Filed: 1984-11-20
Abstract: PURPOSE:To increase the number of gradations without decreasing the resolution by using a gradation pattern where the arrangement of black picture elements is different in addition to the gradation pattern of an organized dither. CONSTITUTION:The content shown in a figure 2 is stored in an ROM 1 in case of correspondence to, e.g., 3X3 dither matrix, and dither picture data Bxy is read corresponding to intermediate picture data M (0-13). Counters 2, 3 are respectively ternary picture element and line counters, by which (x, y) direction of address signal is generated. A mean additive density where the number of black piecture elements represents gradation is utilized by the organized dither method, and 0-13 gradation patterns are obtained even by a 3X3 dither matrix by utilizing that the density is observed differently depending on the difference in the arranging position even when the number of black picture elements is the same and the number of gradation is increased by 4 gradations than conventional systems.

Title: Semiconductor resistance element and semiconductor device
Inventor: SHIMIZU NOBUO
IPC: H05B41/02
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To reduce the lateral current leak for improving the breakdown voltage by providing a transistor structure around a first P-type diffusion layer with a voltage applied to electrodes to provide the turn-off state. SOLUTION: When a voltage is applied between electrode terminals 31 and 3, a semiconductor element provides a resistance value due to the natural resistance of a P-type diffusion layer 30 used as a resistor where the P-type diffusion layers 30 and 35 are used as drains and sources to form transistors (second transistor structure and third high-breakdown voltage transistor structure) with gates 37. The source, i.e., the diffusion layer 35 and gate 37 are connected to a terminal Vcc to thereby forcedly turn off the transistor. Thus it is possible to suppress the lateral leak current to flow from the diffusion layer 30 to be used as a resistor to the diffusion layer 35 and raise the breakdown voltage.
