Title: Controller for solenoid operated valve
Inventor: IIDA TATSUO
IPC: F01L9/20
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent the armature connected to an exhaust valve from repulsing from the electromagnet on the valve opening side attributable to the negative pressure inside the combustion chamber, and also to restrain the operating sound, during the execution of fuel-injection cut control with regard to the controller of a solenoid operated valve. SOLUTION: This solenoid operated valve 40 for driving a valve element 44 functioning as an exhaust valve is provided with an armature 74 connected to the valve element 44, an upper core 82 and an upper coil 80 arranged above the armature 74, and a lower core 86 and a lower coil 84 arranged below the armature 74. The valve element 44 is open or close driven by alternately supplying an exciting current to the upper coil 80 and the lower coil 84. During the execution of fuel-injection cut control, at the time of opening of the valve element 44, when the armature 74 is released from the upper core 82, the period of time for supplying a release current to the upper coil 80 is made longer than that at the normal operation.

Title: Digital integrated circuit
Inventor: SATO MITSURU
IPC: H04N1/032
Filed: 1990-11-15
Abstract: PURPOSE:To enable potential retention capacity to be improved without increasing an occupation area of a circuit by providing a feedback circuit with a third switching means between a first potential retention part of a shift register and a second potential retention part of a latch circuit. CONSTITUTION:When a data signal is given to an input D, the signal D is read by closing of a transfer gate 1 controlled by a clock signal C, is inputted to an inverter 7 through a transfer gate 5 where an inversion signal according to an inverter 3 opens or closes alternately with the gate 1, and then a reinversion data signal is fed to an output. While the gate 5 is open, a transfer gate 15 is closed and a feedback circuit connecting an input side of the inverter 7 and an output side of an inverter 13 conducts, thus enabling an output potential of a shift register S to be retained constantly and preventing a function of a digital circuit from being lost even if a frequency of a clock signal is low. Therefore, by installing the gate 15 newly, data retention capacity can be enhanced without increasing circuit occupation area.

Title: Pachinko game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko game machine which can easily check a valid duration for particular balls after variable prize winning ball equipment is closed. SOLUTION: Measurement of valid time signal is started from the point of time of the establishment of particular conditions for a variable prize winning ball equipment 20 to change to the second state and ended when any of the following condition is met. Firstly predetermined time t4 has passed from the point of time when the particular conditions are established. Secondly starting ball detectors 5a to 5c detect balls before the predetermined time t4 passes and during starting valid duration. Thirdly a particular ball detector 48 detects balls before the predetermined time t4 passes. In this way it is possible to learn by the length of the interval of a valid duration signal that starting ball detection and particular ball detection have been done before the predetermined time t4 passes, when there have been such detection during a particular ball valid duration and as a result it is made easier to check a particular ball valid duration after the variable prize winning ball equipment 20 is closed.

Title: Semiconductor device
Inventor: ONISHI HIDEAKI
IPC: H01L29/786
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To sufficiently draw out performance of a thin film SOI device of sub-quater micron, by a method wherein a film thickness of a high fusion metal silicide is formed so as to thin more than that of a silicon thin film of a channel region and be half or more a silicon film thickness of the channel region. SOLUTION: In a semiconductor device, a film thickness Y of a high fusion metal silicide (TiSi2 ) 8 of a source/drain part of an SOI device is set in the range of 0.5X<=Y<X with respect to an SOI film thickness X (X<=50 nm). When holes generated in a drain part flow in a source, the TiSi2 8 accelerates extraction of the holes from a channel part centering recombination. The film thickness Y of the TiSi2 8 of the source/drain part of the SOI device is set 1/2 or more times as much as the film thickness X of a SOI layer of the channel part. As a result, it is possible to suppress occurrence of kink characteristic and reduce parasitic resistance of the source/drain.

Title: Exciting pulse generating method for pulse transformer
Inventor: AZUSAZAWA NOBORU
IPC: H02M1/08
Filed: 1991-11-26
Abstract: PURPOSE:To substantially equalize the product of exciting voltage and time on the positive and negative sides of a pulse transformer by generating exciting pulses synchronously with the rising of input pulse and comparing the level of exciting pulse at the time of falling of input pulse with that at the time of generation. CONSTITUTION:Output of a pulse transformer 27 is rectified through a rectifying circuit 28 and amplified to produce a wide gate pulse which is then applied onto the gate of a thyristor 7a. When the pulse transformer 27 is excited according to the wide width gate pulse (a), excitation is stopped at time t4 and thereby the excitation is increased on the positive side for an exciting time T4 immediately before the time t4. When the excitation is not stopped at time t4 but sustained through utilization of charge/discharge characteristics of series circuit of a capacitor 32 and a resistor 31, the pulse transformer 27 is excited on the negative side for a time T5 corresponding to the time T4. Consequently, the difference of the product of exciting voltage and time can be substantially eliminated between the positive and negative sides of the pulse transformer 27 which is thereby prevented from saturation.
