Title: Semiconductor device
Inventor: IZAWA RYUICHI
IPC: H01L29/78
Filed: 1989-11-01
Abstract: PURPOSE:To suppress the expansion of an electric field from a drain to the bottom of a channel region by thinning a base SiO2 film (insulating film) under drain and source diffusion layer, and opposing the drain diffusion layer to a base electrode through this film. CONSTITUTION:In a thin film substrate SOI transistor consisting of an Si substrate 2, formed on a SiO2 base 1, a drain diffusion layer 3, a source diffusion layer 30, a gate insulating film 4, and a gate electrode 5, a base electrode 6 is provided opposite only at the bottom of the drain diffusion layer 3. Since the electric field, which expands from the drain 3 to the base SiO2 base 1, is distributed principally between it and the base electrode 6, the expansion to the source side is suppressed. As a result, by enlarging the subthreshold coefficient, short channel can be realized.

In the case when a movable part approaches an end of displacement, the FET 24-1 is put off, an electric current of the electromagnetic coil 9a is accumulated in a capacitor 28-1 as electric charge, and an electric current value is suddenly reduced from the catching electric current to a holding electric current. Energy accumulated in the capacitor 28-1 is used at the time of starting magnetization of a following electromagnetic coil 8a.  On the contrary, energy of a capacitor 28-2 is used on the electromagnetic coil 9a.

IPC: G06T1/00
Filed: 1987-11-10
Abstract: PURPOSE:To increase a transfer speed and to reduce recording capacity by recording only the necessary min amount of matrix data, by selecting only the data during an unblank signal generating period among the data read from an image digital memory. CONSTITUTION:An Lo decremental counter 16d starts decremental counting from Lo(dot) in the timing of the start row of one line. When the output Lx of a PROM(3)16b is coincides with the output of the Lo decremental counter 16d, the reversal output Q of a flip-flop 16e becomes active. At this time, a 2Lx decremental counter 16f starts the decremental counting of 2L(dot) and, when 2Lx(dot counting) is finished, the output of the 2Lx decremental counter 16f is inputted to the flop-flop 16e and the reversal output Q becomes inactive. By this method, an unblank signal is formed at every one line and data is sent to an image recording apparatus 18 to be recorded. In the image recording apparatus 18, the recording/regeneration of data is performed only during a period when the unblank signal is active.
