  • Patent number: 6901469
    Abstract: A communication control apparatus for performing an arbitration when a collision of frames occurs on a bus has a plurality of message boxes. Each message box stores at least a message for a transmission purpose and an identification code indicative of both a priority degree and a sort thereof. The apparatus determines whether the transmission of the frame is successful, and stops a transmission of bits when the transmission of the frame fails. The apparatus further detects a specific event, which delays the transmission of the frame, and sets a sequence of the message box related to the specific event as a first sequence by selecting any one of the low transmission sequence message boxes instead of the highest transmission sequence message box.

  • Patent number: 6881922
    Abstract: The present invention uses as a detector for adjustment measurement, monodyne interference between a microwave for plasma generation and the reflected wave. Analysis of the interference wave that is obtained using monodyne interference allows finding of the phase difference between the incident and the reflected wave and the amplitude of that reflected wave; and controlling of an excited microwave generation/control system based on them allows impedance matching between the excited microwave and the plasma. This method allows very high precision phase detection, and calculation of the characteristics of the plasma based on the detected phase shift. Therefore, it is possible to distinguish noises even in the vicinity of the matched region.

  • Publication number: 20050080508
    Abstract: This invention provides a board positioning method where a stopper and so on are not required when positioning a printed board in an X direction. Servo motors of a board supplying conveyer portion and a board positioning portion are driven to start carrying of a board. When a first board detection sensor detects the board before timeout of a first timer which starts timekeeping together with the carrying of the board, second and third timers start timekeeping. The servo motor starts decelerating, decelerates to an arbitrary speed, and keeps a constant speed after timeout of the second timer. When a second board detection sensor detects the board before timeout of the third timer, the servo motor is controlled to decelerate and stop the board at an arbitrary position, and a board recognition camera takes an image of a positioning mark of the board stopping at the board positioning portion to recognize a position of the printed board.

  • Publication number: 20050003126
    Abstract: In a fuel hose composed of an inner single layer or multilayer of a fluororesin and an outer single layer or multilayer of a thermoplastic resin, any two materials for the layers have a ratio 1:40 or below in melt viscosity as expressed in Pa·s. The wall formed by having its inner and outer layers co-extruded is free from any unevenness in thickness that would occur if their materials had a larger ratio in melt viscosity. Thus, it is impermeable to fuel, and has an improved adhesion between its inner and outer layers.
