Abstract: Disclosed is a water-developable photosensitive resin composition capable of hot melt molding, which comprises:(i) a water soluble or water dispersible polyvinyl alcohol prepared by saponifying a copolymer which is obtained from copolymerizing 0 to 20 mol % of a monomer not having an ionic group (hereinafter referred to as "nonionic monomer"), 0 to 10 mol % of an ionic group-containing monomer (hereinafter referred to as "ionic monomer") and the remaining amount of a vinyl ester in the presence of a thiolic acid wherein the total content of the ionic monomer and nonionic monomer is 0.1 to 20 mol %; said polyvinyl alcohol having a terminal mercapto group, a saponification degree of the vinyl ester unit of 50 to 70 mol %, and a hot melt flow starting temperature of 60.degree. to 130.degree. C.(ii) a polymerizable monomer, and(iii) a photopolymerization initiator.

Abstract: A semiconductor integrated circuit device includes a switch for switching an external clock; a signal generator for generating a power down signal for controlling said switch; said signal generator being responsive to an external signal input designating the status of the output of the microprocessor provided at the periphery of the device and an internal control signal of the device for producing said power down signal in a special combination logic state of said external signal input and said internal control signal; the device being set in a power dissipation reduction mode when said power down signal is generated.

Abstract: A method of production of photopolymer printing plates particularly characterized in the transfer procedure. In the method, an electrostatic latent image of original material is produced on a photoconductive medium, the image is developed by application of toner particles, and the toner image is transferred onto photopolymer printing plates having photosensitive resin layer or containing polymerizable monomer through linear pressure of line contact. The toner image thus transferred is then exposed to light without being fixed, plate portions defined by the toner image being subsequently removed together with the toner particles.
