Title: Pressure regulator valve for automatic transmission
Inventor: TAKEUCHI MASAHIRO
IPC: F16H63/02
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a pressure regulator valve which is not influenced by a temperature change. SOLUTION: A spool 1 is inserted into a spool hole 9 of a control valve body 30, and a hollow cylindrical sleeve 4 brought into close contact with its inner peripheral surface is arranged in a plug valve hole 8. A first seal member 7 existing on the opening side of the plug valve hole 8 is constituted of the same aluminium material as the control valve body 30, and seals the plug valve hole 8. In a second seal member 5, a circumferential surface is brought into close contact with the inner peripheral surface of the plug valve hole 8, and an end surface receives a spring 3, and the other end surface is brought into close contact with an end surface of the sleeve 4 by reaction of the spring. A plug 20 is slidably installed in the sleeve 4, and its tip is constituted so as to capable of coming into contact with the spool 1.  Therefore, the first seal member 7 can seal an opening of the plug valve hole 8 without being influenced by a temperature change, and a line pressure drop brought about by reduction in driving force applied to the plug by leakage of oil can be prevented.

Title: Noise canceller circuit
Inventor: YAMADA SHINICHI
IPC: G11B20/02
Filed: 1989-08-25
Abstract: PURPOSE:To improve the quality of a picture by detecting an edge part to eliminate a noise component left in the edge. CONSTITUTION:The circuit consists of a signal input terminal 1, adders 2, 6, delay circuits 3, 8, inverting amplifiers 4, 10, a high pass filter 5, an edge detection circuit 7, an edge region gate circuit 9, and a signal output terminal 11. Since a noise component inverted with the edge region onto an original video signal is added at the adder 2, the noise component superimposed on the edge region is cancelled and eliminated. Thus, when the video signal passing through a conventional noise canceller circuit is supplied as the original video signal, the noise component left in the edge part of the original video signal is effectively eliminated. Then the video signal with a high S/N is obtained and high picture quality of the picture is attained.

Title: Redundant decoding circuit and its control method
Inventor: KYO DAKIN
IPC: G11C29/04
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption at the time of stand-by by providing a comparator, driving circuit, a pulse generator, and the like, and inactivating a nonselect signal automatically after burst read/write operation thereby controlling a current circuit leading to redundant decoding. SOLUTION: A pulse signal CYC4B from a pulse generator 20 in a redundant decoding circuit 200 has a low level at the time of starting normal read/write operation and goes high level at the end of normal read/write operation. The pulse signal CYC4B is activated to low state only during normal read/write operation and inactivated automatically upon elapsing a sufficiently long time for executing the read/write operation. The pulse signal CYC4B is inactivated when a semiconductor memory having the redundant decoding circuit 200 makes a transition to stop mode. Consequently, generation of current path is prevented surely in stop mode.

Filed: 1986-09-19
Abstract: PURPOSE:To manufacture a durable discharging electrode with simple constitution by sticking a dielectric which has buried electrodes for AC voltage application and the other dielectric with a bare electrode on each other. CONSTITUTION:The buried electrodes 11 and 12 provided on the dielectric 10 are covered with an adhesive 13 and the other dielectric where the bare electrode 15 is fitted is adhered to constitute the discharging electrode 1. When an AC voltage which is higher than a specified discharging start voltage is applied from a power source 16 to between the electrodes 11 and 12, discharging 17 is caused to generate a positive and a negative ion alternately. A bias voltage is applied to the bare electrode 15, so ions having a desired polarity are extracted toward a member 2 to be electrified and the member is charged. Thus, the different dielectrics are only stuck together to simplify the process and has superior mass-productivity, and neither curving nor size variation occurs and the electrodes are buried, so the durable discharging electrode is manufactured.
