  • Publication number: 20090225149
    Abstract: A thermal head avoids a drop in print quality caused by adhesion of printing chaff. A thermal head 39 that presses against thermal paper that moves from one side to the other side and prints by melting dye contained in the thermal paper has a glazed layer 150 that is formed in an area on one part of a ceramic substrate 43 and stores in-flowing heat, and a heating resistor 140 that is located offset to one side from the center of the glazed layer 150, selectively heats the thermal paper S pressed in contact therewith, and melts a dye material contained in the thermal paper. A smooth surface P against which the thermal paper S heated by the heating resistor 140 slides is formed to the other side of the glazed layer 150 from the heating resistor 140.

  • Patent number: 7508836
    Abstract: A data processing apparatus and method are provided for handling transactions issued to a slave device from a master device. Each transaction involves the transfer of one or more data packets between the master device and the slave device. The data processing apparatus comprises a buffer storage operable to buffer the data packets of one or more transactions during transfer of those data packets between the master and slave devices, and buffer control logic is used to control the operation of the buffer storage. In a normal mode of operation the buffer control logic causes the buffer storage to operate as a FIFO storage for buffering the data packets so as to maintain the temporal order of those data packets.

  • Patent number: 7423298
    Abstract: Two operation channels CH1 and CH2 of a bidirectional photothyristor chip 31 are disposed away from each other so as not to intersect with each other. In between a P-gate diffusion region 23 on the left-hand side and a P-gate diffusion region 23? on the right-hand side on an N-type silicon substrate, and in between the CH1 and the CH2, a channel isolation region 29 comprised of an oxygen doped semi-insulating polycrystalline silicon film 35a doped with phosphorus is formed. Consequently, a silicon interface state (Qss) in the vicinity of the channel isolation region 29 on the surface of the N-type silicon substrate increases, so that holes or minority carriers in the N-type silicon substrate are made to disappear in the region. This makes it possible to prevent such commutation failure that when a voltage of the inverted phase is applied to the CH2 side at the point of time when the CH1 is turned off, the CH2 is turned on without incidence of light, and this allows a commutation characteristic to be enhanced.

  • Publication number: 20080048829
    Abstract: A keyless entry device can accurately judge or determine whether a portable device exists inside or outside a vehicle. A vehicle-side controller includes a memory that stores an inside data group having a plurality of intensity information of a request signal transmitted from the plurality of transmitting antennas when the portable device is located along an inside of a vehicle. Also included is an outside data group having a plurality of intensity information of a request signal transmitted from the plurality of transmitting antennas when the portable device is located along an outside of the vehicle. The vehicle-side controller judges an area where the portable device exists from the intensity information of the request signal received from the portable device. The controller instantly judges the inside or the outside of the vehicle, when the portable device exists in an area apart from a boundary.
