Abstract: PURPOSE: To form a polycrystalline silicon film of uniform crystal particle size in a short time. CONSTITUTION: A rough surface 1a with a roughness of 10Å or above on a flat transparent insulating substrate 1 (quartz glass, highly heat-resistant glass). An amorphous silicon film 2 is formed on the insulating substrate 1 with the rough surface 1a by low pressure CVD or plasma CVD.

Abstract: PURPOSE:To obtain a reproduced color picture in good color tones, by controlling easily and accurately the color balance of a color picture which is reproduced by a matrix array of picture elements obtained from the picture data out of a solid-state image pickup element, by making spaces between picture elements of the matrix array different for each color. CONSTITUTION:The picture data transferred synchronously with the clock pulse given from an oscillator 8 is led to an A/D converter 10 through a gate 13 and then converted into a digital picture data. At the same time, the oscillation output of the oscillator 8 is supplied to a presettable counter 16. The counted value of the counter 16 is reset every time the picture data transfer clocks are counted and the count value reaches the preset value. The preset value of the counter 16 is set at a proper value for each primary color in order to obtain a color balance which is decided by the exposure time of each primary color decided by a color separating filter 5. Then the scanning lines, i.e., the lines equal to the number of clock pulses divided with the preset value which is preset to the exposure of each primary color are thinned. Then the digital picture data is extracted.

This waterproofing agent solution is sprayed from a spray nozzle on the surface of the lightweight aggregate and thereafter, the resulting aggregate is cooled to ordinary temp. of about 30 deg.C and the solvent is removed from it to obtain the objective lightweight aggregate which is coated with the waterproofing agent in a coating weight equivalent to about 5 to 8wt.% of the weight of the aggregate and shows about <=5wt.% water absorption after immersing it in water at 25 deg.C for 30min. Then, about 600 to 800kg of aggregate contg. about >=50wt.% of the lightweight aggregate treated with the waterproofing agent is blended with about 380kg of cement and an adequate amount of water is added to the blend and the resulting blend is kneaded. Thereafter, the kneaded material is molded and hardened to obtain the objective concrete of which initial strength is not reduced even after a lapse of long time.
