Title: Gamma correction method
Inventor: HYODO MANABU
IPC: H04N9/11
Filed: 1994-05-24
Abstract: PURPOSE:To perform an image processing excellent in color reproduction and tone characteristic, capable of performing various gamma corrections by the use of a lockup table. CONSTITUTION:A lookup table 25 storing the gamma correction value according to the tone of an input signal is prepared. By multiplying it with the gamma correction value, a gamma gain extending or compressing the gamma correction value is set. Based on the tone of a digital image signal, which is obtained by picking up the image of an original image, it is read out from the lookup table 25. The gamma correction value and the gamma gain are multiplied by a multiplier 26. The gamma correction value extended or compressed is subtracted or added by an adder 24, performing gamma correction. The gamma correction value stored in the lookup table 25 becomes a single code. Thus, no steady point occurs in the case of extending or compressing the gamma correction value by multiplying the gamma grain on the gamma correction value and an excellent control is performed.

Title: Thow-in surge suppression control system for power circuit breaker
Inventor: ITOU HIROSHI
IPC: H01H33/59
Filed: 1977-09-14
Abstract: PURPOSE: To throw in while coinciding source side voltage phase with load side residual voltage phase, by deciding variable throw-in time allowable for super high voltage power circuit breaker and using the result for performing throw in.  
     CONSTITUTION: When throw-in command signal 8 is applied on super high power circuit breaker (CB) control operation signal 9 is functioned. Its operational time t1 varies with time because throw-in time t2 of CB and leading arc time t3 have values inherent to CB while throw-in condition of CB varies in each allowable range thereby t2 also varies in allowable range. Consequently in order to bring CB main contact 11 into "IN" mode at point A where VS level is same with VL -1  level, throw-in time must be determined from characteristic data inherent to CB to determine throw-in time t2.

Filed: 1992-04-28
Abstract: PURPOSE:To provide a small-loss power converter which balances current that flows into regenerative diodes connected to a regenerative circuit from a snubber circuit of the power converter and which prevents application of overvoltage to a semiconductor device. CONSTITUTION:In a circuit which regenerates stored energy in a regenerative circuit 21 from capacitors 6a-6c of a snubber circuit which are connected in parallel with GTOs 1a-1c which are connected in series through regenerative diodes 5a-5c, the same-polarity terminal of each of the regenerative diodes 5a-5c is connected to one and the same terminal of the regenerative circuit 21. By this, current which flows in the regenerative diodes is balanced and therefore a current load of the regenerative diodes is reduced. Since the same- polarity terminals of the regenerative diodes are connected to one and the same terminal and are installed on one and the same cooling fan, the number of components can be reduced and an overvoltage can be prevented.
