Title: Molecular beam crystal growth device
Inventor: KONDO KAZUHIRO
IPC: H01L21/203
Filed: 1985-02-19
Abstract: PURPOSE:To make it feasible to detect the amplitude proportional to the reflection intensity eliminating any preliminary trial by means of intermittently opening and closing a shutter in front of a monitor substrate at specified cycle for a few seconds. CONSTITUTION:Electron beam signals may be detected in the period with relatively larger amplitude under the initial opening state by means of opening and closing a shutter 22 on the gallium side however the detection becomes harder corresponding to the diminishing amplitude proportional to the increasing thickness of gallium arsenic layer. At this time, a growing film on a monitor substrate may be stabilized since arsenic only may be grown by means of closing the shutter 22 on the gallium side for only a few seconds to make it feasible to observe the signals in the period with sufficiently large amplitude when the shutter is opened again. Resultantly the growing state in a molecular beam crystal growing device may be observed by means of constantly utilizing the monitor substrate.

Title: Liquid crystal display device
Inventor: MIYOSHI KATSUYA
IPC: G02F1/133
Filed: 1994-03-02
Abstract: PURPOSE:To suppress fluctuation in display of periodicity and to improve the outlook by determining on-off in frames by the output from a random number generator and intensity level value and driving a liquid crystal display device at the time of intensity level displaying with plural frames. CONSTITUTION:A frame synchronizing signal 1 is inputted to the random number generator 2 and eventually, the random numbers are inputted to a comparator 3. On the other hand, the intensity data of respective pixels is inputted to the comparator 3 in synchronization with the frame synchronizing signal 1. The supply voltage to the pixels is switched by lighting and non-lighting and the frames to be thinned are determined by the random number and the intensity level values in this comparator 3. This random number generator 3 may generate the random numbers by using a register which successively generates the random numbers skeptically but simpler circuits suffice if a table of random numbers is previously written in ROM and the random numbers are successively read out of this table. In such a case, the lighting state is controlled by the random numbers and, therefor, the continuation of the same lighting and non-lighting states at the time of the medium intensity level is obviated.
