Abstract: Disclosed is a photosensitive resin plate which effectively prevents dot gain by covering the photosensitive resin layer with a specific matte layer. The photosensitive resin plate comprises a substrate, a photosensitive resin layer formed on the substrate and a resin matte layer formed on the photosensitive resin layer, wherein the resin matte layer contains a polymerization inhibiting material.

Abstract: An apparatus and method for controlling clusters having processors constituting a multiprocessor system. The apparatus includes a global control unit for processing orders between clusters and a memory control unit, provided in each cluster, for controlling transmission and reception of orders between the global control unit and the processors. Commands from one processor to another processor are sent to the memory control unit of the cluster containing the other processor and not directly to the other processor.

Abstract: In a computer system having at least a main storage unit and a memory control unit, a storage control system accesses two memory areas provided in the main storage unit, each of the two memory areas storing the same information. A double-writing device is provided in the memory control unit for writing the same information to each of the two memory areas by determining the state of a double-writing bit (D-bit) contained in an address order from a processor or the state of a storage configuration bit (F/S-bit) sent from the processor.

Abstract: A vibration wave motor in which a signal for suppressing unnecessary vibration engendered during the driving of the vibration wave motor, besides the driving signal of the motor, is applied to the motor to suppress the unnecessary vibration.

Abstract: A process for producing a silver halide photographic material that has at least one silver halide emulsion layer on a support, in which process at least 10 mg of a calcium salt per mole of silver halide is added during the period from the completion of physical ripening a silver halide emulsion to the completion of its chemical ripening together with at least one compound represented by the following general formula (I) and at least one compound represented by the following general formula (II): ##STR1## where R.sub.1 is a hydrogen atom or an alkyl group; R.sub.2 and R.sub.3 which may be the same or different are each a substituted or unsubstituted alkyl group; A.sub.1 -A.sub.6 are each a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom or a phenyl group, provided that adjacent atoms or groups may combine to form a ring; X is an anion; and n is 0 or 1, provided that n =0 when an intramolecular salt is formed; ##STR2## wherein Z.sub.

The present invention also provides a resin plate for flexographic printing obtained from the above mentioned resin composition and a process for preparing it. The present invention further provides a printing plate obtained from the resin plate and a process for preparing it.

Abstract: A process for preparing a monodisperse core/shell type silver halide photographic emulsion comprising silver halide grains wherein the average silver iodide content in the grains is 0.5 to 10 mole % and each of the grains comprises a core portion having no silver iodide. The silver halide grains are caused to grow from seed crystals having substantially no twin crystal by supplying silver ions and halide ions in the presence of protective colloid. The supplying speeds of silver ions and halide ions are gradually increased as the grains grow and the supply of iodide ions in the halide ions is made before the completion of supply of silver ions. The content of ammonia contained in liquid phase emulsion is fixed to the value that is 0.3 normal or more and pAg is fixed to the value that is less than 8 for the supply of iodide ions.
