Abstract: A three dimensional non-volatile memory structure includes word lines connected to non-volatile memory cells arranged in blocks. A plurality of word line switches are connected to the word lines and one or more sources of voltage. The word line switches are arranged in groups of X word line switches such that each group of X word line switches is positioned in a line under Y blocks of non-volatile memory cells and has a length that is equal to the width of the Y blocks of non-volatile memory cells. To allow closer placement of word line switches that supply different blocks and support the possible large voltage differences between their transistors, word line switches supplying different blocks are formed over a single active region and separated by an intermediate control gate set to be off.

Abstract: A process for producing an article with a label, which comprises attaching, to an article, a heat-sensitive and pressure-sensitive adhesive label having an adhesive layer composed of a pressure-sensitive adhesive composition, which is an aqueous emulsion type composition comprising: (A) a water-soluble resin obtained by neutralizing a resin having an acid value of 1 meq/g or more, with a base, and (B) a polymer having an acid value of 0.6 meq/g or less and a glass transition temperature of −20° C. or lower, obtained by emulsion polymerization of a radical-polymerizable monomer, and which, when made into an aqueous film and dried at a temperature lower than 60° C., becomes a film (1) of two-phase structure wherein particles composed of the component (B) are dispersed in a continuous phase composed of the component (A) and, when the film (1) is heated to a temperature of 60° C.

Abstract: A process for producing spiro-orthocarbonate having glycol unit (2) is described, which comprises reacting a spiro-orthocarbonate having glycol unit (1) which is different from glycol unit (2), with a glycol having glycol unit (2) to release a glycol having glycol unit (1).

Abstract: A method for producing spiro-orthocarbonate compounds is disclosed. The method comprises reacting a cyclic carbonate compound of the following formula with an epoxy compound containing an epoxy group: ##STR1## wherein R is an alkylene group or a substituted alkylene group. The disclosed method makes it easy to commercially produce spiro-orthocarbonate compounds in a one stage reaction. The starting materials can be easily handled without any hygienic difficulties and the method can be carried out without entailing any operational difficulties.

Abstract: Certain new derivatives of 2,6,7-trioxabicyclo[2,2,2]octane are found to undergo cationic ring-opening polymerization with positive expansion in volume or with no substantial change in volume, in contrast with known polymerizable compounds such as epoxides which present considerable shrinkage in volume on polymerization. These new bicyclic orthoester compounds can be prepared in a facile way known per se.

Abstract: A precoated steel sheet and a process for production thereof is provided which comprises coating a resin composition comprising mainly an acryloxyloxy- or methacryloyloxy-terminated polyester on the surface of a steel sheet, said acryloyloxy- or methacryloyloxy-terminated polyester being prepared by reacting a hydroxy-terminated polyester comprising (a) a dicarboxylic acid unit containing about 10 to about 80 mol % of a terephthalic acid unit and (b) dihydric alcohol unit containing about 30 mol % or more of a dihydric alcohol unit containing 3 or more carbon atoms, and having a number average molecular weight of about 400 to about 5,000, with acrylic acid or methacrylic acid, and curing the thus-coated resin composition by irradiating the sheet with an electron beam.

Abstract: A curable composition comprising:(A) at least one spiro-orthoester compound having at least one spiro-orthoester group represented by the formula: [I] ##STR1## wherein n is an integer of 3-5, (B) at least one curing agent selected from the group consisting of organic polybasic acids and their anhydrides,(C) optionally, an epoxy compound having at least one epoxy group, and(D) optionally a cationic polymerization catalyst when the composition comprises ingredient (C).Said composition is small in shrinkage on curing, and provides a cured product of high dimensional accuracy when used as a molding material.

Abstract: A curable urethane material which shows no change in volume on polymerization and curing is prepared from polyisocyanate compound, polyhydroxy compound and a new compound 1-alkyl-4-hydroxymethyl-2,6,7-trioxabicyclo[2,2,2]octane.

Abstract: Novel 2-methylene-1,4,6-trioxaspiro[4,6]undecane has both cationic polymerizability and radical ring-opening polymerizability, and it can be produced by reacting a 2-halomethyl-1,4,6-trioxaspiro[4,6]undecane with an alkali to effect dehydrohalogenation.
