Abstract: A fine-particle classification apparatus includes an aerosol generation section which generates an aerosol containing fine particles in a medium background gas, a fine-particle classification section which classifies the fine particles contained in the aerosol in a sheath gas, and an introduction section, between the aerosol generation section and the fine-particle classification section, which introduces the aerosol generated in the aerosol generation section into the fine-particle classification section. The introduction section uses a carrier gas with an adequately high velocity to introduce the aerosol generated in the aerosol generation section to the classification section using a pressure difference.

Abstract: A thin film is formed on a substrate in a reaction chamber using a photo CVD technique by decomposing a reactive gas supplied to the reaction chamber by means of light irradiated through a light introducing window. The reduction in film deposition rate due to clouding of the light introducing window is corrected in order to form a thin film of a desired film thickness.

Abstract: An artificial neural function circuit includes an organic thin film element having a resistance state which changes in dependence on an electrical signal inputted thereto and exhibits information processing function similar to that of a nervous system. The organic thin film element has such physical properties that the changed resistance state is held as it is at least for a predetermined time period even after removal of the electric input signal and that the direction in which the resistance is increased or decreased depends on the polarity of the electric input signal. As an example of such organic thin film, a lead phthalocyanine thin film is employed.

Abstract: A color image duplicating device comprises a function generator (60) for generating a plurality of functions of n degree wherein elements of color separated data (201, 202, 203) from a color original (1) are variable, a storing device (66) for storing predetermined coefficients, and an arithmetic unit (61, 62, 63) for performing the calculation to find the product and sum of outputs from the function generator (60) and that of the storing device (66). An output from the arithmetic unit (61, 62, 63) is applied to a color recorder (3) to form a color duplicated image.

Abstract: To overcome the tendency of the recording head of a dot printer to become inoperative in a range below a threshold level, a gray scale input signal is modulated with an oscillating signal so that the modulated signal oscillates above and below the threshold level to reproduce halftone values below the otherwise inoperative range.
