Title: Operation control process of power plant utilizing turbine using vaporized organic medium and apparatus therefor
Inventor: SAKAGUCHI HARUICHIROU
IPC: F01K25/10
Filed: 1979-06-22
Abstract: PURPOSE: To achieve a stationery heat-exchange performance and prevent superheating of the org. medium at the cut let of the reheater by regulating preheated extent of an organic medium in the preheater, by controlling the flow rate of hot heat medium.  
     CONSTITUTION: Steam is generated by a turbine driven by the vapour of an org. medium such as "Flon", which is heated by a hot intermediate heat medium 14 introduced into a direct heat exchanger 3 after heating it in an oil heater 2 by a hot waste gas 1. The vapour is led by a pipe 11 to turbine to drive a generator. The organic medium liquefied during the task is fed into a preheater 7 by a pump 9. A flow control valve 17 is disposed adjacent to an exit of an oil pump 8 and a thermometer 15 for liq. organic medium 12 is equipped close to an exit of the preheater 7. The flow control valve 17 is controlled by a thermostat 16 on an output of the thermometer 15, thereby preventing organic medium from being overheated at the exit of the preheater.

Title: Conductive roller and its manufacture
Inventor: HATA KATSUHIKO
IPC: G03G15/08
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce variance in the electric resistance of a conductive elastic layer in a circumference direction by providing specified electric resistance between a rotary shaft and the outer peripheral part of the conductive elastic layer and setting a ratio between the maximum and minimum values of electric resistance in the circumferential direction equal to a fixed value or lower. SOLUTION: Electric resistance between the rotary shaft 12 of a conductive roller 10 and the outer peripheral surface 11 of a conductive elastic layer is regulated to 10<3> to 10<9> Ωcm. This range varies depending on a place for using the conductive roller 10 or the like, but when this is set lower than 10<3> Ωcm, if a large current is supplied to the rotary shaft 12 because of an accident or the like, electricity is passed through the conductive elastic layer to an outer surface to cause an image failure or damage part items, and on the other hand, if electric resistance exceeds 10<9> Ωcm, static electricity generated by friction with an opposite member is charged to the surface of the conductive roller to cause an image failure.  Further, by setting a ratio between the maximum and minimum values of electric resistance in a circumferential direction equal to 10 or lower, an image having no uneven gradation is stably provided.
