Title: Hot water supply device by solar system
Inventor: NISHINO TETSUO
IPC: F24S90/00
Filed: 1981-04-23
Abstract: PURPOSE:To enable supply of hot water of a fixed temperature at low cost through making use of a water boiler as substitute of the device of a heat source by connecting an outlet conduit pipe of a regenerator with an inlet conduit pipe of a domestic use instantaneous gas water boiler and providing a motor operated valve interlocked with a thermoswitch on a connecting conduit pipe. CONSTITUTION:An outlet conduit pipe 7 of a regenerator 4 which exchanges heat of a thermal medium 3' circulating within a closed conduit pipe 3 communicated with a heat collector is connected with an inlet conduit pipe 9 of a home use instantaneous gas water boiler 8a by a connecting pipe 10, on which an electric three-way valve 12 being interlocked with a thermoswitch 11 is provided. Then, a bypass pipe 15 which is branched from valve 12 and is connected with an outlet conduit pipe 14 of the above boiler 8a is provided. With this, a temperature of water 6 within the connecting pipe is detected and the electric three- way valve 12 is caused to be opened or closed with an electric signal as well. When the temperatue of the water 6 within the connecting pipe 10 is low, the water 6 is flowed to a boiler 8a side automatically and on the contrary when it is high, hot water is supplied to valves (a) and (b) through a bypass pipe 5.

Title: Focussing type ultrasonic probe
Inventor: KOGURE SUMIO
IPC: G01N29/22
Filed: 1982-04-16
Abstract: PURPOSE:To obtain a focal point with an optional depth by exchanging only a shoe, by a method wherein an acoustic lens space is provided to the shoe by processing the same and focussed ultrasonic waves are obtained by utilizing the difference in acoustic velocities of the material quality of a substance filling said space and the material quality of the shoe. CONSTITUTION:Incident ultrasonic waves applied to a shoe 3 provided with a recessed part 2 having radius of curvature of R from a vibrator 1 bring lens effect by a medium 4 having acoustic velocity different from that of the shoe 3 filling the recessed part 2 to be converged. In this case, the shoe 3 is brought into close contact with an object 5 to be tested through the medium so as to obtain converged ultrasonic waves at a focal point 6 by the difference in acoustic velocities of the shoe 3 and the object 5 to be tested. By this constitution, because a focal point with an optional depth can be set by exchanging only the shoe with respect to one vibrator, a probe with various focus depths can be supplied inexpensively.

Title: Release lever assembly
Inventor: YONEDA KAZUHIKO
IPC: F16D13/70
Filed: 1985-03-27
Abstract: PURPOSE:To prevent dropping of return spring reliably through release bearing by functioning respective section while covering the spring engaging groove with release bearing.

Title: Digital servo control system for suppressing oscillation at time of stop
Inventor: SAKAMOTO KEIJI
IPC: G05D3/12
Filed: 1990-03-15
Abstract: PURPOSE:To reduce oscillation by executing position correction by using the velocity feedback data of high resolution. CONSTITUTION:The number of velocity feedback pulses from a detector 4 is stored in a register (a) as data fa and position feedback data fb from a DMR means 5 is stored in a register (b). An interpolating means 6 multiplies a constant Kp/N, for which a position gain Kp is multiplied with a DMR ratio 1/N (N=fa/fb) to a position deviation correcting value epsilon' obtained by an interpolating means 7, and a velocity deviation correcting value Vc2 is obtained. A normal velocity command Vc1 is calculated by multiplying the gain Kp to position deviation epsilon and a corrected velocity command Vc is obtained by subtracting the correcting value Vc2. In such a way, a velocity control part 2 executes a velocity control loop processing. Thus, even when the oscillation is generated when stopping a servo motor, the amplitude can be suppressed within the + or -1 unit of the velocity feedback data and the oscillation can be reduced and suppressed.

Title: Electronic wrist watch
Inventor: YAJIMA TOYOHIKO
IPC: H03K17/96
Filed: 1982-04-16
Abstract: PURPOSE:To improve the reliability in the operation of a touch switch along with a lower power consumption by turning ON or OFF a touch switch mechanism according to the operation of a switch while the inputs by simultaneous operation of a plurality of the touch switches are nullified to generate an alarm. CONSTITUTION:When a switch 6 is turned ON, transistors 10, 12, 16 and 17 are controlled by a high level output through FFs 21 and 22 and a low level output via an inverter 26 so that the input with switches 7 and 8 through a touch switch and comparators 3a and 7 and 3b and 8 is validated to form switch signals SW1 and SW2. Therefore, when the switches 3a and 3b are not used, the switch 6 is turned OFF to prevent useless power consumption. On the other hand, when the switches 3a and 3b are operated simultaneously by mistake, AND gates 24 and 25 are closed by a low level output through an AND gate 15 and an inverter 18 to generate no erroneous signals SW1 and SW2 while an alarms is generated from a speaker through a sound generation circuit 19. In this manner, the reliability in the operation of the touch switch can be improved.

Title: Photodetecting circuit
Inventor: OZAWA MASAYUKI
IPC: G01P3/486
Filed: 1984-04-02
Abstract: PURPOSE:To prevent a photoelectric crank angle sensor from malfunctioning owing to key switch chattering generated at the start of an engine by providing a constant voltage power source detecting circuit in a detecting circuit, and fixing a signal output when a voltage is abnormally low. CONSTITUTION:A constant voltage is obtained from an external power source VB through a resistance RB and a Zener diode DZ1 to turn on a light emitting diode D11, whose light is photodetected by a photodetecting diode D21. A voltage V<-> and a voltage VB<+> obtained through the division of resistances R3 and R4 are compared by a comparator C and a transistor Tr1 is operated to obtain an output E01 corresponding to the cylinder signal of the engine. An output E02 corresponding to the rotational angle signal of a crank shaft is the same. If a key switch generates chattering, the voltage VB rises from 0 to VB2 and the output enters an oscillation state. For the purpose, the constant voltage power source detecting circuit consisting of a Tr2 and a Zener diode DZ2 is connected between the Tr1 and a constant voltage circuit and then the output E01 never enters the oscillation state even if the source voltage rises from 0 to VB2, so that a sensor for an automobile which has superior use environment is obtained.
