摘要： A pressure roller support member that rotatably supports a pressure roller is supported to a fixing unit case so as to be capable of swaying. A spacer member is supported to the pressure roller support member so as to be capable of swaying. A spacer section is formed at an end of the spacer member. When the spacer member sways, the spacer section moves between a first position where the spacer section is clamped between the fixing unit case and the pressure roller support member and a second position where the clamp between the fixing unit case and the pressure roller support member is released.

摘要： A fuel cell system includes a fuel cell having a fuel gas flow path and an oxidant gas flow path; a compressor for supplying humidified air to the oxidant gas flow path; a back-pressure regulating valve for controlling pressure of humidified air in the oxidant gas flow path; a pressure sensor for measuring the pressure of the humidified air in the oxidant gas flow path; and a control section for controlling the compressor and the back-pressure regulating valve. In this system, the pressure of humidified air in the oxidant gas flow path is regulated to become equal or approximate to a target pressure by the back-pressure regulating valve. When the pressure difference between the pressure measured by the pressure sensor and the target pressure is larger than a predetermined pressure difference, the control section corrects operating conditions of the compressor, so that the measured pressure becomes the target pressure.

摘要： There has been such a drawback that it is difficult to accurately estimate the location of mobile station MS in a mobile communication system. To solve the problem, according to the mobile communication system of the present invention, a mobile station and several base station cooperate for estimation. First the base stations BS in which the mobile station is laid and other base stations adjacent thereto each measure the receipt levels of the radio wave radiated by the mobile station to notify the position manage center of the receipt levels. Second the position manage center instructs the mobile station to control the radio wave pursuant to the receipt levels in such a fashion the receipt levels are stabilized; finally. Third each base station measure the distance between the base station and the mobile station based upon the propagation time of the radio wave to inform the position manage center of the distance. Finally, the position manage center estimates the location of the mobile station based upon a point or several points given by the circles defined using the distances.
