Abstract: A memory management system is structured for use with a self-contained microprocessor to form a multi-user computer. The system operates to establish user and kernel modes each having different operating permissions. When the system is operating in the user mode, certain of the fixed functions of the microprocessor, such as interrupt-off and halt, are blocked from enablement by any user. The system is designed having multiple memory maps, some accessible when in the user mode and all accessible from the kernel mode.

Abstract: A text recorder includes a multi-character display controller which is operated in a multi-character mode to record (e.g., print on paper or generate a CRT or the like display) multi-character sequences in response to operator actuation of a single key of a keyboard substantially identical to a conventional typewriter keyboard. Operator actuation of a key generates a coded signal representative of the actuated key, but in the multi-character mode, the normal text recorder function of printing or displaying the character associated with the key is inhibited, and instead, a memory device is accessed which has stored at a location corresponding to the actuated key, a sequence of coded signals representative of a plurality of characters, functions or both. The storage device may include a plurality of sets of stored signal sequences representing a plurality of multi-character sequences, the selection between the different storage sets being effected based on a particular key or key sequence previously actuated. Particular keys suitable for use in a multi-character mode are keys representing numeric characters, symbol graphics, or various punctuation marks. The invention is applicable to text recorders designed for use with English or foreign languages.

Abstract: For the purpose of connecting a plurality of independent processor units to a single port of a main memory, the processor units are connected in series over individual interface controls, whereby the interfaces are expanded in comparison to the port interface without the interface conditions for the port being changed. The interface controls operate in reciprocal dependency on one another so that the memory access request arising within the processor unit chain becomes effective in individual succession by way of a reciprocal inhibiting without address control, whereby variable connector controls in the interface lines determine the transmission path of both directions between the main memory and the respectively active processor depending upon status signals which, among other things, are influenced by interface signals. Termination of a write operation and clear down of a completed connection occurs by way of an internal interface line of the chain circuit. Given a read operation, the clear down of the connection path to the memory for the request already occurs with the beginning of the read data transmission given completion of the return connection path. For an additional lock mode, two additional internal interface lines are provided in conjunction with a monitoring and inhibit control in each interface control.

Abstract: PURPOSE:To permit a picture infromation storage device to perform two different inputting operations separately either by inputting pieces of picture information, which correspond to retrieval codes inputted together in advance, observing at their codes or by inputting the corresponding retrieval codes after inputting the pieces of picture information. CONSTITUTION:On a keyboard 2, a continuation mode for continuous recording or registration mode is selected and retrieval codes to be registered are inputted successively. Then, a CPU15 receives and stores the input retrieval codes in an RAM16 sucessively. The CPU15 reads the firstly inputted retrieval codes out of the RAM16 to display them on a display device 7, and an operator sets an original, which corresponds to the displayed retrieval code, on a two-dimensional scanner 6, which scans on a picture on the original to record the picture information on a tape 23 on a magnetic tape device 9. Similarly, the codes are read out successively to register corresponding pieces of picture information. In the reversed procedure, pieces of picture information of originals are recorded on the magnetic tape and then the pictures are displayed on the display device to store corresponding retrieval codes.

Abstract: : The FEARS program normally takes the problem's descriptive data from the run-stream. This input data is composed of the Geometry and of the Bilinear/Error matrices. Alternatively, this data can be read from a DUMP-file, which has been generated by a previous execution of FEARS. Once the initial data is read, FEARS enters into a command-mode. In the command-mode, the user must input a command (with some parameters) instructing the program about the next step to be taken. This mode allows the user to have complete control over the iteration process, step by step, reflecting the research nature of the program. On the other hand, the ITERATE command allows the iterations to be automatic. Once a STOP command is given, the run will be terminated. Printed output generated by FEARS consists of summary data after each iteration step. The user also has the option to reprint initial input and/or detailed information about the solution process during the iteration. The formats of these printouts are described. In addition, the DUMP command generates a dump-file of the data structure which can be used as input, either for FEARS itself, or for various postprocessors. Chapter 5 gives the computer dependent control statements necessary to run FEARS on the UNIVAC 1100 computer. The program is supplied with a dummy subroutine giving zero values for the bilinear matrices E and D. If these matrices are coordinate dependent, the user must supply the appropriate subroutine replacing the supplied dummy routine. This preparation must be performed prior to the use of FEARS.

Abstract: A system for recording a video signal derived from a solid state image sensing device including a number of picture cells is disclosed. The video signal is read-out of the solid state image sensing device and is recorded on a magnetic tape of a video tape recording device. When a shutter release button is pushed, the magnetic tape is rewound by a given length and then the magnetic tape is traveled forward. During the forward movement of the magnetic tape, the video tape recording device is set into a reproduction mode and the video signal which has been previously recorded is reproduced. As soon as the video signal is not detected from the magnetic tape, the video tape recording device is changed into a record mode and after a given servo lock time, a shutter is opened for a given period. Immediately after the shutter is closed again, the video signal is read-out of the solid state image sensing device and then is recorded on the magnetic tape which is traveled at a given constant speed.

Abstract: PURPOSE:To continue a data process although a trouble occurs in a computer system, thus prevent a loss of data in a switching mode, by installing a storage region that stores the data added with the time of reception given from an input device to the memories in common of both the primary and secondary systems. CONSTITUTION:An input data added with the time of reception given from an input device 1 of a primary system is stored in a shared memory 6 of the primary system; and an input data applied with the time of reception given from an input device 2 of a secondary system is stored in a shared memory 7 of the secondary system.

Abstract: PURPOSE:To reduce the fatigue of an operator as well as to increase productivity of characters, by securing the function of a space key for a bar key when it is operated independently and the function of a shift key for the bar key when it is operated along with the keys of characters, symbols, etc., respectively. CONSTITUTION:A keyboard part 10 includes a key group 11 of characters, symbols, etc. plus a bar key BK. The key BK is located at a position where it is easily operated by the operator's front thumb. A key scan/detection encoding circuit 12 scans each key within the group 11 and applies the code signal of the pressed key to an input A of a simultaneous keying processing circuit 13. An encoder 14 applies the code signal shown by the BK to an input B of the circuit 13 in response to the keying of the BK. The circuit 13 decides whether the key of the group 11 and the BK are hit simultaneously. In the case of the simultaneous hit, the value of the key code applied to the input A is converted into the value of a shift mode to be delivered to a key code bus X. In case a simultaneous hit is not decided, the code of the input A and the space code of the input B are delivered directly to the bus X.
