Title: Variable multiplication method for copier of scanning exposure type
Inventor: OGAWA MASAYA
IPC: G03G15/041
Filed: 1977-10-11
Abstract: PURPOSE:To make it possible to simply and precisely change the multiplication by merely shifting an optical unit only in changing the multiplication while an original drawing plane together with the plane to be projected on a photoreceptor are being firmly fixed. CONSTITUTION:Generally, in case the original image is projected, let the length of optical path between original image and lens be am, the length of optical path between lens and image face be bm, and projection multiplication be m, in order to change the projection multiplication, the three factors, optical path length am, optical path length bm, and conjugate distance must be varied. Now, at the multiplication m1, let the points be A1, B1, L1, M1, N1, and let the points at the multi- plication m2 be A2, B2, L2, M2, N2, then formulas 2 and 3 can be derived. Therefore the projection multiplication can be varied by shifting the optical units such that the formulas 2 and 3 may be satisfied. In case the optical unit 6 stands still, and scans and projects while the document and the photoreceptor are being relatively shifted, for example, in order to reduce the original image to 0.8 times, the shifting speed of the original be increased to 1/0.8=1.25 times as quick as the equal multiplication.

Title: Picture composing device
Inventor: IKEDO TSUNEO
IPC: G06T13/60
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain the expressive and real video of a gaseous material by leaving an overlapped numerical value as it is when the value Z (a view point coordinate value) of the gaseous object is closer to a view point than a face defining object and setting the numerical value to be a specific value when the value Z is distant. SOLUTION: A minimum graphic element expressing the gaseous object is read from a picture memory 5. Luminance fl is inputted to a smoothing filter circuit 7. The value Z fz and the value Z fz of the face defining object are compared by a comparing circuit 8. A selector 9 selects the overlapped number (m) as it is when the gaseous object is at the front face of the face defining object and selects zero or a prescribed value (n) when it is at the rear based on the comparing result. The overlapped number smoothed by a smoothing filter 10 is transformed to a prescribed radioscopy coefficient through a storage element 11 and respectively multiplied by the luminance gl of the gaseous object after smoothing, by the luminance sl of the face defining object in multipliers 12a and 12b. After then, these are added by an adder 13 to obtain a composite image.

Title: Vertical type layer light emitting body, its manufacture and light emitting display device
Inventor: HAYASHI SHIGEO
IPC: H05B33/26
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To increase effective numerical aperture of a display element of a fine two-dimensional matrix type, by restraining diffusion of carriers generated when crystal is excited. SOLUTION: PbI2 as a vertical type layer crystal is formed on a slant GaAs substrate 11 as a substrate. The axial direction 13 of the layer is inclined at 45 deg. to the normal direction 14 of the substrate. When a fine region in the element is excited, a light emission near field pattern becomes a narrow fine ellipse in the axial direction of the layer, because carriers scarcely diffuse in the axial direction of the layer. As a result, a two-dimensional display element of fine picture element size can be realized by performing one-dimensional element isolation.
