    • A differential amplifier has at least two pairs of transistors functioning as current dividing circuits in addition to two other conventionally employed current dividing circuits in this type of amplifier. The signal current components flowing through the two additional current dividing circuits surffer no substantial distortions as do those flowing through the conventional current dividing circuits. The output current of the differential amplifier is a sum of these signal components. Accordingly, the less the proportion of the distorted signal components to the undistorted ones is, the freer the differential amplifier from waveform and high frequency distortion becomes.
    • 除了这种类型的放大器中的另外两个常规使用的分流电路之外,差分放大器还具有至少两对晶体管作为分流电路。 流过两个附加电流分配电路的信号电流分量与流过常规分流电路的信号电流分量没有显着变化。 差分放大器的输出电流是这些信号分量之和。 因此,失真的信号分量对未失真的信号分量的比例越小,差分放大器与波形和高频失真越自由。

    • A pressure sensor device having a temperature sensor includes a pressure sensor, a temperature sensor, a sensor casing for accommodating the pressure sensor and a connector pin for electrically connecting the pressure sensor and an outside circuit, and a port mounted on the sensor casing and having a pressure introduction port for introducing a measuring object to the pressure sensor. The temperature sensor is disposed in the pressure introduction port, and electrically connects to the connector pin through a lead wire. The lead wire with the temperature sensor is supported by a connection portion disposed between the connector pin and the lead wire. The lead wire has a buffer disposed between the lead wire and a part of the pressure introduction port for reducing a vibration of both the temperature sensor and the lead wire.
