A cartridge (2) contains a recording disk (4) having photosensitivity. The cartridge comprises a cartridge shell (11), a light shielding plate (12) and a shutter (13). The cartridge shell has an internal opening (18) for exposing a central portion and a recording surface of the recording disk to the outside. The light shielding plate is attached to an outer side of the cartridge shell and has an external opening (14) confronting the internal opening. The shutter is slidably disposed between the cartridge shell and the light shielding plate to open and close the internal opening. A lock mechanism locks the shutter in a closed position. For releasing the lock mechanism, it is necessary to slide a first lock member (63), which is exposed through a cavity (72), in a state that a second lock member (64) projecting into a groove (7) is pushed into the cartridge shell.

A cartridge is composed of a cartridge body and a shutter. A hologram recording disk is rotatably contained in a disk recess formed in the cartridge body. The shutter comprises upper and lower shutter plates between which the cartridge body is interposed. The shutter opens and closes openings formed in both surfaces of the cartridge body. When the shutter is kept in a closed position where the openings are closed, the edges of the shutter are inserted into slits formed around the opening. Further, a groove is formed at an end portion of the shutter. Into the groove, a ridge formed on the cartridge body is inserted.

For suppressing generation of leakage current and side-gate effect in a junction field effect transistor, a gate extension is formed on a semi-insulative compound semiconductor substrate in a manner to extend from a gate and to protrude outward beyond a channel transversely thereto, and an insulating layer is formed on the semi-insulative compound semiconductor substrate under the gate extension. A method of producing this transistor comprises the steps of first forming a channel and a source-drain on a substrate, then forming a gate on the channel together with a gate extension which extends from the gate and protrudes outward beyond the channel transversely thereto, and forming an insulating layer adjacently to the channel and the source-drain in such a manner that no gap is existent between the insulating layer and at least the channel.
摘要:
An object of providing an injection-molded polylactic acid resin article composed of a resin composition with a polylactic acid resin content of 50% by weight or more, which has a higher strength than conventional articles and is applicable as a constituent part for larger products with heavier weights such as copying machines and printers, is achieved by providing a molded article obtainable by injection molding of a resin composition containing a polylactic acid resin and super engineering-plastic fibers. For the molded article as provided, the lactic acid component content A (% by weight) and the super engineering-plastic fiber content B (% by weight) of the resin composition, the mean thickness X (mm) and the weight Y (kg) of the molded article, as well as the length L (μm) and the cross-sectional diameter D (μm) of the super engineering-plastic fibers satisfy specified relations.

Provided is an injection-molded article of a fiber-reinforced polylactic acid resin, which is excellent in mechanical strength and flame retardancy, and still has a high recyclability. The injection-molded article of a fiber-reinforced polylactic acid resin has a mean thickness of 2.0 mm or more, and is obtainable by injection molding of a resin composition containing components (1) to (3) below: (1) at least 50 parts by weight of a polylactic acid resin; (2) 10 to 25 parts by weight of petroleum-based fibers with a melting point of 200 to 300° C.; and (3) 2 to 10 parts by weight of a monomeric phosphate ester.
摘要:
Light-trapping members are cut out of a ribbon consisting of a base fabric and piles. The piles of the ribbon are pressed against the peripheral surface of a thermal drum to be inclined in the width direction after the ribbon is passed through and twisted by a twister disposed close to the thermal drum. The light-trapping members with inclined piles are attached to a film passage mouth of a self-advancing-type photographic film cassette with the inclination of the piles directed to the outside of the film passage mouth, so that the leading end of a photographic film can be advanced smoothly by rotation of a spool through the light-trapping members to the outside of the cassette.
