Title: Device for orientating short-circuit fault of twin-lead type power-transmission line
Inventor: EMURA TOKUO
IPC: H02H3/40
Filed: 1982-10-18
Abstract: PURPOSE:To orientate accurately the distance up to a short-circuited point irrespective of earth system and power supply terminal and load end independently of an earth resistance, a load, a capacity to earth of a bus, etc., by processing the voltage and the current of a local end. CONSTITUTION:The line current of a faulty line has the phase shifted in a phase shifting circuit 20 by the phase angle of the positive-phase impedance of the faulty line. The line current of the adjacent line multiplied by the constant of a transmission line is subtracted from said line current in a subtracting circuit 21, and imaginary components of products between the line voltage of the bus and a conjugate complex of the output of the circuit 21 and between the output of the circuit 20 and the conjugate of the output of the circuit 21 are operated in reactive power operating circuits 22 and 23, and the operation output of the circuit 22 is divided in a dividing circuit 24 by the operation output of the circuit 23. Since the output of the circuit 24 corresponds to the absolute value of the positive-phase impedance from the device installation point to the short- circuited fault point, the distance between both points is orientated.

Title: Fluidized-bed burner
Inventor: NISHIYAMA AKIO
IPC: F23C10/24
Filed: 1986-08-06
Abstract: PURPOSE:To move ashes located at positions far from an ash extracting tube to the vicinity of the ash extracting tube to make it possible to extract the same by a simple construction by disposing an ash transfer nozzle spraying a high pressure injection medium in the vicinity of a combustion air nozzle. CONSTITUTION:A combustion air supply nozzle 22 and an ash transfer nozzle 23 are separately installed and the supply system is divided into two parts. Further, since a part of combustion air is extracted and raised in its pressure and is supplied into a fluidized bed 3 as an ash extracting injection medium, generation of nitrogen oxides or sulfur oxides can be reduced. Further, it is possible to freely select the supply quantity of the ash transfer injection medium and to control the ash extraction amount. Further, by constantly monitoring the temperature and pressure within the bed and pressure the outside bed, the ash sxtracting operation can be automated. Even if the fluidized-bed burner is in operation, the supply amount of the injection medium is changed without changing the air ratio, and hence it is possible to extract coarse granular ashes while securing stable fluidization without increasing NOX and SOX.

Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption without dropping the processing speed. SOLUTION: Image data on an i-th slip 1 is inputted to an image input part 34 and an image processing part 37 executes image processing. A time measuring part 39 measures processing time (t) required for the image processing.
