  • Patent number: 10287685
    Abstract: Provided is a susceptor capable of achieving improved thermal uniformity while suppressing reduction in its temperature increase rate and heat utilization efficiency. A susceptor includes a plate-shaped first member including a wafer placement surface on which to place a wafer, and a second member supporting the first member and laid on the first member in the direction perpendicular to the wafer placement surface. The thermal conductivity of the first member is higher than the thermal conductivity of the second member.
    Type: Grant
    Filed: August 29, 2014
    Date of Patent: May 14, 2019
    Assignee: MARUWA CO., LTD.

  • Patent number: 10035395
    Abstract: A vehicle leaf spring shackle includes pair of longitudinal plate members opposed to each other, pair of devices for connecting the pair of longitudinal plate members to each other at their opposite end portions with respective predetermined spacing distances, and between pair of longitudinal plate members, one pair of devices is coupled to a member of a vehicle body while other pair of devices is coupled to one end portion of a leaf spring device provided to suspend the vehicle body. At least one end portion of the pair of longitudinal plate members on the leaf spring device side including a thick-walled portion formed with thickness larger than other portions of the pair of longitudinal plate members, the thick-walled portion is formed by press-forming operation to press at least one end portions of the longitudinal plate members on the leaf spring device side, in direction of the end portion plane.
    Type: Grant
