Patent JP-S622555-A (JP)
Title: Microwave transmitting circuit
Inventor: KAWAHARA TAKESHI
IPC: H01P3/08
Filed: 1985-06-27
Abstract: PURPOSE:To prevent the generation of mechanical gaps between surfaces in contact with each other and thereby to prevent waveguide mode excitation by a method wherein a metal block is fixed secure to a high frequency shield case by means of a flush head screw and the screw hole in the high frequency shield case is positioned as to be nearer to the inner wall wherewith the metal block is in contact. CONSTITUTION:A microwave circuit is constituted of signaol lines 2 arranged on one surface of a microstrip substrate 1 fixed secure to a metal case 4 together with a metal block 3 by means of a flush head screw 8 and round head screw 7. The case 4 and a metal cover 5 constitute a high-frequency shiel case. The inner diameter of a through-hole 31 is to be a little larger than the outer diameter of the portion not including the head of the flush head screw 8. A screw hole 41 is so eccentrically positioned that the distance (b), between the contact surface A whereat the metal block 3 meets the case 4 and the screw hole 41 for the flush head screw 8, is a little shorter than the distance (a) between the contact surface A and the through hole 31. Tightening of the flush head screw 8 causes the metal block 3 and the inner wall of the case 4 to contact each other under pressure. This in effect is equivalent to reduction in the inner width of the case 3, which contributes to the prevention of waveguide mode excitation.

Title: Selector valve device for construction machine
Inventor: MIYAOKA SATOSHI
IPC: F15B11/16
Filed: 1986-06-16
Abstract: PURPOSE:To enable the operating pattern of a construction machine to change in a short time and easily, by making it possible to change over a selector valve provided at the middle of oil passages between pilot valves and a directional control valve by means of the detent type slide of a spool. CONSTITUTION:A selector valve 28 is provided at the middle of oil passages between pilot valves 12a-12d, 13a-13d and a directional control valve 6. The operation of the detect type slide of a spool 27 enables the spool 27 of the said selector valve 28 to change over to each of plural different positions 'and'. Since the changing over operation of oil passage connections therefore requires no changeover of plural hose couplers and only the changeover of the selector valve 28, the operating pattern of a construction machine can be changed in a short time and easily without error.

Title: Floppy disk drive
Inventor: ODA SHINKO
IPC: G11B19/06
Filed: 1994-06-23
Abstract: PURPOSE:To reduce the size of the above device and to simplify a peak detecting means which outputs index pulse signals by using a single pole magnet as an index magnet to be mounted at a rotor. CONSTITUTION:The pole of the single pole magnet 2 is passed in proximity to a Hall element 5 by rotation of a rotor 1. This Hall element 5 is biased by biasing resistors 3, 4 and detects the magnetic flux of the single pole magnet 2. This magnetic flux is inputted through a differential amplifier 6 to a peak detecting circuit 7. The index pulse signal is then outputted from this peak detecting circuit 7. The Hall element 5 has dependency on temp. but the timing of the peak has no dependency on temp. and, therefore, the output of the good index pulse signal is possible. The peak detecting circuit 7 has a differentiation circuit 10 and a zero cross detecting circuit 9 which is inputted with the output of this differentiation circuit 10. The peak of the output from the Hall element 5 is detected by the approach of the single pole magnet 2 by detecting the zero cross of the output of the differentiation circuit 10 and, therefore, there is no dependency on temp.

Title: Shift lever device
Inventor: IMAI SATORU
IPC: F16H59/10
Filed: 1995-06-08
Abstract: PURPOSE: To provide a shift lever device which can ensure further safety and realize a shift lock condition surely under specific conditions even in a simple structure. CONSTITUTION: A shift lever device 10 is provided with a lock device 24 consisting of a cam 26 and a stopper 28.

For this reason, P range shift lock in which downward travel of the grooved pin 14 is limited is realized. Since shift lock is performed due to a simple structure which uses the cam 26 and the stopper 28, a mechanism of the shift lever device is simple, requires a small space, and realizes shift lock condition surely.
