Title: Odd/even number field discriminating device
Inventor: FUTAGAMI AKIRA
IPC: H04N5/10
Filed: 1986-11-13
Abstract: PURPOSE:To attain quick discrimination without a malfunction by obtaining a pulse base having a different width from other part at a prescribed interval in the vicinity of the front and tail edges of a vertical synchronizing signal from a circuit triggered by each composite synchronizing signal pulse and generating a pulse train to which pulse width is between H/2 and 1H and detecting the width and interval. CONSTITUTION:In the transition from an even number field to an odd number field, a counter 16E counts the output of a monostable multivibrator MMV 13 inverted by an inverter 15 at a 3rd vertical synchronizing pulse period, that is, one clock. Then the counter is reset by the output B of a vertical period separation circuit 11 at a 4th vertical synchronizing pulse period, continues the counts of clocks after a 5th vertical synchronizing pulse period, count a 5th clock at a 10th line period and outputs a pulse F to open an AND gate 19. On the other hand, the output D of the MMV 14 goes to L0 during the 10th line period while the output C of the MMV 13 is at 3H/4, time L0 and the output D becomes an odd number field discrimination output via an inverter 17 and a gate 19.

Filed: 1994-11-04
Abstract: PURPOSE: To reduce the total contamination level of a base material or an article by removing embedded contaminant adjoining the surface layer from the base material of porous nature, and collecting the removed layers safely and disposing of them. CONSTITUTION: A contaminated concrete base material 10 includes a surface layer 12 which contains contaminants. The surface is scanned in the whole area with a laser beam 14 on the raster system. The concrete facial layer 12 is evaporated by the laser beam 14, and contaminated fumes are gathered by an appropriate extraction device 16. After passage of the laser beam 14, a surface course 18 turned in glass partially remains. In this manner, embedded contaminant is removed, and the removed layers are collected safely and disposed of, and thereby the total contamination level of the base material or any article can be reduced.

Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To increase the thickness of the outer skin layer of a metal honeycomb structure in which the outer skin layer is integratedly joined to a core part in which a passage is formed by a thin wall. SOLUTION: A batch material of plasticized metal powder is passed through a die 14 and an annular mask 12 and is extruded. A thin wall is formed of a slot 20 opening to the main outlet part of an outlet face. The mask 12 has a mask surface 12b extruding a honeycomb core and a blocking surface 12a blocking the slot 20. The batch material discharged from the slot 20 near the clogging surface 12a is discharged to both of an annular reservoir 40 and a skinforming gap 38 between the outlet face and the mask 12. The batch material accumulated in the reservoir passes through a reservoir gap between the ambient part of the outlet face and the mask 12 and is discharged to the skinforming gap 38. This discharged batch material is integrated with the batch material directly discharged to the skinforming gap 38 to form a thick outer skin layer.

Title: Anti-bending and anti-vibration flexible conductor
Inventor: SHIMIZU SAJIRO
IPC: H01B5/08
Filed: 1988-10-26
Abstract: PURPOSE:To prevent a wire cutting owing to abrasion and to improve the durability by using a pure soft copper wire for the elemental wire of a basic strand which composes the outermost layer, and a softened wire of a specific copper alloy for the elemental wire of a basic strand in the lower layer contacting the basic strand of the outermost layer. CONSTITUTION:A compound strand wire 2 made by stranding collecting strand wires 1 concentrically is used as a basic strand wire, and such basic strand wires are further stranded concentrically to make a doublecompound strand to be used as the flexible conductor. The elemental wire of the basic strand to compose the outermost layer of the doublecompound strand is made of a pure soft copper wire. In this case, a softened wire of a copper alloy which consists of 0.1 to 1.5wt.% of Ti, 0.2 to 2.0wt.% of Sn, 0.5 to 1.0wt.% of Zn, and the remaining wt.% of copper is used as the elemental wire of the lower layer basic strand contacting the basic strand of the outermost layer. As a result, at the contact parts between the basic strand of the outermost layer and that of the lower layer where an abrasion wire cutting of the elemental wires is generated remarkably, the contact is made between different sorts of metallic wires. Consequently, the coefficient of friction is reduced compared to the case of contact between the same metallic wires, and the anti-abrasion property is improved. The abrasive wire cutting is hardly generated accordingly.

Title: Poultice for mucous membrane of oral cavity
Inventor: KISHI TAKASHI
IPC: A61L15/16
Filed: 1987-10-26
Abstract: PURPOSE:To stick a poultice over a long time without imparting a feeling of physical disorder, by forming a protective layer based on a specific acrylate copolymer and a softening agent and having a specific thickness to the single surface of a sticking agent having stickiness to the wet surface of a mucous membrane. CONSTITUTION:A poultice for the mucous membrane of the oral cavity is constituted by forming a protective layer to the single surface of a sticking layer having stickiness to the wet surface of the mucous membrane. The protective layer is formed from an acrylate type (co)polymer containing alkyl (meth)acrylate as a (co)polymer component in a ratio of 40wt.% or more and a softening agent capable of softening said (co)polymer. This acrylate type (co)polymer is soluble in an alcoholic solvent and insoluble in water, and the softening agent has an ester bond and/or ether bond in the molecule thereof. The thickness of the protective layer is set to 1/10 or less that of the sticking layer. The sticking agent used in the sticking layer is based on a water-soluble high-molecular compound, a water-retentive softening agent and a hydrophylic high-molecular compound or a hydrophobic rubbery substance. This sticking agent imparts no feeling of physical disorder when this poultice is stuck to the surface of the mucous membrane of the oral cavity for a long time and has no toxity to a human body.
