  • Patent number: 10680307
    Abstract: A substrate is used as one tube wall of a hollow waveguide, the substrate including a strip line wired in an inner layer, a first ground surface formed on a front surface, and a second ground surface formed on a part of a back surface. As a result of such a configuration, a waveguide strip line transducer having the same dimension as the external dimension of the hollow waveguide can be obtained.

  • Patent number: 9385529
    Abstract: Power supply current is supplied to a plurality of electric loads, the power supply current being generated by a DC power supply, flowing in and branching from a shared power supply switching device and then flowing in reverse connection protection devices that are a field-effect transistor and connected in series to the electric loads, respectively. The reverse connection protection devices are connected in a polarity such that the power supply current flows in the forward direction of parasitic diodes generated between the source terminal S and the drain terminal D of the field-effect transistor. When the current in the field-effect transistor is less than a predetermined value, a gate control circuit interrupts the gate voltage of the reverse connection protection device to cause the reverse connection protection device to open.

  • Patent number: 9029186
    Abstract: A method for forming an electrode of a solar battery on an electrode forming face of a semiconductor substrate, comprises: applying a resin containing a conductor material to be the electrode onto an electrode forming region of the electrode forming face; causing a pattern transfer member, on which a reverse pattern obtained by reversing a pattern of the electrode is formed, to face the electrode forming face, and registering the pattern transfer member on a position in which the electrode is to be formed in the electrode forming face; pressing the pattern transfer member against the electrode forming face to transfer the electrode pattern to the resin containing the conductor material; separating the pattern transfer member from the resin containing the conductor material; and baking the electrode pattern transferred to the resin containing the conductor material to form the electrode on the electrode forming face of the substrate.

  • Publication number: 20100147805
    Abstract: A power-supply control device includes a high-frequency component detecting unit, a machining voltage level detecting device, a no-load time detecting device, and a pulse control device. The high-frequency component detecting unit detects a high-frequency component of discharge voltage at a machining gap. The machining voltage level detecting device detects a discharge voltage level at the machining gap. The no-load time detecting device detects delay time of discharge of the discharge voltage at the machining gap. The high-frequency component is compared with a reference value to obtain a first comparison result. The discharge voltage level is compared with a reference level to obtain a second comparison result. The pulse control device controls pulse off time based on the first comparison result and the detected delay time, and cuts off a discharge pulse based on the second comparison result.

  • Publication number: 20080230118
    Abstract: A printing mask includes a mask frame and a mesh extended on the mask frame, in which a mask portion is formed by filling the mesh with resin to leave a pattern forming portion in a region corresponding to an electrode pattern to be formed on a printing object. The mask portion has a raised part on a surface of the mesh to be opposed to the printing object. The thickness of the raised part is such that a difference in average film thickness between the end and other parts of the electrode pattern formed with the printing mask is equal to or less than 5 micrometers.

  • Publication number: 20080193020
    Abstract: A method of detecting an object, in particular a face, in an image using template matching uses at least two different templates for the same object. Templates are provided for left eye, right eye and between-the-eyes. A confidence map is produced for each template and the confidence maps are merged. This may take place at several resolutions. The detected regions are further checked with symmetry, texture and/or geometrical relationship to other facial parts.

  • Publication number: 20080143398
    Abstract: A PLL circuit has an averaging device for averaging a rectangular wave signal output from a phase comparator at every period of a reference clock signal, and for outputting the average value. After the establishment of the phase synchronization of the PLL circuit, the average value of the averaging device becomes a stationary reference level. Accordingly, the output clock signal generated by a voltage controlled oscillator can reduce its output frequency fluctuations in accordance with the reference level.
