  • Patent number: 5182072
    Abstract: A process involving mixing an ethylene/vinyl acetate copolymer and an organopolysiloxane at a temperature of at least 160.degree. C. for a sufficient length of time to provide a melt index of 0.05 to 8 grams per 10 minutes.
    Type: Grant

  • Patent number: 5005797
    Abstract: The door mirror according to the present invention is a so-called tiltable door mirror for vehicles. The bearing member to bear the shaft of the mirror base which is to be fixed to the vehicle door is formed integrally with the synthetic resin-made mirror housing. The bearing member is formed as a bearing cylinder inside the mirror housing. Being in contact with the bearing surface of the bearing cylinder, the shaft pivotably supports the mirror housing. There is provided between the inner wall of the bearing cylinder and the shaft a U-shaped leaf spring which is in contact at the one end thereof with the inner wall of the bearing cylinder and at the other end with the flat surface formed at a part of the shaft, whereby the friction generated under the action of the leaf spring helps to block the mirror housing from pivoting and thus the mirror housing can be held in the normal position. The shaft has disposed at the end thereof a stopper to prevent the mirror housing from moving axially of the shaft.

  • Patent number: 4786156
    Abstract: A remote control side mirror device for a vehicle capable of rotating a mirror housing with respect to a mirror base fixed to an automotive body by a motor driven remote control. The motor driven by a remote control is fixed in the mirror housing to rotate a first gear through a reduction gear. A support shaft for rotatably supporting the mirror housing vertically is formed at the mirror base, and a second gear engaged in mesh with a first gear is arranged at the mirror housing side of the support shaft. Since the second gear is stationarily connected by the frictional force to the support shaft through a friction transmitting mechanism. When the motor is driven, the mirror housing is rotated around the support shaft of the mirror base. When the mirror housing receives a strong external force, the second gear can slide around the support shaft to prevent the reduction gear from damaging.

  • Patent number: 4648986
    Abstract: Compositions based on mixtures of ethylene-ethyl acrylate copolymers and ethylene-vinyl acetate-vinyl chloride terpolymers which have adhesion to and strippability from crosslinked olefin polymers. Compositions of this invention, which are rendered semi-conductive by the addition of carbon black thereto, are especially useful as outer layers bonded to layers of crosslinked olefin polymer insulation of electrical conductors.
