    摘要： Variable operating currents are generated in relation to input signal power and output signal power and achieving both low noise and low power consumption. Emitter follower circuits are attached to output terminals of a frequency divider for generating a local signal. By adjusting the currents flowing through the emitter follower circuits, the amounts of currents flowing into mixers is adjusted. When the amounts of currents of local signals flowing into the mixers increases, the effect of noise suppression is expected. The amounts of the currents flowing through the emitter follower circuits is changed depending on the amplification factor of variable amplifiers.

    摘要： A high-frequency power amplifier which can reduce a variation of power gain due to the dependence on gate length of a power amplification field effect transistor is provided. The high-frequency power amplifier comprises, over a semiconductor chip, a bias control circuit, a bias transistor and an amplification transistor which are coupled so as to configure a current mirror circuit, and a gate length monitor circuit comprising a replicating transistor. The amplification transistor amplifies an RF signal and a bias current of the bias control circuit is supplied to the bias transistor. The transistors are fabricated by the same semiconductor manufacturing process, and have the same variation of gate length. The gate length monitor circuit generates a detection voltage depending on the gate length. According to the detection voltage, the bias control circuit controls the bias current, thereby compensating the gate length dependence of transconductance of the amplification transistor.

    摘要： A chlorine analyzing apparatus includes a reaction tube of a double tube structure with an inner tube for receiving a sample and an outer tube for recovering hydrogen chloride. An electric furnace has a reaction tube insertion hole into which the reaction tube is inserted. The electric furnace is equipped with a heater disposed around the reaction tube insertion hole. A titration cell receives acetic acid as an electrolyte and subjects hydrogen chloride withdrawn from the reaction tube to coulometric titration. A deodorization tube is disposed on a rear stage side of the titration cell for thermally decomposing a vapor of acetic acid discharged from the titration cell. The deodorization tube is fitted into the electric furnace.
