Title: Molding of wire net and apparatus therefor
Inventor: SATOU TAKAYUKI
IPC: B21D26/02
Filed: 1977-11-25
Abstract: PURPOSE: Compressed gas is passed through a wire net to exert uniform pressure thereon effecting molding of curved wire net without causing net soil or clogging.  
     CONSTITUTION: A controller 28 is actuated to flow a high pressure gas from a gas clyinder 11 through pipe into a molding chamber 18 to fill it with a stationary atomosphere. Then, the controller 28 sends a signal to close valves 21 and 20, operate a pump 15 sending the high pressure gas into an electric furnace 16, where the gas is heated and returned to the molding chamber 18. The heated gas circulates through a wire net in the chamber 18, anescape pipe 19, an outlet pipe 13, the pump 15 and to the chamber 18. In the molding chamber 18, the wire net is deformed by the fluid pressure of high temperature, high pressure gas until a desired hemispherical shape is provided. The deformation process is monitored by a plurality of sensors and when the shape is completed, the sensors send a signal to the controller 28 to stop the operation.

Title: Improved selective cvd adapted to production process of semiconductive device
Inventor: HIRASE IKUO
IPC: C23C16/08
Filed: 1988-06-08
Abstract: PURPOSE: To improve the selectivity of CVD and the contact characteristics of formed films by subjecting a semiconductor wafer to a dry etching treatment by using an NF 3 -contg. gas in a stage for forming a high melting material film by the selective CVD on the wafer.  
     CONSTITUTION: In the SiO 2  film 2 on the surface of the Si substrate 1, contact holes 3 are bored. This wafer 10 is placed on a hot plate 7 in a reaction vessel 9 where the wafer 10 is heated. A metallic source, such as WF 6 , and a reducing agent, such as H 2 , are then introduced into the vessel and the high melting films, such as W films 4, are formed in the holes 3 by the selective CVD. The NF 3 -contg. gases are introduced into the vessel during the course of the reaction or after the end of the reaction and a dry etching treatment is executed to remove the natural oxide films covering the ground surface of the wafer 10. As a result, the W particles hardly adhere to the surface of the SiO 2  films 2 and the sufficient CVD is executed.

Title: Surface-worked metallic luster thin film
Inventor: HAYASHI YOSHIO
IPC: G11B7/24062
Filed: 1990-06-01
Abstract: PURPOSE:To reduce the production price of the metallic luster thin film and to attain accurate surface working based upon a massproduction effect by ruggedly forming the surface of a highly reflective metallic luster thin film formed by dispersing metallic particles into a hydrophobic binder in the 50nm to 5mm depth direction and width direction. CONSTITUTION:The high reflective metallic luster thin film formed by distributing metallic particles into the hydrophobic binder is formed as a surface- smoothed reflective layer prepared for the succeeding process prior to rugged surface working. Namely, the surface-smoothed reflective layer is formed by forming a layer consisting of an organic metallic oxidant, a reducing agent and hydrophobic binder on a base film by application or the like and then heating the layer. When a metal nobler than the metallic sort of the metallic oxidant is extremely finely stuck to the surface of the coating layer and heated prior to the heating processing, the noble metal sort acts as a catalyst core, reaction between the metallic oxidant and the reducing agent is accelerated in the vicinity of the catalyst and the highly reflective metallic particle distributing layer is formed in the vicinity of the surface of the application layer.
