Title: Color image recording device
Inventor: DAITO CHIAKI
IPC: G03G15/01
Filed: 1986-08-21
Abstract: PURPOSE:To perform accurate color matching even if an error in conveyance is caused by positioning an image in both lateral and longitudinal directions of electrostatic recording paper by detecting registration marks formed on the electrostatic recording paper and the edges of the electrostatic recording paper. CONSTITUTION:An edge detector 8 detects the edges of the electrostatic recording paper 4 at constant intervals of time and decides the expansion and contraction or snaking of the electrostatic recording paper 4. Consequently, if the expansion and contraction or snaking occurs, a correction is made only by the minimum controlled variable of a positioning means at each time, so even if the edge of the electrostatic recording paper is flawed or made dirty, partially, the image is not corrected greatly and the color shift is minimized. Further, when a mark detector 10 measures intervals of registration marks 9 and computes recording timing periods, the difference between the number of lines recorded until the detection of the registration mark 9 and the number of lines set at the time of a 1st recording of registration marks 9 is calculated. Then, the recording timing period is so determined that lines which are the difference more are recorded between registration marks 9. Consequently, errors generated owing to an error in conveyance are never accumulated.

Title: Solar heat selective absorption plate and its manufacturing method
Inventor: DOI SHOJI
IPC: F24J2/48
Filed: 1988-08-05
Abstract: PURPOSE:To improve the solar ray absorption ratio of a material having a high corrosion resistance without an increase in solar ray emissivity by preparing Fe-Cr-Al stainless steel plate, containing a specific amount of Cr and Al, to a particular surface roughness, and producing alumina whiskers having a length not less than 0.1mum and less than 1.0mum on the surface of the plate. CONSTITUTION:Fe-Cr-Al stainless steel plate containing 12-28wt% of Cr and 1-6wt% of Al is required to increase its surface roughness in order to increase an area for far-infrared ray radiation. To obtain such a surface roughness of not less than 0.2-1.0mum in Ra, sand-blasting is carried out on the surface of the plate. Next, a high temperature oxidization process takes place by holding the plate in an oxidizing circumstance at a temperature of 850-1,000 deg.C for 1-4 hours to produce alumina whiskers having a length not less than 0.1mum and less than 1.0mum. When the distances b between the tips of the alumina whiskers are prepared nearly equal to the major wave length of solar rays of 0.3-1.0mum, the number of times of solar ray reflection on the surface increases so that the absorption ratio improved.
