  • Patent number: 6971264
    Abstract: A throttle opening degree detecting apparatus includes a resin gear, a permanent magnet, a yoke and a magnetic sensor. The resin gear is connected to a throttle shaft of a throttle valve and provided with a depressed boss portion in an axial position. The permanent magnet is mounted and secured along an inner peripheral surface of the boss portion in the resin gear without an adhesive. The yoke is mounted and secured along the inner peripheral surface of the boss portion in the resin gear without an adhesive. The magnetic sensor is arranged in a fixed side so as to oppose to the permanent magnet in a non-contact manner and outputs a signal indicating a rotation angle of the resin gear as an opening degree of the throttle valve. The resin gear is insert-molded with the yoke and the permanent magnet.

  • Patent number: 6378270
    Abstract: A powder grain material control unit has a cylindrically formed filter and a negative pressure chamber formed at the outer periphery of the filter. As powder grain material is discharged from an outflow portion of the powder grain material control unit, the inner peripheral portion side of the cylindrical filter is negatively pressurized so as to absorb and maintain the powder grain material of this part on the cylindrical filter side and so as to stop the discharge of the powder grain material flowing on the inner peripheral portion side of the cylindrical filter. The control unit may be used in combination with a powder grain filling unit that includes material carrying means which may be an auger having a spiral blade provided with a central axis of rotation.

  • Patent number: 5907329
    Abstract: It can be determined without visually observing the display screen of a display device whether image conversion processing in a conversion circuit for outputting image data to the display device is being performed normally. The conversion circuit extracts data at a position designated from a host apparatus from image data output to the display device, and outputs the extracted data to the host apparatus. In the host apparatus, image data obtained upon normal conversion in the conversion circuit is prepared in advance, and this image data is collated with the data sent from the conversion circuit to determine whether the operation of the conversion circuit is normal.

  • Patent number: 5880702
    Abstract: An image is displayed in an optimum state in accordance with the state of a display. For this purpose, an FLCD interface mounted in an information processing apparatus and an FLCD for actually displaying an image are connected through a data transfer bus for transferring image data to be displayed and a serial communication line for performing communications between them. When the FLCD detects a change in its own state, this information is supplied to a CPU of the FLCD interface through the serial communication line. An instruction for changing, e.g., the operating mode is also transmitted from the FLCD interface to the FLCD through the serial communication line.
