PROBLEM TO BE SOLVED: To provide a vibration absorbing adjuster capable of being mounted within an equipment size and good in mountability without producing a dead space in equipment. SOLUTION: The vibration absorbing adjuster 1 is provided for supporting equipment installed on a floor surface 40 and absorbing the vibration of the equipment while adjusting the level of the equipment. It includes a vibration absorbing body 2 having a fine adjustment screw hole 12 for level fine adjustment formed in the center of the upper part, for absorbing vibration in contact with the floor surface, a level adjustment part 3 having a joint portion 14 formed on the lower part so as to be threaded to the fine adjustment screw hole 12 and a turning handle 16 formed on the upper part side, and a supporting column 4 attached to the upper part of the level adjustment part 3 for supporting the equipment. The supporting column 4 has a front end 20 formed in a conical or trapezoidal-cone shape at an angle of face-contact with a chamfered portion 33 of a mounting hole 32 formed in a bottom 30 of the equipment.

The invention belongs to the technical field of measuring tools, and particularly relates to a pointer type angle measuring device with the wireless power lighting function. The pointer type angle measuring device is used for measuring the angular dimension state of an object and comprises a shell, a dial, a pointer and an electronic circuit. The electronic circuit comprises a wireless power supply circuit and a wireless power receiving and lighting circuit. The wireless power supply circuit is composed of a microcomputer processor, a wireless transmission circuit, an LED drive circuit, an energy-saving circuit and a power circuit. The wireless power receiving and lighting circuit is composed of a power receiving coil, a capacitor and light-emitting diodes. The shell is composed of a front cover and a rear cover. The pointer is arranged in the inner cavity of the shell and is of a shell structure with an inner cavity, and the head portion of the pointer is made of a transparent material. A circuit board in the wireless power receiving and lighting circuit and the light-emitting diodes for lighting of the head portion of the pointer are arranged in the inner cavity of a pointer body. The pointer type angle measuring device has the advantage that the pointer can emit light, and therefore the pointer type angle measuring device can be conveniently used by people in the environment with weak light.

Pointer type angle measuring device with wireless power lighting function

PURPOSE:To control a crank shaft with high accuracy according to various operations by comparing the rotating angle of the crank shaft detected by a resolver and preset position data and outputting various control signals at good timings CONSTITUTION:The crank shaft 5 is rotated by the operation of a driving device 13 via a clutch 11 and a punch 17 is lifted by a connecting rod 15, by which press working with a die 19 is executed The resolver 21 is provided to the crank shaft 5 at this time and the signal is sent via an input/output part 33 to an angle computing part 29 according to the rotating angle of the crank shaft 5 The computing part computes the rotating angle of the crank shaft 5 and sends the signal thereof to a main control part 25 The position data for executing the timing control of various control members for the rotating angle of the crank shaft 5 is previously set in a digital setting part 27 The main control part 25 compares said position data and the detected rotating angle of the crank shaft 5 and outputs the timing control signal to the various control members via a control signal output part 31 when the crank shaft 5 comes to the prescribed position

Crank shaft controller

PURPOSE:To enable to move in correct accuracy in parallel a driven unit by using a plurality of rotational shafts by synchronizing two motors. CONSTITUTION:When rotational shafts 2, 3 are rotated to move a feed bar 1 by operating motors 4, 5, pulse generators 8, 9 generate pulses. A controller 10 counts pulses by a counter, and when the difference reaches the allowable limit value, the advanced motor is stopped, the other motor follows up the advanced motor, and the stopped motor is again operated. In this manner, the displacement at the both ends of the bar 1 can be limited within the prescribed range, and the motors are moved.

Synchronizer of plural motors

PURPOSE:To enable the detection of stoppage of a crank in a press device with extreme ease in either forward or reverse rotation simultaneously with finding the angle of rotation thereof by lighting light emitting elements sequentially according to output of an encoder CONSTITUTION:The minimum digit output of an absolute encoder 3 is taken out as outputs of devices 0, 2, 5 and 8 with a B/D conversion circuit 4 and a forward-reverse rotation discriminating circuit 7 outputs the L level in the forward rotation and the H level in the reverse rotation to be inputted into an ExOR10 In the forward rotation, as the rotation is done upto 10 deg, a signal of the H level is inputted into the ExORs 10 through a B/D conversion circuit 5 and an OR gate 8 and a light emitting diode 2 corresponding to 10 deg comes ON When the rotation is reversed from the stoppage, all outputs of the ExORs10 move to the L level and the light emitting diode lighted so far goes off while that extinguished so far is lighted With the continuation of the reverse rotation, light emitting diodes 2 continue to light as outputs of the encoder vanishes thereby enabling the informing of the stoppage at the reverse rotation time even when the engine is stopped at any time

Crank angle gauge with forward/reverse rotation discriminating function

PURPOSE:To provide a forward and backward discriminating circuit which knows easily forward and backward revolutions by the output signal from a flip-flop by taking out the specific numerical value of the lowermost digit in the output from an absolute encoder attached to a revolving shaft as an origin signal and providing the flip-flop in association to the forward and backward revolution signals after inputting of the origin signal. CONSTITUTION:If the ''O'' output of the above-described absolute encoder 3 is determined as an origin, the output is inputted to ''O'' of the figure A at every time when a revolving crank goes to ''O'' or below at every 10 deg. to raise the output from a flip-flop 12 to an H level thereby opening gates 14, 15. If the crank revolves forward, ''2'' is first outputted and is inputted through the open gate 14 to the R of a flip-flop 13, the output from which attains an L level. On the other hand, if the crank revolves backward, ''8'' comes after ''O'' and therefore, the output is inputted to the S of the flip-flop 13 conversely from before and therefore the output of a forward and backward discriminating circuit 7 rises to an H level. The flip-flop 12 is reset by inputting ''5'' after any output is emitted as mentioned above. The L level is outputted from the circuit 7 if the crank revolves forward and the H level is outputted therefrom if the crank revolves backward in the above-mentioned way, by which the forward and backward revolutions are discriminated.
