Abstract: After any cell area to be an always displayed area of an edition area composed of rows and columns of cells is designated, and a scroll display operation is performed, a CPU performs a normal scroll display until the always displayed area reaches an edge of the edition area, at which time the CPU scrolls and displays only an area excluding the always displayed area to thereby refer to cells efficiently even when a table whose size cannot be displayed on a single display screen is edited.

Abstract: A non-volatile semiconductor storage apparatus which incorporates second bit lines connected to the sources of memory cell transistors arranged in a column direction, formed separately from the layer of first bit lines connected to the drains of the memory cell transistors arranged in a column direction. The apparatus is equipped with a system which can erase data byte by byte without enlarging the whole size irrespective of the provision of decoders in the first and second bit lines. A non-volatile semiconductor storage apparatus which erases data byte by byte by selecting a predetermined group of memory cell transistors by the source lines and the word lines connected to the diffusion area in the groups of memory cell transistors.

Abstract: The present invention relates to a hydroxyphenyl-functional polyorganosiloxane compound having the formula ##STR1## wherein R is independently a monovalent hydrocarbon group free of aliphatic unsaturation, A is a substituted or unsubstituted hydroxyphenyl group, B is selected from the group consisting of alkyleneoxyalkylene groups having at least two carbon atoms and alkylene groups having at least 2 carbon atoms, m is zero or 1, and n is an integer from 0 to 400. The hydroxyphenyl-functional polyorganosiloxanes of this invention are useful as surfactants or as additives for organic polymers.

Abstract: There is disclosed a thermoplastic resin composition wherein the dispersion of a polyorganosiloxane in a thermoplastic resin is improved by the inclusion of a copolymer of an organosiloxane compound and an ester of a vinylcarboxylic acid or a copolymer of an aromatic vinyl compound, an unsaturated aliphatic nitrile compound and an organosiloxane compound. As a consequence of the excellent dispersion, the composition has improved moldability compared with conventional thermoplastic resins containing only polyorganosiloxane and yields moldings that have a releasability, lubricity, water repellency and mechanical strength superior to moldings from the conventional thermoplastic resins containing only polyorganosiloxane.

Abstract: A compound rolling guide unit in which a plurality of sliders are saddled on a track rail, in each of longitudinal surfaces of which raceway grooves are formed, in such a manner that the sliders can be slid relatively to the track rail, is provided with raceway grooves in each longitudinal surface of the track rail, a plurality of sliders being saddled on each surface of the single track rail so that the sliders are slid relatively to the track rail. The sliders can be slid independently of each other in the longitudinal direction of and relatively to the track rail.

Abstract: The supply of fluid to a nozzle is interrupted by stopping the supply of fluid by providing a fluid leakage prevention device, that is opened by fluid supply pressure, inside a fluid feed hole possessed by a housing that holds a sphere integrated into a single unit with a tube member (nozzle) while allowing said sphere to rotate.

Abstract: A multi-slider single rail linear motion rolling contact guide unit is provided. The guide unit includes an elongated rail provided with a first pair of guide grooves and a second pair of guide grooves. A first slider is provided with a first pair of endless circulating paths filled with a plurality of rolling members engageable with the first pair of guide grooves, and, similarly, a second slider is provided with a second pair of endless circulating paths filled with a plurality of rolling members engageable with the second pair of guide grooves. Thus, the first and second sliders are slidably mounted on the rail independently from each other.

Abstract: A linear motion guide unit generally includes a rail, a slider, a plurality of rollers provided in a roller guide channel defined between the rail and the slider and a plurality of balls provided in a ball guide channel defined between the rail and the slider. The roller guide channel is defined between an inner inclined guide surface formed at a shoulder of the rail and an outer inclined guide surface formed in the slider and the ball guide channel is defined between an inner guide groove having a Gothic arch-shaped cross section and an outer guide groove having also a Gothic arch-shaped cross section.

Abstract: A double linear motion guide unit assembly includes a pair of first and second rails extending in parallel, a pair of first and second sliders which are slidably mounted on the first and second rails, respectively, a plurality of first rolling members interposed between the first rail and the first slider, a plurality of second rolling members interposed between the second rail and the second slider, and a sliding table commonly mounted on the first and second sliders as fixedly attached thereto. A Gothic arch shaped inner guide groove is formed in the first rail at each of its sides surfaces and a similarly shaped outer guide groove is formed in the first slider and a circular arc shaped inner guide groove is formed in the second rail at each of its shoulders and a similarly shaped outer guide groove is formed in the second slider.

Abstract: A method for removing carbon scale, comprising permeating carbonate or bicarbonate into the carbon scale formed on a metal surface of a heating furnace, reactor or the like in a chemical plant by bringing the former into contact with the latter and decomposing the thus treated scale through oxidation by applying heat.
