Title: Shutoff valve
Inventor: SUGIYAMA MASAKI
IPC: F16K17/36
Filed: 1992-07-03
Abstract: PURPOSE:To enhance impact resistance required for holding a valve element by enabling formation of a magnetic bypass line having small magnetic resistance and allowing magnetic flux generated by a solenoid coil to lead to a second yoke via a third yoke, in a gas shutoff valve for preventing accidents of gas. CONSTITUTION:While a valve element 9 is open, one end of a plunger 3 is made to abut to a core 2 and the electromotive force of a permanent magnet 1 forms a magnetic circuit 24 connecting a core 2, the plunger 3, a first and second yoke 4, 5 and the permanent magnet 1. At an attracting surface 23 the plunger 3 is attracted and held to the core 2 against a spring 8. Also, a second magnetic circuit 27 is formed which connects the core 2, a third and second yoke 6, 5 and the permanent magnet 1. When an electromotive force opposite to that of the permanent magnet 1 is generated by application of electric power to a solenoid coil 7, magnetic flux generated by the solenoid coil 7 flows through a magnetic bypass line leading from the core 2 to the second yoke 5 through the third yoke 6 so that the valve element 9 is pressed into contact with a valve seat 10 and kept closed.

Title: High voltage detecting circuit
Inventor: JINBO SHINICHI
IPC: G01R31/3185
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for increasing a high voltage even when an external power source voltage is increased. SOLUTION: A divider circuit 26 divides an external power source voltage extVCC at a 1st dividing ratio. A divider circuit 10 divides a high potential SV at a 2nd dividing ratio smaller than the 1st dividing ratio when the external power source voltage extVCC is lower than a reference potential, and divides the high potential at a 3rd dividing ratio between the 1st and 2nd dividing ratios when it is higher than the high potential SV. A comparator 20 outputs a high voltage detection signal SVIH when an output potential V10 of the divider circuit 10 is higher than an output potential V26 of the divider circuit 26. Since the dividing ratio of the divider circuit 10 is varied according to the external power supply voltage extVCC, it is unnecessary to vary the high potential SV.

Abstract: PURPOSE:To improve accuracy of tracking at a level of a pilot signal having large amplitude by recording/reproducing the pilot signal in a track of a recording medium and making a bit line itself as the pilot signal using the prescribed code words. CONSTITUTION:Code words of disparity of each bit of a run pattern 0 generation circuit 1, a sync word 0 generation circuit 3, and an ID word 0 generation circuit 7 are generated at +5.

A period generating circuit 9 outputs signals which are inverted every bit numbers corresponding to frequency of a pilot signal. And data is recorded so that cumulative value increase and decrease period of disparity equals to a period of the pilot signal. Therefore, a system of narrow track width can be realized even if a pilot signal level is made high.
