  • Publication number: 20030227369
    Abstract: A rotary sensor with a prolonged service life ensures stable electrical conduction between an intermediate terminal and an electrode even if the components making up the rotary sensor repeatedly expand and contract due to high and low temperatures. In the rotary sensor, an output detection member is constructed of an insulating board having an electrode on its surface, a retaining portion being formed on the insulating board. The intermediate terminal is made of a metal material, and has a pair of mounting portions provided on both ends thereof and a first contact portion and a second contact portion provided between the pair of mounting portions. The intermediate terminal is secured to the retaining portion of the insulating board by the pair of mounting portions such that it sandwiches the insulating board lengthwise. The first contact portion is in resilient contact with the internal pin and the second contact portion is in resilient contact with the electrode.

  • Patent number: 4741140
    Abstract: A masonry wall structure comprising hollow concrete block units laid in courses, wherein each of the block units comprises front and rear panel members and a pair of side panel assemblies which form a gap between adjacent two of the block units. The side panel assemblies are connected to the front and rear panel members by means of reinforcing bars projecting rearwardly and forwardly from the front and rear panel members, respectively, into the gaps on both sides of each block unit, connecting bars projecting forwardly and rearwardly from the side panel assemblies into the gaps, steel wires binding overlapping end portions of the reinforcing and connecting bars together, and a body of cementitious material such as mortar filling the gaps and having completely buried therein those end portions of the bars which are bound together by the steel wires.

  • Patent number: 4626961
    Abstract: A printed circuit board has a terminal area to which the terminal area of a sheet member is electrically connected. The sheet member is bonded to the printed circuit board with a hot-melt adhesive. The layer of the hot-melt adhesive which is formed on the sheet member and does not face the terminal area of the printed circuit board protrudes from the surface of the terminal area of the sheet member. The printed circuit board includes an insulating substrate made from a material containing silicon dioxide. A metal salt that imparts hydrophobicity to the bonded surface of the substrate is added to the layer of the hot-melt adhesive.

  • Patent number: 4225843
    Abstract: A variable attenuator comprises a generally horseshoe-shaped main resistance element, a sliding member movable thereover, and a bypass provided around that portion of the main resistance element adjacent the end portion of the path of said sliding member. The bypass is made of a conductive element or conductive element and a resistance element, the amount of current flowing through said bypass being thereby increased to enable a maximum attenuation.

  • Patent number: 4123742
    Abstract: A variable resistor has an insulating substrate plate, a resistance body formed on the substrate plate and a slider adapted to slide along the resistance body. The resistance body is formed in a winding pattern to provide a larger range of variation of resistance for a given stroke of the slider. The slider has a plurality of contacts adapted for sliding along the resistance body so that at least one of the contacts is kept in contact with the winding resistance body so as to provide a linear change of the output of the resistor.
