Abstract: A film capacitor having: a stack of at least one dielectric resin film formed of polypropylene and a plurality of vapor-deposited metal films which are superposed on each other such that the at least one dielectric film and the plurality of vapor-deposited metal films are alternately arranged; and two external electrodes formed on a pair of side surfaces of the stack; wherein cover films are formed of a polyolefin-based hot-melt resin on a pair of side surfaces of the stack other than the side surfaces on which the two external electrodes are formed, such that the cover films cover entireties of those side surfaces and are fusion-bonded to end faces of the at least one dielectric film exposed at those side surfaces.

Abstract: An electricity storage device constituted by a stack of a plurality of electricity storage elements superposed on each other and two external electrodes formed on respective opposite side surfaces of the stack, wherein each of the plurality of electricity storage elements has a basic unit obtained by alternately superposing at least one electricity storage film and a plurality of internal electrode films on each other, and two protective films which have an electrical insulation property and which are superposed on respective opposite surfaces of the basic unit as seen in a direction of superposition of the at least one electricity storage film and the plurality of internal electrode films, and the two external electrodes are formed so as to bridge corresponding side surfaces of adjacent ones of the plurality of electricity storage elements.

Abstract: In one aspect of the present teachings, a molding machine includes an injection device and a mold. The injection device can inject molten resin. The mold is directly supported by the injection device and defines a cavity for receiving the molten resin injected by the injection device.

Abstract: An injection device may include an injecting portion, and a material feeding portion having a pelletized resinous material. The material feeding portion includes a cylindrical feeding passage that is communicated with the injecting portion, a screw that is disposed in the feeding passage, and a drive mechanism that is configured to rotate the screw about a rotational axis. When the screw is rotated about the rotational axis by the drive mechanism, the pelletized resinous material can be fed into the injecting portion.

Abstract: A direct molding machine may include a mold engageable with a previously formed substrate, and an injection unit. The mold is arranged and constructed to form a cavity defined by the mold and the substrate when the mold is engaged with the substrate. The injection unit is positioned below the substrate and is arranged and constructed to inject a resinous material into the cavity, so as to form a resin part on the substrate and to connect the same thereto.

Abstract: In one aspect of the present teachings, a torpedo includes a body and a needle pin. The body may have a plurality of blades formed on an outer circumferential surface of the body. The needle pin is received within the body and is axially movable to extend from and retract into a front portion of the body. The plurality of blades may be arranged to ensure a gap between the outer circumferential surface of the body and an inner circumferential wall of an internal space of a nozzle case for receiving a supply of a molten material when the body is received within the internal space. The blades may be formed separately each other.
