Abstract: A large-current circuit board having a plurality of fasteners positioned and secured beforehand to the circuit board, and a plurality of busbars for electrically connecting the plurality of fasteners. Each of the plurality of busbars has a strip-like planar plate shape. Various ones of the plurality of fasteners may have the same or different distances from the surface of the circuit board. Specifically, the portions of the fasteners that are connected with the busbars may be at different heights so that plural busbars connecting the fasteners can cross each other at plural levels. A variety of fasteners and busbar securing boards may be used for electrically connectibly holding and securing the plurality of busbars with the plurality of fasteners on the circuit board.

Abstract: A method of preparing a large-current printed circuit board comprises inserting a fastener with a bottom flange in a through-hole formed in a printed circuit board so that the bottom flange is engaged with a surface of the printed circuit board, putting a washer having substantially the same outer diameter so the flange around the fastener at the other surface of the board, forming a radial extension at the outer side of the washer by caulking the fastener, whereby the fastener is fixed to the printed circuit board by means of the radial extension and the bottom flange wherein the washer is interposed between the radial extension and the printed circuit board.

Abstract: Printed circuit boards with busbars for providing large current interconnections are disclosed. The printed circuit board 6 has through holes through each of which a cylindrical fixture member 12 having a top nut portion 12b extends to be secured to the board 6 by means of the bottom flange 12p and the radial outward extension 12a formed by a pressing or caulking step. Each one of the leads 4 of circuit elements 3 has a pin-shaped end portion having a male thread 4a formed thereon which engages with the nut portion 12b of a fixture member, wherein the pin-shaped portion 4a of each lead extends through a through hole formed in the busbars 1 so that the busbars 1 are securely held between the fixture members 12 and the stoppers (radial extensions) 4b formed at the base of the pin-shaped portions 4a of the leads 4. Alternatively, the busbars 1 are held between two radial outward extensions 12a and 12A of each one of the fixture member (FIG.

Abstract: An output circuit of a stereo type audio device includes a switch state detection switch which responds to an open state of a normally closed internal switch of an output jack of a first channel to separate a stereo signal source from the first and a second channels of the stereo device and connect a monoral signal source to the second channel.

Abstract: A vehicle control system in accordance with the present invention permits a vehicle to move only in the case where both of a device for detecting the content of a signal for directing the travelling speed of the vehicle transmitted from the trackside and a device for detecting the presence of the above signal perform detecting operations. The apparatus also comprises a device for detecting an abnormal operation of both the above mentioned devices, so that a runaway of the vehicle can be avoided. In addition, a voltage signal can be used for detecting the speed, and the vehicle can be controlled by means of a set of two signal lines, resulting in a reduction in the amount of equipment.

Abstract: A pickup for an electric string type instrument comprising an elongated piezo-electric member formed by mixing a high molecular material with piezo-electric ceramic powder and a vulcanizing or cross-linking agent and then vulcanizing or cross-linking the mixture. In order to complete the pickup a pair of electrodes are mounted on the elongated member and the member is then subjected to a polarization treatment. The piezo-electric member can be formed as a flat belt-shaped member with the electrodes mounted on both surfaces thereof or it can be formed as a cylinder in which one of the electrodes extends axially in the piezo-electric member and the other electrode is mounted on the outer periphery of the piezo-electric member. A plurality of the pickups can be joined in parallel relation within an elastic support and the latter can be mounted between the strings and the frame of the string instrument through the intermediary of a bridge member.
