Title: Method for driving liquid crystal display device
Inventor: TSUBOTA HIROYOSHI
IPC: G02F1/133
Filed: 1987-05-08
Abstract: PURPOSE:To prevent the generation of unevenness of a contrast by inverting the polarity of a scanning voltage and a lighting/non-lighting voltage in accordance with a polarity inverting signal and applying it to a scanning electrode and a signal electrode. CONSTITUTION:l=3, (k)=2, one scanning line selection time (t), and one frame (one scanning period) T are assumed and first of all, the polarity inversion is executed by the scanning line selection time of (l) pieces, namely, three pieces, and subsequently, the polarity inversion is executed by the scanning line selection time of (k).(l) pieces, namely, six pieces. That is, the duty of the polarity inversion is set to 1:(k), namely, 1:2. However, in case of this state, DC component is left, therefore, by inserting the polarity inversion signal at every scanning line selection time of natural number multiple of (m), the DC portion can be eliminated to some extent. In order to eliminate entirely said portion, it is desirable that the inversion is executed even times at an equal time interval in a period for selecting a scanning line of natural number multiple of the least common multiple of (m) and (1+k).l. In such a way, the variation of a frequency component of a waveform by a display pattern is reduced by a driving waveform, and also, it does not occur that the frequency component becomes extremely high, and the unevenness of a display contrast is disappeared.

Title: Method and device for reducing iron loss of directional electromagnetic steel plate
Inventor: KIMOTO TETSUO
IPC: C21D7/06
Filed: 1981-07-17
Abstract: PURPOSE:To reduce iron loss of directional electromagnetic steel plate remarkably by projecting granular bodies such as metallic grains etc. on the surface of finish annealed directional electromagnetic steel and giving minute dotlike strain linearly. CONSTITUTION:A steel plate 1 is moved in the direction of the arrow. A fixed plate 3 having a slit 2 and a sliding plate 4 having a slit that can reciprocate freely are installed above the pass line of the steel plate keeping a specified distance therefrom. The sliding plate 4 is connected with a sliding device 5 through a piston rod 6. When the sliding plate 4 is reciprocated by the sliding device 5, granular bodies, for instance steel shots, projected from a grain projector 10 directed to the slit 2 of the fixed plate 3 hit the steel plate 1 and give dotlike strain only when the slit 2 of the fixed plate 3 and the slit 2 of the sliding plate 4 are overlapped. Since the slit 2 is provided linearly in the direction of width of the steel plate, dotlike strain on the steel plate is formed linearly.

Abstract: PURPOSE:To increase adhesive power with a monocrystal thin film which is formed through melting and recrystalization on the surface, by a method wherein Si is made in exessive of O near the surface of an Si insulative film. CONSTITUTION:O2 is added to SiH410%+Ar90% in vol. ratio of 200:1 and this is subjected to reaction at temperature ca. 650 deg.C so as to form SiO2 2 with a thickness of ca. 500nm on an Si substrate 1. Then, with O2 being added to SiH4+Ar in vol. ratio of 10<3>:1, SixOy 3 including exessive Si is formed in a thickness of ca. 100nm. After stopping supply of O2, poly-Si 4 of ca. 400nm is developed and Si3N4 5 of ca. 100nm is superimposed thereon. After selectively removing both Si3N4 5 and poly-Si 4, a particle is irradiated to melt and recrystalize the poly-Si 4 so that a region of monocrystal Si is formed. The melted Si has a good wetting perfomance because it locates on the oxide including Si in excessive of 0. Thus, adhesion power of the monocrystal layer with the SixOy film 3 is strengthened and this is very effective in devices of SOI structure.
