Abstract: A method of manufacturing a hydrogen separation membrane with a carrier is characterized by including a first step of providing, between the hydrogen separation membrane and the carrier that supports the hydrogen separation membrane, a low-hardness metal membrane having a hardness that is lower than the hardness of the hydrogen separation membrane, and a second step of joining the hydrogen separation membrane, the low-hardness metal membrane, and the carrier by a cold joining method. In this case, it is possible to suppress the deformation of the hydrogen separation membrane, the low-hardness metal membrane, and the carrier and, as a result, it is possible to prevent damaging of the hydrogen separation membrane. The adhesion of the contact between the hydrogen separation membrane and the carrier is also improved. The result is that it is not necessary to increase the severity of the cold joining conditions.

Abstract: A variable compression ratio device includes a piston having a piston inner part and a piston outer part. The piston outer part integrally includes ear parts facing opposite ends of a piston pin and having long holes with longer diameters directed in an axial direction of a piston. A shaft portion connected to the opposite ends of the piston pin is slidably fitted in the long holes to allow an axial relative movement between the piston inner part and the piston outer part, while preventing relative rotation between the piston inner part and the piston outer part. Thus, the variable compression ratio device reliably prevents the relative rotation between the piston inner part and the piston outer part with a simple structure, and reduces weight of the piston.

Abstract: A variable compression ratio device of an internal combustion engine includes a piston inner part connected to a connecting rod and a piston outer part fitted on an outer periphery of the piston inner part. The piston outer part is only slidably in an axial direction, and is movable between a low compression ratio position near the piston inner part and a high compression ratio position near the combustion chamber. A skirt part is slidable and is guided by an inner peripheral surface of a cylinder bore of an engine. The skirt part is integrally formed on the piston inner part. A peripheral wall of the piston outer part is terminated directly above the skirt part. Thus, switching of the position between the low compression ratio position and the high compression ratio position by an inertia force of the piston outer part is performed smoothly with a reduction in weight of the piston.
