Abstract: The present invention provides a lidded container which, even when a flange portion of the container warps during microwave heating, can prevent a contact between the flange portion and a lid and allows steam to pass from a steam escape mechanism. The lidded container is provided with a container having an opening and a lid which covers the opening and is joined to the container. The container is provided with a bottom portion, a side portion standing upright from the bottom portion, and a flange portion which is continuously connected to an upper portion of the side portion and includes a first plane. A circumferential seal portion is formed between the lid and the first plane of the flange portion. The seal portion is provided with a main seal portion and a protruding seal portion protruding inward with respect to the main seal portion.

Abstract: A soft, meshed, electromagnetic shielding textile sheet is placed in a mold, and the mold is clamped. The soft, meshed electromagnetic shielding textile sheet is shaped so as to conform with the inner surface of the mold when the mold is clamped. Therefore, it is not necessary to fabricate beforehand any insert of a shape corresponding to that of the inner surface of the mold. Since the meshed, electromagnetic shielding textile sheet is impregnated with part of a resin injected into the mold to form an injection-molded resin body, the adhesion of the electromagnetic shielding textile sheet to the injection-molded resin body is improved.

Abstract: A disk cartridge comprises a case including an upper and lower shell halves for accommodating a disk and an opening portion provided on each shell half, so as to be opened and closed by a shutter. Each shell half is formed by an injection molding of polycarbonate in which a mold having a single injection hole is used. The injection hole is formed in the mold, at a position opposed to a center of a groove in its longitudinal direction on a surface of the case for receiving a retaining plate to guide a front portion of a slide plate of the shutter. The injection hole has a diameter of about 1.5 mm in case of a 5-inch disk cartridge.

Abstract: A disk cartridge with a case comprises upper and lower shell halves, each of which has a head insertion hole and a spindle insertion hole. A pair of projections are provided inwardly at a joint portion between the two holes. The peripheral wall portions of the spindle insertion hole are extended inwardly toward tips of the projections in an arched form. An almost annular projection is provided along a periphery of the spindle insertion hole to increase a supporting portion for supporting the disk when the spindle is taken off from the spindle insertion hole. The inner peripheral walls of the head insertion hole are chamfered. A corner of the groove is chamfered to prevent the corner of the groove from being caught by a part of the guide frame.

Abstract: A disk cartridge comprises a case with an upper and a lower shell halves united together to accommodate a disk of 3.5 inches therein, a guide portion, a shutter, and a slider slid in the guide portion of the case for supporting the shutter. The shutter is moved by a drive pin to open and close a head and spindle holes. The slider enables the shutter to move smoothly along the guide portion and prevents the shutter from being disconnected from the guide portion when the case is dropped.
