Abstract: At the time when displaying moving images using liquid crystal panels and others, there is such a problem that tail streaks occur, and resultantly image degradation is caused. In order to solve this problem, an echo suppression circuit 100 divides a video signal into a pair composed of two successive frames for comparison between these two frames in signal level for the purpose of suppressing an echo phenomenon occurring when a liquid crystal panel 108 displays video signals including moving images. If these two frames are not the same in signal level, the signal is accordingly so corrected as to equalize the signal level of those. Based on the video signals and others corrected by the echo suppression circuit 100, a controller 102 operates the liquid crystal panel with Alternating-Current drive through a source driver 104 and a gate driver 106. As such, the drive voltage used to operate the liquid crystal panel with AC drive is so adjusted as to be balanced between positive and negative.

Abstract: A liquid crystal display device comprises two substrates (111, 134), two electrodes (115, 133) arranged between the substrates (111, 134), a liquid crystal layer (120) disposed between the electrodes (115, 133) and having a retardation when giving a black display, and retardation layers (116, 132) positioned between the liquid crystal layer (120) and the substrates (111, 134). The sum of the retardation value of the liquid crystal layer (120) and the retardation values of the retardation layers (116, 132) is approximately zero for light incident on the substrate (134) when a voltage for giving the black display is applied across the electrodes (115, 133).

Abstract: In a machine tool comprising a column (2) mounted for a horizontal sliding movement, a drive unit (4) mounted on the column for a vertical sliding movement, and a magazine (7) located above the drive unit and mounted on the column for a rotational movement and for a horizontal sliding movement, the magazine is particularly adapted to store a plurality of gang heads (8) and individual tools (9) which may be equipped selectively to the drive unit one by one. The drive unit includes a first clamping device (16) disposed within a spindle (14) thereof and further plural second clamping devices (18) which contributes to clamp each of the heads firmly to the unit so that large-scaled gang heads may be employed.Gang heads and tools may be exchanged quickly between the drive unit and magazine. Portions of workpieces unworkable by large-scaled gang heads may be worked by the individual tools.

Abstract: Delay controllers are provided to delay pulses supplied to a plurality of electro-acoustic transducers.Each controller comprises a delay line provided with a plurality of taps and a switch for selectively changing the taps. There are further provided a measuring circuit for measuring amounts of delay time defined by the respective taps of the delay controllers; a CPU for controlling the operation of the measuring circuit and delay controllers. The CPU causes the measuring circuit to measure the amounts of delay time defined by the respective taps. Where the electro-acoustic transducers are electrically operated in accordance with the result of measurement, data for selecting any of the taps is stored in the RAM after proper compensation.

Abstract: An insulator bushing for high d-c voltage input to be used in an electric precipitator, etc. is designed to internally produce jet flows of sealing gas covering the insulator member. While ingress of dust-laden gas passing through the precipitator into the bushing is thereby prevented thus keeping the interior of the bushing clean, the necessary quantity of sealing gas to be supplied can be economically reduced.
