  • Patent number: 10161297
    Abstract: A heat-insulating layer exhibiting high resistance to cracks, peeling, deformation, and gasoline and high heat insulation is obtained on the wall surface of an engine member (19). First, a heat insulator layer including a silicone-based resin and hollow particles containing a Si-based oxide is formed on a wall surface of the engine member (19). Then, Si-based oxide is produced through oxidation of a silicone-based resin in at least part of the surface of the heat insulator layer by heating the surface of the heat insulator layer. Thereafter, a catalytic metal is added to the silicone-based resin in the surface of the heat insulator layer and/or Si-based oxide derived from the hollow particles. Using the catalytic metal as nuclei, electroless plating is performed. In this manner, a heat-insulating layer (21) in which the surface of the heat-insulating film (27) is covered with a plating film (29) is obtained.

  • Publication number: 20160025035
    Abstract: A heat-insulating layer (21) provided on a surface of a component (19) facing an engine combustion chamber contains hollow particles (23) made of an inorganic oxide, a filler material (25), and a vitreous material (27) containing silicic acid as a main constituent. The vitreous material (27) is not in powder form, and surrounds and bonds the hollow particles (23) and the filler material (25) together.

  • Publication number: 20080236219
    Abstract: There are provided a striker, a latch to engage with the striker, the latch including a restriction portion operative to restrict a movement of a closure in a direction of a rotational axis of the closure by contacting the striker, wherein a low-friction material having lubricant function is provided at a contact portion of at least one of the striker and the restriction portion. Accordingly, there can be provided a lock device of a closure for a vehicle equipped with the restriction portion at the latch that can improve responsiveness of deformation of a vehicle body properly.
