IPC: F16K7/16
Filed: 1993-09-02
Abstract: PURPOSE:To stabilize a flow characteristic and improve durability by forming a pressing member made of metal, and providing a resin made soft cushion member, that is, a resin coating layer in a lower surface of this pressing member, relating to a contact part of the fellow metals such as a metal diaphragm and a valve seat. CONSTITUTION:When a metal diaphragm 5 is pressed through a pressing member 12 by lowering down a valve rod 8, the metal diaphragm 5, elastically deforming downward the central part into a protrusively curved shaped, is brought into press contact with a valve seat 4 and placed in a valve closing condition. In a metal diaphragm valve thus obtained, the pressing member 12 is made of copper alloy, to form its upper surface into a flat surface brought into contact with the valve rod 8 and the lower surface into a curved surface of large radius of curvature of the metal diaphragm 5. A PTFE coating layer is provided in the curved surface serving as a contact surface with this pressing member 12. Thickness of this coating layer is set to 20% or more a total thickness of the metal diaphragm. Thus by preventing an indentation or the like from being easily generated in the metal diaphragm 5, durability is improved.

Title: Squid magnetometer
Inventor: KOBAYASHI HIDE
IPC: G01R33/035
Filed: 1987-08-31
Abstract: PURPOSE:To measure fine variation of earth magnetism even if an aircraft changes its direction by rotating a squid sensor so that one of detection direction among an X-axial, a Y-axial, and a Z-axial direction meets the direction of the earth magnetism at all times. CONSTITUTION:When the aircraft which mounts the squid magnetometer navigates while the direction of the earth magnetism does not match with the Z axis, the earth magnetism detected by a squid sensor 10 has finite values as its X-axial and Y-axial components and servo motors 32a and 32b rotate. Consequently, the squid sensor 10 rotates in such a direction that the direction of the earth magnetism meet the direction of the Z axis. Thus, a mechanism which supports the squid sensor 10 rotatably so that the direction of the earth magnetism meet the direction of the Z axis is controlled to detect fine variation in the intensity of the earth magnetism even if the navigating direction of the aircraft, etc., changes slowly.
