Title: Reducing valve having bypath
Inventor: KONO TERUHISA
IPC: B60T8/26
Filed: 1984-10-17
Abstract: PURPOSE:To simplify the parts and to improve the reliability by providing a reducing valve for one system on a piston receiving the pressures in two systems in facing direction while stopping the function of reducing valve through motion of piston upon fault of other system. CONSTITUTION:Under normal operation of two systems, the cross-section of piston 5 is such as A=B>C thereby the piston 5 will stop at the left position because of the differential pressure receiving area. Consequently, the reduction valve 9 will execute normal pressure reducing function. Upon fault of second system at the inlet 2'. The piston 5 will move to the right because of the pressure difference. Here, an O-ring 15 of piston 5 will also move to the right to be deviated from the seal section of the bore 4 area B. Consequently, a bypath directly communicating between the inlet 2 and outlet 3 is formed to eliminate pressure reducing effect of reducing valve 9.

IPC: G06F9/30
Filed: 1991-08-06
Abstract: PURPOSE:To easily and accurately secure the recovery time with a microprocessor independent of the type and the operating frequency of the microprocessor and the presence or absence of an instruction CACHE. CONSTITUTION:When a freeze instruction is carried out, the immediate value included in the freeze instruction and stored in an immediate value register 1 is transferred to a counter value register 3. Then, with the start of a count- down operation of a subtraction counter 6 with the immediate value as the initial value in an executing cycle of the freeze instruction, a O-deciding block 7 decides a fact that the value of the counter 6 is not equal to O any more and then outputs the freeze signals to the control blocks 8 and 9. Both blocks 8 and 9 freeze their operations and hold the internal operations. At the same time, the blocks 8 and 9 output the signals to inhibit the start of the new bus accesses. Therefore the recovery time is easily and accurately secured.

Title: Magnetic bubble memory element
Inventor: TOYOOKA TAKASHI
IPC: G11C19/08
Filed: 1986-09-19
Abstract: PURPOSE:To prevent the extending of a magnetic bubble by providing a hair pin type generator to one side conductor pattern of conductor patterns consisting of upper and lower layers. CONSTITUTION:The conductor pattern consisting of upper and lower layers to sandwich an insulating layer at the section are used, and one side of the conductor patterns is made into a hair pin type and other side conductor is made close to the hair pin. To a hair pin conductor pattern 5 and a straight- lined conductor pattern 6 formed at other layer to cross and serially connect with the hair pin conductor pattern 5, a current pulse is impressed. Thus, at the vicinity of a rectangular part surrounded by conductor patterns 5 and 6 of two layers, the pulse magnetic field in the direction reverse to the bias magnetic field occurs. The pulse magnetic field inverts the magnetization of the bubble magnetic film of the lower layer and a magnetic bubble occurs. For the generated magnetic bubble, the extending of the bubble is prevented and the generating of the erroneous action can be eliminated by the magnetic field made by the straight-lined conductor pattern 6.

Title: Overload controller for induction motor
Inventor: IBORI SATOSHI
IPC: H02P27/06
Filed: 1986-09-19
Abstract: PURPOSE:To inhibit the trip of an inverter, and to improve the reliability of the inverter by gradually decreasing the output frequency and output voltage of the inverter by a predetermined time constant and suppressing the currents of a motor when the motor is in the state of overload. CONSTITUTION:In a control circuit section 7, current detecting signals IU, IV and IW are emitted by a current detector 9, and control is conducted by a microcomputer 10. When load is increased and a current detecting value exceeds a previously set allowance at that time, an inverter 2 determines the state of the overload of a motor 5, and begins to gradually diminish its own output frequency and output voltage. Progressive reduction is repeated and speed is decreased toward zero so far as overload continues. When overload is released in a progressive reduction process, however, the speed of the motor 5 is accelerated up to prescribed speed according to the previously selected time of soft start.

When the amount Q is equal to the capacity of the supplier 10 or less, only the supplier 10 is used. By this constitution, hot water at low and high temp. can be surely supplied and overshoot and undershoot can be prevented from occurring.

IPC: H01L27/08
Filed: 1983-11-21
Abstract: PURPOSE:To prevent the latch up by a method wherein diodes which by-pass the surge current are provided, with the parastic diode of a driver which drives the gate of a output transister in parallel. CONSTITUTION:A P<+>N<-> diode 22 and a P<->N<+> diode 23 are provided in parallel to parastic diodes 5, 6. It is better the resistor components of the diodes 22 and 23 are set up as small as possible by shortening the space P<+> and N<+> in the constitution, and due to this constitution most of the surge current coming through the capacitance flows through the diode 22 when (+) surge, and flows through the diode 23 when (-) surge, and accordingly the current flowing the diode 5 or 6 decreases and the occurrence of the latch up is prevented. The surge current flowing the diode 5 or 6 can be still more reduced by providing a resistance between the diodes 5, 6 and the gate of an N channel MIS transistor 2, and the preventing effect of the latch up can be improved.
