  • Patent number: 8193899
    Abstract: A chip-like electric component such as a chip resistor is provided, which is easy to manufacture and in which cracks or fractures of an insulating substrate are unlikely to occur. A pair of surface electrodes 21, 23 are formed so that thicknesses of the pair of surface electrodes increase from a resistor layer 13 toward end portions 30 of an insulating substrate 29 in a direction in which the pair of surface electrodes 21, 23 are arranged. A plating reservoir S is formed between one of the surface electrodes 21, 23 and an insulating protective layer 15. When forming at least one plated layer 33, a plated metal pools in the plating reservoir S. The at least one plated layer 33 may work to reduce to some extent a height difference between a soldering electrode portion 21, 23, 27, 33 and the insulating protective layer 15.

  • Patent number: 8173254
    Abstract: This invention is polyester fibers with an initial tensile resistivity of 15 to 38 cN/dtex, a elastic recovery rate of 70% or more after 20% elongation, and a self-shrinkage percentage of 0.3% to 1.4% after dry heat treatment at 160° C. The polyester fibers of this invention can be used to obtain a woven or knitted fabric resistant against repeated loads, excellent in surface softness and uniformity, and free from projections/recesses and curling. Since the woven or knitted fabric obtained from the polyester fibers of this invention are highly resistant against repeated loads, it can be suitably used as a car seat loaded with human bodies.

  • Patent number: 8131154
    Abstract: A visible light communication apparatus is constituted with a transmitter for illuminating and projecting visible light on which an information signal is superimposed from a lamp fitting and a receiver for receiving the visible light to take out the information signal superimposed on the visible light. The transmitter modulates a transmission information signal, driving a light projecting element of the lamp fitting so as to superimpose the transmission information signal on the visible light of the lamp fitting, thereby radiating white light containing a blue light component as visible illumination light. The receiver receives the white visible light containing the blue light component radiated from the transmitter and generates a receiving information signal from the light receiving signal on a receiving circuit. A blue light photodiode which receives blue light at the highest sensitivity to output a light receiving signal is used as a light receiving element of the light receiving unit.

  • Patent number: 7767911
    Abstract: A grommet (1) has a central shaft (2)through which a wire harness (5) is inserted. A circular connection portion (31) is provided continuously to the periphery of the central shaft(2.) A convex cross-sectionally V-shaped ring-like lip (32) is extensibly provided to the circular connection portion (31) in the direction of the center of the central shaft. A flange portion (33) is provided continuously to the lip portion (32.) When the grommet (1) is assembled to a body panel (10,) the lip (32) of the grommet (1) is extended in the direction of the center of the central shaft (2) of the grommet (1,) thereby reducing the diameter of the lip (32.) Then, the lip(32) is inserted into the through hole (12) of the body panel (10.) Thus, a low insertion force is sufficient when the grommet is inserted thereinto. Consequently, the assemblability of the grommet (1)is enhanced.
