摘要:
In a power generation unit incorporated in a fuel cell system, a mixture fuel with a certain concentration is supplied to an anode, power is generated by electrochemical reaction between the anode and a cathode exposed to air, and a discharge liquid containing an unreacted mixture fuel is discharged from the anode. The power generation unit is connected to a fuel circulation path for circulating the discharge liquid to the anode. If a mixture fuel is low in pressure, a fuel supply unit supplies fuel to the fuel circulation path. The temperature of the power generation unit is controlled in accordance with the concentration or volume of the mixture fuel supplied to the anode.

According to one embodiment, a method of driving a fuel cell device includes calculating a fuel shortage based on a difference between the fuel concentration detected by a concentration sensor element and a predetermined desired fuel concentration, and obtaining an efficiency of electricity generation of an electromotive section based on the temperature of the electromotive section detected by a temperature sensor element and the load current measured by a control section. The method includes calculating a fuel consumption by the electromotive section for electricity generation based on the output of the electromotive section and the obtained electricity generation efficiency, and replenishing by a supply section a mixing tank with an amount of fuel equivalent to the sum of the calculated fuel shortage and the calculated fuel consumption, thereby controlling the concentration of the fuel supplied to the electromotive section.

An improved metal coated textile and its production method where the coating of metal is deposited onto the textile through sputtering process in thickness between 20 to 2000 angstroms, with less than 5% variance in thickness across the entire length and width of the textile with width up to and over 10000 mm and length up to and over 1000 meters. The improved sputtering process utilizes longer cathodes, arrangements of metal target(s), tension controller with tension meter(s), guard(s), cylinder cover(s), and control over the textile while traveling through the chamber. The metal layer deposited is highly adhesive to the textile and is suitable for producing clothing, swim wear, diving suit, tent, cushion, wall paper, curtain, carpet, protective cover, screen window, equipment casing, and various other items. The metal layer confers characteristics such as anti-bacterial, deodorizing, improved metallic appearance and texture, electrical conductivity, heat-shielding, heat retention, and dirt repellency to the textile.

A correction region of an input gamut is set in accordance with the chroma of a specific color point of the input gamut, and a correction region of an output gamut is set in accordance with the chroma of a specific color point of the output gamut. The output gamut is corrected based on the correction region of the output gamut so that the specific color point of the output gamut is mapped on a point on the lightness axis of a color space, and input color data is corrected so that the specific color point of the input gamut is mapped on a point on the lightness axis of the color space. The corrected color data is mapped into the corrected output gamut, and inverse correction of correction of the output gamut is performed to the mapped color data based on the correction region of the output gamut.
