Abstract:
An optical information medium having an ink-accepting layer that may secure a high-gloss printed surface similar to print image quality of print image on photographic paper is provided. The optical disk is constituted by sequentially laminating concavo-convex information pits, a recording layer, a reflective layer, a protective layer, a second printing layer, and an ink-accepting layer on a transparent substrate made of synthetic resin such as polycarbonate. In the formation of the ink-accepting layer, the following proportions of the following constituents in percent by weight are milled to prepare an ink for printing: 5 to 15% urethane acrylate; 70 to 80% water-soluble monomer; 5 to 15% water-soluble monomer soluble resin; 5 to 15% photopolymerization initiator; 5 to 15% dyestuff fixing agent; and
Abstract:
The present invention is relative to a disc cartridge in which an optical disc (3), an inner shell (4) and shutter members (5a), (5b) are housed in a main cartridge body unit (2), formed by abutting and combining upper and lower shells (6), (7), and in which the inner shell is run in rotation to cause the shutter members (5a), (5b) to open or close an aperture (24) provided in the main cartridge body unit (2). On an inner side of the peripheral wall sections of the upper and lower shells, abutted to each other, a crank-shaped dust intrusion prohibiting unit (21A) is provided for prohibiting intrusion of dust and dirt from the abutting surfaces of the peripheral wall sections of the upper and lower shells towards the optical disc housed in the main cartridge body unit to protect the optical disc housed in the main cartridge body unit. The inner shell provided in the main cartridge body unit includes an aperture (44) in register with an aperture in the main cartridge body unit, and includes a connecting portion (43a) bridging an open end side of the aperture. This connecting portion has a height not protruding towards the lower shell.
Abstract:
A bearing unit is provided which includes a shaft (51) to support rotatably, radial bearing (55) to support the shaft (51) circumferentially, a thrust bearing (66) to support the shaft (51) in the direction of thrusting, and a housing (56) having the radial bearing (55) and thrust bearing (66) disposed therein and in which a viscous fluid (57) is filled. The housing (56) has a sealed structure except for a shaft insertion hole (65) formed therein and through which the shaft 51 is introduced. Between the outer surface of the shaft (51) and the inner surface of the shaft insertion hole (65), there is defined a gap (69) having a sufficient width to prevent the viscous fluid (57) filled in the housing (56) from leaking out of the latter. The housing (56) is formed as a one-piece structure by molding a synthetic resin.

Abstract:
A withstand voltage against electrostatic discharge of a high voltage MOS transistor is improved. An N−-type drain layer is not formed under an N+-type drain layer, while a P+-type buried layer is formed in a region under the N+-type drain layer. A PN junction of high impurity concentration is formed between the N+-type drain layer and the P+-type buried layer. In other words, a region having low junction breakdown voltage is formed locally. The surge current flows through the PN junction into the silicon substrate before the N−-type drain layer below a gate electrode is thermally damaged. Hence, the ESD withstand voltage is improved.
Abstract:
An engageable pawl member is provided so as to be swingable about a supporting shaft so that a pawl tip is movable along a moving path for a strapping band. The engageable pawl member is pulled forwardly in a swinging direction by a helical tension spring to push the pawl tip against the strapping band. The engageable pawl member shifts forwardly, following the movement of the strapping band in a feeding direction, and the strapping band is sandwiched and held between the engageable paw member and a holding guide. Then, the engageable pawl member follows the movement of the strapping band in a direction to pull back, and the engageable pawl member shifts backwardly so that the pawl tip moves in a direction out of the moving path for the strapping band.
Abstract:
A semiconductor device is provided with a gate electrode formed over a substrate that has gate oxide films disposed thereon. Source-drain regions of low and high concentration are formed next to the gate electrode. A diffusion region width of the source side of the source-drain regions is smaller than at least a diffusion region width of the drain side.

To enable the reduction of ON-state resistance in a state in which the withstand voltage is secured, a semiconductor device according to the invention is provided with a gate electrode formed so that the gate electrode ranges from a gate oxide film formed on an N-type well region formed in a P-type semiconductor substrate to a selective oxide film, a P-type source region formed so that the source region is adjacent to the gate electrode, a P-type drain region formed in a position apart from the gate electrode and a P-type drift region (an LP layer) formed so that the drift region surrounds the drain region, and is characterized in that a P-type impurities layer (an FP layer) is formed so that the impurities layer is adjacent to the drain region.
Abstract:
To provide a new shutter open/close mechanism suitable for use with a cartridge body (6) whose front end is formed in an arbitrary shape for easily knowing a correct direction of insertion in a recorder/player, a guide recess (36) to support a shutter plate (25) movably is formed on a main side of the cartridge body (6) to be oblique relative to the width of the cartridge body (6). The shutter open/close mechanism (26) includes a guide member (31) supporting the shutter plate (25) and movably engaged in the guide recess (36), an operating member (32) to move the guide member (31), a transmission member (33) connecting the guide member (31) and operating member (32) to each other to transmit an operating force from the operating member (32) to the guide member (31), and support surfaces (37) formed on the cartridge body (6) to support the operating member (32) movably. The transmission member (33) is pivotably connected to the guide and operating members (31) and (32).
