摘要： A first transmitter outputs a request signal requesting a response to a mobile device toward an area including a driver's seat and its neighborhood, and a second transmitter outputs a request signal toward an area covering the entire vehicle. The mobile device transmits a response signal to a receiver if receiving the request signal transmitted from the first or second transmitter. The controller detects the position of the mobile device based on a communication result between the mobile device and the receiver in response to the request signals transmitted from the first and second transmitters.

摘要： A disk drive apparatus reproduces an information signal from a disk and/or records an information signal on the disk. FET power transistors of a power supplying part execute high-frequency switching operation and form current paths to three-phase windings so as to rotate the disk. A voltage detecting part compares terminal voltages of the three-phase windings and produces a detected pulse signal in response to a comparison result. An activation operation block controls active periods of the FET power transistors in response to the detected pulse signal. A commanding part produces a command signal in response to an output pulse signal of the voltage detecting part. A switching operation block produces a switching pulse signal in response to a comparison result of a current-detection signal with the command signal, and causes at least an FET power transistor of the power supplying part to perform high-frequency switching in response to the switching pulse signal. The switching operation block changes a timing of the switching pulse signal in response to detection of the detected pulse signal so that the voltage detecting part can accurately achieve the next detection of the detected pulse signal. Further, an excellent speed control of the disk can be achieved by the accurate output pulse signal of the voltage detecting part.

摘要： FET power transistors of a power supplying part execute high-frequency switching operation and form current paths to three-phase windings. A voltage detecting part compares terminal voltages of the three-phase windings and produces a detected pulse signal in response to a comparison result. A state shifting part and an activation control part control active periods of the FET power transistors in response to the detected pulse signal. A commanding part produces a command signal in response to an output pulse signal of the voltage detecting means. A switching operation block produces a switching pulse signal in response to a comparison result of a current-detection signal with the command signal, and causes at least an FET power transistor of the power supplying part to perform high-frequency switching in response to the switching pulse signal. The state shifting part produces a timing signal after an adjust time from the detection of the detected pulse signal and shift-holds a holding state in response to the timing signal. The state shifting part changes the adjust time smaller in case that the command signal is larger than a predetermined value, thereby making the product value of the adjust time and the rotational speed smaller in the case.

摘要： First power transistors of first power amplifying parts and second power transistors of second power amplifying parts form current paths from a DC power source to three-phase windings. A first distribution control block activates the first power amplifying parts with first three-phase signals, each having an active electrical angle larger than 120 degrees. A second distribution control block activates the second power amplifying parts with second three-phase signals, each having an active electrical angle larger than 120 degrees. A switching operation block has a current detecting part and a switching control part. The current detecting part obtains a current detected signal corresponding to a composed supply current of negative or positive parts of the three-phase drive currents to the three-phase windings. The switching control part compares an output signal of the current detecting part with a command signal and switches at least one power transistor of the first power transistors and the second power transistors to an off state when the output signal of the current detecting part becomes a value corresponding to the command signal, thereby causing the at least one power transistor to perform high-frequency switching responding with a comparison result.

摘要： LF antennas are mounted respectively on the corners of a rear bumper of a vehicle. Radio waves radiated from the LF antennas mounted respectively on the corners of the rear bumper are propagated to the both surfaces of the vehicle on the opposite sides of the corner, providing effective transmission ranges. The remaining LF antennas are mounted respectively on the side surfaces of the vehicle such that their effective transmission ranges overlap the effective transmission ranges of the LF antennas mounted respectively on the corners of the rear bumper.
