Title: Liquid crystal display device
Inventor: KOBAYASHI IKUNORI
IPC: G02F1/1368
Filed: 1990-05-17
Abstract: PURPOSE:To project an image having a large-capacity picture element without making the scale of a circuit large by supplying an identical image signal to a display electrode from a thin film transistor (TFT) selected and driven by the line wiring of every two adjacent lines in an identical horizontal scanning period. CONSTITUTION:The drain electrodes of two or more TFTs are connected to one of the display electrodes and the gate electrodes of the respective TFTs are respectively connected to two adjacent line wirings, then a source electrode is provided with a 1st substrate connected to a common column wiring and a 2nd substrate where a counterelectrode is formed. In the identical horizontal scanning period, the identical image signal is supplied to the display electrode from the TFT selected and driven by the line wiring of every two adjacent lines so as to drive liquid crystal display to display the image. Therefore, it is unnecessary to make the frequency of the image signal high because the line wiring is increased, and it will suffice, to make the frequency of the image signal high by as much as the increase of the row wiring. Thus, the image of the large-capacity is projected without making the circuit complicated.

Abstract: PURPOSE:To remove irregularity in density by a method wherein a difference in voltage value between respective blocks of a thermal head resistor is detected and corrected. CONSTITUTION:Output voltage of a transistor 3 is divided by resistor 6, 7, 8.

Filed: 1984-06-22
Abstract: PURPOSE:To suit the thin film to miniaturization and decrease in temperature of semiconductors by forming the thin film with varying the ratio of nitrogen to silicon continuously or gradually from silicon to silicon nitride stoichiometrically. CONSTITUTION:The condition for forming typical silicon nitride, for example, is 700-800 deg.C SiH2Cl2 30-80SCCM, NH3 300-1,000SCCM and the deposition rate is 20-40Angstrom /min.

At last, a perfect silicon nitride is formed and a film thickness only of silicon nitride is endurable for oxidation by a LOCOS method sufficiently. Accordingly, the total film thickness becomes thicker than the conventional silicon nitride film thickness, but the thickness for a silicon oxide film to be formed as a base is not necessary so that the thickness is nearly same.

Abstract: PURPOSE: To change the energy of wave motion into a large quantity of electricity at an optional place on the sea or the like, by causing relative vertical movement between magnets and coils by the vertical motion of wave on the sea or the like.  
     CONSTITUTION: The shafts 2 of electricity generators 1 coupled to floats 9 are reciprocated by the vertical motion of wave or the like so that magnetic lines of force extending from a plurality of annular magnets 3 fitted on the shafts 2 and sandwiched with annular yokes 4 are caused by the yokes to frequency intersect coils 7 or cores 6. As a result, an electromotive force 6 is caused in each coil 7 in a direction according to Fleming's right-hand rule. The direction of the electromotive force depends on that of the reciprocation. The coils 7 are so connected to one another that the electromotive forces are added to one another. Therefore, a voltage which appears between output terminals can be supplied as high electric power to a load.
