  • Patent number: 12116052
    Abstract: Control calculation units of a back system in each actuator operate by a collaborative drive mode in which a torque is output to a motor drive unit by using an information transmitted and received mutually by a communication between the systems in common. Cooperative control calculation units in a reaction force actuator and a turning actuator can operate in cooperation with each other based on the information transmitted and received mutually by a communication between actuators. A communication between adjacent systems and a communication between adjacent actuators are restored, when a focus control calculation unit is restored, after the focus control calculation unit is stopped during operation and at least one of the communication between adjacent systems or the communication between adjacent actuators is interrupted.

  • Publication number: 20080252549
    Abstract: An antenna device for television broadcast reception includes an antenna element including a base member and a radiating conductor, and a matching circuit. A feed signal is supplied to the antenna element via the matching circuit. The matching circuit includes a variable capacitance element (varactor diode), a first inductance element connected in parallel to the variable capacitance element, and a second inductance element connected in series with the variable capacitance element. A capacitance value of the variable capacitance element is changed to change a resonant frequency of the antenna element. The variable capacitance element and the first inductance element form a parallel circuit, and a resonance point of the parallel circuit is set to a frequency lower than the resonant frequency of the antenna element. As the resonant frequency increases, the resonance point is shifted to a high-frequency side.
