  • Patent number: 10464581
    Abstract: A carbody support device of a railway vehicle, including support mechanisms installed between a front bogie and a carbody and between a rear bogie and the carbody in a traveling direction, and supporting the carbody against the respective bogies. The support mechanisms regulate both the front bogie and the rear bogie inclining in the same vehicle width direction with respect to the carbody when the railway vehicle travels through a curve, while the support mechanisms permit the front bogie and the rear bogie inclining in different vehicle width directions.

  • Patent number: 8558435
    Abstract: A piezoelectric device has a piezoelectric vibration element mounted in a package wherein the piezoelectric vibration element comprises two stick-like vibration legs; a central leg provided between the two vibration legs; a coupling portion that couples one end of each of the two vibration legs and one end of the central leg; and a protrusion portion that is coupled to another end of the central leg, has a predetermined angle, neither 0 nor 180 degrees, to the length direction of the central leg, and extends into a direction not interfering with the driving legs. In making the piezoelectric device smaller and thinner, this configuration avoids interference between a support point on the central leg, provided for supporting the vibration element, and conductive electrodes, improves insulation between the conductive electrodes, and reduces the generation of short-circuits between the conductive electrodes.

  • Patent number: 8179022
    Abstract: A piezoelectric device, having a piezoelectric vibrating piece and a circuit element being electrically connected, is provided with a package for storing inside at least the piezoelectric vibrating piece of the piezoelectric device. The package is made up of a substrate and a cover body, and on the outer surface of the package, an electrode terminal electrically connected to at least the circuit element or the piezoelectric vibrating piece is provided. The electrode terminal includes an external connecting terminal which is electrically connected with an external circuit board and an input-output terminal which is electrically non-connected with the external circuit board, at the time of mounting the package on the external circuit board.

  • Publication number: 20090315881
    Abstract: In case it is necessary to have high-speed drawing processing such as display scrolling and so on, a drawing switching signal is input at a step, and high-speed drawing display data is output to a display at a step in response to this input, thereby display is performed. A high-speed drawing data generating means generates high-speed drawing display data for displaying each pixel concerning a character or visual object using a digitized gradation value digitized from each corresponding gradation value, and display is performed on this generated data. When it is necessary to have high-speed drawing, it is possible to have quick processing without increasing loads on a CPU and graphic controller on digitized data from gradation value.

  • Publication number: 20090174715
    Abstract: A font controller extracts and reads each time only the pre-rasterized bitmap font data groups to be used simultaneously among a plurality of pre-rasterized bitmap font data groups stored on the hard disk drive in advance, and expands and stores the groups in a work memory. With this arrangement, it is possible to significantly decrease the amount of memory consumed because the memory capacity required in the work memory is sufficient only with the read data amount to be extracted.

  • Publication number: 20060175939
    Abstract: A piezoelectric element plate is rectangular as seen from above. Its upper surface is formed to be flat, while it lower surface has a beveling arc applied thereto. The piezoelectric plate is mounted on a package by adsorbing one longitudinal end of its upper surface (flat surface) by an adsorbing nozzle. Then, ultrasonic waves are applied through the adsorbing nozzle to a bump positioned between the package and one longitudinal end of the lower surface of the piezoelectric element plate, while pressing the piezoelectric element plate against the package by the adsorbing nozzle, whereby the piezoelectric element plate is joined to the package.

  • Patent number: 6094957
    Abstract: A method is provided for bending a difficult-to-work metallic wire into a complicated profile. A predetermined length of the difficult-to-work metallic wire is prepared. Part of a portion thereof is held by a conductive clamping device. A first conductive pressure member is brought into contact with a first bending work position of the workpiece, while applying a predetermined pressing force thereto, electric power is supplied between the first member and the clamping device via the wire. Thereby, the wire is bent by a predetermined amount, which part of the wire thus bent by the predetermined amount is located on a conductive rod having a circular cross-section. A second conductive pressure member is brought into contact with a second bending work position of the wire, while applying a constant pressing force to the second member, electric power is supplied between the second member and the conductive rod via the wire.
