摘要： A process for producing an aging-resistant rubber material, in which even when a rubber layer has been formed from an aqueous rubber latex, the heat resistance thereof can be improved without impairing its moldability. Even when an antiblocking treatment with an antiblocking agent is conducted, this does not lead to a cost increase. The process comprises applying a coating fluid containing an amine aging inhibitor dissolved or dispersed therein to a surface of a crosslinked rubber material and then heating the rubber material to 80°C or higher to diffuse the amine aging inhibitor thereinto and thereby produce an aging-resistant rubber material. When the coating fluid is one which contains an antiblocking agent dissolved or dispersed therein besides the amine aging inhibitor, then the crosslinked rubber material as a product simultaneously undergoes an antiblocking treatment.

摘要： A sealing apparatus capable of increasing a grease resistance property, wherein the tip of a sealing lip is formed so that an inner side contact angle alpha is equal to an open-air side contact angle beta ( alpha = beta ), that is, formed in a triangular shape to prevent grease inside the apparatus from leaking so as to increase the grease resistance property, and since the extending direction of the sealing lip is set at a middle of an inner side and an open-air side, a trouble such as the inversion of the sealing lip due to the occurrence of an inner pressure does not occur.

摘要： A magnetic fluid seal device, comprising a groove (11) separating the surface of a member (10) without magnetic fluid (4) from the magnetic fluid (4) when two members (10, 20) are located at specified stop positions and a seal member (5) sealing a clearance when the two members are located at the specified stop positions, wherein, because the magnetic fluid is positioned at the groove and separated from the surface of the member (10) when the two members are stopped, the surface treatment on the surface of the member (10) is not deteriorated at the opposed position to the magnetic fluid when the two members are stopped to prolong the service life of the device and, because the seal member seals the clearance between the two members when the two members are stopped, the device can maintain an excellent sealability.

摘要： A high-pressure shaft seal (10A) which can be used in a refrigerating machine using CO2 gas as a refrigerant instead of CFCs, and which is provided with a high-gas-barrier seal lip (24A) formed from a polymer material such as nylon having a small gas permeability to a high-pressure CO2 gas, and a non-elastomer property, wherein an area, in contact with a shaft to be sealed , in the seal lip is lined with a low-friction polytetrafluoroethylene lining (26A). The gas-barrier seal lip (24A) can effectively block CO2 gas permeation under very high pressures of about 4 MPa to 12 Mpa. A nylon seal lip (24A), having a comparatively high rigidity, can be flexibly elastic-deformed under such high pressures, elastically follow up a shaft deflection, and deliver sufficient dynamic and static seal functions.

摘要： To provide a method of producing a torsional damper to prevent an annular rubber undulation in the pressing of the annular rubber between a hub and an annular mass, improve strain durability of the torsional damper, and decrease a press-in load in the press-in of the annular rubber, and enhance axial and radial run-out accuracy of the annular mass to a hub bore portion. To this end, in the method of producing the torsional damper made by pressing the annular rubber in an axial direction between the hub and the annular rubber, a silane coupling agent is applied to the hub faces and the annular mass between which faces the annular rubber is pressed, and the agent is dried. A fitting liquid is then applied to any one of the hub, the annular mass or the annular rubber, and the annular rubber is pressed between the hub and the annular mass.
