  • Patent number: 10794455
    Abstract: A tensioner includes a power spring, and a backup member being in contact with the power spring and supporting the power spring by acting an urging force in a direction opposite to a radial shift of the power spring in a direction in which the power spring is wound. The power spring is unwound in a condition in which an inter-plate frictional force of the power spring is small in a case where an urging force acting from a power spring to a tension member is greater than a load acting from the tensioner arm to the power spring and the power spring is wound in a condition in which the inter-plate frictional force of the power spring is large in a case where the urging force acting from the power spring to the tension member is smaller than the load acting from the tension member to the power spring.

  • Patent number: 10403559
    Abstract: In a power semiconductor device, the thickness dimension of a protective film of a semiconductor element is made smaller than that of an upper electrode, so a protective film is not pressed by being pressurized from upward when bonded by a metal sintered body, and the force of tearing off the upper electrode riding on an inclined surface of the protective film does not act, so that no crack of the upper electrode occurs, thus maintaining the soundness of the semiconductor element. Also, a lead bonded by a solder to the upper electrode of the semiconductor element is made of a copper-Invar clad material, the linear expansion coefficient of which is optimized, and thereby it is possible to realize a durability superior to that of a heretofore known wire-bonded aluminum wiring.
