  • Publication number: 20100035626
    Abstract: A radio network control apparatus includes a free channel counting unit to count the number of free channel identifiers in a range between a last-used channel identifier of the radio network control apparatus itself and that of its peer apparatus. A channel identifier acquiring unit then selects a free channel identifier, based on the number of free channels counted by the free channel counting unit, thus preventing the two radio network control apparatuses from selecting the same channel identifier.

  • Patent number: 6249738
    Abstract: In apparatus and method for controlling a vehicular velocity for an automotive vehicle, when a controller carries out a preceding vehicle follow-up control to follow up a preceding vehicle which is traveling ahead of the vehicle and is decelerated and a vehicular velocity of the vehicle becomes reduced and has crossed a set lower limit value of the vehicular velocity in a vehicular velocity controllable range, the controller releases the preceding vehicle follow-up control but continues a braking operation through a vehicular brake system using a function generator (Pbrk*=f(t)MPa) to prevent a sudden G drop from occurring.

  • Patent number: 6104624
    Abstract: Buck-boost type or buck type chopper circuits and transistors are employed as inverters (IV1, IV2) and power synchronizing switches (SW1, SW2), respectively. A PWM signal is applied to transistors of the chopper circuits to convert DC voltage generated by solar cells (DC1, DC2) into positive and negative half-wave AC voltages for an AC power supply (AC1). The inverters (IV1, IV2) output the AC voltages from their AC output terminals on alternate half cycles thereby to cause backflow of power. The power synchronizing switches (SW1, SW2) performs not only the function of transmitting the half-wave AC voltages generated by the inverters (IV1, IV2) to the AC power supply (AC1) in accordance with the AC cycle of the AC power supply (AC1), but also the function of, when one of the inverters is in operation, insulating the other from the AC power supply (AC1).

  • Patent number: 4639676
    Abstract: The diagnostic device comprises voltage divider resistors, two comparators, a start switch, a microcomputer, two transistors, and two light emitting diodes. The ignition signal is voltage-divided by the voltage divider resistors, and the result of this voltage division is input into the positive terminals of the comparators. Reference voltages are input to the negative terminals of the comparators which determine how high the inputs to the positive terminals must be for each comparator to have an "H" level output. When the start switch is turned ON the device starts to operate. In the microcomputer, which has a timer function built in, the interrupt terminal (INT) becomes connected to the output terminal of the comparator; the reset terminal (RES) becomes connected to the start switch.
