  • Patent number: 7762203
    Abstract: An embroidery 202 is formed by sewing a polarizing fiber onto a suitable cloth 201. The polarizing fiber is composed of a polymer to which a polarization developing material is added and which is stretched after spinning. The embroidery 202 has seams arranged in a predetermined direction. The polarizing fiber exhibits different optical characteristics for a linearly polarized light having an electric field component in the stretched direction of the polymer (the extending direction of the fiber) and for a linearly polarized light having an electric field component perpendicular to that of the above linearly polarized light. Therefore, when a discrimination medium 200 is viewed through a polarization plate, the appearance of the embroidery 202 changes depending on the direction (rotation position) of the polarization plate, so that a discriminating function can be obtained.

  • Publication number: 20090023513
    Abstract: An iron golf club for enhancing the gear effect and accelerating backspin of a ball. The head, which comprises a face part having a ball-hitting surface, a sole part having a ground-contact plane in the bottom portion of the head, a top part, and a hosel part, is configured such that the rigidity on the ground-contact plane side of the bottom portion is lowered by either providing the portion with a cavity or changing its material. Further, the vertical moment of inertia of the head is reduced by disposing a weight in the location of the center of gravity of the head. When the length of the hosel part is 50 mm or longer, the value of the moment of inertia becomes less than 800 g·cm2, and when the length of the hosel part is less than 50 mm, the value of the moment of inertia becomes 750 g·cm2 or less. These configurations realize a golf club that enhances the gear effect and accelerates spin of a ball.

  • Patent number: 6812894
    Abstract: A dielectric chip antenna includes a substantially rectangular parallelepiped dielectric substrate, a feeding electrode, a fixation electrode, and two radiation electrodes. The feeding electrode is provided on one longitudinal end surface of the substrate, and is used to receive high frequency energy to be transmitted. The fixation electrode is provided on the opposite longitudinal end surface of the substrate and is used for fixation of the antenna to a printed circuit board. The two radiation electrodes are formed on a peripheral surface of the substrate so as to extend longitudinally while spirally surrounding the substrate. The base ends of the radiation electrodes are connected to the feeding electrode. The two radiation electrodes are formed symmetrically with respect to a horizontal plane passing through a center axis of the substrate so that the two radiation electrodes are of identical patterns on the upper and lower surfaces of the substrate.
