  • Publication number: 20090244064
    Abstract: A game system controls a first virtual camera and a second virtual camera in synchronization so that the second virtual camera photographs an object space in a range that cannot be photographed by the first virtual camera due to a limitation range. The game system draws various images in a first drawing area and a second drawing area while controlling the first virtual camera and the second virtual camera in synchronization.

  • Patent number: 6034283
    Abstract: A process for producing a cyclic alcohol by a catalytic hydration reaction of a starting cyclic olefin represented by the following formula (1) and water:C.sub.s H.sub.2s-2-t R.sub.t (1)wherein R is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a phenyl group or a cyclohexyl group; s is an integer of 5 to 12; and t is an integer of 1 to 4, which comprises supplying a part or the whole of a residue left after separation of said cyclic alcohol from an oil phase containing said cyclic alcohol, unreacted cyclic olefin and impurities having a boiling point between the boiling point of said starting cyclic olefin and that of said cyclic alcohol to a distillation column(s), and recycling the unreacted cyclic olefin obtained after removal of said impurities.

  • Patent number: 5973218
    Abstract: A process for producing a cycloolefin by partial hydrogenation of a monocyclic aromatic hydrocarbon with hydrogen in the presence of a ruthenium catalyst, water and a metal sulfate, wherein the hydrogenation is conducted while changing the concentration of the metal sulfate dissolved in an aqueous phase in which the catalyst is present.

  • Patent number: 5969202
    Abstract: A method for producing a cycloolefin and a cycloalkane, which method comprises: a step of hydrogenating a monocyclic aromatic hydrocarbon under an acidic condition in the presence of a catalyst composition, (i) wherein said catalyst composition is a slurry which comprises a ruthenium catalyst, water and zinc sulfate, and which is preserved, prior to being used in said hydrogenation reaction, under a high temperature and high pressure hydrogen atmosphere of from 100 to 200.degree. C. and from 1 to 100 atm for 1 hour or more, and (ii) wherein said hydrogenation reaction is conducted under a controlled pressure, while maintaining a phase separated state of: (a) an oil phase comprising, as main components, the starting materials and the products; and (b) a water phase comprising water as a main component, to thereby control a formation molar ratio of the cycloolefin and the cycloalkane to be formed.

  • Patent number: 5767328
    Abstract: A process for producing a cyclic alcohol which comprises subjecting a cyclic olefin represented by the formula: C.sub.n H.sub.2n-2-m R.sub.m (wherein R represents a hydrogen atom, an alkyl group of 1-4 carbon atoms, a phenyl group or a cyclohexyl group, n represents an integer of 5-12, and m represents an integer of 1-4) to a catalytic hydration reaction with water in the presence of a crystalline aluminosilicate having a primary particle diameter of 0.5 .mu.m or less as a catalyst, extracting the resulting liquid of an oil phase containing a cyclic alcohol and the crystalline aluminosilicate, evaporating the liquid and feeding the vapor to a rectifying column and/or filtering the liquid and feeding the filtrate to the rectifying column, thereby to adjust the concentration of the crystalline aluminosilicate contained in the liquid in the rectifying column to 1000 ppm by weight or less, and subjecting the liquid to distillation to separate the cyclic alcohol.
