摘要:
A detecting means easily detects the abnormality of a generator having a plurality of power supply units. Each of the power supply units includes one of a plurality of output windings L1 to L4, which are wound independently of each other around single iron core, and one of rectifiers 2 to 5 that are provided in correspondence to the output windings and produces an integrated output. Controllers 33 to 35 control the rectifiers such that the output voltage corresponds with a target. A voltage deviation judgment section 37 outputs the abnormal signal when one of the output voltages of the rectifiers 2 to 5 is different from remains. A current deviation judgment section 39 outputs the abnormal signal when one of the output currents of the rectifiers 2 to 5 is different from remains. When the abnormal signal is detected, the outputs of the rectifiers 2 to 5 are stopped.
摘要:
An abnormality of a generator provided with a plurality of power supply units is easily detected. Each of the power supply units includes each of output windings L1 to L4, which are wound independently of each other around the single iron core, and each of rectifier circuits 2 to 5. The power supply units produce an integrated output power. Control means 33 to 35 control the rectifier circuits such that an output voltage agrees with a target voltage Vref. In a case where an added up power W becomes a power target value Wref, when the added up current I further increases, a power comparing section 39 reduces the target voltage Vref to prevent the rectifier circuits from outputting power. Further, when the added up current I exceeds a current upper limit ILMT, a gate pulse is stopped.

An improved thermoplastic resin composition obtained by subjecting a mixture of at least an engineering plastic and a rubber material containing an .alpha.,.beta.-unsaturated carboxylic acids or their derivatives, to dynamic heat treatment in the presence of a carbon radical inducing agent. The thermoplastic resin composition of the invention excels in thermal resistance, rigidity, impact resistance, and moldability.

An active vibration noise control apparatus uses an adaptive control process, which predicts rear road wheel noise canceling sounds by correcting a front road wheel reference signal or a rear road wheel reference signal with a corrective filter, based on different characteristics of front road wheel suspensions and rear road wheel suspensions.

An advertisement selecting system is disclosed providing, when selecting advertisements to be exposed to subscribers over the Internet, exposure control reflecting the inventory of advertisements by taking into account results of past exposure of each of the advertisements. When subscribers with a particular profile biased to specific tastes or preferences gain access to contents carrying advertisements, the first-ranked advertisement, i.e., the one best targeted for the subscribers in question, is exposed repeatedly but in a manner also making way for the advertisements in second and subsequent places which would be less likely to be exposed if handled conventionally, so that the stocked advertisements are exposed in fairly averaged fashion. Advertisement exposure is thus controlled in a manner averting lopsided exposure of certain (or partial) advertisement information by giving consideration to the advertisement inventory.
摘要:
An ANC apparatus using so-called adaptive control is provided with a cancellation sound output means which outputs front wheel cancellation sound that cancels front wheel vibration noise due to front wheel vibration at a position to be silenced on the basis of a front wheel reference signal, and outputs rear wheel cancellation sound that cancels rear wheel vibration noise due to predicted rear wheel vibration at the position to be silenced on the basis of a rear wheel reference signal, and a turning state detection means which detects a turning state of a vehicle. When a difference in travel trajectory between a front wheel and a rear wheel is detected on the basis of the turning state, the cancellation sound output means suppresses the output of the rear wheel cancellation sound.

An active sound control apparatus includes a delay circuit for delaying the output of a frequency component of a sound effect by delaying an engine rotation frequency signal representative of an engine rotation frequency [Hz], a delay circuit for delaying the output of an amplitude component of the sound effect by delaying an engine rotation frequency change signal representative of an engine rotation frequency change [Hz/second], and delay circuits for delaying the output of all components of the sound effect by delaying a control signal for controlling the outputs of speakers.

An active acoustic control apparatus includes an alert sound signal generator configured to generate an alert sound signal. An alert sound output device is configured to output an alert sound to an outside of a vehicle. A cancellation sound signal generator is configured to generate a cancellation sound signal representing a cancellation sound to cancel the alert sound, which has been transferred from the outside of the vehicle to an inside of the vehicle, at a sound cancellation target position inside the vehicle. A cancellation sound output device is configured to output the cancellation sound to the sound cancellation target position. The cancellation sound signal generator is configured to detect change of a transfer characteristic from the alert sound output device to the sound cancellation target position and to vary an output characteristic of the cancellation sound depending on the change of the transfer characteristic.

A control apparatus for an internal combustion engine of a vehicle sets the overlap amount of an intake valve and an exhaust valve small when the engine is idling and the vehicle is stopped. Also, the control apparatus sets the overlap amount large using normal control when the vehicle is traveling, even if the engine is idling.
