Title: Liquid crystal display device
Inventor: TANABE EIZO
IPC: G09G3/36
Filed: 1985-12-28
Abstract: PURPOSE:To obtain a homogeneous image by providing a memory where picture signals to be displayed on liquid crystal picture elements on a matrix of scanning lines and signal lines are stored and switching the scanning direction at intervals of a prescribed time to output corresponding picture signals from the memory to an output line. CONSTITUTION:A picture signal line driver 9 drives signal lines 8 in accordance with the signal from a memory 10 where one-field components of picture information are stored. A frequency divider 13 sends a control signal to forward and reverse drivers 11 and 12 alternately at intervals of one field period on a basis of a scanning signal to scan a picture from the top and the bottom alternately. The control signal from the frequency divider 13 is stored in the memory 10, and picture information in the memory is read out forward/reverse in accordance with a forward/reverse read signal and is outputted to the driver 9. Thus, picture signals are supplied to picture elements from the top or the bottom of the picture in accordance with forward or reverse scanning, and the black-and-white density distribution is reversed at every inversion of the scanning direction and is averaged to eliminate the density difference, and a homogeneous liquid crystal image is obtained.

Title: Circular board positioning device
Inventor: OTA TOSHIYA
IPC: H01L21/68
Filed: 1989-11-17
Abstract: PURPOSE:To dispense with a process that a circular board is very precisely corrected in eccentricity by a method wherein two photodetective elements of a transmission type detection device are formed into a rectangular shape, and the longitudinal direction of the photodetective element is coincident with the direction of the normal of the circular board. CONSTITUTION:A photodetective section 2 is composed of rectangular photodetective elements 4 and 5 disposed in array, where the photodetective elements 4 and 5 are so disposed as to make their long sides parallel with the normal of a circular board 1. Therefore, photodetected signals S and C outputted from the photodetective elements 4 and 5 corresponding to the change of the peripheral edge of the rotating circular board 1 in position are nearly equal to each other in fluctuation, so that signals a and b are equal to each other in fluctuation. In result, as a differential signal c hardly fluctuates and no zero crossing takes place, so that a positioning detection signal h is never transmitted erroneously from a transmission type detection device. By this setup, as the positional fluctuation of the peripheral edge of the circular board 1 caused by the eccentricity between the center of the board 1 and the center of rotation does not affect the differential signal c, the eccentricity of the center of the circular board 1 to the center of rotation can be made large in tolerance.

IPC: H04L27/20
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To increase a transmission amount by validating signal arrangement points not in use in the π/4 shift QPSK modulation system. SOLUTION: A synthesizer 5 synthesizes signals of the π/4 shift QPSK modulation system outputted from two independent equivalent transmission systems synchronized with each other using a same frequency, and transmits the synthesized signal as an output signal. A receiver side demodulates the synthesized signal into a bit string based on phase and amplitude information. The signal arrangement points not in use in the π/4 shift QPSK modulation system are used effectively to double the transmission capacity by synthesizing the signals from the two independent equivalent π/4 shift QPSK modulators 2 synchronized with each other.
