Title: Method of driving liquid crystal element
Inventor: TANAKA TAKAAKI
IPC: G02F1/133
Filed: 1988-03-28
Abstract: PURPOSE:To obtain a wide margin and to prevent the decrease of the contrast of the liquid crystal element by preventing the continuous impression of the voltage pulses for selecting the display contents of the liquid crystal element in the same polarity direction within a non-selection period. CONSTITUTION:A 1st voltage pulse the absolute voltage of which is zero value, a 2nd voltage pulse the polarity of which is the same polarity as or reverse polarity from the polarity of the 1st voltage pulse on the scanning electrode according to the selection contents of picture elements and the absolute value of which is below the threshold voltage of the element and is variable and the 3rd voltage pulse which has the polarity reverse from the polarity of the 2nd voltage pulse and has the absolute value equal to the absolute value of the 2nd voltage pulses are impressed onto signal electrodes in synchronization with the 1st-3rd voltage pulses within the selection period. On the other hand, the voltage pulse which has the zero absolute voltage or the absolute value below the threshold voltage of the liquid crystal element is impressed onto the signal electrodes during the non-selection period. The voltage pulses are not continuously impressed at the length of the pulse width or above of the 2nd and 3rd voltage pulses in the same polarity direction. The decrease of the contrast is thereby prevented.

Title: Matrix drive display device
Inventor: SAKAMOTO TSUTOMU
IPC: H04N9/12
Filed: 1987-03-30
Abstract: PURPOSE:To eliminate the need for a color changeover circuit and to prevent generation of flicker and deterioration of liquid crystal by connecting electrodes in column directions to picture elements of the same color at each other row and selecting two adjacent rows sequentially at the same time in selecting a signal write row via a drive electrode of the row direction. CONSTITUTION:Data lines 13B are connected to thin transistor TFT circuit 14B driving each picture element 11B of the same color at each other line and two address lines are connected to each of the TFT circuits 14B. When a gate voltage is outputted to one address line 12B from a Y driver, the TFT 14B above and below the address lines 12B is turned on and a data is written in each liquid crystal. Thus, even when the polarity change by one field each is applied, the application of positive or negative voltage is prevented to even and odd number rows so as to prevent the deterioration in the liquid crystal. Since the data line 13B is connected only to the picture element 11B of the same color, no color changeover is attained and the drive circuit is simplified.

Title: Dry etching and dry etching device
Inventor: KURIHARA KAZUAKI
IPC: H01L21/302
Filed: 1995-03-31
Abstract: PURPOSE: To make it possible to obtain an etching of a pattern of a high aspect ratio and the timewise stable etching rate of the etching by a method wherein gas is excited with plasma, the parameter of ions to reach the desired surface of an etching region of a substrate is controlled with the change in the aspect ratio of the pattern and the pattern is etched. CONSTITUTION: Plasma is formed by applying a high frequency to a cathode 3. Ions and radicals, which are formed here, a plasma application chamber, are made to flow in a measuring chamber 2 by a lead-in electrode 5 through an orifice 4 opened in the cathode 3 and the energy of the ions, the current value of the ions, ionic species and radical species are measured by an energy filter 6 and a mass spectrograph 7. Here, when the aspect ratio of a pattern is changed into a ratio of 20 to 100 or thereabouts, an ionic current is reduced from 30 to 1/100 under the bottom of the orifice. There, as the ionic current from the plasma can be increased by reducing the pressure of gas, a reduction in the ionic current under the bottom of the orifice can be prevented from being generated.
