IPC: G09G3/36
Filed: 1990-11-15
Abstract: PURPOSE:To improve reliability and the resolving power in a sub-scanning direction by impressing voltage pulses of both polarities of the absolute value above the saturation value or below the threshold of an element in a selection period and impressing the voltage pulse group of the absolute value below the threshold of the element in a non-selection period.

Title: Controller for washing machine
Inventor: KIUCHI MITSUSACHI
IPC: D06F41/00
Filed: 1989-11-29
Abstract: PURPOSE:To allow setting or revising the residual time indications each time by a method wherein fouling or rinsing status is detected by a transmission degree detector in an early stage of washing, rinsing or dewatering operation, and an optimum control time is assumed and set. CONSTITUTION:Water is supplied up to an extreme low water level and agitation is controlled by a cloth amount detecting subroutine to judge the cloth amount, and a water level is set corresponding to the cloth amount. At this time, the standard time corresponding to the cloth amount is indicated as the residual time. The water level is detected during water supply step, and when it reaches the set level, washing agitation step takes place. Optical sensor signals are input, and the change ratio of the optical sensor signals is detected to judge whether or not it reaches saturation. When it reaches saturation, fouling is judged corresponding to the saturation time and the transmission degree, and an additional washing time is set, and the residual time indication is revised. Then, it is judged whether or not washing is finished, and when washing is completed, drain and intermediate dewatering are carried out, and water supply for rinsing process follows. Dewatered conditions are judged depending upon changes in the output signals of the optical sensor during intermediate or final dewatering step, and dewatering time is changed and the residual time is revised.

Title: Single chip type cache memory
Inventor: KIKUCHI TAKASHI
IPC: G06F12/08
Filed: 1989-12-01
Abstract: PURPOSE:To improve the hit rate of a cache memory by comparing an address supplied from the external with the address in a write buffer and outputting data in a corresponding register onto a bus at the time of coincidence between them. CONSTITUTION:A cache memory C-MEM having a write store buffer WSB compares the address inputted from an MPU with the tag address stored in a directory memory DIM. Since the address in a store register of the write store buffer WSB is compared simultaneously with this comparison, the MPU can read/write data in the shortest machine cycle without accessing a main memory at the time of coincidence (hit) between both addresses though the comparison with the directory memory DIM results in disaccord (mishit).
