Abstract: A disk apparatus has a tilting mechanism including an insulating resin cap that is attached in such a way as to cover an end portion of a metallic shaft and that has insulation performance, a metallic adjusting screw attached to a chassis in such a way as to abut against a bottom surface of the insulating cap attached to the shaft for moving the end portion of the shaft in an upward/downward direction, a resin shaft receiving pedestal that is attached to the chassis and that supports the end portion of the shaft movably in an upward/downward direction, and a metallic leaf spring that is attached to the shaft receiving pedestal, that abuts against an upper surface of the insulating cap attached to the shaft and that pushes the insulating cap in such a way as to press the insulating cap attached to the shaft against the adjusting screw.

Abstract: There are provided a disc tray, a traverse unit, and a main chassis unit. The main chassis unit has a main chassis, which has, as observed when the traverse unit is in a stand-by position, a latch portion that engages with a projection portion of a sub rack and a stopper member that restricts the movement of the cam slider. The stopper member has a rotary shaft in the shape of a circular column, a lever portion which the projection portion makes contact, and a lock portion that makes contact with the cam slider and thereby restricts the sliding movement of the cam slider.

Abstract: Gate oxides having different thicknesses are formed on a semiconductor substrate by forming a first gate oxide on the top surface of the substrate, forming a sacrificial hard mask over a selected area of the first gate oxide; and then forming a second gate oxide. A first poly layer may be formed on the first gate oxide, under the hard mask. After the hard mask is removed, a second poly layer may be formed over the second gate oxide and over the first poly layer. This enables the use of high-k dielectric materials, and the first gate oxide can be thinner than the second gate oxide.

Abstract: A recording-medium mis-recording preventing mechanism for preventing recording from being made by mistake on a recording medium loaded in a recording unit, comprises: a push switch for detecting whether the recording medium is recordable or not; and an arm portion. The arm portion includes: a first arm member pivoted on the recording unit and having a detection portion for abutting against a judgement claw provided on the recording medium so as to be removable by bending; a second arm member for pushing the push switch; a thin plate portion for connecting the first arm member and the second arm member; a spring provided between the first arm member and the second arm member for urging the second arm member in the direction to push the push switch; and a plate spring portion provided on the first arm member for making the arm portion return to a position in which the arm portion is to be positioned when no recording medium is loaded.

Abstract: A magnetic tape apparatus having a bearer formed so as to be reciprocatable in the front-rear direction between a cassette insertion position and a cassette mount position on a chassis for inserting a tape cassette, and a rotating cam provided on the chassis for driving the bearer through an interlocking mechanism with a clutch. In the magnetic tape apparatus, the clutch is turned off to release the interlocking mechanism between the bearer and the rotating cam when the bearer is advanced from the cassette mount position to the cassette insertion position, while the clutch is turned on to establish the interlock between the bearer and the rotating cam when the bearer is retreated from the cassette insertion position to the cassette mount position.

Abstract: A loading mechanism in a video cassette deck comprising a cassette moving mechanism 100 for moving a cassette receiving portion 200 between an initial location and a running location. The cassette moving mechanism 100 has a slide arm 120 horizontally slidably attached on one of a pair of wall portions 110 provided on both left and right sides of the cassette receiving portion 200, a driving portion for sliding the slide arm 120, a cassette driving gear 130 which is rotatably supported on the wall portion 110 to which the slide arm 120 is attached and which is connected to the cassette receiving portion 200 through a groove portion 112 formed in the wall portion 110, and a door arm 140 for transmitting the motion of the slide arm 120 to a door. The cassette loading mechanism is designed so that the door is opened before the cassette receiving portion 200 is moved when the cassette receiving portion 200 in the running location is moved into the initial location.

Abstract: A device for securing a pinch roller support arm to a chassis of a magnetic tape apparatus. In the device, the chassis includes a round hole which is formed such that it extends through the chassis, and a securing part is outsert molded in the chassis in such a manner that the securing part extends through the round hole. After the pinch roller support arm is fitted with a support shaft provided on and projected from the chassis and a projection provided on the pinch roller support arm is fitted into a fitting hole formed in the chassis, by rotating the securing part around the round hole, the securing part is engaged with the projection.

Abstract: A non-volatile semiconductor memory device is implemented in a manner which allows programming and erasing at low voltage. The non-volatile semiconductor memory device includes a plurality of blocks, each including a plurality of wordlines acting as control gates, buried diffusion layers acting as sources and drains, metal lines arranged one for every two buried diffusion layers, and memory cells formed between the two buried diffusion layers. Block transistors are connected to both ends of the buried diffusion layers for connecting the buried diffusion layers to the corresponding metal lines. The buried diffusion layers of each block are connected through the block transistors in the form of a bellows.

Abstract: An apparatus which allows automatic winding of a sheet-formed article such as, for example, of foamed rubber without being influenced by the material or dimensions of the article. In the apparatus, an end of a sheet-formed article which is continuously transported by a conveyor is turned over to partially surround and press against the periphery of a tubular takeup member by means of an attaching roller assembly. Then, the turned over end of the sheet-formed article is pushed to a position below the tubular takeup member by means of a presser so that the end of the article is wrapped between the tubular takeup member and the sheet-formed article being fed by the conveyor and is thus fixedly attached to the tubular takeup member, thereby allowing subsequent automatic winding of the sheet-formed article onto the tubular takeup member to be effected by rotation of the tubular takeup member.
