Abstract: To provide a floor coating composition and floor coating composition additive. It is possible to improve the leveling performance, mopping performance, and other properties of a floor coating composition over those obtained with a conventional tributoxyethyl phosphate leveling agent by adding to a floor coating composition 1) a (C7-C10) aliphatic monocarboxylic acid monoester of a diol, or 2) a (C7-C10) aliphatic monocarboxylic acid monoester or diester of a triol.

Abstract: A multiple projection television system is comprised of a plurality of projection units stacked in matrix to form a large television screen. Each of the projection units has a cabinet, a projector provided in the cabinet, and a screen secured to a front portion of the cabinet. A mounting frame is provided in the cabinet for slidably mounting the projector in forward and rearward directions. A back of the cabinet is opened so as to allow removing of the projector from the cabinet. The screen is detachably secured to the cabinet so as to allow removing of the projector from the cabinet.

Abstract: A projection television set includes a body composed of at least two divided upper and lower units, a screen assembly having an integrally formed screen corresponding to the body, and a plurality of bolt and nut assemblies for coupling the divided units together. Each of the upper and lower units has a projector for emitting light rays for forming an image on a screen and a reflector for reflecting the light rays from the projector onto the screen. The projector of the lower unit is arranged below the reflector of the lower unit, and the projector of the upper unit is arranged in an intermediate position between the reflector of the upper unit and the reflector of the lower unit so that setting angles of the two reflectors are different from each other. A screen assembly is mounted on a front face of the body.

Abstract: A projection television set in which a seamless image may be obtained on a screen. A screen plate of a screen assembly is held under a suspended state by a frame in a state wherein the left and right parts are centered in the frame. A cruciform light-shielding frame is mounted on the frame. A light-shielding plate is swingably mounted on a horizontal light-shielding frame of the frame. The position of the light shielding plate is adjusted in response to the vertical movement of a horizontal joint. Also, the horizontal joint line adjusting mechanism is provided independently of a centering mechanism for a vertical joint line.
