Abstract: An aspect of the present invention relates to a coating composition, which comprises an epoxy group-containing compound, acetylacetonate with iron as a central metal, and acetylacetonate with aluminum as a central metal, wherein the ratio mF of the number of moles of the acetylacetonate with iron as a central metal to the number of moles of epoxy group contained in the epoxy group-containing compound, and the ratio mA of the number of moles of the acetylacetonate with aluminum as a central metal to the number of moles of epoxy group contained in the epoxy group-containing compound satisfy the following conditions: 0.000<mF/mA?1.000 0.0064?(mF+mA)?0.0253.

Abstract: A powder container includes a body and a pair of walls that blocks one longitudinal end of the body and the other longitudinal end of the body. Powder is accommodated within the powder container which is mounted to an apparatus using the powder in a posture where a longitudinal direction of the body is a transverse direction of the apparatus. The powder container has an opening, through which the powder is supplied to the apparatus, formed in a lower position of the body in a posture where the powder container is mounted to the apparatus. The powder container includes a shutter and a shield. The shutter is, prior to mounting the powder container to the apparatus, in a closed location to block the opening and, when the powder container is mounted, is moved along an outer peripheral surface of the body to an opened location to open the opening.

Abstract: One aspect of the present invention relates to an optical article comprising: an optical substrate; a hard coat layer provided directly, or over another layer(s), on the optical substrate; an antireflective layer provided on the hard coat layer; and an antifouling layer provided on the antireflective layer; such that when a friction and wear test is conducted on the surface of the antifouling layer under conditions of a scratching rate of 0.1 mm/s and a load increase rate of 0.15 gf/s with a diamond stylus having a tip diameter of 0.03 mm, the load at which the antireflective layer begins to peel off is greater than 50 gf.

Abstract: A piston includes a disc formed to have an annular shape, a cylindrical skirt portion that projects from an outer peripheral portion of the disc on one end side in an axial direction of the disc, and a passage that is formed in the disc and that is opened on an inner side of the skirt portion. An inner peripheral surface of the skirt portion is a slope that increases its diameter toward a side opposite to the disc.

Abstract: An optical device includes an inorganic light-transmissive base material, a hard coat layer, which is provided on a principal surface of the light-transmissive base material and is harder than the light-transmissive base material, and an organic antireflection layer, which is provided on a principal surface of the hard coat layer and contains an organosilicon compound, an epoxy group-containing organic compound, and hollow silica. The hard coat layer and at least one of the organosilicon compound and the epoxy group-containing organic compound are covalently bonded to each other. The occurrence of a defect in the organic antireflection layer can be prevented. The organic antireflection layer has a higher dust-proof effect than an inorganic antireflection film, and therefore, dirt, dust, etc. hardly adhere thereto.
