Title: Hydrogen occluding body
Inventor: WAKAO SHINJIROU
IPC: F17C11/00
Filed: 1979-05-25
Abstract: PURPOSE: To provide an H 2  occluding body having high H 2  occluding and releasing speed, a large amount of H 2  to be occluded and released and high heat conductivity and free from metal scattering and deposition by filling much H 2  occluding hydride or H 2  occluding metal into a cellular metal porous body.  
     CONSTITUTION: Much H 2  occluding hydride or H 2  occluding metal is filled into a cellular metal porous body formed into a spongy three-dimensional net. Thus, high heat conductivity is obtained, and the H 2  occluding metal filled into each cell of the porous body is trapped in each cell and becomes difficult to move. Accordingly, the early-stage filling state and the early-stage void state are maintained for a long term to maintain stable H 2  occluding and releasing speed and a stable amount of H 2  to be released. By mixing heat conductive additives such as Cu, Al and graphite or a viscoelastic substance into the hydride or the H 2  occluding metal and filling this mixture into the above-mentioned porous body, metal powder is further prevented from falling off and scattering, and the heat conductivity from deteriorating.

Title: Memory redundancy circuit
Inventor: JIYAN DOUBUAN
IPC: G11C29/00
Filed: 1995-02-28
Abstract: PURPOSE: To shorten initialization time by inhibiting or invalidizing the operation of a defective address memory corresponding to a signal from an inhibition circuit provided at a redundant circuit when there is no defect in a main memory. CONSTITUTION: An address decoder DEC receives an address ADD and access to the specified block of a main memory MP is performed. When no defect is detected in the entire main memory MP by a test, a signal INH is sent from an inhibition circuit IN to a defective address memory CAM and its operation is made inactive. When an enable signal VAL is outputted to the circuit IN without transmitting this signal INH, the address ADD transmitted to the memory CAM as well is compared with all the stored defective addresses. When any address is coincident, the address memory block of the main memory MP is prevented from being addressed by a signal ADR outputted from the memory CAM and in place of that block, the block of the redundant memory MR is addressed.

Title: Phase comparator and pll circuit
Inventor: NOTANI HIROMI
IPC: H03L7/093
Filed: 1994-04-01
Abstract: PURPOSE:To obtain a phase comparator with simple configuration in which phases are compared at a high speed. CONSTITUTION:A NAND gate of the precharge system comprising transistors(TRs) Q35-Q37 compares phases.

IPC: C30B15/02
Filed: 1981-05-01
Abstract: PURPOSE: To provide an apparatus for the continuous preparation of a single crystal having long length and high quality, by placing a crylindrical barrier in a crucible so as to divide the liquid surface with the barrier and allow the flow of the molten liquid at the bottom of the crucible, feeding the raw material to the molten liquid outside of the cylindrical barrier, and pulling up the single crystal from the molten liquid in the barrier.  
     CONSTITUTION: A cylindrical barrier 4 is placed in the crucible 3 so as to divide the surface of the liquid, and the single crystal 1 is pulled up under toation from the molten liquid 2 in the barrier 4. The raw material 8 in the hopper 7 is fed to the molten liquid 2 in the crucible 3 continuously or intermittently by the opening and closing operation of the shutter 9. The barrier 4 inhibits the propagation of the wave of the molten liquid 2 caused by the drop of the raw material 8 in the molten liquid 2, and suppresses the thermal influence of the raw material 8 immediately after feeding which may cause the direct interference to the growing interface of the single crystal 1. A long single crystal can be prepared by feeding the raw material 8 to the crucible while pulling up the crystal 1.

Abstract: PURPOSE:To prevent the occurrence of the bounce of a valve body by liquidtightly partitioning a space part where an armature part moves in a body into two fuel chambers through the armature part, and just before the valve body abuts against the body during the valve closing motion of the valve body, making impulsive force act to the valve opening movement of the valve body. CONSTITUTION:When an electric current is applied to a solenoid 2, electromagnetic force is generated, and an armature part 44 is attracted downward by magnetic force, and a needle valve 4 is therefore lowered against a spring 3 and seated on a valve seat 43. In this case, a damper chamber (the first fuel chamber) 8 under the armature part 44 is reduced in its volume and pressurized, and the fuel in the damper chamber 8 leakingly flows through a fuel relief face 47 and groove 48 into an armature part (the second fuel chamber) 10. But when the impulse face 49 of the upper part of the armature begins to lie on the upper face 17 of a body, the fuel relief groove 48 is closed by an armature guide face 16 to restrict the leaking flow of the fuel for making impulsive force act to the valve opening movement of the valve 4.

Abstract: PURPOSE:To obtain a memory device superior in packaging efficiency by providing a substrate having a short-circuit bar which short-circuits substrates having the memory correcting function or prescribed pins. CONSTITUTION:When it is unnecessary to add the error correcting function to a memory, a short-circuit bar 14 is connected to a connector 12 of a printed circuit board 10. As the result, control busses 4A and 4A' and data buses 4B an 4B' are short-circuited to operate the memory 2 without error correction.

As the result, busses 4A and 4B are connected to busses 4A' and 4B' through an error correcting circuit 5, and an address bus 4C is connected to a memory 5 for check bit. Thus, the error correcting function is added or not added to the memory 2 according as the printed circuit board 13 is connected to connectors 11 and 12 or the short-circuit bar is connected to the connector 12.

Filed: 1978-05-31
Abstract: PURPOSE: To let an AC motor to be stalled and to regulate its speed at a constant acceleration in the range of all working freqencies by giving smaller values to V 1 /f 1  (V 1 : AC input voltage, f 1 ; primary frequency) then the rated value of the AC motor in the region where the f 1  is small.  
     CONSTITUTION: Speed prescription signals from a speed determiner 24 are transmitted, as they are, to a frequency control circuit 26 through a speed control circuit 25, while they are given to a voltage control circuit 28 through a function generator 27 which outputs greatly small power when the prescription signal requires low speed. High frequency torque of the AC motor decreases and although higher harmonic elements included in the output current of a frequency converter are the same as they were, trickripples can be decreased.
