  • Patent number: 5951435
    Abstract: For a toroidal type continuously variable transmission, the end portion of a radial needle bearing provided for a trunnion is protruded from the inner face of the trunnion. Also, the inner face of the trunnion is made substantially flat. Therefore, the processing of the trunnion is made easy, and the holder of the thrust needle bearing can be easily positioned simultaneously. Also, the structure is arranged to enable the recess formed on the trunnion to engage with the extrusion formed on the holder, thus preventing any plane pressure from being exerted excessively on the rolling surface of the needles of the thrust needle bearing, as well as preventing the needles from falling out of the pockets of the holder.

  • Patent number: 5830103
    Abstract: A sufficient quantity of lubricating oil can be sent into a radial needle bearing and a thrust ball bearing supporting a power roller. The lubricating oil is discharged into a gap space through a send-in side oil supply path formed in a trunnion, and is sent into a receiving side oil supply path in a pivotal support shaft portion. A thrust sliding bearing having a through-hole is provided in the gap space. The downstream end opening of the send-in side oil supply path and the upstream end opening of the receiving side oil supply path are located inside the through-hole.

  • Patent number: 5180792
    Abstract: Disclosed is a curable epoxy resin composition which is effectively cured at ambient temperature and when cured has excellent adhesive strength and good water resistance. The epoxy resin composition comprises:(a) an epoxy resin having at least two epoxy groups in one molecule,(b) a monofunctional (meth)acrylate represented by ##STR1## wherein R.sub.1 represents a hydrogen atom or an alkyl group having 1 to 12 carbon atoms, R.sub.2 and R.sub.3 respectively represent a hydrogen atom or a methyl group, and n is an integer of 1 to 4, and(c) An amine curing agent selected from the group consisting of an aromatic polyamine, a modified aromatic polyamine, a polyamideamine and a mixture thereof. The present invention also provides an adhesive composition prepared from the above mentioned curable epoxy resin composition.

  • Patent number: 4943730
    Abstract: A charged particle beam lithography method wherein the workpiece material is mounted on a stage the position of which is detected by a laser interferometer. Patterns are expanded or reduced by a scaling factor by the steps of adjusting the gain of the deflection system controlling the charged particle beam and adjusting the size of movements of the stage in accordance with the scaling factor.
