Title: Wire type cutting device
Inventor: MASUYAMA SHOJI
IPC: B28D5/04
Filed: 1994-04-07
Abstract: PURPOSE:To eliminate breaking and release of a wire so as to improve cutting accuracy when an object to be cut is cut. CONSTITUTION:Three grooved rollers 3a, 3b, 3c are provided in parallel with the axial direction so that they come to vertices of a triangle. A wire 4 is wound around by overlapping it so that it engages with circumferential grooves 13 of the grooved rollers, fed from a supply reel 1, and wound up by a winding roll 2 to make the wire 4 run. A tensile force hold means 20 which holds tensile force of the wire 4 on both sides of the triangle at constant force is provided between the grooved rollers 3a and 3b and between the grooved rollers 3a and 3c. The tensile force hold means 20 consists of a tensile force providing member 9 which is in contact with the wire, a shaft 11 which supports the tensile force providing member, an elastic body 10 which presses the tensile force providing member with constant pressure, and a support member which supports the elastic body and the shaft 11. The wire 4 on a base between the grooved rollers 3b and 3c is used as a cutting section, and an object to be cut 5 is brought into contact with it to cut the object to be cut 5.

Title: Heat resistant electric wire and its manufacture
Inventor: SHISHIDO KANJI
IPC: H01B3/30
Filed: 1994-04-07
Abstract: PURPOSE:To provide a heat resistant electric wire displaying excellent heat resistance further having solderability, by providing a stabilization-processed insulating layer, mainly composed of polyacrylonitrile, on a conductor. CONSTITUTION:A heat resistant electric wire is provided with an insulating layer, mainly composed of polyacrylonitrile stabilizationprocessed in a structural formula, on a conductor. This insulated electric wire is obtained by applying an insulating coating, mainly composed of polyacrylonitrile, to the periphery of the conductor heated at 150 to 320 deg.C. Prescribing a lower limit of heating temperature of the polyacrylonitrile to 150 deg.C is caused by a reason that a temperature, at which the polyacrylonitrile can be made infusible in the atmosphere of oxygen or air, is 150 deg.C or more, and that at a temperature lower than 150 deg.C, the polyacrylonitrile is considered unstable with fusion difficult to be caused. Further, a reason for prescribing an upper limit of the heating temperature to 320 deg.C is that a fusing temperature of the polyacrylonitrile is about 320 deg.C, and in the case of suddenly heating beyond 320 deg.C, since a sufficient film can not be generated, a uniform insulating layer can not be formed by generating a pin hole.

Then the lubricant is washed with a solvent to remove unreacted carboxylic acid to form the lubricant layer 3 comprising a uniform, strong, chemical adsorption layer of fluorine-contg. carboxylic acid. Then a thin film of perfluoropolyether 4 is formed thereon, which gives excellent lubricating property and an effect of repairing the lubricant film to maintain high lubricating property. Thereby, the medium has improved still durability and traveling durability.

Title: Method of sandblasting with water
Inventor: OOTA SHIYOUZOU
IPC: B24C1/08
Filed: 1982-04-26
Abstract: PURPOSE:To heighten the effect of antirust treatment, by mixing a sandblasting material into pressurized water containing a low concentration of an antirust agent, to prepare sandblasting water and by using the sandblasting water to roughly treat a workpiece and thereafter using an antirust liquid of high concentration to finish the surface of the workpiece. CONSTITUTION:A sandblasting material supplied from a sandblasting material tank and high-pressure water supplied from a low-concentration antirust agent tank are mixed together to sandblast a structure from the bottom toward the top through a sandblasting nozzle. Before the sandblasted surface becomes dry, a finishing antirust liquid from a tank for a concentration not lower than about ten times of that of the liquid in the low-concentration antirust agent tank is projected onto the sandblasted surface. After that, the surface is dried and then painted. The liquid at the lower concentration of 50-1,000ppm is first applied to prevent the wet surface from rusting at the sandblasting. Right after that, th liquid at the higher concentration of 0.5-2.0wt% is applied to finish the surface. This results in heightening the effect of antirust treatment.

Abstract: PURPOSE:To obtain a high drawing resistance and a high frictional force by a method in which an expandible material is injected into a cylindrical anchor rod  whose peripheral wall is provided with ?-shaped and linear notches in such a  way as to erect and expand the notches. CONSTITUTION:The peripheral wall of a cylindrical anchor rod A is provided with ?-shaped notches 2 whose basal portions are turned toward the rear end of the rod A and linear notches 3 extending along the longitudinal direction of the rod A.

Filed: 1985-04-03
Abstract: PURPOSE:To obtain a projecting picture with a better picture quality without peeling of a transparent substance from the face plate of a video tube and a lens factor by using an elastic material as a frame body to hold the transparent substance having a large volume variation and performing the shape of a cross section at a contacting part with the transparent substance to a stairs-shape. CONSTITUTION:So that the shape of the cross section at the part where a frame body 22 is contacted with a transparent substance 25 is formed at a center part 26 in such a way that a straight line is bent at a right angle, the length measured along with the centering thick part of the center part 26 is longer than a space between end parts 23 and 24. Furthermore, so that the frame body 22 is constituted with the elastic material, the frame body 22 is easily transformed in the side direction even when the volume variation is occurred in the transparent substance 25 by a temperature change and an excessive inner stress is prevented to be occurred in the transparent substance 25. Therefore, the transparent substance 25 is able to stick continuously to a front glass plate 19 and a lens factor 21 with a few adhesive strength and a trouble such as the peeling of the transparent substance 25 when in using is prevented. Thus, the projecting picture with a superior contrast is always obtained.
