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.

Abstract: An electromagnetic drive-type die casting decompression valve comprises a drive shaft, provided inside a drive block, driven by electromagnetic force from a solenoid, and a valve shaft, provided inside a valve block separate from the drive shaft, provided with a valve body on one shaft end. Also, a closing spring working jointly to urge the valve body in a closing direction is provided on the valve shaft, while an opening spring working jointly to urge the valve body in the opening direction is provided on the drive shaft. The valve block is also provided in a replaceable manner. According to this type of electromagnetically driven die casting decompression valve, bouncing is not caused at the time of closing a decompression valve, and it is also possible to significantly decrease maintenance time and repair costs even when problems arise, such as molten metal infiltrating into a valve body.

Abstract: The presence/absence of an image information request signal HSYNC output from each of a plurality of display devices is monitored. Based on the monitoring result, image information stored in an image memory of a display controller incorporated in a host computer is distributed to each display device.

Abstract: A throttle opening degree detecting apparatus in accordance with the present invention is structured such that a resin gear is connected to a throttle shaft of a throttle valve, a permanent magnet is mounted to a part of the resin gear, and an opening degree of the throttle valve is detected by detecting a rotation angle of the resin gear on the basis of an output signal from a magnetic sensor arranged in a fixed side so as to oppose to the permanent magnet in a non-contact manner. A depressed boss portion is formed in a position of an axis of the resin gear, a yoke and the permanent magnet is mounted along an inner peripheral surface of the boss portion, and the resin gear is insert molded by a synthetic resin by inserting the yoke and the permanent magnet.

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.

Abstract: A display control apparatus for a display device capable of performing updating of a display state for a display element subjected to a change in display includes a display data memory for storing display data, a display controller capable of sequentially reading out the display data stored in the memory and transferring the readout display data to the display device at a predetermined period and capable of performing a partial rewrite operation of the display data stored in the memory, and a rewrite detector for detecting an address for accessing the display data memory to cause the display controller to perform the partial rewrite operation. In addition, a transfer permitting unit reads the address detected by the rewrite detector and permits transfer of only the display data of the read address to the display controller.

Abstract: A disturbance of an image in the case where a display format is switched during the display operation is prevented without exerting an adverse influence on the operation of a display apparatus side.

Abstract: A display control apparatus includes a storage unit for storing display data at each position corresponding to a display screen of a display device, a setting unit for setting a read start position of the display data from the storage unit, and a data supply unit for reading out display data in a predetermined amount from the storage unit on the basis of the read start position set by the setting unit and supplying the readout display data to the display device. The read start position set by the setting unit is set on the basis of the display data stored in the storage unit. A display control method is also disclosed.

Abstract: A display control apparatus includes a memory for storing information supplied from a processing apparatus, a detector for detecting a storage portion of the information, a display controller for performing display on a display device on the basis of the information stored in the portion detected by the detector, and a limiting unit for limiting the portion detected by the detector.

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.

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.

Abstract: A high quality display image is displayed on a screen by providing an; image area information generator means (203) for generating image area information for designating an area for displaying binarization image data to be obtained by image processing of image data in the multi-level frame buffer on the screen and the area for displaying binarization image data to be obtained by approximate color conversion, based on a computer software, and a processor for processing the image data based on the image area information.
