Title: Liquid helium supply device
Inventor: TANAKA MINORU
IPC: G05D16/00
Filed: 1982-02-10
Abstract: PURPOSE:To keep pressure constant, by connecting a liquid helium supply tank side pipe being at gas outlet with a bypass pipe with valve. CONSTITUTION:A helium supply side pipe 14 with valve and a helium supply side pipe 12 are connected at the outlet. A gas pressure PO+DELTAP is applied to a reducing valve 8 side pipe 11, a valve 15 of the pipe 14 is opened to attain the gas pressure of PO quickly through both the paths. Simultaneously, the pressure of the pipe 11 is decreased to the PO, and the valve 15 is closed to keep the pressure of the pipe 12 at PO+DELTAP. When the pressure of the pipe 12 is reduced a little below the PO, a float 13 goes upward, the gas is fed to the helium supply tank 1, and when the gas pressure of the pipe 12 attains PO+DELTAP, gas supply is stopped to allow to perform the switching operation.

Title: Digital differentiation analysis method and device
Inventor: ASAKAWA YUKIO
IPC: G06F7/64
Filed: 1980-02-20
Abstract: PURPOSE:To prevent an offset error, by controlling an input operation to a Y register with the state of operation a digital differentiation analyzer (DDA). CONSTITUTION:At the start of the i-th operation, since the previous value yi-1 is stored in the Y register 20, this is read out at the latch 21. This is the A input of the adder 27. DELTAyi is set to the B input of the adder 17. Thus, yi+1+DELTAyi is output at the output of the adder 17, and this is the B input of the comparator 18 and the selector 19. To the A input of the both, the value of the R register is set via the latch 25. The comparator 18 makes judgement of B>=A, 0<B<A,B<=0, for 3 cases and the state signal Ccp is given to the selector 19. The selector 19 determines depending on the state of Ccp that the initial value r0 is given to the Y register, yi-1+DELTAyi or zero is given.

Title: Cartridge sensor
Inventor: TSUKADA EIJI
IPC: G11B15/675
Filed: 1983-02-08
Abstract: PURPOSE:To eliminate the effect due to a mechanical or aging factor by detecting the quantity of electricity which is produced by a loading action of a cartridge. CONSTITUTION:A current detecting part 3 is connected between a cartridge opening device 1 and a motor driving part 2. Then a driving motor is set under a load state when a loading switch 4 is turned on after a cartridge is loaded to a magnetic device. Thus a load current is detected by the part 3, and the cartridge is detected from the difference between the no-load current and the load current. The quantity of electricity produced by a cartridge loading action is detected without using a miniature switch which works mechanically with a loading action of cartridge. Thus it is possible to eliminate the effect due to a mechanical or aging factor.

Abstract: PURPOSE:To form an electronic counting device having a simple constitution and high reliability by a method wherein the correct number of striking is attained without setting of the initial number of striking even when a power source is made or when time correction for 1hr or more is conducted. CONSTITUTION:An hour hand wheel 1 rotates, and the end 5a of a contact piece 5 contacts with a common electrode 3, while the end 5b thereof contacts with a pattern electrode. Thereby a switch 8 is closed. At this moment, a pulse signal is generated from a one-shot pulse generating circuit 14, and thereby a counter 12 is reset. Since pattern electrodes 4d-4m are set to have central angles three to twelve times larger than that of the pattern electrode 4b, respectively, the number of pulses delivered from an AND circuit 10 becomes three to twelve times larger than five, and accordingly, an output corresponding to three to twelve o'clock is generated at output terminals Q1-Q4 from an encoder 13. This means that a time period wherein the end 5b of the contact piece 5 contacts with the pattern electrode 4m and thereby the switch 8 is closed is 48min wherein the hour hand wheel 1 rotates around the central angle of 24 degrees, and that sixty clock pulses pass through the AND circuit in the meantime. The sixty signals generate outputs ''0'', ''0'', ''1'' and ''1'' corresponding to twelve o'clock in the encoder 13. Receiving these outputs, a time-informing device generates corresponding time-informing sounds.

Abstract: PURPOSE:To prevent creep of a vehicle effectively, by adding an oil controlling mechanism associated with a temperature detector to a clutch selecting valve of a gear shifting means combined with a hydraulic torque converter. CONSTITUTION:Pressure oil is supplied from an oil pressure control mechanism 30 to clutches C1-C3 combined with a hydraulic torque converter. A changeover valve 51 is provided in oil passages 62, 63 connected to the first-speed clutch C1, and another changeover valve 52 is controlled by a solenoid 36 that is excited by a thermocouple 58 for detecting the oil temperature. When the thermocouple 58 detects that the oil temperature is higher than a reference value, oil pressure acted to the clutch C1 is lowered to a great extent by the changeover valve 51 so as to prevent creep of a vehicle. When the temperature is low, on the other hand, oil pressure acted to he clutch C1 is lowered only slightly by the changeover valve 51, so that creep of the vehicle is caused again. Further, when the vehicle speed is higher than a prescribed value or when an accelerator pedal is depressed, the changeover valve 51 is closed to raise the oil pressure acted to the clutch C1.

Abstract: PURPOSE:To reduce the combustion noise of an engine by restricting the amount of injection at early period in valve opening, in a hole-type fuel injection valve. CONSTITUTION:The first-stage injection hole 11 and the second-stage injection hole 14 are formed on a nozzle body 2. When a needle 3 lifts, the tapered part 15 of the needle 3 is separated from a seat part 10, and the injection hole 11 at the first stage is opened, and fuel jetted-out. Since the cylindrical part 16 of the needle 3 has a certain length, the needle 3 is in engagement state with a fitting part 12 at this time, and fuel is not jetted-out from the injection hole 14 at the second stage. When the needle 3 lifts, the cylindrical part 16 of the needle 3 slips-off from the fitting part 12, and fuel flows into a liquid sink 13 and jetted-out from the injection hole 14 at the second stage. In this case, fuel is jetted-out from both of the injection holes 11 and 14 at the first and the second stages respectively. When the diameter of the injection hole 11 is made smaller than that of the injection hole 14, noise can be reduced.
