Abstract: Provided is a boot seal for a variable compression ratio engine having an inner layer free from tears or creases. The boot seal comprises a boot body having a cylinder-attaching part, a crankcase-attaching part and a connecting part for connecting these parts, and a rigid plate disposed in at least one of the cylinder-attaching part and the crankcase-attaching part and having a through hole. The boot body comprises an outer layer formed by injection molding a rubber material, and an inner layer formed of fluorine-containing rubber. An injection gate for the outer layer is located at a portion of the outer layer opposing the rigid plate. Both an outer surface and an inner surface of at least a portion of the rigid plate having the through hole are covered with the rubber material supplied from the injection gate.

Abstract: A battery module comprises a battery element and a storage unit configured to contain the battery element therein. The storage unit comprises an electrically conductive positive electrode-side plate and an electrically conductive negative electrode-side plate. The positive electrode-side plate and the negative electrode-side plate define a storage space to contain the battery element therein. The storage unit has a joint end provided on the periphery of the storage space and formed by joining an outer peripheral area of the positive electrode-side plate with an outer peripheral areal of the negative electrode-side plate across an insulating sheet placed between the two outer peripheral areas. The joint end comprises: a wind part formed by stacking and winding the two outer peripheral areas to be pressure-bonded to and joined with each other; and an outer peripheral frame body formed by insert molding using an insulating resin to surround the wind part.

Abstract: A high thermal conduction insulator exhibiting thermal conductivity, insulating properties and heat radiating properties is produced by supplying a molding material composed of an insulating resin, a diamagnetic material powder and a paramagnetic material (inclusive of ferromagnetic material) powder, and exhibiting fluidity into a mold, and applying a magnetic field to the molding material in the mold to orient clusters, each being composed of diamagnetic material particles of the diamagnetic material powder, which are joined together like a chain, along directions of lines of a magnetic force, and draw the paramagnetic material (inclusive of ferromagnetic material) powder with the magnetic force along one of mold surfaces of the mold, thereby forming a heat radiating layer. Heat transmitted from a facing member to one surface of the insulator is speedily transmitted to the other surface thereof via the clusters, and is effectively radiated from the heat radiating layer existing in the other surface.
