摘要： The present invention makes it possible to remove an organic solvent in an electrode paste and fix an ion-conductive component while maintaining a desired moisture content. Specifically, a sheet of carbon paper applied with the electrode paste is horizontally held in a tank which comprises a drying apparatus. Water in the tank is brought to the boil by the aid of a first heater. Accordingly, the organic solvent in the electrode paste is removed, and the ion-conductive component is fixed, while forcedly humidifying the carbon paper and the electrode paste with steam.

摘要： A high frequency circuit and a high frequency module are provided, in which the accuracy of compensation operation is improved in compensating by digital control. The amplification gain of an amplification element of an amplifier unit is controlled by a bias current of a bias control unit. A process monitoring circuit of a calibration circuit includes a first and a second element characteristic detector and a voltage comparator. The detectors convert the current of replica elements into a first and a second detection voltage. The voltage comparator compares a first and a second detection voltage and supplies a comparison output signal to a search control unit. Responding to the comparison output signal of the comparator and a clock signal of a clock generating unit, the controller generates a multi-bit digital compensation value according to a predetermined search algorithm, and the bias control unit of the second detector is feedback-controlled.
