Title: Illumination device
Inventor: YAJIMA AKIRA
IPC: G03G15/041
Filed: 1979-11-22
Abstract: PURPOSE:To vary the luminance in the normal direction of the original surface with a simple mechanism for variable magnifications, by moving reflective shades so that the illumination light flux may reach only the slit illumination region on the original surface. CONSTITUTION:Reflective shades 39a and 39b having the first focus near the light source position are rotated with boundary point C as the center and are opened and closed. When shades 39a and 39b are closed, the second focuss agree with each other. For equal size copying, both shades are opened slightly to shift positions of focuses from each other, and original surface 38 is illuminated with slit width l1. Next, for expansion copying, they are rotated to close in the arrow direction, and the illumination width of original surface 38 is narrowed to l2. As a result, the second focuses of them approach each other, and the light intensity is enhanced, and the effective illumination width is narrowed, and thus, the illumination system adapted to expansion copying is obtained. For reduction copying, the light intensity on original surface 38 is weakened and the effective illumination width is expanded by operations opposite to those for expansion copying.

Title: Semiconductor integrated circuit device
Inventor: SUZUKI TOSHIHIDE
IPC: H01L21/76
Filed: 1987-06-17
Abstract: PURPOSE:To remarkably improve the radiation resistant properties without deteriorating insulating ability, by providing a hollow element isolation region surrounded by the wall of an Si oxide film, so that the hollow region virtually acts as an air insulating body. CONSTITUTION:A highly doped P-type polycrystalline Si layer 5 is thermally oxidized, whereby a thin Si oxide film 6 is formed on the surface thereof. Photoresist is applied on the whole surface of the oxide film 6 and a lattice- shaped through hole 8 is opened in the film 6. The substrate is wholly dipped in solution of a solvent, hydrazine so that melt of the polycrystalline Si layer 5 is started. A melting process of the polycrystalline layer 5 progresses under sufficient control until a hollow is defined in place of the layer 5. The element isolation region thus hollowed surrounds the trapezoidal substrate 1, and virtually acts as an air insulating body, whose insulating ability depends little on the Si oxide film on the walls thereof. Accordingly, it is possible to improve radiation resistivity without deteriorating element isolating ability by making the oxide film thin.

Title: Noise eliminating system
Inventor: SUZUKI SHINJI
IPC: H03F3/181
Filed: 1983-08-19
Abstract: PURPOSE:To avoide feeling of disorder based on the listening by using an elecctronic volume controlled by a CPU so as to decrease the sound volume continuously and controlling the electronic volume with a data signal from the CPU so as to restore the sound volume to the originl volume after the changeover of an electronic switch thereby eliminating the notch of the changeover. CONSTITUTION:In changing over the state from the ''tuner on'' into the ''PHONO'', when ''PHONO'' selection information is fed from a key matrix 11 to a CPU12 by an input key, the CPU12 stores a switching signal to a memory 16c and a sound volume at that point of time to a memory 16a respectively. Then every time when a trigger signal from an adder 20 enters, the sound volume value from the memory 16a is incremented by the information extracted from the memory 16a by the command from the CPU12 and its data signal is fed to the electronic volume 21. This operation is continued until the sound volume is minimized. The CPU12 gives a switching signal to the electronic switch 13, which is changed over. Then the CPU12 increments sequentially a data signal conversely up to the sound volume value of the memory 16a so as to operate the electronic volume 21 thereby attaining smooth sound volume increase.

The data file of the fetched image is stored in a storage part 31 together with a frame number, the image fetched for the list image is reduced and it is also stored in the storage part 31. Then, a processing part 33 analyzes the size of the image by the fetched data file and, then, compares the number of lateral picture elements in the image with the number of longitudinal picture elements. Unless the image to be fetched is in the electronic still camera 1, a generated laterally long image list is synthesized (connected) with a longitudinally long image list. The reduced images stored in the storage part 31 are synthesized and the list image is generated so that the images are displayed in one lot.
