Abstract: Foam forming techniques capable of permitting foaming of biodegradable resin to be positively and uniformly accomplished to provide a biodegradable resin foam with satisfactory quality. The biodegradable resin foam is made of biodegradable resin consisting of a main biodegradable resin ingredient of 100° C. or more in melting point and a low-melting biodegradable resin ingredient of 100° C. or less in melting point. The biodegradable resin foam is produced by placing a starting material consisting of at least biodegradable resin and a substantial amount of moisture in a heated and pressurized environment, releasing the starting material from the environment to foam the biodegradable resin, and subjecting the foamed resin to forming by means of a forming mold. An apparatus for producing the foamed biodegradable resin foam includes a pressure adjusting chamber, an air-permeable forming mold, a pressure reducing tank and an injection machine.

Abstract: An inertia damper is capable of exhibiting satisfactory endurance. In the inertia damper, when an inertia weight element directly carrying out a damping action and a gel element are combined together, the gel element is interposedly arranged between the outer periphery of the inertia weight element and the inner surface of a peripheral cover section of a holding member of a mount base. This permits the area of arrangement of the gel element to be increased to significantly reduce loading per unit area of the gel element, thereby improving the endurance.
