Title: Method and device for driving liquid crystal display device
Inventor: YAMAGUCHI HISASHI
IPC: G02F1/133
Filed: 1988-12-29
Abstract: PURPOSE:To suppress the generation of a brightness irregularity by comparing the logic state of a liquid crystal cell on a selected scanning electrode with the logical state of the liquid crystal cell right before it, generating and putting differential pulses together with the opposite polarities into a voltage for off display to a scan driver, and canceling the differential pulses induced at the scan electrode when a voltage is applied to a data electrode. CONSTITUTION:A simple matrix type liquid crystal panel 3 is equipped with a data driver 1 and the scan driver 2. Data displayed on a selected scan electrode every time one line is selected is compared with data on the last selected scan electrode to find the difference between the number of times of variation from off display (logic 0) to on display (logic 1) and the number of times of variation from the on display (logic 1) to the off display (logic 0) in, for example, a positive voltage application mode period, thereby obtaining differential pulses corresponding to the difference. The differential pulses are put together with the opposite polarities into the off display voltage to the scan driver 2 of a power circuit 4 to cancel differential pulses induced on the scan electrode side. Consequently, the generation of the irregularity in brightness is suppressed completely.

Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To print high density, precise and highly integrated bumps or the like and to further narrow the bumps or the like by preprinting, and dividing one printing into several times. SOLUTION: An overall pattern pads of a matter to be printed are printed at one time, the pad 6 is previously printed, and the pad 7 is printed thereafter. An interval between the pads is set to about 250 μm or below, and a diameter of the pad is set to about 100 μm or below. A length of the pattern is free, an interval between the pads and a width of the pattern and an enlarging direction of a diameter of the pad can be freely set.

Filed: 1992-12-11
Abstract: PURPOSE:To apply stable dampness to shaft vibration and improve the control performance with a rotor supported in no contact by fixing a permanent magnet to the rotor, forming the magnetic path with magnetic substances having a gap, and inserting a stationary conductor in the gap. CONSTITUTION:A nonmagnetic sleeve 1 is fitted to the end face of a rotor 20, and a permanent magnet 3 is carried by it. The N side and S side of the permanent magnet 3 are pinched by magnetic disks 4a, 4b to constitute a magnetic path, and a gap is formed at part of the path. A doughnut disk of a conductor 2 is inserted into the gap portion. When the shaft vibration of the rotor 20 occurs, the disks 4a, 4b fixed to the rotor end section are vibrated in the direction perpendicular to the rotor shaft, the magnetic field in the gap is relatively moved against the conductor 2, an eddy current is generated in the conductor 2, and damping force is generated. This damping force serves to prevent the oscillation of a control system, the gain range where no oscillation occurs in the high-order mode is widened by the tuning of the control system, and the control characteristic can be improved.

Inventor: ITO KOICHI
IPC: A01N59/16
Filed: 1994-12-12
Abstract: PURPOSE: To obtain a uneluting antimicrobial member exhibiting excellent antimicrobial and antifungal action over a long period. CONSTITUTION: TiO2 , Ag, an element of platinum groups, etc., are evaporated onto the surface of a substrate such as a metal, a coating film, a plastic, a rubber, ceramics or a fiber while irradiating with ion beam to form an Ag deposited film and TiO2 film and/or a film of platinum groups.

Title: Modulation system
Inventor: TOMITA HIDEHO
IPC: H04L27/20
Filed: 1987-12-29
Abstract: PURPOSE:To obtain a transmission output similar to an orthogonal modulation output and to preclude nonlinear distortion generated by a power amplifier by making the drive level of the power amplifier constant and thus preventing AM/PM conversion by the power amplifier, and bringing the amplitude of the output of the power amplifier under feedback control. CONSTITUTION:An orthogonal modulator 10 imposes orthogonal modulation upon the output of an oscillator 1 with a couple of base-band input signals. The orthogonally-modulated signal has an amplitude component and a phase component, but has its amplitude made constant through a limiter 2 so as to preclude the AM/PM conversion by the power amplifier 4. The output of the limiter 2 is amplified by the power amplifier 4 up to a necessary level and inputted to a level controller 5. A level detector 3, on the other hand, detects the amplitude component of the orthogonally- modulated output and inputs it to a subtracter 6. Further, a level detector 11 detects the amplitude of the transmission output and inputs it to the subtracter 6. The subtracter 6 detects their difference and inputs it the level controller 5 as a difference signal. The difference signal is inputted to the level controller 5 and brought under feedback control by constituting closed loop, thereby controlling the amplitude of the transmission output to the output of the orthogonal modulator 10.
