Inventor: KAMANAKA YOSHIHIDE
IPC: H02M7/48
Filed: 1992-07-17
Abstract: PURPOSE:To balance three-phase output voltages of an uninterruptible power source to be connected with an unspecified single-phase load. CONSTITUTION:A deviation of a mean value Vdet obtained by simultaneously three-phase rectifying three-phase output voltages from a set value Vset is obtained by a matching circuit 1. Deviations of mean values obtained by individually rectifying three-phase voltages Vu, Vv, Vw by single-phase full-wave rectifiers 5u, 5v, 5w from the value Vset are respectively obtained by matching circuits 6u, 6v, 6w, and both the deviations are added by adders 8u, 8v, 8w. Outputs of the adders 8u, 8v, 8w are multiplied by three-phase reference sine wave signals Su, Sv, Sw having different phases of 120 deg. from each other by multipliers 13u, 13v, 13w, outputs of the multipliers 13u, 13v, 13w are input to a gate logic circuit 4 to obtain gate signals of the phases, and three-phase inverters are individually PWM-operated.

Abstract: PROBLEM TO BE SOLVED: To enable the obtaining of the signal of the transparent image of an object of any form by providing an element array in which a plurality of photoelectric converting elements are one-dimensionally aligned and a plurality of scintillation fibers each connected to the photoelectric converting elements. SOLUTION: This radiation detector comprises an X-ray tube 10 which irradiates an object T with X-rays, a signal processing circuit 11, a calculator 12, a monitor 13, etc., and the ends of scintillation fibers 2 are arranged at a location opposed to the tube 10 and behind the subject T. A portion of the X-rays which comes out from the tube 10 and passes through the subject T enters the ends of the fibers 2 and is converted to light. This light propagates through the fibers to be guided to a photodiode array A and converted to electric signals at every channel. Processing, such as amplification is performed on these signals by a signal processing circuit 11. The processed signals are guided to a calculator 12 and converted to the signals of the transparent image of the subject by suitable data processing, and then displayed on a monitor 13 as an image.

IPC: H01L21/027
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To increase emitting position detection precision in electronic beams and measurement precision in dimensions by a method wherein a focus position is slid and deflection scanning is performed on a position detecting mark with gradated electronic beams, and detection signals from the mark are approximated to a normal distribution function to calculate a mean value and a standard deviation. SOLUTION: A focus position of electronic beams 1 is slid in a vertical direction to a sample and scanning is performed on a mark fixed at the same height as a sample face on a sample stage 21. At this time, any one of a main deflector 13 or a sub-deflector 14 is used, or the both are combined to deflect the electronic beams 1 to scan. Reflection beams generated by scanning on the mark by the electronic beams 1 are detected by a reflection electronic detector 23. Detected signals are converted into degital signals by an analog degital converter 32 with a simplifier 31, and stored in a waveform storage memory. Based on the detected signals stored in the memory 33, a mean value and a standard deviation are calculated by normal distribution approximation calculating means 34. Thus, correction precision of an approach effect correction is enhanced.

IPC: G06F13/00
Filed: 1989-07-24
Abstract: PURPOSE:To correctly recognize the trouble of input/output ports by statistically adding and subtracting trouble conditions of plural input/output ports. CONSTITUTION:A trouble detecting mechanism consists of an error condition detecting mechanism 4, an adding mechanism 5, a subtracting mechanism 6, a counter register 7 where counting is performed and the counted value dependent upon mechanisms 5 and 6 is held, an overflow detecting mechanism 8 which detects whether it exceeds a prescribed threshold or not, and input/outputs 9 and 10 to an error signal line S. If a shared memory has the cause of error, counted values of respective input/output ports are added and subtracted in average and do not exceed the threshold. Thus, the input/output port is prevented from being erroneously decided to be in trouble; and if the input/ output port is abnormal, error frequently occurs in this input/output port and its counted value is added to exceed the prescribed threshold, and trouble of the input/output port is recognized, thereby correct decision is performed.
