Abstract: A heat insulating layer contains many hollow particles, a silicone-based resin binder, and silica nanoparticle. The percentage of the silica nanoparticles in the total amount of the resin binder and the silica nanoparticles is equal to or greater than 10% by volume and equal to or smaller than 55% by volume.

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.

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.

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.

Abstract: In forming a plating layer for a sliding portion, which comprises Cr that is electrolytically-deposited in a plating bath containing Cr, the plating bath contains organic sulfonic acid. Accordingly, micro-cracks are formed at the plating layer. The plating layer for a sliding portion has the superior low friction and lubricating property.
