Title: Water-repelling agent for fiber
Inventor: ONO ICHIROU
IPC: C08F290/06
Filed: 1994-06-24
Abstract: PURPOSE:To produce a water-repelling agent capable of applying water repellency excellent in durability to a fiber by conducting a radical polymerization of a specified organopolysiloxane and another monomer radical-copolymerizable therewith. CONSTITUTION:Application of water repellency excellent in durability is readily carried out by synthesizing a copolymer through a radical polymerization of an organopolysiloxane compound having one radical-polymerizable group in one molecule and represented by the formula [R<1> is H or methyl; R<2> is a 1 to 12C divalent hydrocarbon which may be rntercepted by O; R<3> is methyl or trimethylsiloxy; R<4> is a 1 to 4C univalent hydrocarbon; (n) is 3 to 200; (m) is 1 to 3] and radical-polymerizable monomers composed mainly of an acrylate and/or a methacrylate preferably according to the solution polymerization method, dissolving the obtained copolymer in an alcohol and immersing a natural or synthetic fiber in the resultant solution. Since this water-repelling agent is dissolved in a nontoxic alcohol such as ethanol or isopropanol, it is suitably used in the form of an aerosol by using a propellant gas.

Title: Manufacture of ultralow si free-cutting steel
Inventor: HATA TAKAMIKI
IPC: C21C7/00
Filed: 1979-12-20
Abstract: PURPOSE: To manufacture an ultralow Si free-cutting steel with superior machinability and cold workability by adjusting the lining refractory of a molten steel vessel used in a low Si free-cutting steel refining process to a composition free from SiO 2  simple crystals.  
     CONSTITUTION: When molten steel is discharged into a vessel such as a ladle or a tundish in the refining of a low Si free-cutting steel contg. <0.005% Si, SiO 2  in the lining refractory of the vessel is reduced to Si to often increase the Si content of the molten steel. In order to prevent the reduction, SiO 2  in the refractory is allowed to exist in the form of an eutectic compound of SiO 2  and other basic or neutral oxide in place of SiO 2  simple crystals. Accordingly, the SiO 2  content of the refractory is adjusted to ≤30%, ≤50%, ≤60%, ≤30% ≤50% and ≤30% in case of Al 2 O 3 -SiO 2 , CaO-SiO 2 , MgO-SiO 2  CaO-Al 2 O 3 -SiO 2 , CaO-MgO-SiO 2 , and MgO- -Al 2 O 3 -SiO 2  respectively. Thus, an increase of Si from the lining refractory by reduction is prevented, and a free-cutting steel contg. ≤0.005% Si can be manufactured.

Title: Production of precise metal disk
Inventor: YAMAZAKI ATSUSHI
IPC: B21J5/02
Filed: 1987-07-06
Abstract: PURPOSE:To improve the dimensional accuracy of a metal disk by constraining the mean coating amt. of a lubricant for a disk like metal material less than a specified value per unit area and further limiting the variance thereof <=a specified %. CONSTITUTION:In the case of coining a precise metal disk, the mean coating amt. of a lubricant coating on a disk like metal material is constrained <=100mg per 1m<2>. The variance (max. coating amt.-min. coating amt.) in the amount of a lubricant in the region to be coated is limited by holding it at <=20% of the mean coating amt. Thus, the coating state of the lubricant is equalized and the metal flow in the radial direction by the coating method is uniformized. Consequently the dimensional accuracy of a precise metal disk is improved.

Abstract: PROBLEM TO BE SOLVED: To clean the inside of a measuring cell surely and easily by composing the inner surface of a measuring cell of a tubular optical glass and wiping the inner surface of glass in the circumferential direction by means of a wiper. SOLUTION: The inner surface of a measuring cell 1 is composed of a tubular optical glass 11 and an measuring optical path 10 is set in the diametrical direction substantially at the central position of tube.

Title: Clock signal distribution circuit and its method
Inventor: MIURA KATSUHIRO
IPC: H01L21/822
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To reduce the skew of clock signal between circuit blocks with no complex timing adjustment where delay between circuit blocks is adjusted by providing a clock signal which is a base of an integrated circuit directly to a gated clock signal generating circuit. SOLUTION: At a time T1, a base clock signal CK is inputted into buffers 21 and 23 and a gated clock signal generating circuit 24. At a time T2 which is delayed from the time T1 by ΔTK, gated clock signals CK1 and CK2 are generated, and further a gated clock signal CK2G is generated at the time T2, which is supplied to a circuit block 32. Since a delay time ΔTK of the clock signal CK1 or CK2 against the base clock signal CK is almost equal to the delay time of the gated clock signal CK2G against the clock signal CK, a skew between the clock signal CK1 or CK2 and CK2G is reduced.
