it decreases below a critical value.

Abstract: 1. The method proposed by R. Bellman for solving the problem of choosing optimum layouts by means of dynamic programming has certain drawbacks due to the incomplete analysis of the possible layout directions. 2. In this article the authors describe a method of “retrogressive corrections” which is a modification of dynamic programming and permits an improvement in the quality of machine layout plotting. 3. Practical calculations have shown that the proposed method is effective, especially (in comparison with the wave algorithm) if the transport networks are optimized with allowance for the local relief and the introduction of additional vertices.

Abstract: Models for determining teller requirements in Bank Branches are investigated to establish policies for managing and operating these branches. In one model, the method used is based upon analysis of congestion in a closed queueing network involving the various activities required by the tellers in carrying out the processing of customers under peak customer demand conditions. Steady-state relationships for the various system state probabilities are obtained in parametric form and can be applied to alternative equipment set-up, service time parameters, and transaction routing schemes to obtain minimum cost policies for operating such systems. In the second model dealing with off-peak customer flows, interest is focused on determining an idleness allowance for tellers, to account for times when no customers are present.
