Title: Photographic printing method and original plate for printing used in execution of this method
Inventor: TSUJI KIKUROU
IPC: G03F1/90
Filed: 1979-12-18
Abstract: PURPOSE: To rationalize the operations of juxtaposing the same images and printing photographs by providing the function of a shading mask and a print-skipping mask by the original plate provided with the image to be printed and the opaque part of the same shape as that of said part of a transparent base.  
     CONSTITUTION: An image 7 to be printed is formed on a transparent base 6, and an opaque part 9 of the same shape as that of the image 7 is provided in the symmetrical position turned 180° around the point 8 outside said image region, whereby an original plate is obtained. When this original is superposedly contacted with a photosensitive material and is exposed, a required image is printed in the region of the image 7 and in the margin part around said region, the print-skipping exposure is carried out. Thence, if the original plate is turned 180° around the point 8, the opaque part 9 is superposed on the already printed image region, and the image 7 to be printed is superposed on the region which had been shaded by the opaque part 9 at the 1st exposure; therefore, if the 2nd exposure is made here, the two images juxtaposed on the right and left are obtainable.

Abstract: PURPOSE:To obtain the stable and even performance of a cathode by impregnating an emitter material forcedly through processes in which a high melting point metallic cap is placed covering a base material which is to constitute the cathode, heated, and quenched to impregnate the emitter material homogeneously. CONSTITUTION:Emitter material 2 is placed in a cap 1 of high melting point metal such as Mo, pressed with a punching machine 6 to form a compressed emitter material 2. The cap 1 charged with the compressed emitter material 2 is put on a porous W base material 3 comprising sintered W so that the compressed material touches to the base material 3. The base material 3 is placed  on a ribbon heater 4 keeping the state, and heated gradually to melt the emitter  material 2. Then it is quenched, the cap 1 is removed from the base material 3,  and a cathode 5 impregnated with the emitter material 2 can be obtained. Thus  an impregnated type cathode of even and stable performance and long life can  be obtained easily.

Abstract: PURPOSE:To provide a small area non-volatile memory by providing n<+>-type layers for surrounding p-type source and drain regions and a floating gate insulated from the n<+>-type layers by using an n-type silicon substrate. CONSTITUTION:n<+>-Type layers 42, p-type source and drain regions 43, 44 are formed in an n-type substrate 41, and a floating gate 46 is formed in an oxide film 46 on the substrate 41.
