IPC: F16K17/04
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent the water pressure of a conduit down stream of a non-return device from becoming high-pressure when the water supply is stopped. SOLUTION: A non-return device 17 is disposed in a water supply passage of a combustion equipment. This non-return device is provided with a fluid passage 48 for allowing water pass therethrough from an inlet opening 46 to an outlet opening 47. A backflow prevention valve seat 50 and a non-return valve disk 51 are disposed in the inside of a flow passage 48 so as to prevent the backflow from the outlet opening 47 side to the inlet opening 46 side. A communication passage 61 which makes the flow passage 48 disposed at the inlet opening side than the valve disk 51 and the flow passage 48 disposed at the outlet opening side than the valve disk 51 communicating with each other is formed in the inside of the backflow prevention valve body 51. A valve seat 63 and a valve body 64 are formed in the communication passage 61.  In the condition that the backflow prevention valve seat 50 is closed, when the water pressure of the outlet opening side become higher than the pressure of the inlet opening side by not less than a predetermined difference, the valve disk 64 is removed from the valve seal 63 so that water passes through the communication passage 61 thus releasing the excessive water pressure of the outlet opening side to the inlet opening side. Since the excessive water pressure of the outlet opening side can be released, the water pressure of the outlet opening side is prevented from becoming high-pressure.

Title: Semiconductor device and its manufacture
Inventor: NAKAJIMA TAKASHI
IPC: H01L29/78
Filed: 1993-12-24
Abstract: PURPOSE:To prevent the occurrence of such defects as the deterioration of electric characteristics, delamination, cracking, etc., which are caused by stresses in a semiconductor device by crystallizing an amorphous layer deposited at a time by limiting its thickness to a value stipulated by the critical stress value or lower and piling up the stress-reduced polycrystalline layer. CONSTITUTION:On the surface of a p-type silicon semiconductor substrate 4 formed on a silicon oxide film 5, divided amorphous silicon layers 13 are formed so that the thickness of the layer 13 formed at a time can become the value stipulated by the critical stress value which is decided by a defective phenomenon. When the temperature of the substrate 4 is maintained at >=600 deg.C, the amorphous silicon is crystallized and divided polycrystalline silicon layers are formed. Therefore, the stresses generated in the layers 6 can be suppressed to the critical stress value or lower. This process is repeated until the total thickness of the layers 6 reaches a required thickness. As a result, a laminated layer 14 of divided polycrystalline silicon layers having a stress-reduced structure is formed.
