  • Publication number: 20230253292
    Abstract: A cooler has a cooling main body portion that includes: a cooling wall in the Y direction including a first face with a heat generator thereon, and a second face opposite thereto; first and second flow path extending in the Y direction, the first flow path allowing refrigerant to flow in, and the second flow path allowing the refrigerant to flow out; cooling flow paths with a part of a wall surface comprising the second face; a partition spaced from the cooling wall in the Z direction, separating the first and the second flow paths from the cooling flow paths; and a first narrowing portion at a communication portion between a cooling flow path and the first flow path. The cooling flow paths are positioned between the first and flow paths and the cooling wall, and cause the first and the second flow path to communicate in the X direction.

  • Patent number: 8771118
    Abstract: A chain tensioner device having a first slide surface of a main arm pivotably supported at an upper end thereof, and a second slide surface of a sub-arm pivotably supported at a lower end thereof. The first and second slide surfaces slidably abut against each other. When the main arm is biased toward a timing chain via the sub-arm by a biasing force of a plunger of a tensioner lifter, a stroke of the main arm is increased with respect to a stroke of the plunger.

  • Patent number: 4671912
    Abstract: A sintered ceramic body is manufactured first by preparing a composition containing a binder and a ceramic powder having a particle size distribution given such that 0 to 1 weight % of ceramic particles with a particle size of less than 0.2 .mu.m, 0 to 2 weight % of ceramic particles with a particle size of 0.2 .mu.m to less than 0.5 .mu.m, 5 to 15 weight % of ceramic particles with a particle size of 0.5 .mu.m to less than 1.0 .mu.m, 5 to 15 weight % of ceramic particles with a particle size of 1.0 .mu.m to less than 1.5 .mu.m, 5 to 15 weight % of ceramic particles with a particle size of 1.5 .mu.m to less than 2.0 .mu.m, and 50 to 80 weight % of ceramic particles with a particle size of not less than 2.0 .mu.m. The prepared composition is then injection-molded into a predetermined shape. The binder is removed from the molded body, and the binder-free molded body is sintered.
