Abstract: A paint which can be used in combination with either an aqueous paint or an oil-based paint, and which has a quick-drying property and a slow-curing property may comprise a water-dispersible acryl-modified alkyd resin as an active ingredient. The paint may comprise a water-dispersible acryl-modified alkyd resin and a water-dispersible polymer as active ingredients. The paint may comprise a water-dispersible acryl-modified alkyd resin and a surfactant as active ingredients. The paint may comprise a water-dispersible acryl-modified alkyd resin, a pigment, an extender pigment, a surfactant and water as active ingredients.

Abstract: In a game system, a player can displace direction of a view line disposed in a three-dimensional space coordinate system to change the corresponding perspective-projected image by changing the aim of the gun-type controller, by setting a specific region on a perspective projection plane; detecting a designated position with respect to a display plane, which is designated; determining whether or not the designated position is located in a specific region; displacing the view line direction or moving the view point position based on the positional relationship of the designated position and the specific region when the designated position is not positioned inside the specific region; and finding a two-dimensional image obtained by perspective projection in the new view line direction after the displacement of the view line direction or movement of the view point position and displaying two-dimensional images on the display device.

Abstract: This semiconductor memory device is provided with a plurality of main bit lines; a main bit line controller for controlling whether to impress a specific voltage on the main bit lines, connect the main bit lines to a sense amplifier, or place the main bit lines in the OPEN state, based on an address signal; a plurality of virtual main grounding lines; and a virtual main grounding line controller for controlling whether to impress a specific voltage on the virtual main grounding lines, impress a grounding voltage on the virtual main grounding lines, or place the virtual main grounding lines in the OPEN state, based on an address signal.

Abstract: A plurality of filaments are stretched in parallel on a rear plate, and an insulating plate is provided so as to cover the filaments. In the insulating plate, a plurality of through-holes are formed along the longitudinal direction of the respective filaments for exposing parts thereof. Each through-hole and phosphor layers, which are provided on the insulating layer adjacent to the through-hole, constitute one unit picture element. The respective phosphor layers in the respective picture element are installed in a plurality of cavities formed in a rib provided on a lower surface of the insulating plate, whereby separated from the neighboring phosphor layers. The respective cavities function as a discharge room, with a light-transmissive front plate, formed on the rib, as a lid and a portion of the insulating plate corresponding to the phosphor layer as a bottom. The respective discharge rooms overlap the through-hole at one end in the longitudinal direction thereof.
