Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To lessen consumption of an electrode rod by forming any one of layers of silicon carbide, titanium carbide, boron carbide, and tungsten carbide in a specified thickness on the surface of a rod-like body made of graphite. SOLUTION: An electrode rod is a rod-like body made of graphite and coated with a film of a carbide selected from silicon carbide, titanium carbide, boron carbide, and tungsten carbide with a thickness within a range from 0.5 to 2.0 mm. In a case the electrode rod 2 made of graphite and coated with the film of any carbide is used as a positive pole in a twin-torch type plasma ash melting furnace 1, no plasma arc is generated in the electrode rod 2 side in the positive pole side and electric current flows in the base metal 4 and the base metal 4 is put in heated and melted state by the Joule heat due to the electric current and ash is melted.  Since no plasma arc is generated in the electrode rod 2 on the positive electrode side and the temperature is not higher than the withstand temperature of the coating film, the consumption of the electrode rod 2 itself is suppressed to significantly low.

Title: Pattern forming method of charge coupled color line sensor
Inventor: HIRAMA MASAHIDE
IPC: H04N1/028
Filed: 1988-10-31
Abstract: PURPOSE:To prevent a pattern from being disordered in cyclic period by a method wherein the bits of a cyclic pattern are specified in numbers in the formation of a pattern of a charge coupled color line sensor whose pattern is formed through a divided exposure method. CONSTITUTION:As the number of bits of a cyclic pattern formed through divided exposure is a multiple of 12, even if there are cycles of a three-cyclic period such as (R, G, B), (Ye, Cy, G), or the like and a four-cyclic period such as (R, G, B, W), (Ye, Cy, G, W), or the like, the cyclic pattern, which is a multiple times as many as these cyclic units, is exposed to light in a lump through a divided exposure method. Therefore, the cyclic pattern is prevented from being disordered in cyclic period at the joint between the regions exposed to light in a divided manner. Through a divided exposure using a reduced projection exposure device, the pattern formation of even a large scale charge coupled color line sensor whose chip length is larger than 20mm can be protected from defects. The length of a color line sensor capable of being manufactured is restricted only by the diameter of a semiconductor wafer 6 to be employed.

Title: Core for deflecting yoke
Inventor: KOIZUMI YORIICHI
IPC: H01F3/08
Filed: 1989-10-23
Abstract: PURPOSE:To prevent the generation of cracks in a dividing trench forming part during baking, and facilitate the division from the dividing trench, by forming the dividing trench of a morning-glory type deflecting yoke, in a thick wall part whose thickness is larger than that of the peripheral part. CONSTITUTION:A core 1 for a deflecting yoke gradually increases its thickness from the peripheral part 12 toward a dividing trench 2 forms a thick wall part 11. Said thickness becomes equal to that of the peripheral part 12 at the dividing trench 2. When force is applied during baking, the force is dispersed in thick boundary parts 13, 14, and stress concentration to the dividing trench 2 is decreased. When stress is applied to the dividing trench 2, cracks are hard to be generated because the wall thickness is large as compared with conventional cores.

IPC: F16L59/04
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To suppress worsening of heat conductivity with the lapse of time by applying a plastic film formed of ethylene-vinyl alcohol copolymer resin with A1 evaporation applied to one side, to a gas barrier layer, and providing the Al evaporated face on the heat welded layer side. SOLUTION: Polyethylene terephthalate resin is used for an outermost layer, and an ethylene-vinyl alcohol copolymer resin with A1 evaporation applied is used for a gas barrier layer 5. An A1 evaporated layer is provided on the heat welded layer 6 side, and high density polyethylene resin is used for the heat welded layer 6.
