Title: Magnetic disk device
Inventor: KOKUBO NORIYOSHI
IPC: G11B21/02
Filed: 1986-07-14
Abstract: PURPOSE:To reduce guide shafts requiring a working accuracy and lower a cost by guiding a magnetic head movable carriage by one guide shaft. CONSTITUTION:When recording or reproducing a magnetic disk 13 mounted on a turn table 14, a pinion 3 is driven on a movable carriage 1 in the direction shown by an arrow X by a rotation of a motor 4, and a magnetic head 2 moves to a position opposed to a desired recording track. When moving the magnetic head 2, the movable carriage 1 made of PSS resin of a small friction factor horizontally smoothly moves because a sliding part 1c slides on a guide rail 5 with a low friction and a ball 16 rolls on a chassis 6. Since the movable carriage 1 is compact size and light weight, a burden of the motor 4 is reduced and it rapidly and stably moves. Since the movable carriage 1 is turned and energized making the guide rail 5 a turning fulcrum by a spring 18, no adjustment in engagement state of a rack 1a and the pinion 3 during assembling is required.

Title: Precision pressure regulating valve
Inventor: NAKAHARA KAZUO
IPC: G05D16/06
Filed: 1994-07-18
Abstract: PURPOSE:To acquire high responsiveness or constant characteristics. CONSTITUTION:A space 38 for regulating is partitioned into a pressure equalizing chamber 47, atmospheric chamber 48 and regulating chamber 49 by two diaphragms 45 and 46, and the aperture of a valve element 43 is decided through a valve stem 57 corresponding to the balance between the pressure of air 61 for regulating supplied to the regulating chamber 49 and that of gas 73 on the side of an exit part 33 to flow into the pressure equalizing chamber 47 so that pressure on the side of the exit port 33 can be regulated constant. In this case, regulated pressure is set by air pressure so that high responsiveness can be provided corresponding to the flow rate change of gas 73. On the other hand, the constant characteristics can be obtained by the air 61 for regulating at fixed pressure regardless of the flow rate of gas 73 or pressure on the side of an entrance port 32 so that high regulating accuracy can be obtained. Further, since the atmospheric chamber 48 is formed between the pressure equalizing chamber 47 and the regulating chamber 49, even when either the diaphragm 45 or 46 is damaged, the air 61 for regulating is prevented from being mixed with gas 73.

IPC: H04B1/18
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a tuning function and a reception band function by simple circuit constitution by providing two functions which use a varactor diode as a variable capacity element and as an ordinary diode respectively. SOLUTION: The outputs from tuning circuits T1 and T2 are led out as balanced outputs from both ends and supplied to a balanced input mixer circuit. When switches S1 to S4 are as shown in the figure, varactor diodes VD1a and VD1b are biased forward with a source voltage Vcc and the tuning circuit T1 is short-circuited. At this time, one varactor diode VD2a or VD2b is biased reverse with the tuning voltage supplied from a PLL circuit, so it has a capacity value matching the voltage, so that the tuning circuit T2 tunes to a desired frequency. Namely, the reception band determined by the tuning circuit T2 is obtained. When the switches S1 to S4 are placed in the state reverse to that in the figure, the states of the varactor diodes are inverted and the reception state determined by the tuning circuit T1 is obtained.
