Title: Image display device
IPC: H04N5/68
Filed: 1992-04-03
Abstract: PURPOSE:To increase the brightness without increasing the number of signal modulating electrodes by dividing horizontal deflecting electrodes into upper and lower parts. CONSTITUTION:The horizontal deflecting electrodes 6 and 6' are divided into the upper and lower parts on a screen. The head cathode driving pulse 'a' of the upper side of the screen and the head cathode driving pulse 'd' of the lower side of the screen are opposite in polarity to each other for a 16H (horizontal scanning) period; and a cathode 2a performs emission at LOW level and at this time, a cathode 2d is cut off at HIGH level. Namely, the cathodes 2 turn ON alternately between the upper side and lower side of the screen. Then, the horizontal deflection waveform of the upper side of the screen varies in a period wherein the cathode 2a is at the HIGH level and OFF, and the horizontal deflection waveform of the lower side of the screen varies when the cathode 2a goes down to the LOW level and the cathode 2d goes up to the HIGH level. Therefore, periods for rising and falling in the variation of the horizontal deflection waveforms need not be provided and all the period can be used as a PWM period, so the screen brightness can be increased.

IPC: B05D3/00
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To measure fixedly or precisely a deposition rate without being influenced by a solvent in a coating. SOLUTION: When a solvent-containing coating is applied to a work 1 with a coating gun 3 while it is transferred relatively to the coating gun 3, the coating is applied to a sample sheet 10 during the same relative transfer as that of the work 1 with the coating gun 3. Further, it is dried, and a weight of the dry deposited coating is measured. Besides, a specific amount of the coating discharged from the coating gun 3 is sampled, its dry weight is measured, and a coating deposition rate is obtained based on those measured values.

Abstract: PURPOSE:To reduce the size and cost of an equipment by making the withhold voltage of such devices as an ac contactor and a charging resistor of an initial charging circuit of an electric car which has a PWM converter and a PWM converter small. CONSTITUTION:In an electric car which has a PWM converter 4 and a PWM converter 6, an initial charging circuit is installed which passes the output of an ac supply 1 through a tertiary winding 15 of a transformer whose voltage is lower than that of a secondary winding 3 of a transformer, an ac contactor 17, and a charging resistor 18 and then rectifies it by a diode bridge circuit 19 and charges a smoothing capacitor 5 with the rectified current. When this initial charging circuit intially charges the smoothing capacitor 5, it opens an ac contactor 8 and closes the ac contactor 17 and preliminarily charges the capacitor 5 using the tertiary winding 15 of the transformer as a power supply and after that, it opens the ac contactor 17 and closes the ac contactor 8 and further charges the capacitor through the diode bridge circuit of the PWM converter 4. Even if the ac contactor 8 is closed directly, rush current and overvoltage are small since the smoothing capacitor 5 is preliminarily charged and thereby charging can be done safely.

IPC: H01L21/265
Filed: 1991-04-16
Abstract: PURPOSE:To prevent electrostatic breakdown by implanting ions under a state where resist is removed from the outer periphery of a semiconductor wafer thereby preventing the semiconductor wafer from being charged through ion implantation. CONSTITUTION:In the ion implantation step of semiconductor device fabricating process, ions are implanted under a state where resist 102 is removed from the outer periphery of a semiconductor wafer 101. For example, the semiconductor wafer 101 is coated with the resist 102 which is then exposed and developed in order to form a pattern and to remove the resist from the outer periphery. Thereafter, it is doped with charged ions 104. At that time, the resist 103 is charged because it is an insulator but since the contacting part 107 between a semiconductor wafer fixing part 105 and the semiconductor wafer 101 in the ion implanter is conductive, the charges escape from the semiconductor wafer fixing part 105 which is not thereby charged and protected against electrostatic breakdown.

Inventor: HORI TETSUO
IPC: E02B3/06
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To promote wave prevention efficiency and to reduce a construction cost. SOLUTION: When a bag body 3 is filled with water by operating a plumbing device 8, the bag body 3 is expanded to erect, and the top section hereof is projected to the upper surface of the water together with a fin 7. For that purpose, waves from the open sea are shielded with bag body 3 and fin 7, and calm is maintained in harbors. Since the ends of the bag body 3 are fixed to slopes 1c gradually heightened from the central section 1d of a fixed foundation 1, a rising distance gets along with shortness when the bag body 3 is expanded, and wave prevention efficiency of the bag body 3 is promoted. Since the ends 3a of the bag body 3 are bent along the curves of the slopes 1c and are fixed to the slopes 1c of the fixed foundation 1 in a closely tight state, the fixed width thereof can be equivalent to the fixed width of the central part 3b, and liquid-tightness can be promoted.

IPC: B60H1/08
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent an excessive increase of the load of an engine, in a heating apparatus using a viscous heater. SOLUTION: Screws 5b, 6b, 1b, and 1c are formed to the first and the second plates 5 and 6, and a housing 1, in order to expand the distances δ1 and δ2 , when the both plates 5 and 6 are rotated in the same direction as a rotor 4.
