  • Patent number: 9489100
    Abstract: A plurality of first conductors and a plurality of second conductors disposed in first and second directions crossing with each other are disposed in an opposing relationship to each other and in a spaced relationship by a determined distance from each other, and a variation of a capacitance formed between any of the first conductors and any of the second conductors based on a variation of a distance between the first conductor and the second conductor when one of the first conductor and the second conductor is deflected by pressing by a pointer is detected to detect a position pointed to by the pointer. A spacer is disposed between the first and second conductors in a region of a cross point such that a deflection amount of one of the first conductor and the second conductor by the pressing by the pointer has a value higher in a region other than the region of the cross point than in the region of the cross point at which the first conductor and the second conductor cross and overlap with each other.

  • Publication number: 20160170535
    Abstract: A pointer detection sensor is fabricated in which a plurality of first conductors disposed in a first direction and a plurality of second conductors disposed in a second direction which crosses with the first direction are disposed in an opposed relationship to each other and spaced a distance apart from each other. When one of the first conductors is deflected by pressing by a pointer to vary a distance between the conductor and one of the second conductors, a capacitance formed between the first conductor and the second conductor is varied. Fabrication of the pointer detection sensor includes enclosing an ultraviolet-curable optical elastic resin in a liquid form between the plurality of first conductors and the plurality of second conductors, disposing a mask member, which has a plurality of through-holes, on the plurality of first conductors side or the plurality of second conductors side, and forming spacers by irradiating ultraviolet rays on the ultraviolet-curable optical elastic.

  • Patent number: 4857304
    Abstract: A cosmetic composition comprising at least one fluorocarbon having the formula C.sub.n H.sub.p F.sub.q X.sub.4 wherein X represents chlorine or bromine, n is an integer of 1 to 8, q is an integer of 1 to 18, and p+q+r is an 2n+2, which is liquid at an ambient temperature and has a boiling point of 200.degree. C. or less, in the composition. This cosmetic composition does not exhibit an unpreferable oily feeling finish but does exhibit a cosmetic finish which lasts for a long time.
