Filed: 1990-07-12
Abstract: PURPOSE:To increase the density of semiconductor layers making use of the thin film technology by a method wherein the thin film semiconductor layers having adjacent P type semiconductor regions and N type semiconductor regions through the intermediary of channel regions are formed in a pair of two layers while respective P type and N type semiconductor regions are arranged in the positions to be opposed to one another and an insulating layer is interposed between both semiconductor layers. CONSTITUTION:Thin film semiconductor layers having adjacent P type semiconductor regions 2A, 2B and N type semiconductor regions 3A, 3B through the intermediary of channel regions 6A, 6B are formed in a pair of layers while both semiconductor layers are arranged in the positions wherein respective P type semiconductor regions 2A, 2B and the N type semiconductor regions 3A, 3B are opposed to one another with an insulating layer 4 interposed between both semiconductor layers. When respective P type semiconductor regions of respective semiconductor layers are charged with positive potential while respective N type semiconductor regions are charged with negative potential, the charges in mutually inverse polarity are generated in the opposite surface side of the channel region of respective semiconductors. Resultantly, the signal logic to be memorized can be written-in and read-out by controlling the potentials in the channel regions thereby enabling said logic to be used as a memory cell of a SRAM.

Title: Image inverting method
Inventor: SUZUKI KENJI
IPC: H04N1/40
Filed: 1986-08-06
Abstract: PURPOSE:To optimize the brightness of an image which has been inverted, and also, to vary no brightness even if gamma is converted, by varying no standard gray level at the time of the inversion. CONSTITUTION:At the time of inverting an image which has been brought to an image pickup by a camera 30, from a negative image to a positive image, or from a positive image to a negative image, it is executed so that a standard gray level is not varied at the time of the inversion. Also, in order to maintain the brightness of the whole screen so as to be constant in case the negative image and the positive image have been inverted, it is desirable especially that the standard gray level in which the brightness is not varied at the time of inversion of the negative image and the positive image is set to about 23% of a white level. In this way, the standard gray level, namely, brightness of a point of a neutral density is not varied, therefore, brightness of the whole screen becomes optimum.

Title: Image forming device
Inventor: TAKAYANAGI YOSHIAKI
IPC: G03B27/52
Filed: 1980-12-27
Abstract: PURPOSE:To achieve accurate positioning and timing control by providing a switch which detects an optical system approaching its home position and another switch which detects the optical system being at the home position. CONSTITUTION:An optical system, once finishing the exposure of an original by moving forth, is inverted and starts moving back. When a light-shielding plate 1-A passes by an optical switch PS1 and the approach of the optical system to its home position is confirmed, an optical-system driving system is turned off and the optical system returns to the home position by inertia. If a light-shielding plate 1-C does not shield an optical switch PS2 when the optical system starts moving forth, the optical system is not at the correct home position, so the optical system is moved back until the optical switch PS1 is put in operation by the light-shielding plate 1-A.
