Title: Phase control method for reducing amplitude peak of frequency multiplexing signal, and signal transmitter
Inventor: KURAKAKE TAKUYA
IPC: H04N21/2365
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To keep phase point arrangement for max. amplitude regardlessly of the variation in the frequency of a reference signal and to stabilize max. amplitude reduction by using a phase shifter capable of varying a phase by means of the voltage of the output of a phase comparator. SOLUTION: The output of a first frequency converter 3-(1) and the output of the second frequency converter 3-(2) are introduced to the first phase phase comparator 4-(1) and the output of the first comparator 4-(1) is fed-back to a first variable phase shifter 2-(1). Then, the phase of the output signal of the first variable phase shifter 2-(1) is controlled so as to permit phase difference between the two input signals of the first phase comparator 4-(1) to be π/(N-1). Thus, the phase difference between the difference frequency signals of an adjacent VSB and AM modulator is arranged in accordance with the declination of a phase point which divides circumference into N-1 on a basis of the phases of the difference frequency signals of the first VSB and AM modulator 1-(1) and the second VSB and AM modulator 1-(2).

IPC: H01L29/786
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To form a gate insulating film and an interlayer insulating film of high moisture absorption resistance on a substrate at a low temperature by a method wherein a channel semiconductor layer is formed of an Si-based semiconductor, a gate insulating film is formed of SiO2 and a gate insulating film which contains much silicon is formed on a surface layer on the opposite side of the substrate. SOLUTION: An amorphous Si film is formed on a substrate 1 at a substrate temperature of about 450 deg.C, it is annealed at a substrate temperature of 400 deg.C so as to be changed into a poly-Si film, the film is etched to be a desired shape as an island, so that a semiconductor layer 2 is formed. An SiO2 film 3 to be used as a gate insulating film is formed on it at a substrate temperature of 300 deg.C. A hydrogen plasma treatment is executed to the surface layer of the gate insulating film 3 (at a substrate temperature of 300 deg.C), and an oxide film 4 which contains much Si is formed. Since the oxide film hardly permeates moisture, the moisture absorption resistance of the gate insulating film is increased.  In addition, since the hydrogen plasma treatment is a low-temperature treatment, the gate insulating film and an interlayer insulating film of high moisture absorption resistance can be formed on the substrate at a low temperature.

Abstract: PURPOSE: To enable the safe and simple molding, carrying, preheating and charging into a smelting furnace by placing the basket of the special construction on a pressing base having a protrusion on the bottom, inserting iron scraps therein and compression-molding these to the specified bulk density.  
     CONSTITUTION: A protruding part 1' is formed at the bottom center of a conical pressing base 1 and a supporting arm 2 is provided thereon at the bottom. A basket 3 of cylindrical body inserted with heat-insulating refractories 3' is then placed thereon. Iron scraps are packed in the basket 3 and are pressure-molded by a push die 10 so that the bulk density of the molded lump becomes 1.1W1.3. Thence, the basket body suspension handles 9 are hoisted by a crane or the like and the basket is carried into a preheating chamber, where it is capped and is preheated. Since this iron scrap lump has a concave hole at its central part, the preheating effect is good. Thence, it is carried into an electric arc furnace or the like, where the supporting arm 2 is opened to lower the iron scrap lump. When the basket 3 is pulled up, the iron lump is charged into the furnace. This molded lump dissolves efficiently in the smelting furnace.

Title: Electrode for cylindrical battery and its manufacture
Inventor: KURASAKO KAZUHIRO
IPC: H01M4/30
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To wind a cylindrical electrode in a spiral shape easily and reduce a remaining space at a begining end and an end of a winding by making both longitudinal end parts of the cylindrical electrode, in which active material is filled in holes of band type porous metal with a skeleton having three dimensional net work structure, thin in thickness and soft in comparison with a center part. SOLUTION: When an electrode is wound in a spiral shape, a beginning part of a winding has excellent bendability since it is thin and soft, and a diameter of the beginning of the winding can be made small. Thereby, a space which has nothing to do with electric capacity produced between the beginning and the end of the winding can be made small, so that a battery with a high capacity can be made by increasing a filling volume of an electrode group to a case only in a part where a remaining space is reduced. Also, the remaining space mentioned above can be smaller by shaping both longitudinal end parts of the electrode so that they become gradually thin as it goes toward their tips from roots.

Abstract: PURPOSE:To recover easily in good efficiency a Lewis acid used as a catalyst in a process for copolymerizing an unsaturated hydrocarbon with a heteroatom- containing unsaturated hydrocarbon by forming a complex in this polymerization system. CONSTITUTION:A process for recovering a Lewis acid from the polymerization system obtained by copolymerizing an unsaturated hydrocarbon with a heteroatom-containing unsaturated hydrocarbon in the presence of a Lewis acid represented by the formula: MXn (wherein M is a metal atom selected from among groups IB-VB and VIII of the periodic table; X is halogen; (n) is the valance of the metal; and when (n) is 2 or greater, X groups are halogen atoms of different kinds), wherein the heteroatom-containing unsaturated hydrocarbon is added to the polymerization system in the absence of the unsaturated hydrocarbon to form a complex of the heteroatom-containing hydrocarbon with the Lewis acid. As the Lewis acid, other Lewis acids than MXn, e.g. aluminum compounds, zinc compounds and magnesium compounds having metal- carbon bonds, cannot be used because they cause polymerization with the heteroatom-containing unsaturated compounds in the course of recovering the Lewis acids.
