Abstract: A color sensing device (8) includes: a light source (6) that shines white light to a measurement target object (3); a color sensor (5) that receives the light reflected from the measurement target object to output an R (red) component sensed value, a G (green) component sensed value, and a B (blue) component sensed value each with a first predetermined number of bits; and a converter (7) that converts the R, G, and B component sensed values output from the color sensor respectively into sensed values each with a second predetermined number of bits smaller than the first predetermined number of bits based on the respective maximum values of R, G, and B component measured values measured in advance by a color sensor with respect to a plurality of kinds of measurement target objects.

Abstract: A tube for integrated circuits, which comprises:an electrically conductive substrate sheet formed by laminating an electrically conductive thin layer onto at least one side of a transparent sheet of a synthetic resin, said substrate sheet being bent plural times in a parallel fashion to thereby form an upper section, left and right sections depending therefrom, left and right bottom sections and left and right upright sections spaced away from each other;a covering member formed of left and right resting pieces for resting an integrated circuit thereon; andan electrically conductive band-like lining sheet formed by laminating an electrically conductive thin layer onto at least one side of a transparent band-like sheet of a synthetic resin;said lining sheet being fixedly bonded at both side edges to the lower faces of said resting pieces.

Abstract: This invention provides an electrical conductive foam bead comprising a foamed bead core of a thermoplastic synthetic resin at least partially covered on the surface thereof with an electrical conductive layer, and a molded electrical conductive foamed article comprising a plurality of particulate bodies formed by mutually fusing such electrical conductive foam beads, the electrical conductive layers extending over all or a portion of the interface of the mutually fused particulate bodies. The conductive foam beads and molded conductive foamed articles both have improved antistatic effect and are used as packaging and cushioning materials, electromagnetic radiation shields, and the like.

Abstract: A tube assembly for integrated circuits, wherein a transparent conductive layer is applied to at least one side of a transparent cylindrical member formed of a synthetic resin, a rail member formed of a conductive synthetic resin and including an upper flat portion is inserted through, and comes in close contact with, the said cylindrical member in such a manner that it is movable only in the lengthwise direction of the said cylindrical member, and two grooves are formed in the said upper flat portion along the full length of the said rail member, in the lengthwise direction of said rail member, through which grooves both terminals of the said circuits are slidingly inserted in the lengthwise direction of the said rail member.
