Title: Production of single mode fiber of constant polarized electromagnetic radiation
Inventor: OKAMURA KOJI
IPC: G02B6/00
Filed: 1985-04-27
Abstract: PURPOSE:To obtain the titled fiber having reduced transmission loss by an easy production method, by stopping rotation of a reaction tube while piling clad glass and core glass, heating one side of the reaction tube so that refractive index distribution at both the ends of fiber parent material is differed. CONSTITUTION:The material 2 is fed in the arrow direction to the reaction tube 1 consisting of quartz glass, etc., the raw material is heated while rotating the pipe 1 by the burner 5 so that a parent material for single mode fiber is piled on the inner wall of the tube 1 by CVD method. In a state where sufficiently thick clad glass is piled in the tube 1, the rotation of the tube 1 is stopped while core glass is being piled and the lower part of the pipe 1 is heated. Consequently the transparent glass film 3 is formed at the high-temperature part of the lower part, but the slightly non- transparent glass film 4 is made at the low-temperature part of the upper part which is not heated. Consequently, the low-temperature part at the upper part has higher concentration and higher refractive index and the high-temperature part at the lower part has a low refractive index. The tube 1 is turned upside down, heating and piling are carried out and the non-transparent part is made into glass. These operations are repeated several times, the feed of the raw material 2 is stopped and complete glass formation and collapsing are effected to give the titled fiber.

Title: Thermal head
Inventor: SATOU YOSHIHIKO
IPC: H01L49/00
Filed: 1984-05-09
Abstract: PURPOSE:To ensure a moderate length of a bonding wire while allowing the uniformization of print record density by making the pattern width of individual conductors in a narrow conductor width area broader for those arranged on the center side of an IC and narrower for those arranged on the end face side. CONSTITUTION:The pattern width of individual conductors is not the same at all but made broader gradually as approaching from a bonding terminal T1 or Tm to Tp or Tq so as to uniformize the conductor resistances of the individual conductors L1-Lm. So to speak, the conductor width is made broader in the longest individual conductors connected to the terminal Tp or Tq with a smaller conductor resistance while narrower in the shortest individual conductors connected to the terminal T1 or Tm with a higher conductor resistance. Thus, a conductor resistance correction area ''n'' minimum in the size is used to uniformize the conductor resistance.

Title: Formation method of aluminum-based pattern
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/302
Filed: 1992-04-13
Abstract: PURPOSE:To enhance the selectivity in a dry etching operation of an Al-based material layer. CONSTITUTION:An Al-based multilayer film 7 is etched by using a mixed gas of COCl2 (carbonyl chloride) and Cl2. A carbon-based polymer CClx formed as originated from the decomposition product of a resist mask 8 is endowed with a strong chemical bond and a strong electrostatic attraction force due to the introduction of a carbonyl group (>C=O); its etching-resistant property is enhanced. Consequently, it is possible to reduce the energy of impinging ions required for an anisotropic working operation and the decomposition amount of the carbonbased polymer; it is possible to enhance the selectivity of a resist and the selectivity of a substratum; in addition, it is possible to restrain a particle contamination and an aftercorrosion. When a mixed gas of COCl2 and S2Cl2 is used S (sulfur) is added to the constituent component of a sidewall protective film 9, and it is possible to realize higher selectivity, lower contamination, lower damage and higher aftercorrosion-resistantance of the title formation method.

Title: Manufacture of large body from powder particle in equilibrium state
Inventor: DEEBITSUDO GARESU MOORISU
IPC: C22C45/00
Filed: 1980-07-09
Abstract: A method of producing large objects from rapidly quenched non-equilibrium powders in which the powder is first slowly precompacted to a predetermined density without causing any substantial temperature rise. The powder is then rapidly compacted by a shock wave having a short rise time. In this way thin surface regions on the particles are rapidly brought to melting to cause interwelding of the particles. These thin surface regions are then rapidly quenched by conduction of heat to the interior of the particles. Because of the very rapid heating and quenching, in the order of a few microseconds, degradation of the material is avoided.

Abstract: PURPOSE:To reduce the lowering of yield of cold material and to further improve a heating efficiency of the material, by blowing oxidizing gas against the surface, intersecting the axial line of a converter, from injection nozzles installed in side holes which are provided to a tapping port or the converter-body. CONSTITUTION:Gaseous oxygen and fuel are blown into a packed layer of cold material 11 in a converter from bottom-blown tuyeres 9, through a bottom- blown oxygen feeding pipe 7 and a feeding pipe 8 of hydrocarbon series fuel, to start combustion just above the tuyeres 9. Combustion gas, which contains unburned gas such as CO and CH4 and rises through the cold material packed layer and flows toward a converter-port 19, is brought into contact with gaseous oxygen or air jet flow 21, jetted from injection nozzles 27 which are installed in side holes 23 provided to a tapping hole or the converter-wall, to be burned. As a result, a wide spreading combustion zone 14 of the unburned contents is formed in a plane shape which crosses the axial line 26 of the converter, and radiates the heat intensely to the surface of the packed cold material to improve the heating efficiency of the material. Further, the oxidation of the material and the generation of oxidized dust are perfectly avoided.
