  • Voltage conversion apparatus and electrical load driving apparatus to reduce noise through magnetic field
    Patent number: 9088202
    Abstract: The present invention is related to a voltage conversion apparatus having a first loop circuit and a second loop circuit which share an inductance component, in which a current passes through the first and second loop circuits alternately in accordance with ON/OFF operation of a first switching element provided in the first loop circuit, characterized in that a direction of a magnetic field through the first loop circuit generated at the ON operation of the first switching element in the first loop circuit is the same as a direction of a magnetic field through the second loop circuit generated at the OFF operation of the first switching element in the first loop circuit subsequent to the ON operation.

  • Onboard reception device, and noise cancellation method for onboard reception device
    Patent number: 8023916
    Abstract: This onboard reception device includes: a first receiver; a second receiver which is tuned to a second frequency which is different from a first frequency to which the first receiver is tuned, and whose reception level is low; a noise cancellation means which cancels noise included in a first demodulated received signal which is demodulated by the first receiver, based upon a second demodulated received signal which is observed by the second receiver; and an output means which outputs the first demodulated received signal in which noise has been cancelled, in a manner in which it can be appreciated by a user.
