IPC: B22D17/20
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent the fall-out even in the case of being a formed cold plug at a high temp., to secure the safety of a forming work and to improve the quality of a formed product by arranging the projections projected inward in a radius direction at the tip part of nozzle hole in an injection nozzle provided with a heater. SOLUTION: At the tip part of the nozzle hole 6 in the injection nozzle 5 provided with a heater 7 for adjusting the temp., the projections 8, 9 projected inward in the radius direction are provided. The shape, position and number, etc., of the projections 8, 9 are not specially limited, but it is desirable to form a continued annular projection 8 in the peripheral direction of the nozzle hole 6 or plural projections 9 in a specific interval in circular direction. These projections 8, 9 are served as the support of the cold plug cp at the high temp. remained in the nozzle hole 6 at the time of injection-forming and as the prevention of the fall-out caused by the carrying pressure at the time of weighting and the inner pressure, etc., during waiting the injection, but the projections having inclination shrinking the diameter toward the tip part of the projection are formed so as to easily extrude the cold plug cp at the time of succeedingly injecting.

Title: Separator for low temperature type fuel cell and manufacture thereof
Inventor: FUKUI YASUSHI
IPC: H01M8/02
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a metallic separator for low temperature type fuel cell, having superior acid resistance and conductivity while restricting the generated quantity of the Joule heat due to contact resistance. SOLUTION: This separator is obtained by forming a bonding layer 14 of carbonic grains on a base material 13 of stainless steel through a diffusion layer 16, and a surface of the bonding layer 14 is provided with a carbonic grain adhesive layer 15. The bonding layer 14 is formed by providing a coating film, in which carbonic grains are distributed on a base material surface, and thereafter, heating it at 300-950 deg.C in a non-oxidizing atmosphere. Prior to a heat treatment, the stainless steel base material 13 provided with the coating film may also be rolled.  Since a separator having a low contact resistance is obtained, the generation of the Joule heat as a heat loss is restricted even in the case where multiple cells are layered, and furthermore, carbonic grains of the adhesive layer 15 work as the lubricant, and this separator is formed into a required shape as a separator through pressing and blanking.

Inventor: ASANASHIYOSU KARIDASU
IPC: E21B43/22
Filed: 1988-12-06
Abstract: PURPOSE: To apply a steam mediated oil production increasing method to oil desposits of all types, to increase a recovery quantity, and to improve economical efficiency by using a steam injection recovery process for an oil deposit containing crude oil, etc., and making contact with a fluorochemical of a prescribed component. CONSTITUTION: A steam injection recovery process such as a circulating injection process or a steam driving process is applied to an oil deposit containing crude oil or a substance for generating crude oil.

Filed: 1990-11-16
Abstract: PURPOSE:To enhance a transistor characteristic by a method wherein a channel- part silicon layer whose surface-layer part is composed of amorphous silicon is irradiated with an oxygen plasma. CONSTITUTION:When a channel-part silicon film 107 is formed on an insulating substance 101 under a reduced pressure by using a chemical vapor deposition method (a CVD method), an amorphous silicon film 106 is deposited continuously on a channel-part silicon film 105 without breaking an inert or reducing low- pressure atmosphere after the channel-part silicon film 105 has been deposited. Then, before a gate insulating layer 110 is formed on an amorphous silicon film 108, the amorphous silicon film 108 is irradiated with an oxygen plasma 109. Amorphous silicon is oxidized; one part of the gate insulating layer 110 is formed at a low temperature; the interface between a semiconductor layer and an insulating layer is cleaned. Thereby, a transistor characteristic can be enhanced.
