Title: Range finder
Inventor: OKADA TOKUJI
IPC: G01C3/06
Filed: 1979-06-16
Abstract: PURPOSE: To improve sensitivity and resolution cosiderabry, by using one light emitting element at least and many light receiving elements to discriminate distance from the optical path constituted by the light emitting element and a light receiving element which has detected maximum light quantity.  
     CONSTITUTION: On the optical path between one light emitting element S at least and n-number light receiving elements R, pinhole HS where the irradiation light to the object passes through range finder front P of a distance calculation reference face and pinhole HR where the reflection light from the object passes through front P are provided. Now, if light emitting element S is caused to emit always light to detect the light quantity input to many light receiving elements R by electric scanning, the light quantity becomes maximum in a specific a light receiving element closely connected with existence position of the object. When this specific ligh receiving element is the K-th light receiving element, measured distance D is calculated by expression D=H×L/[W-L+(K-1)×B]. D is expressed by the function of K because H, L, W and B are physical constants peculiar to the range finder, and sensitivity and resolution can be improved considerably by increasing the value of K.

Abstract: PURPOSE:To improve the stability at the time of idling by making a constitution in which the phase of an air intake and exhaust cam is set so as to slide the valve timings only of an air intake valve opening side and an exhaust valve closing side. CONSTITUTION:At a multi valve type internal combustion engine, the phase of an air intake and exhaust cam 20 is set so as to slide the timings only of an air intake valve 12 opening side and an exhaust valve 14 closing side and a constitution is made.

Filed: 1983-05-02
Abstract: PURPOSE:To eliminate the need for replacement of a battery due to deficiency of electromotive force by using the battery charged by an energy supplied from a converter via an optical cable as a power supply for control to use a terminal device even at a failure of commercial power supply. CONSTITUTION:Whether or not a terminal 30 is idle is checked in a prescribed period during the operation of a signal transmission/receiving circuit 11. If the terminal device is idle, a light having a DC component is transmitted to an electrooptic converter 13 via a power feeding circuit 14. This light is transmitted to an optoelectric converter 34 via an optical cable 21 and converted into electric quantity. This DC component is detected by a power feeding detecting circuit 36 and charged into the battery 37. A control power supply for the terminal device 30 is supplied from the battery 37 charged in this way. Since the battery 37 is charged periodically in this way, the replacement of the battery which had been required in conventional systems is not needed. Since the power energy is supplied via the optical cable 21, electric wires used conventionally are not required.

Title: Voltage regulating relay
Inventor: KAWASAKI SHIYOUGO
IPC: H02H7/04
Filed: 1991-04-09
Abstract: PURPOSE:To quickly detect overvoltage under light load and undervoltage under heavy load by varying a set voltage level for detecting secondary undervoltage in response to set value data corresponding to the magnitude of load. CONSTITUTION:A PT 3 and a CT 4 are connected to the demand side of a transformer 2 having output voltage regulated through a voltage regulating relay 1. Outputs from the PT 3 and the CT 4 are fed to the voltage regulating relay 1 in order to detect fluctuation of load. Control means 6 for the voltage regulating relay 1 selects a reference value from set value data previously stored in a memory means 7 according to a load current fed from the CT 4 and a secondary voltage fed from the PT 3 and provides a switching control signal to a tap so that the secondary voltage comes within a predetermined dead band. A detection voltage setting means 8 then increments/decrements the upper and lower limit values corresponding to the load current by 5% to produce a set value voltage and when a comparator/detector 9 detects deviation from a set value, an alarm is produced from an alarm unit 5. Consequently, overvoltage under light load and undervoltage under heavy load can be detected and regulated quickly.

Title: Control circuit
Inventor: SATOU YOSHIO
IPC: H04Q7/18
Filed: 1979-06-18
Abstract: PURPOSE: To exercise stable control by preventing a program from getting out of control while reducing the electric power control of a control circuit, used for a mobile communicating equipment, etc., when the circuit expects to receive a signal, by cutting off electric power supply to the circuit during the period.  
     CONSTITUTION: Once applied with start signal 9, FF10 is set and transistor TR11 conducts to put electric power source 7 to work. At this time, initializing circuit 1 sends an earth signal to CPU2 for a time set by resistance 18 and capacitor 19. Receiving this, CPU2 regards this signal as a reset signal to restart processes with the 1st one. Therefore, a control part, even if malfunctioning due to noises, etc., is released for restart processing, so that stable control will be exercised. Consequently, when a signal is being expected, a control circuit cuts off the electric power supply to reduce the power consumption and also to prevent a program from getting out of control at the same time, so that the stable control can be exercised.
