IPC: G06F3/06
Filed: 1993-01-07
Abstract: PURPOSE:To improve the responsiveness of a user program by completing write/ read processing within irreducibly minimum time in a duplex disk system for recording the same data while overlapping them in two disk devices. CONSTITUTION:When an access request is issued, a request cylinder calculating means 11 calculates the position of a cylinder to make access. A request cylinder comparing means 12 compares the calculated cylinder position with the present cylinder position of each disk and specifies the disk for which the cylinder to mark access is much closer to the present cylinder position. Then, the request is issued to a data input/output means 15 so that an input/output instruction can be executed to the specified closer disk. Further, the request is issued to a control information output means 16 so that control information can be written in the disk for which the cylinder to make access is far away from the present cylinder position.

Title: Logic circuit simplifying device
Inventor: NISHIO SEIICHI
IPC: G06F17/50
Filed: 1991-01-10
Abstract: PURPOSE:To reduce the scale of a logic circuit after simplification by comparing the existing simplification with the conventional simplification using the same simplification rule without stopping simplification on a half-way due to local conversion. CONSTITUTION:A simplification rule matching part 3 checks the application for simplification rule stored in a simplification rule storage part 2 against the circuit parts constituting the logic circuit. When the simplification rule can be applied, the gate of this circuit part is not eliminated to be stored in an elimination gate storage part 4 as a gate to be eliminated. At the same time, the elimination gate storage part 4 writes '1' in an elimination flag corresponding to the gate in the logic circuit data stored in the circuit data storage part 1. Even to the other circuit parts containing the gates the application for the simplification rule is checked. After checking the application for the simplification rule against all circuit parts, all the stored gates are eliminated in a gate elimination part 5.

Title: Video recorder
Inventor: KOMORIYA RYUICHI
IPC: H04N7/01
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To attain simultaneous recording of plural video images different from the broadcast systems by converting the plural video images different from the broadcast systems into a reference system of the video signal and taking phase synchronization. SOLUTION: Broadcast system discrimination circuits A5, B6 discriminate a broadcast system of input signals A, B. When the two broadcast systems are the same, a control circuit 7 throws a SW9 to the position of a terminal (a) and a SW10 to the position of a terminal (d). Then the signal B is fed to a frame phase matching circuit 4 to take phase synchronization with the signal A based on a synchronizing signal of the signal A separated by a synchronizing separator circuit 3 and the resulting signal is modulated by a Y/C signal processing circuit B2 and the result is outputted to a recorder.  On the other hand, when the two broadcast systems differ, the signal B is given to a system conversion circuit 8, in which the signal is converted into the broadcast system of the signal A, the SW 10 is thrown to the position of a terminal (c), the signal B is given to the circuit 4 and modulated by the circuit B2 and outputted to the recorder. Thus, it is possible to record the signals A, B simultaneously by the video recorder in both the cases.

Abstract: PURPOSE:To prevent double sheet feed by furnishing a ridge on the stacking table of a piled sheets separator device to be used with a printer etc., in which the undermost sheet to be sent out by a trigger roll is separated from the residual sheets by allowing the sheet to fall when its trailing edge is going to pass the top of said ridge. CONSTITUTION:A ridge 10 is furnished at a certain appropriate place of a sheets stacking table's floor plate 2, perpendicular to the direction in which the sheet is transported, and thereby the rear parts of the piled sheets 4 are heaved from the floor plate 2 afloat. The location of this ridge 10 shall be so determined that the trailing edge of the undermost sheet 11 will pass this ridge 10 when the sheet 4 is sent off by a trigger roll 1 to a pair of feed rolle 9 through a gap 8. Thus the undermost sheet 11 sent out a little by the trigger roll 1 falls down onto the floor plate 2 by its own weight immediately after its trailing edge passed the top of the ridge 10 to be separated from the residual sheets.

Title: Internal-combustion engine with supercharger
Inventor: TAKAMIYA ENNOSUKE
IPC: F02B33/44
Filed: 1980-01-14
Abstract: PURPOSE: To enhance reliability and safety of the operation of the supercharger by providing a bypass control valve which operates as a fail-safe for a waste-gate controlling valve by cooperating with a bypass valve which prevents the supercharging pressure on the downstream side of a compressor from rising, at the time of deceleration.  
     CONSTITUTION: During operation of an engine 2, when an exhaust-gas turbine 4 is driven by exhaust gas, intake gas is pressurized by a compressor 6 and fed into a combustion chamber. When the engine speed is increased and the supercharging pressure exceeds a preset limit, the pressure of the compressor 6 fed through a passage 16 into a pressure chamber 12 of the waste-gate controlling valve 11 moves a valve member 14 downward through a diaphragm 13, thereby opening a bypass passage 10. At the time of deceleration, a large negative pressure of intake is fed into a negative-pressure chamber 20 through the bypass valve 18, and a plunger 19 is moved downward against the force of a spring 21, thereby opening a bypass passage 17. In this case, the bypass valve 18 is controlled by a control valve 26 having a valve 37 which is operated by the pressure in a pressure chamber 28.

Title: Bonding method for flip chip element
Inventor: YAMAMOTO SUSUMU
IPC: H05K3/34
Filed: 1986-01-09
Abstract: PURPOSE:To obtain solder bonding having high heat resisting stress property with one soldering process, by coupling a chip lifting jig having a bimetal function on the back surface of the chip of a flip chip element with bumps beforehand in a heat transfer mode. CONSTITUTION:A process starts under the state solder bumps 2 of a chip 1 are contacted with a preliminary solder layer on the side of a substrate 3 and held at an initial low temperature state of a soldering process. When temperature is increased to a temperature at which solder is fused by heating, the parts of a lifting jig 5, which are protruded to the right and left from the chip 1, are curved downward owing to a bimetal effect. With the tips of the jig as supporting points, the chip 1 is lifted upward from the substrate 3. The solder bumps 1 in the fused state are also extended. A height H of a solder bonded part becomes higher than an initial height (h) of the bump 2. When external heating is stopped, the solder bonded part is solidified with its height held at H. At the same time, the jig 5 is returned to the original state. Thus, strain, which is yielded in the bumps 2 resulting from thermal stress, can be suppressed. Such a solder bonded part can be obtained.
