  • Gas turbine combined cycle power plant with distillation unit to distill a light oil fraction
    Patent number: 9284856
    Abstract: The present invention is a gas turbine combined cycle power plant which generates electricity by fueling a gas turbine with crude oil or heavy oil and which is provided with a vacuum distillation unit which distills and extracts a light oil fraction from crude oil or heavy oil by keeping the interior thereof in an environment which lowers a boiling point of crude oil or heavy oil, and the vacuum distillation unit is provided with heaters which heat distillation materials by using low pressure steam and medium pressure steam generated in a gas turbine combined cycle.
    Type: Grant
    Filed: December 18, 2009
    Date of Patent: March 15, 2016
    Assignee: MITSUBISHI HITACHI POWER SYSTEMS, LTD.

  • Cylindrical structural body for use in an image forming apparatus and method of producing the same
    Patent number: 5970294
    Abstract: A cylindrical structural body for use in an image forming apparatus and a method of producing the same are disclosed. The structural includes a cylindrical sleeve and flanges or similar end members respectively affixed to opposite ends of the sleeve. The flanges can be firmly and easily affixed to the sleeve without causing the sleeve to deform. The structural body is therefore low cost and highly accurate.

  • Developing roller of monocomponent developing system
    Patent number: 5244741
    Abstract: A developing roller of monocomponent developing system, in which a low hygroscopic material is used for a dielectric layer, thereby suppressing a change of electric properties of the layer caused by water absorption, that is, a dielectric layer using a low hygroscopic material, namely, a low hygroscopic elastomer or a low hygroscopic polymer is used at an outer surface of a conductive supporting body where, as a concrete example of the elstomer or the polymer, polyethylene, polypropylene, ethylenic copolymer, rigid polyvinyl chloride, fluoro resin, acetal resin or mixtures thereof, or the elastomer or the polymer in which manganese-aluminum magnet, strontium ferrite, barrium ferrite of mixtures thereof is dispersed.
