Title: Image scanner device
Inventor: TANIMURA MASAHITO
IPC: G06T1/00
Filed: 1985-07-25
Abstract: PURPOSE:To make an image scanner not expressing an intermediate density and handling presence/absence of white/black levels only express a pseudo multi-value with an inexpensive means by controlling variably a threshold voltage compared with an analog signal output from an optical read means as time elapses. CONSTITUTION:The threshold voltage is the sum of an output of a white noise generator 7 divided by a variable resistor 8 and a voltage decided by a variable resistor 6 and the sum changes irregularly with respect to time, and since the probability of the output of a comparator 5 being logical '1' is increased as the output of a CCD image sensor 3 increases, the frequency of the output being logical '1' is increased depending on the density of the input graph to express the intermediate tone in pseudo way. In this case, the variable resistor 6 adjusts the density and the variable resistor adjusts the contrast.

Title: Memory pattern layout of semiconductor memory device
Inventor: MATSUO RYUICHI
IPC: G11C11/401
Filed: 1990-06-22
Abstract: PURPOSE:To reduce fail rate during a manufacturing process by arranging a dummy memory so as to surround the main memory area of a semiconductor memory device. CONSTITUTION:A dummy memory 7 is disposed so as to completely surround a main memory area 5. The dummy memory 7 is arranged so as to surround the main memory area 5 constituted of word lines W1-Wn and bit lines b1-bn in a matrix shape. The word lines W1-Wn and the bit lines b1-bn are shared mutually. Word lines Wd1, Wd2 and bit lines bd1, bd2 are used as ones exclusive for the dummy memory. Even when a selective High signal is applied to the word lines W1-Wn, the dummy memory is turned 'OFF' positively. Even when the selective High signal is applied to the bit lines b1-bn, the dummy memory is turned 'OFF' positively, thus operating only the main memory area. Accordingly, since the dummy memory is disposed at the terminal section of a main memory array section, a crack does not reach the main memory array section even when the crack is generated in the insulating film, etc., of the terminal section of the memory area, thus stably operating a semiconductor memory device normally.
