Abstract: PROBLEM TO BE SOLVED: To uniformly distribute all color areas by performing expression with the direction of a longitudinal axis through the center of an inverse cone on a three- dimensional(3D) space, the hue of an angle within a specified range with the longitudinal axis through the center of the inverse cone as a center and differential value between the maximum and minimum values of a shortest linear component from a circle center to maximum circumferential direction. SOLUTION: While defining the size and differential value of color information as a reference, a 3D inverse conical color space is expressed with a direction V of the longitudinal axis through the center of the inverse cone, hue of an angle θ from 0 deg. to 360 deg. with the longitudinal axis through the center of the inverse cone as a center and differential value between the maximum and minimum values of the shortest linear component from a circle center O to the direction of a maximum circumference C. Then, a coordinate value on that 3D inverse conical color space is transformed from input color information, that coordinate value is divided into areas with any arbitrary prescribed value as a reference and these area divided values and transformed value are compared and mapped with a representative value. Thus, all the color areas can be uniformly distributed.

Filed: 1982-08-24
Abstract: PURPOSE:To compensate the voltage variations caused in the low-load range of a fuel cell by applying voltage induced through a step-up chopper to an inverter in connecting DC electric power supplied from the fuel cell to an AC electric power system through said inverter. CONSTITUTION:Oxygen contained in air as well as a reformed gas principally consisting of hydrogen are supplied to a phosphoric-acid-type fuel cell 2 to cause them to react electrically with each other thereby obtaining a DC output which is then applied to a step-up chopper 32 so as to increase and adjust its voltage to almost an equal level to or a higher level than the no-load voltage of the fuel cell 2 irrespective of its output voltage. Next, the voltage of the step-up chopper 32, after being fed to the input of an inverter 33 and converted into AC voltage, is connected to an electric power system 6 through a transformer 4 and a circuit-breaker 5. Thus, the difference between the no-load voltage and the load voltage of the fuel cell 2 is compensated before the voltage is applied to the inverter 3. As a result, the efficiency can be enhanced by omitting a compensation resistor and the like. Besides, any damage to the inverter 33 can be prevented, and the size of the inverter 33 can be reduced.
