Title: Proximity fuse
Inventor: MIZUSAKI KATSUO
IPC: G01S7/36
Filed: 1987-09-08
Abstract: PURPOSE:To make the use of a radio wave hard to discover on an enemy side, by detecting the reflected signal from a target while mixing the same with a part of the output of an oscillator and performing detection by three correlation detectors and comparing the outputs of the correlation detectors with the output of a bias adding circuit. CONSTITUTION:A modulator 3 modulates the output of a directional coupler 2 on the basis of the signal wherein the output of a code generator 10 is delayed by one bit and an antenna 6 allows the output of a variable attenuator 4 to pass through a circulator 5 to emit the same to the air. The signal transmitted from the antenna 6 is applied to a target to be reflected and again received by the antenna 6 and a mixer 7 allows said signal to pass through the circulator 5 to mix the same with the output of the coupler 2. The output signal of a video amplifier 8 is trisected to be detected by the first, second and third correlation detectors 13a, 13b, 13c while the correlation with the output of the generator 10 and the output of a  T delay circuit 12 obtained by delaying said output is taken. The outputs of the detectors 13a, 13b are compared with the output of a bias adder 14 by the first and second comparators 15a, 15b to be outputted to an ignition circuit 16 or passed through an integrator 17 to control the oscillation frequency of a voltage control oscillator 9.

Title: Voltage comparator
Inventor: IMAIZUMI SHIGEKI
IPC: H03M1/34
Filed: 1990-08-29
Abstract: PURPOSE:To offer a voltage comparator whose operating speed is not reduced even with an input of an input signal at a high through-rate by providing a sample-and-hold capacitance for one input of a differential amplifier and a sample-and-hold capacitance for the other input of the differential amplifier. CONSTITUTION:A hold capacitor C2 and other input of a differential amplifier 1 are separated by a buffer circuit 5 comprising an opened switch SWX, a high input impedance, a low output impedance and high load drive capability for an ON-period of a switch SW2b, that is, a sampling period of an input signal V2 to the hold capacitor C2 during the change. Thus, a high through-rate input signal V2 does not effect the input of the differential amplifier 1 at the sampling of the input signal V2.

Abstract: PROBLEM TO BE SOLVED: To obtain a control apparatus by which the divergence of a q-shaft current and the overexcitation of an induction motor due to the divergence are prevented by a method wherein an apparent resistance value is introduced into the computing operation of a torque-compensation-amount computing unit. SOLUTION: In a torque-compensation-amount computing unit 32, the torque compensation amount of a q-shaft voltage is computed on the basis of the generated torque, of an induction motor 2, which has been found by a torque computing unit 31. In a compensation-amount computing unit 33, a prescribed computing operation is performed by a frequency command value, a q-shaft current, a torque compensation amount, the preset d-shaft current value of the induction motor 2, a primary resistance value, a leakage inductance and an apparent resistance value, and a q-shaft voltage compensation amount and a d-shaft voltage compensation amount are output. Thereby, it is possible to prevent the divergence of the q-shaft current and the overexcitation of the induction motor due to the divergence.  In addition, in the torque-compensation current of the q-shaft voltage due to the apparent resistance value is compensated, and the minimum value of the output voltage of an inverter is ensured by limiting the lower-limit value of various control amounts. As a result, a torque characteristic is improved in the low-speed region of the induction motor.

Title: Task execution control method
Inventor: TAKANO MASATOSHI
IPC: G06F9/52
Filed: 1994-09-21
Abstract: PURPOSE: To prevent a task which is high in priority from being kept waiting for processing. CONSTITUTION: A task τ3 with high priority and a task τ1 with low priority are executed and those τ3 and τ1 have parts (critical session) to be brought under exclusive control since they share a resource.
