    • A semiconductor device of one chip has a first power supply terminal allowing connection with an external power supply IC, a second power supply terminal allowing connection with the external power supply IC, a main voltage dropping circuit connected with the first power supply terminal, a secondary voltage dropping circuit connected with the second power supply terminal, and an internal circuit connected with the main voltage dropping circuit and the secondary voltage dropping circuit. A high voltage of the external power supply IC is received in the main voltage dropping circuit through the first power supply terminal and is dropped. The high or low voltage of the external power supply IC is received in the secondary voltage dropping circuit through the second power supply terminal and is dropped. The internal circuit is operated by using the dropped voltage obtained in the main or secondary voltage dropping circuit.

    • A specimen of thin film of a material having a crystal structure and exhibiting an absorption in ultraviolet region is irradiated with electron beams and the energy loss spectrum of the reflected electrons is observed and utilized. For example, the correlations of (1) the energy of the plasmon peak and the relative intensity of the plasmon peak to the elastic peak or the profile thereof, (2) the energy (loss energy being between 4 and 8 eV) of the peak attributed to &pgr;→&pgr;* transition and the relative intensity of the &pgr;→&pgr;* peak to the elastic peak or the profile thereof and (3) the profile of the background of the continuous spectrum formed by inelastic scattering of electrons or the relative intensity of a point to the elastic peak and the average crystallite size of the material of the specimen are used to determine the crystallite size of the material.

    • An active noise controller includes a prediction filter which includes a delayer for delaying the noise or error detection signal by a predetermined period of time, a first adaptive filter for processing the output of the delayer to deliver its periodic component, and a subtractor for subtracting the output of the first adaptive filter from the noise detection signal to deliver a random component of the signal. More specifically, the prediction filter is capable of dividing the noise or error detection signal into two, periodic and random, components. In addition, two, second and third, adaptive filters are provided for processing the periodic and random components respectively. Accordingly, the second and third adaptive filters become responsive precisely to their respective periodic and random components regardless of the ratio in level between the two components, whereby any undesired noise consisting of the two discrete components will be suppressed.
    • 有源噪声控制器包括预测滤波器,该预测滤波器包括用于将噪声或误差检测信号延迟预定时间段的延迟器,用于处理延迟器的输出以递送其周期性分量的第一自适应滤波器,以及减法器 从噪声检测信号输出第一自适应滤波器以传送信号的随机分量。 更具体地,预测滤波器能够将噪声或误差检测信号分成两个,周期性和随机分量。 另外,提供两个,第二和第三个自适应滤波器用于分别处理周期性和随机分量。 因此,第二和第三自适应滤波器对于它们各自的周期性和随机分量而言都是精确地响应,而与两个分量之间的电平之比无关,由此将抑制由两个分立分量组成的任何不需要的噪声。
