Abstract: PROBLEM TO BE SOLVED: To inhibit a temperature rise in an optical-disk library device, and to improve reliability to dust by installing partitions among a storage shed, a medium carrier mechanism section and a power supply section and a data recording reproducer, and a control section. SOLUTION: In a data recording reproducing device 2, a cartridge inserting hole is formed on the storage shed 1 side, but a substrate 45 for the device is mounted on the lower side and covers 46 on side faces and the upper side and enclosed structure is formed by parts for the device on the rear side on the side rearer than a parting plate 17. Each part is connected through packings, and structure, in which dust on the outside does not enter to the inside of the device 2 and the cartridge storage shed 1 side, is formed. The device is formed in dustproof structure, but cold air collides against the substrate 45 for the device 2, to which cooling is required. Power supply sections 11 and the storage shed 1 and the device 2 and control sections 16 are separated by the parting plate 17.  In a library device, holes for taking in the outside air are bored to the power supply sections 11 and the top face and underside of a section, on which the device 2 is mounted. A hole taking in the outside air is also bored to the right side of the device 2.

Filed: 1994-03-31
Abstract: PURPOSE:To save the space required for opening and closing front doors adapted to be opened and closed in a bi-folded condition, by interposing a seal member between the coupling parts of the front doors, and by engaging lock pins to a front surface plate so that the lock pins are projected from the top and bottom surfaces of the doors when the doors are closed. CONSTITUTION:When a grip 41 is gripped by a hand to open a front door 30 of a dryer, lock pins 33 are released from locking holes by means of a link mechanism, and accordingly, the front door 30 can be opened. During opening of the front door 30, door segments 31, 32 constituting the front door 30 are bent in an angle shape directing outward of a body casing since the coupling parts of the door segments 31, 32 are rotated relative to each other. When the door is closes, the coupling parts of the door segments 31, 32 are sealed in an air-tight manner by a seal member, and further, the opening end side of the front door 30 is fixed to the front surface plate by a wedge 34. Accordingly, it is possible to surely prevent the front door 30 from opening during operation of the dryer, thereby it is possible to effectively avoid leakage of steam.

Abstract: PURPOSE:To effectively prevent short-circuit at a contact part, by forming a re-diffusing region, whose diffusion depth is smaller than that of an impurity diffusing region having a large diffusion depth and whose surface concentration is smaller than that of the impurity diffusing region. CONSTITUTION:Up to the process on which an n<+> diffusion layer 11 and p<+> diffusion layer 10, serving as respectively source and drain areas in n-channel and p-channel transistors, are formed, the process is quite the same as the conventional one. On this process, a silicon oxide film 12 is piled all over the surface, and contact-holes 13 are formed by anisotropic etching, and then phosphor serving as n-type impurity is injected through openings for the source and drain. At this point, a diffusion depth of a diffusing region, in which an injection is performed after the diffusion, is made smaller than that of the p<+> diffusing region 10, and the surface concentration is made smaller than that of the p<+> diffusing region 10. Heating after ion injection forms an n<-> diffusing region 15, whose depth is smaller than that of the p<+> diffusing region 10 and larger than that of the n<+> diffusion region 11. Thereafter, aluminum is vaporized to form wirings 14.

IPC: G06F5/14
Filed: 1985-03-27
Abstract: PURPOSE:To select automatically an appropriate data transfer speed corresponding to a load by switching the data transfer speed slower by means of retrial when data overrun occurs. CONSTITUTION:With the aid of an I/O controller 1, a data buffer 2 transfers data between a channel and an I/O device. A channel interface control circuit exchanges a channel and a data transfer control signal according to an indication from a data transfer control circuit 4. Its data transfer speed is controlled by a control processor 5, and made lower in accordance with the value of an overrun counter 7. After a data transfer request signal IN is transmitted, an overrun detecting circuit detects such a case as the overrun that a data transfer reporting signal OUT is not responded.

Abstract: PURPOSE:To make a motor into flat form and reduce the number of parts by forming a chuck plate integrally onto the edge surface of the housing of a permanent-magnet shaped rotor and accommodating the edge part of the permanent magnet into the housing and using a chuck circuit in common. CONSTITUTION:A motor magnetic circuit is constituted of a rotor magnet 6 inside a motor, and a magnetic circuit is constituted between a chuck magnet part 6a and an installed article on the upper surface side of a rotor housing 2, namely on a seat standard surface 2a side. The motor is fixed onto the inner bottom surface of a housing 10, and when the disc hub 12 of a magnetic disc 11 is brought into contact with the seat standard surface 2a, the chuck magnet part 6a attracts the disc hub 12 and holds it rotatably in the state where the center part is positioned onto a seat standard shaft 3b. Since the chuck magnetic circuit and the magnetic circuit for the revolution of the motor are constituted of only the rotor magnet of the motor, the whole can be made thin and the number of parts can be reduced.

Title: Data-reproducing circuit
Inventor: KANESHIGE TOSHIHIKO
IPC: G11B20/18
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of data errors in digital data as much as possible by performing an error-correcting treatment to digital data generated from outputs of a level slice means based on a first error detection signal. SOLUTION: Registers 30, 31 hold sampling values immediately before, immediately after digital data output from an adder circuit 26 cross a slice level. An instantaneous slew rate output from an adder circuit 32 is sent to an average value circuit 34, whereby an average slew rate is calculated. When the instantaneous slew rate is smaller than a value obtained by subtracting a judging value from the average slew rate, an H is output from a large-small comparison circuit 35. When circuits 35, 40 and 35, 41 output H level outputs, an error correction pulse-generating circuit 44 judges that the sampling values held immediately after, immediately before by the registers 31, 30 include errors, and outputs an H output. As a result, an output of a system delay circuit 45 is reversed in polarity by an EX OR circuit 46, so that the errors are corrected.

Filed: 1992-03-19
Abstract: PURPOSE:To improve the light distributing characteristic of a storoboscope by providing a rugged pattern which diffuses storoboscopic light on the back surface of a diffusion plate arranged on the front surface of a storoboscopic electric discharge tube and changing the thickness thereof according to a distance from a lens. CONSTITUTION:The front surface of the diffusion plate 12 interposing the storoboscopic electric discharge tube 10 between a reflector 11 is flat and in parallel with a film unit with a lens. However, the rugged pattern 14 is integrally formed on the back surface thereof. The individual ruggedness of the pattern 14 is rough on a side near a photographing lens and it becomes finer as it is distant from the photographing lens. Therefore, a degree that the storoboscopic light is diffused is small on the side near the lens and much on the side distant from the lens. Besides, much storoboscopic light is gathered to the lens side by the fine rugged pattern on the side distant from the lens. When the plate 12 is shaped so that the thickness thereof is thin on the side near the lens and it becomes thicker as it is more distant from the lens, the range of a photographic picture can be uniformly illuminated.
