Title: Method for acceleration test of semiconductor integrated circuit
Inventor: OSHITA CHIHIRO
IPC: G01R31/26
Filed: 1987-06-25
Abstract: PURPOSE:To suppress the fluctuation in power source voltage and to prevent the breakdown of integrated circuits by adopting the constitution consisting in dividing the plural integrated circuits to be tested to plural sets and impressing bias signals having different phases between respective sets of the circuits. CONSTITUTION:The plural semiconductor integrated circuits IC 41 which are to be tested and are mounted on a test board are divided to plural sets each set consisting of a prescribed number. The bias signals V1, V2 are directly impressed to the respective circuits IC 41 of the set 4a of the ICs to be tested. The bias signals V3, V4 which are delayed by passing the signals V1, V2 respectively through delay circuits 2a, 2b so as to have the phases different from the phases of the signals V1, V2 are impressed to the circuits ICs 41 of the set 4b of the ICs to be tested. The tests are then carried out. The peak of the power source current I1 of the set 4a of the ICs and the peak of the power source current I2 of the set 4b of the ICs appear in different periods in this case and, therefore, the power source current from a power source circuit 3 is dispersed with time and the peak values can be suppressed. The fluctuation in the source voltage is thus suppressed.

Title: Fuel injection control device for internal combustion engine
Inventor: OGAWA TAKASHI
IPC: F02D45/00
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress the abnormal increase of a cylinder pressure during the occurrence of abnormality to a fuel injection valve. SOLUTION: High pressure fuel is stored at a common rail 3 and fuel is fed to the fuel injection valves 1a-1d of a diesel engine 100 through the common rail. A control circuit 20 decides the occurrence of abnormality to some fuel injection valve based on a common rail fuel pressure detected by a fuel pressure sensor 31. During detection of abnormality, such as the impossibility of a stop of fuel injection, an EGR valve 107 provided in an EGR passage 105 to interconnect an exhaust passage 103 and each cylinder intake port of an engine is fully opened, and an amount of exhaust gas returned to the intake port is increased.  This constitution remarkably reduces a ratio of fresh air sucked in each cylinder without reducing an intake pressure, and suppresses the abnormal increase of the cylinder pressure of a cylinder, to which quantities of fuel is fed due to abnormality of the fuel injection valve occasioned by suppression of combustion in the cylinder, without the occurrence of an engine brake due to lowering of an intake pressure.

IPC: B21B45/02
Filed: 1981-10-09
Abstract: PURPOSE:To constantly keep a water level of a water storage tank by a pressure in a gaseous pressure accumulator, and to reduce a capacity of a water pump and running cost, by providing a gaseous pressure accumulator having an internal pressure controlling mechanism which presses a part of the surface of the stored water in the storage tank. CONSTITUTION:A level gauge 8 detects the change of a water level H changing with a supply of cooling water, and a computor 9 gives a instruction of opening or closing to a valve 7. Then the water level H is kept constant by a change of a pressure Pa in an accumulator 6 because the opening and closing of the valve 7 is controlled. At this time, the speeds of a pump P and a blower B are required to be as constant as possible in operation and maintenance, except when a kind of steel and/or sheet thickness, etc. are remarkably changed causing the necessity of a remarkable change of a target cooling temperature. At that time, the speeds of the pump and blower are determined by a calculation of  computer 9 basing on an information 1 previously inputted to it about said speeds. Next, a supplying water quantity is controlled by closing all the number (n) of valves 10 or half of them or opening all of them. At this time, the capacity of the pump is reduced because only the water for cooling is circulated.

     CONSTITUTION: Small bores 12 are provided in a type wheel 11 relative to types 10 provided on the circumferential surface thereof, and magnetic materials 14 of the same size are buried in the small bores 12. The depths of the small bores 12 are varied with corresponding types 10. Accordingly, the magnetic forces of the magnetic materials 14 at the circumferential surface of the type wheel 11 are different.  Consequently, the types 10 can be identified, and the presence or absence of the  types 10 in a predetermined position can be detected. In order to detect advance,  shifting and correctness of types 10 on the type wheel 11, a detector 16 including a  magnetic resistor element is provided above the orbit to be drawn by the type wheel  11. Thus, a timing signal representing that the detector 16 is in opposition to any  one of the small bores 12 and magnetic materials 14 is extracted from the shaft of  the type wheel 11 or some other portion thereof. This allows a code pattern to be  kept undamaged.

Abstract: PURPOSE:To sufficiently remove dust before a head is brought into contact with the information face of a recording medium. CONSTITUTION:When the recording medium 2 is inserted into the device, the recording medium 2 is loaded on a medium driving motor 1 by a medium loading means. When the recording medium 2 is inserted, a medium detecting signal is outputted to a motor control means 11 by a medium detecting means 5. ACL signal which is turned 'true' for a prescribed time by the above medium detecting signal is outputted to a logic circuit 12 and the medium driving motor 1 by the motor control means 11. Receiving 'true' of this CL signal, the medium driving motor 1 is turned to 'ON' state by the logic circuit 12. Receiving 'true' of the CL signal, the medium driving motor 1 is rotated twice as fast as the normal speed at the time of a reproduction, and the recording medium 2 is rotated. When the recording medium 2 is rotated, the information face is wiped by a liner, and the dust on the information face is removed. After the elapse of a prescribed time, the CL signal from the motor control means 11 is turned 'false', the medium driving motor 1 is rotated at the normal speed at the time of the reproduction, and the recording medium 2 is rotated at a reproducing speed.
