Title: Liquid crystal display device
Inventor: KUDO YASUYUKI
IPC: G09G3/36
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device which has its rise in cost suppressed on the whole and has small display unevenness by generating correction data from display data in a display period and applying a correcting voltage in a blanking period. SOLUTION: If voltages applied to data electrodes Xa to Xc vary with the electrostatic capacity of a liquid crystal cell itself and the resistance component between both the electrodes, the applied voltages themselves have waveform rounding and when the data electrodes Xa to Xc are different in the cumulative quantity of waveform rounding, the difference is displayed as display unevenness, i.e., shadowing on the liquid crystal panel. Then, one frame period wherein on picture is displayed is divided into an effective display period and an ineffective display period (blanking period); and the numbers of changes of the data electrode applied voltages are accumulated in the effective display period for each data electrodes and correcting voltages are applied to the data electrodes in the blanking period according to the results to improve the shadowing. Vertical shadowing can be reduced without adding any dedicated correcting power circuit.

Title: Method of detecting end of printer paper
Inventor: YAJI MASAO
IPC: B41J29/48
Filed: 1993-04-28
Abstract: PURPOSE:To remove the malfunction of printer by a method wherein the end of paper is detected by obtaining the difference between first outputted voltage under the state, in which the paper is not set, and second outputted voltage under the state, during which the paper is sucked in, larger than the set value. CONSTITUTION:First outputted voltage VA detected under the state, in which a paper is not set, of a reflection type photosensor 16 is read in and written in the internal register in a CPU 11. Next, the CPU 11 starts to suck the paper and accesses to an A/D converter every rotation by one pulse of a pulse motor line feed action 32 so as to read second outputted voltage VB detected under the state, in which the paper is not set, of the reflection type photosensor 16 and write the internal register in the CPU 11. Then, VA--VB=DELTAV is compared with the set value (d). When DELTAV<=d, the end of the paper is judged so as not to be detected, resulting in rotating the pulse motor for line feed action 32 further by one pulse. When DELTAV>d, the end of the paper is judged to be detected.

IPC: C23C14/35
Filed: 1988-04-25
Abstract: PURPOSE:To continuously perform the cleaning of a substrate and the vapor deposition of a film in the same atmosphere by impressing a negative voltage on the target side and also impressing a negative voltage lower than that applied to the target side on the substrate side to clean the substrate surface and then raising the negative voltage at the substrate side to a value higher than the negative voltage on the target side to carry out sputtering. CONSTITUTION:A substrate 6 is set in a vacuum chamber 1, and the inside of the chamber 1 is evacuated and an inert gas is introduced, by which the pressure inside the chamber 1 is adjusted to the pressure condition (e.g., about 10<-3>Torr) at the time of film-forming operation. Subsequently, a negative voltage is applied to the target 4 side by means of an electric power source 8 for film formation to initiate glow discharge, and a negative voltage lower in electric potential than the negative voltage applied to the target 4 side is impressed on the substrate 6 side to clean the substrate 6 surface. After this electric discharge cleaning is completed, the electric potential of negative voltage is regulated so that it is higher at the substrate 6 side than at the target 4 side and then sputtering is exerted, by which a film is formed on the substrate 6. By this method, sufficient cleaning effects can be produced and also stable thin film formation can be carried out.
