Abstract: PURPOSE:To increase a contrast ratio and to decrease flickers without increasing the number of stages and lowering an opening rate by setting the parasitic capacitance between the gate of one TFT and a display picture element electrode larger and utilizing the same as a storage capacitance. CONSTITUTION:Plural pieces of the thin-film transistors (TFTs) 20a, 20b respectively connected to two pieces of scanning lines 21a, 21b selected in different periods are connected to the display picture element electrode 25 of one picture element. The capacitance Cgs 1 between the gate of the TFT 20b and the display picture element electrode 25 is formed larger than the capacitance Cgs 2 between the gate of the TFT 20b and the display picture element electrode 25 by designing the patterns that the gate-source overlap area of the TFT 20b is larger than the gate-source overlap area of the TFT 20a. The generation of the flicker is prevented in this way without increasing the number of steps and lowering the opening rate.

Filed: 1979-08-20
Abstract: PURPOSE:To protect the coil from damage and enhance productivity, by applying high-frequency vibration to a core, which is to be inserted into the core slot set in a jig, to reduce insertion pressure. CONSTITUTION:The output of a high-frequency power source 22 is adjusted to about 3KW and its frequency is adjusted to about 15KHz.

Abstract: PURPOSE:To decrease the amount of transfer data of a binary image by compressing distance data and reducing odd and even data. CONSTITUTION:When the distance of a first one signal of 1 from the start end of a line of the binary image is 101 and there is a next one signal 1 on the line, the most significant digit bit(MSB) is set to 0 to generate data (b) having compressed distance data by deleting the least significant digit bit(LSB) of binary-coded data on the distance as low-order bits; and similar data are generated in order (c). The parity states of respective distance data are represented in order with signals of 0 and 1 and when a signal of 0 (even) continues to the end, odd and even data (a) which do not have the representation are generated. When there is not the next signal of 1 up to the end of the line, on the other hand, the MSB is set to 1 (d) and the next line is processed.
