Title: Cmos output buffer circuit
Inventor: ORITA NOBUYUKI
IPC: H03K19/0948
Filed: 1986-05-06
Abstract: PURPOSE:To attain the check of a short-circuited output terminal by inserting a non-doped nMOS transistor(TR) to a conventional CMOS output buffer circuit. CONSTITUTION:The non-doped nMOS TR 6 whose gate and drain are connected in common is inserted between an output terminal 4 and the power supply side pMOS TR 3 of a CMOS circuit comprising the series connection of an nMOS TR 2 and a pMOS TR 3.

Title: Coal gasification power generating plant
Inventor: KISO FUMIHIKO
IPC: F02C9/28
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To suppress pressure fluctuation of a coal gasification furnace in a small value, and improve controllability of coal and oxygen supplying rate by detecting a value of pressure in the coal gasification furnace, and controlling a pressure regulating valve arranged in an inlet of a gas turbine combustor by a deviation between the pressure value to be detected and a setting value of the coal gasification furnace. SOLUTION: A pressure regulating valve 91 is arranged between a gas purification unit 400 and a gas turbine combustor 512. Pressure in a coal gasification furnace is regulated in such a way that a control rate in a fuel supply system is calculated by a function generator 41 on the basis of a deviation between a pressure detected by a gasification furnace pressure indicator 61 and a gasification furnace pressure setting value 21 and inlet guide vanes of the pressure regulating valve 91 and a gas turbine compressor 511 are controlled by a fuel supply system controller 51. It is thus possible to improve controllability of coal and oxygen supplying rates without generating time delay in the case where the oxygen and the coal are supplied, and without largely fluctuating the supplying rates of the oxygen and the coal since pressure in the gasification furnace is held in a constant level.
