    • A liquid crystal display device (100) of the present invention has a plurality of pixels (P) which are in a matrix arrangement and includes: a first substrate (1) which includes a pixel electrode (12) which is provided in each pixel; a second substrate (2) which opposes the first substrate; and a vertical alignment liquid crystal layer (3) which is provided between these substrates, wherein light that is incident on the liquid crystal layer is circularly-polarized light, and the liquid crystal layer modulates the circularly-polarized light, thereby realizing display. The pixel electrode includes at least one cruciform trunk portion (12a), a plurality of branch portions (12b) extending from the at least one cruciform trunk portion in a direction of about 45°, and a plurality of slits (12c) provided between the plurality of branch portions. The second substrate includes a plurality of counter electrodes (22) which are electrically independent of each other in each pixel. According to the present invention, in a liquid crystal display device which includes a vertical alignment liquid crystal, the γ shift can be sufficiently reduced, and decrease of the transmittance can be prevented.

    • An apparatus for detecting frequency response of audio signals of left and right channels. The audio signals of the left and right channels are alternately introduced at a predetermined periodic rate with intervals of a predetermined duration between times of signal introduction, the introduced audio signals are detected after being divided into a plurality of frequency band signals by band-pass filters, and one of the detected outputs is in turn relayed selectively. During the above described intervals of predetermined duration, an output end of detection device is grounded and the gain of the band-pass filters are made substantially equal to zero in synchronism with the timing of the grounding.
    • 一种用于检测左右声道的音频信号的频率响应的装置。 左右通道的音频信号以预定的周期速率交替地以信号引入时间间隔预定的时间间隔被引入,所引入的音频信号在通过带通滤波器被分成多个频带信号之后被检测 并且选择性地中继所检测的输出之一。 在上述预定时间间隔期间,检测装置的输出端接地,带通滤波器的增益与接地时间同步地基本上等于零。

    • A multi-stage oil-free screw compressor includes: a suction throttle valve for controlling air intake into the compressor; a piston assembly for operating the suction throttle valve; and a structure for supplying a working pressure to the piston assembly. In order to reduce startup load at the time of startup of the compressor, the suction throttle valve is fully closed while a secondary side of a compressor body is opened to the atmosphere. When a negative pressure and the air pressure, that provide the working pressure, are used for slightly opening the suction throttle valve in order to switch the compressor to a loaded mode after a motor for driving the compressor is accelerated to its top speed, the air pressure is provided by a control pipe line that is defined by the same pipe line that forms a drain pipe line. This permits the control pipe line to be opened to the atmosphere as needed during the startup time. Thus is provided the oil-free screw compressor achieving improved startup reliability.
