IPC: B41M5/20
Filed: 1986-09-24
Abstract: PURPOSE:To obtain a multicolored image by a single process, by heating a conductive base coated with a material comprising a uniform mixture of three kinds of microcapsules enclosing leuco dyes capable of forming respectively cyan, magenta and yellow colors, color developers, decolorizing agents and heat-fusible substances as core substances, by passing an electric current to the base. CONSTITUTION:When three different voltages are applied, microcapsules respectively for cyan, magenta and yellow colors form the colors respectively at temperatures T1, T2, T3 (T1<T2<T3). When decolorizing agents 8, 11 are so selected as melted only at temperatures not lower than T2 and T3, respectively, for example, at the temperature T2 the leuco dye for magenta and a color developer for the dye react with each other to form the color, whereas the microcapsules for cyan undergo melting of the decoloring agent, whereby the color-developed cyan dye is decolorized. Thus, the microcapsules for cyan, magenta and yellow independently form the colors at different temperatures, and a multicolor image can be recorded by a single process.

Abstract: PURPOSE:To obtain a long, one-dimensional sensor, which is compact and highly reliable and can perform high speed operation, by selectively diffusing impurities so as to form an amorphous silicon semiconductor film and a thin film, whose optical forbidden band width is smaller than the amorphous silicon, and applying wiring in three dimensions. CONSTITUTION:At the initial period of operation of a long, one-dimentional sensor, first electrodes 12, 12', and 12'' and second electrodes 17'' are opened. Then, the first electrode 12' is grounded, and the second electrodes 17'' are sequentially grounded from the end, or in accordance with a random number. From individual light receiving elements, to which light is projected, optical currents, which are generated by a-Si:Hpin diodes constituted in a thin film 15, are taken out. Then, the first electrode 12'' is grounded, the second electrodes 17'' are sequentially grounded, and the optical currents are taken out. When all the first electrodes are grounded by one round and the optical currents are all taken out, the initial state is restored. Then this procedure is repeated.

Title: Semiconductor device
Inventor: YAMAGATA NARIHITO
IPC: H01L21/027
Filed: 1984-10-27
Abstract: PURPOSE:To avoid restrictions to the arrangement of elements and wirings in the element-forming region, by a method wherein marks for precise positioning of semiconductor chips are formed at the part other than the chip element-forming region. CONSTITUTION:A positioning mark 2a is composed of e.g. a poly Si layer 9 of the lower layer and an aluminum film 10 of the upper layer. The element- forming region 1 is formed out of e.g. a semiconductor substrate 4, a diffused layer 5, an oxide film 6, a smooth coat 7, and a passivation film 8. The position of a semiconductor chip is precisely determined by irradiating the positioning mark 2a under scanning with e.g. faint laser rays, and then by detecting its reflected light. Besides, restrictions to the arrangement of elements and wirings in the region 1 can be avoided because of the formation of marks 2a outside the region 1. The shape of the positioning mark, the number of marks provided in a chip, and its structure may be arbitrary one.
