Title: Gas relief valve
Inventor: SAKU ICHIROU
IPC: F16K24/04
Filed: 1979-02-28
Abstract: PURPOSE: To conduct gas discharge smoothly by a method wherein a valve body and a float are coupled together, with a variable distance there between, and the floating of the valve body during initial gas discharge is restrained by the weight of the float.  
     CONSTITUTION: The vertical movement of a float 6 relative to a valve body 5 is restricted by the contact of screw members 15 with the upper and lower surfaces of an engagement hole 13. When a large amount of gas is purged upon start of flowing of a liquid, the valve body 5 is floated within a restricted range, before applied with the weight of the float 6. During continuous flowing of the liquid, as the float 6 ascends due to its own buoyancy, the valve body 5 closes a vent hole 7, the float 6 comes close to the valve body 5, and then parts from the valve body 5 within a restricted range while closing a small vent hole 11. Thus, gas discharge through the hole 11 is conducted smoothly.

CONSTITUTION:A field insulating film 2, a p-type channel stopper region 3, an n+ type semiconductor region 5 which is one of electrodes of a capacitor, a dielectric film 6 of the capacitor and an insulating film 7 are formed on the surface of a p-type semiconductor substrate 1. then, a polycrystalline silicon film 10a is formed on a gate insulating film 9, n-type impurities are introduced by performing a thermal diffusion and an ion implantation. Subsequently, a W-silicide film 10b is formed on the whole upper surface of the polycrystalline silicon film 10a, and a resist mask 11 is formed thereon. Then, the film 10b is patterned by performing an etching using the gas is which O2 is added to CCl4 gas, for example, and then a fate electrode 10 is formed by performing a patterning on the lower layer. As the rate of selectivity between the film 10a and 10b, and the insulating film 9 consisting of a silicon oxide film 9 is 10 or thereabout, the surface of the substrate 1 is not exposed by the etching gas. Then, the side face of the films 10a and 10b is etched by performing an isotropic dry-etching using SF gas and the like, for example. As the ratio of selectivity between the films 10a and 10b, and the insulating film 9 is large, which is 100 or thereabout, the surface of the substrate 1 is not exposed.
