  • Patent number: 6052342
    Abstract: Even if a recorded medium is exchanged during the reproduction of another recorded medium, the contents of the exchange work can be confirmed easily. A stocker accommodates a plurality of recorded medium carriers each holding a recorded medium. A first transport unit transports a recorded medium carrier between the outside of an apparatus housing and the stocker. A second transport unit transports a recorded medium between the stocker and a reproduction unit. The stocker is moved up and down in order to align the position of the recorded medium carrier with the first or second transport unit. While a recorded medium carrier is transported from the outside of the housing to the stocker, light emitting and receiving elements detect a presence/absence of a recorded medium. A control unit stores information of a presence/absence of a recorded medium at each stage of the stocker, and displays the contents of the information on a display unit.

  • Patent number: 6049092
    Abstract: A TFT formed on an insulating substrate source, drain and channel regions, a gate insulating film formed on at least the channel region and a gate electrode formed on the gate insulating film. Between the channel region and the drain region, a region having a higher resistivity is provided in order to reduce an loff current. A method for forming this structure comprises the steps of anodizing the gate electrode to form a porous anodic oxide film on the side of the gate electrode; removing a portion of the gate insulating using the porous anodic oxide film as a mask so that the gate insulating film extends beyond the gate electrode but does not completely cover the source and drain regions. Thereafter, an ion doping of one conductivity element is performed. The high resistivity region is defined under the gate insulating film.

  • Patent number: 6047914
    Abstract: A notched ring rotates together with a spool and opposes a disk of a locking shaft portion. A substantially semicircular engaging projection is formed on an opposing surface of the notched ring in the peripheral direction thereof. An engaging concave portion is formed at the disk so as to correspond to the engaging projection. When the spool is rotated in the withdrawing direction of a webbing and the opposing surface of the notched ring abuts the disk, the engaging projection enters and engages the engaging concave portion without clearance therebetween. Accordingly, even if rotating force is further applied to the spool in the withdrawing direction of the webbing, movement of the notched ring in the outer peripheral direction is prevented, and a state in which the rotation of the spool is restricted is maintained.

  • Patent number: 6046793
    Abstract: A proximity printing device in which the angle of the light with which a workpiece is irradiated can be changed has an exit part attached on a base and a light source part supported by two bearings. Light emitted from a lamp is focused by an oval focusing mirror and is radiated onto the workpiece via a mask. In one embodiment, two ends of the base are joined to guides of arc-shaped arms. Rotating the base tilts the exit part and the workpiece can be obliquely irradiated with light. Because the light source part is held by two bearings, the lamp of the light source part can be held in a vertical state even when the base is tilted. Furthermore, the direction of motion of the light source part can be limited by means of a ball spline or the like to a horizontal direction, and can be moved by means of a drive so that the exit part can be tilted while holding the light source part vertical.

  • Patent number: 6043470
    Abstract: For use in the heating of foodstuffs by induction, use is made of an energy converter between energy taken from the mains supply via a rectifier and a high frequency oscillation. Such a converter is frequently based on the maintenance of an oscillation in a parallel resonant circuit (CR, LR) which may be disposed in a converter bridge (S1, S2, S3, S4) of controlled switches. It has turned out to enhance the efficiency considerably to let the parallel resonant circuit be series connected to a self-inductance L1 which connects it to the DC source UDC. A series resonant circuit is thereby created which is active during supply of energy and which in a simple fashion reduces the load on the participating switches.
