Title: Vacuum arc descaling method
Inventor: KONDO JIRO
IPC: B08B7/00
Filed: 1994-02-28
Abstract: PURPOSE:To improve roughness after vacuum arc descaling by applying a liquid and/or a viscous material on the surface of a material to be treated in a method by which the surface of metal is treated by-discharging a vacuum arc on the material to be treated. CONSTITUTION:In the vacuum arc descaling treatment, the liquid 13 and/or the viscous material is applied on the surface of the material (metal) 10 to be treated, so the liquid 13 in the vicinity of an arc spot 14 is turned into a vapor and the arc is moved toward the vapor. Thus, the moving speed of the arc spot 14 is increased. That is, the arc discharge in a vacuum is different from the discharge in the air, a lot of arc columns are generated between the cathode and the anode 11, the arc columns are turned into cathode points (arc spots) 14 on the surface of the material 10 to be treated and the arc spots move about in search of scale 12. Then, when the moving speed of the arc spot 14 is increased, the arc spot can not locally stay at the cathode, so local excess melting is not caused and surface roughness is improved.

Abstract: PURPOSE:To obtain constant composition, and prevent exfoliating from a polycrystalline silicon film of lower layer due to heat treatment in the later processing, by protecting a silicide film as an upper layer of polyside structure with a polycrystalline silicon film or an amorphous silicon film. CONSTITUTION:After a gate oxide film 2 is formed on a silicon substrate 1, and a polycrystalline silicon film 3 is stuck thereon, phosphorus as impurity is added. A tungusten silicide film 4 as a high melting point metal silicide film 4 is stuck, and further a polycrystalline film 5 is stuck thereon. By patterning, a gate electrode part is formed. A polycrystalline silicon film 3' and a tungsten silicide film 4' constitute a polyside structure, and a polycrystalline silicon film 5' is stuck thereon, which forms a protecting film. After a silicon oxide film 6 is deposited by vapor growth, an oxide film side wall 6' is left only on the side surface of a gate electrode, and the other parts are eliminated by anisotropic etching. Thus a specified gate electrode is formed. As to the protecting film, an amorphous silicon film has the same effect.

Title: Ultrasonic welding method
Inventor: SHINONAGA HIDEYUKI
IPC: B23K20/10
Filed: 1981-03-05
Abstract: PURPOSE:To improve joining capacity between materials in ultrasonic welding by applying an electric current between materials to be joined, and generating heat due to resistance. CONSTITUTION:Materials 7, 8 to be joined are held between the tip 4 to which ultrasonic oscillation is given and the anvil 6 of a fixed stand. An electric current is supplied between these materials 7 and 8 to be joined from a power source 10 through an electric wire 11 to generate heat by resistance in the materials 7 and 8. Arrival at temperature suitable for welding is facilitated by rise of temperature caused by heat generated by resistance even when the amount of generation of frictional heat caused by ultrasonic oscillation is small. The place where current flows is limited between the mateials 7 and 8 to be joined, and temperature rise due to flow of current in the tip 4 and anvil 6 is eliminated. By this way, materials so far difficult to make ultrasonic welding become easy to weld.

Abstract: PURPOSE:To automatically stop a nuclear reactor when a reactor temperature increases abnormally by melting electric fuses by the lowering of inductance of a temperature sensing coil due to a Curie point effect to demagnetize an electromagnet. CONSTITUTION:The iron core of a temperature sensing coil 36 is formed of magnetism material having a Curie point at proper temperature and coolant is directly put into contact with the outside thereof. When the coolant temperature of the outlet of a reactor core increases abnormally, the temperature of the iron core of the temperature sensing coil 36 increases immediately and the inductance of the temperature sensing coil 36 is abruptly reduced because magnetic permeability is abruptly lowered in the neighborhood of the Curie point. Thus, current increases abruptly, electric fuses 43 are melted, exciting current of an electromagnet 12 is shut down and control rods scram to perform reactor stop.
