  • Publication number: 20200241430
    Abstract: To provide a control apparatus, with which driving of a driving unit can be controlled with high accuracy with a simple configuration, the control apparatus (100) according to the present invention include: a plurality of current sources (20) each being configured to supply current based on a PWM method; a first detection unit configured to detect a driving state of a driving unit (14); and a control unit (50) configured to change values of a plurality of currents (Ixf, Ixb, Iyl, and Iyr) which are supplied from the plurality of current sources (20) based on a result of the detection by the first detection unit, and which are required to drive the driving unit (14), when a value of at least one of the plurality of currents (Ixf, Ixb, Iyl, and Iyr) is a predetermined value.

  • Patent number: 9748658
    Abstract: First and second hot elements are formed on the front surface of a long and thin substrate. First and second earth elements are formed on the rear surface of the substrate. First and second parasitic elements are disposed adjacent to the hot elements and the earth elements, thereby forming a first-stage element. A second-stage element has a corresponding structure. A first branch line and a second branch line are formed on the front surface. The hot elements of the first-stage and second-stage elements are fed from a feeding point through the first and second branch lines. An earth line is formed on the rear surface. The earth elements of the first-stage and second-stage elements are fed from the feeding point through the earth line. The hot element and the earth element form a dipole antenna. The parasitic element is disposed adjacent to the dipole antenna to broaden a frequency band.
