Title: Pressure control valve
Inventor: ONO MASAFUMI
IPC: F16K3/04
Filed: 1993-03-19
Abstract: PURPOSE:To attain a wide range of pressure control by mounting two semicircular valve bodies of a stationary blade and a moving blade inside a cylindrical valve easing so as to make the moving blade rotate as a rotating shaft coaxial to the central shaft of the valve easing. CONSTITUTION:A semi-circular stationary blade 7 is mounted inside a cylindrical valve easing 6, and the arc-shaped outer periphery edge of the stationary blade 7 is jointed to the inner wall of the valve easing 6. A semi-circular moving blade 8 is mounted so as to br rotated by a rotating shaft 9 coaxial to the central shaft of the valve casing 6. The moving blade 8 and the stationary blade 7 are mounted so as to form no clearance between them. When the moving blade 8 rotates, an open part (a) occurs between the moving blade 8 and the stationary blade 7. By controlling the rotational angle theta of the moving blade 8, the open part (a) of suitable size is generated to form proper piping resistance, so it is possible to attain precise pressure control over a wide range.

Title: Detection for internal defect of continuous casting slab in gas cutting
Inventor: YAMASHITA TOYOKI
IPC: G01N29/12
Filed: 1982-05-20
Abstract: PURPOSE:To detect internal defects of a continuous casting slab on a basis of a measured value obtained by measuring the oscillation of a blowpipe for gas cutting or sounds at a gas cutting time. CONSTITUTION:A blowpipe 2 is moved in the direction of an arrow 3, and the blow pipe 2 is always oscillated and generates a loud sound because oxygen for cutting is discharged from the blowpipe 2 in a high speed for the purpose of cutting a region B which is not cut yet. The jet of the cutting gas is affected by division of the center part into two, and internal defects are detected by the oscillation of the blowpipe 2 or the sound. Since internal defects are detected in the stage of gas cutting of the continuous casting slab, this method contributes the reduction of labor, and the continuous casting slab judged to be indefectible is sent directly to a heating furnace or a rolling mill. The degree of internal defects can be evaluated quantitatively.

Abstract: PURPOSE:To make a quite large cooperative area multiplicity through bags and fins by a method wherein non-continous and fine fins are formed longitudinally or angularly of the bags at either one of inner and outer surfaces of the bags or one of the inner and outer surfaces. CONSTITUTION:Saw-teeth are formed at inner and outer surfaces of a pipe having fins, the area of either one of the inner and outer fins of each of layers is enlarged by several multiplicity, the total thermal conducting area is made to have about ten times of a cylindrical surface equal to the outer diameter of an outer pipe 1 under an accumulative effect with an enlarged area of fins so as to improve performance and reduce cost. Longitudinal directions of fins F having saw-teeth therein may be in parallel with an axis of the pipe and a slight angle may be applied to the pipe. In any way, the length of these fins is made short, thereby an interface layer is prevented from being formed at the surfaces of the blades so as to improve the thermal conductivity. Means for forming saw-teeth is not varied more as compared with that of a file and so they may be strike cut with a blade, etc. In order to improve the efficiency of fins, the material is preferably aluminum, copper or copper alloy or titanium.

Title: Magnetic recording medium
Inventor: IKEGAYA MASAHITO
IPC: C09D175/04
Filed: 1989-04-05
Abstract: PURPOSE:To obtain the recording medium having the good durability of a magnetic layer by using a vinyl chloride resin having -SO3M (where M: alkali metal) and epoxy group as a binder component and oxyacid ester as a lubricant. CONSTITUTION:This magnetic recording medium is formed by applying the magnetic layer formed of magnetic metallic powder, binder and lubricant on a nonmagnetic base. The vinyl chloride resin having the -SO3M (where M: alkali metal) and the epoxy group in the molecular chain, for example, a polyurethane resin, is used as the binder for this magnetic metallic powder, by which the dispersibility of the magnetic metallic powder is improved and the self- decomposing property of the binder is lowered. Further, the oxyacid ester is used as the lubricant. Since this lubricant is smaller in the effect as the plasticizer of the magnetic layer as compared to the conventional lubricant composed of a fatty acid and fatty acid ester, the degradation in the strength of the coated film of the magnetic layer is lowered and the durability is improved.

Title: Hoist device for small elevator
Inventor: KONDO TAMAKAZU
IPC: B66B11/04
Filed: 1988-04-08
Abstract: PURPOSE:To enable the cost to be reduced of a standard hoist set up in no relation to a building shape by arranging a winding position of a main cable to a winding drum in the outside from a setup space of vibro-isolating members in a manner wherein they receive a compression load by tension of the main cable. CONSTITUTION:In the case of a hoist device for a small elevator, because a main cable 5 arranges its winding position to a winding drum 10 in the outside from a space of vibro-isolating rubbers 25, 27, they both receive a compression load by tension of the main cable 5. Accordingly, the vibro-isolating rubber 27 is not necessary to be fixed to a bottom part of a lift path 1 by foundation bolt or the like. While since a hoist 11 and machine beds 21, 22 are connected to a mounting beam 23, the main cable 5 supports its reaction force to a guide rail 2 through the mounting beam 23. Accordingly, eliminating the necessity for particularly reinforcing a building part for setting up the hoist 11 and/or performing work of the foundation bolt or the like, the following complicated trouble is eliminated. Further eliminating the necessity for providing a supporting bed, the lift path 1 can be formed in small depth.

IPC: B60T13/12
Filed: 1986-04-15
Abstract: PURPOSE:To provide the stroke jumping function for a power piston by dividing said piston into both the first part which is moved together with an output member and the second part which is engaged with a kinetically converting mechanism and carrying working liquid between the first part and the second part at the initial operating time to separate them from each other. CONSTITUTION:When a reaction piston 54 is moved forth, working liquid is forced into a power pressure chamber 34 and further advances into the clearance between both the inner piston 40 and the outer piston 38 of a power piston 32 to separate the opposing faces thereof from each other. Consequently, with the outer piston 38 and the reaction piston 54 standing still, the inner piston 40 moves forth by the relative movement allowance distance and subsequently, both the pistons 40 and 38 go forward together. By having the relative movement allowance distance set equal to the initial idling stroke, this initial idling stroke can be cancelled.
