Patent JP-H01103733-A (JP)
Title: Analog input circuit
Inventor: NISHIDA TAKASHI
IPC: H02P7/288
Filed: 1987-10-16
Abstract: PURPOSE:To suppress the load on the processing of a computer even when the frequency of a PWM signal is high, by providing a counter whose counted result can be given to the computer asynchronously. CONSTITUTION:An analog signal 81 indicating the armature current of a DC motor 70 is compared with a triangular wave signal 121 in a PWM circuit 10 by subtraction and is converted to a PWM signal B by pulse width modulation. A PWM signal 21 having the same waveform is outputted from an insulating circuit 20, and reference clocks are counted by a counter 40 while this signal 21 is active. Clocks are accumulatively counted without resetting the counted value and the counted value is successively read by a microcomputer 40. The microcomputer 50 performs read of the counted value of the counter 40 and the subtraction to be next processed between the other processings and the level of the analog signal 81 is inputted as information to the microcomputer 50.

Title: High frequency power source controller
Inventor: HOSOKAWA TOMIAKI
IPC: H04Q9/14
Filed: 1989-10-06
Abstract: PURPOSE:To eliminate overshoot and damping at the time of the rise of a waveform by inputting an output value set with a power setting circuit to an attenuation circuit through an addition circuit whose amplifier degree is '1' while a delay circuit counts the delay time. CONSTITUTION:After the output of a waveform setting circuit 11 is inputted to the delay circuit 17 and the delay time TD is counted, the output of the circuit rises. While TD is counted, the output value set with the power setting circuit 12 is inputted to the addition circuit 16. Since the amplification factor of the circuit 16 is '1', a set value from the circuit 12 is inputted to the attenuation circuit 13 and a high frequency output rises by open loop control. The input of the inversion terminal of an addition amplifier 24 in the circuit 16 is zero volt since the change over switches 18 and 19 in a switching circuit 14 are turned off. Delay time TD is counted up, the output of the circuit 17 turns on the switches 18 and 19 and a change over switch 20 is turned off. Then, the output of a power detection circuit 8 and the output of the circuit 12 are inputted to both inputs of an error amplifier 23, are compared and feedback control is attained. Thus, the output of the amplifier 23 is inputted to the inversion terminal of an amplifier 24.

Title: Spring return type control motor
Inventor: OIWA SHOJI
IPC: H02K7/10
Filed: 1990-10-03
Abstract: PURPOSE:To suppress the exhaustion of a built-in battery so that a valve can be operated at emergency time by adding an auxiliary motor which is operated by the built-in battery and controls a gear clutch device to a main motor. CONSTITUTION:An auxiliary motor 101 added to a main motor 101 rotates a mobile plate 6 by rotating the gear 1 of a gear clutch device 100 through gears 202 and 102, disengages gears 3 and 4 from each other, and closes a valve, etc., by rotating an output shaft 103 by means of the force of a returning spring 105. While a strong force is required for disengaging the device 100 which is engaged by the pressing force of the spring 105 when the device 100 is disengaged, a short-time rated driving power source is sufficient, since the pressing force becomes negligible after the device 100 is disengaged. Accordingly a large current is made to flow only when the gear clutch device is disengaged by means of an auxiliary motor and, after the device 100 is disengaged, the electric current made to flow is reduced so as to prevent the exhaustion of a battery. Therefore, a small-capacity battery can cope with the disengagement of the gear clutch device.

Title: Method and equipment for measuring distance
Inventor: NISHINO JUN
IPC: G01S17/10
Filed: 1994-10-27
Abstract: PURPOSE: To realize highly accurate measurement regardless of the environment of measurement by calculating the distance to a forward object based on the time difference between the emission timing and the peak forming timing on the waveform of received light and then correcting the distance thus calculated. CONSTITUTION: A time measuring circuit 62 begins the measuring operation based on the output signal (a) from a driving signal generation circuit 11. Upon receiving an output signal (b) from an amplifying circuit 17, a peak detection circuit 61 detects the peak C in a received waveform and delivers a peak detection signal (c) to the circuit 62 thus stopping the time measuring operation. The circuit 62 delivers a measurement of time to a correction circuit 63. The circuit 63 corrects the measurement by subtracting a time error T (min), generated from a small waveform of received light caused by weak reflection of light beam at the time of fog or rain, from a calculated distance and delivers the corrected distance to an operating circuit 41'.  Consequently, highly accurate measurement of distance can be realized based on the difference between the emission timing of a light emitting element 13 and the peak forming timing on the waveform of light received by a light receiving element 16.

Title: Programmable controller
Inventor: TAKASHIMA ATSUSHI
IPC: G05B19/05
Filed: 1985-11-25
Abstract: PURPOSE:To avoid such a case where a main body program is interrupted uselessly by an interruption request by using a means that masks the interruption input designated by an instruction and according to the presence or absence of conclusion of conditions in terms of hardware or releases said mask state. CONSTITUTION:An interruption controller 7 masks the interruption input designated by an instruction and in accordance with the presence or absence of conclusion of conditions for execution of an interruption request permitting instruction in terms of hardware or releases said mask state. In other words, the interruption request permitting instruction is read out of a user program stored in a user program memory 5. Then the interruption input is masked via the controller 7 in terms of hardware as long as the executing conditions of the interruption request permitting instruction is turned off. While the masked interruption input is released via the controller 7 in case the interruption request permitting instruction is decoded in the user program and also the executing conditions of this instruction is turned on. This prevents such a case where the main body program is frequently interrupted due to the generation of an inadvertent interruption request. Thus it is possible to prevent previously the reduction of the executing speed of the main body program.

And said mechanism 20 is constituted to be controlled so that the front and back inversion action of the disk media and the conveyance action can be executed in parallel. Compared with a conventional constitution where the front and back inversion action of disk media and a conveyance action are exclusively executed, the access time of the disk media can be shortened. Besides, the space for inversion actions of the disk media is not independently secured, thereby miniaturizing the device.
