Title: Gate valve
Inventor: JIYON BIIZON
IPC: F16K3/20
Filed: 1991-01-30
Abstract: PURPOSE: To flow a fluid to a valve chamber side through a seal part without damaging an elastic seal member by providing a releasable actuating device reducing contact pressure of a secondary seal loaded on a gate by a secondary seal assembly. CONSTITUTION: A secondary seal assembly structure can relieve contact pressure of a secondary seal at the time of opening and closing of a gate 15, and the pressure relief device is provided with a spring member 40 arranged between a seal support ring 31 and a space ring 38. The spring member 40 is allowed to have a spring constant selected in consideration of fluid pressure, so that when a seal retaining body 36 is pressurized and contacted on the gate 15 to form the secondary seal, a suitable contact pressure is continually kept between the seal retaining body 36 and the gate 15.  However, when pressure more than a prescribed degree is applied on the seal retaining body 36 by the fluid pressure of an upper stream side (a flow path 26 side), the spring member 40 is compressed, and if largely compressed, the seal retaining body 36 is separated from the gate 15 to prevent the breakdown of an elastic seal member 36a.

Title: Isolator for high power
Inventor: MOTOHASHI YASUO
IPC: H01P1/39
Filed: 1994-05-13
Abstract: PURPOSE:To form an isolator for high power with high power resistance and improved heat radiation property. CONSTITUTION:A dielectric 5 is provided between the opposing surfaces 13 of a pair of ferrite 2 provided inside this isolator 1. The dielectric 5 is in contact with the respective opposing surfaces of the ferrite, covers peripheral edges 14 and is attached. Further, for the ferrite, metal is vapor deposited to joined surfaces with a case body 3 and the vapor deposition surfaces 6 are stuck by molten metal such as solder or the like. Thus, since the peripheral edges of the opposing surfaces of the ferrite are covered with the dielectric, microwave discharging is not generated in the opposing surfaces and the peripheral edges. Also, since the dielectric is extended near the case body 3, the heat radiation property is improved as well since heat around the opposing surfaces is transmitted through the dielectric and the heat around the case body is transmitted through the metal for adhesion.
