Abstract: A light dimming dot pattern is provided for an LCD in which the diameter of dots is changed in a range from approximately 0.16 mm to approximately 0.65 mm depending on the distance of the dots from a fluorescent tube (13) in such a manner that the volume of the shielded light is increased and decreased at a location close to a position overlying the fluorescent tube (13) and at a location remote from the fluorescent tube (13), respectively. In this manner, a light dimming dot pattern with a transmittance for all light rays of approximately 62% (roughly in the vicinity of 62%), higher than the transmittance for all light rays in the conventional technique not higher than 50%, is produced. Consequently, the light of uniform high luminance may be produced without raising the luminance of the fluorescent tube (13), and hence an LCD of high luminance may be realized.

Abstract: A noise-reducing device for water vehicles including: a rigid housing having a fluid-tightly sealed chamber formed therein, and fixable to a vibrating part of the water vehicle to be displaced with the vibrating part; a mass member housed in the rigid housing with a given gap therebetween so that the mass member is freely movable in the vibrating direction relative to the rigid housing, the mass member being adapted to come into collision with a contact part of the housing during input of vibration; and an elastic element formed on at least one surface of contact on the contact part or mass member.

Abstract: A charging roll which is held in rolling contact with a photosensitive drum for charging the photosensitive drum. The charging roll includes an outermost layer formed of a resin composition containing a grafted carbon as an electrically conductive agent. The grafted carbon includes a carbon black and a polymer which is grafted on the carbon black so as to cover a surface of the carbon black.
