Abstract: The present invention relates to a method of defining a hole position of a punch mounting part in a progressive mold. Position of the holes (PH1-PH3) for parts such as bolts which mount punches on a plate (PLT) are defined, the positions of the part holes (PH1-PH3) are stored in correlation with punch shapes (DF1-DF3), and the part hole positions are moved in association with movement of the punch shapes.

Abstract: A fundamental method and apparatus for using wave-type energy, such as light, to provide: amplification, energy control, and logic functions including OR, EXCLUSIVE OR, and INVERTER; as well as: bistable information storage; computing; visual display; and dynamic imaging (where images are modified continually as computation proceeds) is disclosed. The method uses modulated input beams that are able to produce interference fringes, that are separated into constructive interference component regions and destructive interference component regions, to provide outputs from individual functions, that result from the interference which occurs in the separated interference-fringe component regions. Many basic functions are interconnected to produce more complex functions including complete digital and analog computers. Holograms made up of many subholograms are used to separate fringe component regions, and to direct function interconnecting beams.

Abstract: A charge domain vector-matrix product processing system. The system includes a charge coupled device tapped delay line, an array of digital parallel shift register memory devices, and a signal processor. A sampled analog signal is stored within the tapped delay line, and multiple vectors of m-bit words are stored within the digital memory device. The signal processor sucessively applies vectors from the digital memory device and charge packets from the tapped delay line to an array of digital-analog multipliers. The signal processor then sums the outputs of the digital-analog multipliers and produces an output charge packet corresponding to a respective element of the vector-matrix product.

Abstract: An output circuit with a controller and intelligent output stages for process control where the output stages are supplied with power from separate voltage sources which are electrically separated from each other. The actuating commands from the controller for semiconductor switches in the output stages and feedback signals to the controller from the output stages are carried back and forth via optical couplers. Each output stage receives its own direct current supply, which is obtained by rectifying a chopper current supply. The feedback signals are transmitted serially being clocked by pulses derived from the chopper current supply. Thus, actuating commands may be issued without retrospective effect. Switching operations may be carried out during the process. Diagnostic signals concerning the load current circuit can provide feedback efficiently.

Abstract: A compressive receiver (10) includes a modulation circuit (14) that modulates the receiver input signal with compensation values equal to the ratio of the transfer function of an ideal linear dispersive delay line to that of the main compressive-receiver linear dispersive delay line (22). An auxiliary linear dispersive delay line (16) dispersively delays the results modulated signal at the reciprocal of the compressive receiver's chirp rate, and the resultant signal is progressively translated in frequency by a frequency translator (18) at the compressive-receiver chirp rate. As a consequence, each point in a signal-frequency component of the input signal is translated to the frequency at which the compensation function was evaluated in modulating the component at that point in time, so the departure of the main dispersive delay line (22) from linearity is compensated for, and increased dynamic range results.

Abstract: An industrial control system device that can be utilized for drive control, process control and/or logic control and which is comprised of a unique combination of hardware and software. Use of one or more of the devices in an industrial control system application permits the control system to be partitioned into subsystems which communicate with one another and which operate as self-contained units. Each subsystem can be further subdivided into modules that have distinct operating functions. The software utilized by the control system device separates the required operating functions of the control system into distinct tasks that operate concurrently (multi-tasking) on a priority level basis while sharing system data and control signals. Three programming languages (BASIC, Control Block, Ladder Logic) are employed so that the most appropriate language can be utilized for each task.

Optical intensity controlling elements of a panel are placed in optical paths defined by the pairs in the first layer and the pairs which correspond in the second layer to the pairs of the first layer, respectively. When the light emitting element rows are driven, optical beams are emitted by the light emitting elements of the first layer and controlled by the respective controlling elements to have first-layer controlled amounts of light, respectively.

Abstract: A method of controlling an operating speed of the loom for increasing the production rate by varying the present operating speed so as to be increased includes a step of estimating a stop rate at the final point of time during a predetermined period at a certain time during the predetermined period, and comparing the estimated stop rate with a predetermined limit stop rate, and setting the present operating speed to increase it when the estimated stop rate is less than the limit stop rate and to decrease it when the estimated stop rate exceeds the limit stop rate.

Abstract: When machining cams with the same profile data, finished shape errors tend to increase as the diameter of a grinding wheel decreases. In order to keep the finished shape errors within a tolerance, the profile data used for machining must be renewed with new profile data corresponding to the present diameter of the grinding wheel. In the disclosed numerically controlled cam grinding machine, optimum wheel diameters, at which new profile data must be calculated, are decided automatically. The numerical controller calculates the marginal diameters which require renewal of profile data based upon the machining tolerance when a new grinding wheel is attached to the wheel head. After that, the numerical controller calculates new profile data from the marginal wheel diameter and lift data, when the present wheel diameter reaches into one of the marginal wheel diameters. The old profile data is renewed with the newly calculated profile data corresponding to the marginal wheel diameter.

Abstract: Control circuit, which is connected to a data processor, a D-A converter, such as a current integration type adaptive delta demodulator, and a data processing mode change command terminal, attenuates output from the data processor in response to a data processing mode change command from the data processing mode change command terminal while delaying the data processing mode change command by a first prescribed time to supply the command to the D-A converter and releasing the attenuation of the output of the data processor after a lapse of a second prescribed time which is longer than the first prescribed time. Thus, no instable output data from the data processor appear at the output of the D-A converter so that no noise is caused.

In the transformation, the spatial vector of the input signal is applied to the plurality of first conductors.
