摘要： PURPOSE:To obtain a torsional damper of low cost, easy to produce, outstanding in high-temperature bond strength, durability, etc., by pressing a preliminarily compressed elastomeric member into between inner and outer cylindrical members followed by integrally bonding them using a specific adhesive. CONSTITUTION:An elastomeric member to be pressed into between (A) a rigid inner cylindrical member to be fitted on a revolving shaft and (B) a rigid outer cylindrical member as the damper mass to be concentrically located against the member A is, in advance, cured and molded into a band-shaped or cylindrical form. Thence, an adhesive consisting mainly of chlorosulfonated polyethylene is coated on the respective surfaces of the outer circumference of the member A and inner circumference of the member B and/or the both surfaces of said elastomeric member followed by coating the adhesive-applied surfaces with a lubricant oil compatible with said elastomeric member. This elastomeric member is then pressed into between the members A and B in a specified compression rate to effect bonding into a unit, thus obtaining the objective torsional damper.

摘要： PURPOSE:To obtain sufficient strength, while the position of a meld line is shifted from the position where maximum stress occurs by a method in which the mold composed of a rod molding cavity, a first cylindrical part molding cavity and a second cylindrical part molding cavity, is used, and resin is poured thereinto from the side wall of the first cylindrical part molding cavity positioned on the side of the cross section with large area. CONSTITUTION:When prescribed resin material is poured into a molding cavity from the gate A on the side part 24 in a first cylindrical part 14, the first molding cavity 40 is filled with said resin, while the resin flows separately to both sides in the peripheral direction of the molding cavity 40 of the first cylindrical part, thereby molding the first cylindrical part 14. On one hand, a rod molding cavity 38 and a second cylindrical part molding cavity 42 are filled with said resin, and a rod 12 and a second cylindrical part 16 are molded, whereby its weld line occurs on the Y-Y line having the small degree of stress. Consequently, the design strength of resin original in the obtained connecting rod is effectively provided.

摘要： PURPOSE:To secure a noise preventive effect, by attaching a noise insulating rubber sheet of a specific component and exceptional specific gravity to at least one surface of a cover body consisting of a metal plate, in case of a cylinder cover for a V-type, 6-cylinder engine. CONSTITUTION:In a cover body 15, its sectional form is subjected to press plate working into almost U-shaped form so as to meet an outer diametral form of a cylinder head side. A noise insulating rubber sheet 16 of about 6.5 in specific gravity, setting chlorine polyethylene down to parent rubber and made up of containing lead oxide powder is solidly vulcanized and stuck to a surface facing to the cylinder head side and another surface at the opposite side almost across-the-board. Thus, a noise preventive effect comes to fruition, therefore cost comes inexpensive.

SOLUTION: The method for manufacturing a plasma-display-oriented transparent electromagnetic shield film wherein a thin metal film and a thin organic-metal-oxide film are formed in a lamination manner on a transparent film 6 has a process for making the strip transparent film 6 travel by the rotational driving of a take-up reel, etc. and has a process wherein the surface of the transparent film 6 is so coated with an organic-metal-oxide solution by a micro-gravure roll 9 rotated and driven at a specific peripheral speed in the opposite direction to the traveling direction of the film 6 as to form the thin organic-metal-oxide film. By the method, there is obtained the plasma-display-oriented transparent electromagnetic shield film wherein the thin metal film and the thin organic-metal-oxide film are formed in a lamination manner on the transparent film 6.

摘要： PROBLEM TO BE SOLVED: To provide seal structure high in efficiency and airtightness by covering a gel-form seal member, where an optical cable is set in an insertion hole, with a casing member, and also, pressing it with an elastic member at the inside periphery. SOLUTION: A casing member 1 is cylindrical, and the slit 1 that it has in axial direction reaches an optical cable insertion hole 4, and six pieces of resinous springs 2 are attached onto the inside periphery. Moreover, a gel type seal member 3a is charged to stop the space between the resinous springs 2, 2,..., forming an optical cable insertion hole 4 on the inside periphery side of the resinous spring 2, and each gel type seal member 3b is oblong in cross section, and it is mounted along the peripheral face of each outer edge at both ends of the casing member 1. When an end plate is mounted after that, the gel type seal member 3b is transformed by the force of being pressed from the side of the optical cable 3 and the side of the casing member 1, which puts the area between the casing member 1 and the end plate in airtight condition. As a result, seal structure good in work efficiency and airtight condition can be obtained.

摘要： PURPOSE:To provide flexibility capable of sufficiently following the motion of a human body by respectively integrally mounting two almost plate-shaped bodies composed of a living body-active ceramic material to the upper and under surfaces of an almost plate-shaped body composed of a polymer elastic material having bio-compatibility. CONSTITUTION:Two upper and lower layers are formed from hard disc-shaped bodies 10, 11 made of ceramics such as hydroxyapatite and the intermediate layer held between two layers is formed from a disc-shaped body 12 composed of a polymer such as silicone rubber for a living body having bio-compatibility and definite elasticity to constitute a sandwich structure. Therefore, when the upper and lower ceramic disc bodies 10, 11 of this artificial intervertebral disk are bonded to the vertebral bodies of a human body, the upper and lower ceramic disc bodies 10, 11 are freely revolved in a certain degree around the polymer disc body 12 having elasticity as if the intervertebral disk is flexibly connected to the upper and lower vertebral bodies. As a result, since this artificial intervertebral disk flexibly moves in matching relation to forward and rearward movement, the whole of the spine smoothly moves and no unreasonable load is applied to the spine.

摘要： PROBLEM TO BE SOLVED: To obtain a cable closure having not only excellent durability as a sealing material for a cable closure but also improved injection moldability and product yield and to provide a cable closure using the sealing material. SOLUTION: This sealing material for cable closure is obtained by compounding a styrenic base polymer material composed of one or more materials selected from a polystyrene-poly(ethylene/butylene)-polystyrene (SEBS) block copolymer, a polystyrene-poly(ethylene/propylene)-polystyrene (SEPS) block copolymer and a polystyrene polybutadiene-polystyrene (SBS) block copolymer and having >=200,000 molecular weight with a paraffin-based oil material composed of a mineral oil having a high paraffin content and a bisphenol-based antioxidant. The joint part of a cable 8 is coated through sealing materials 3a and 3b with a cover member (a casing 10) in a sealing manner to give the objective cable closure.

摘要： PURPOSE:To provide flexibility capable of sufficiently following the motion of a human body by forming upper and lower columnar or square pillar-shaped regions of a composition prepared by dispersing and adding a living body-active ceramic powder in a polymer elastic material base having bio-compatibility and forming a central region only from a polymer elastic material. CONSTITUTION:The whole is molded into a columnar body 10 and the upper and lower regions A, B thereof are formed from a composition prepared by dispersing and adding a living body active ceramic powder 12 in a polymer elastic material 11 having bio-compatibility and the central region C thereof is formed only from the above-mentioned polymer elastic material 11. Therefore, when the upper and lower end surfaces of this artificial intervertebral disk are bonded to the vertebral bodies of a living body, the living body-active ceramic powder dispersed and contained in the regions A, B is chemically and integrally bonded to the vertebral bodies of a living body. Since the intermediate region part of the artificial intervertebral disk is constituted only of the polymer elastic material and has elasticity, the upper and lower ceramics-containing regions freely revolve around the intermediate region part by a certain degree move flexible and thereby the whole of the spine smoothly moves and no unreasonable load is applied.
