Filed: 1981-06-19
Abstract: PURPOSE:To obtain a copy which exists as a copy during the necessary time and disappears after a certain time elapses, by contg. a diazo compound, a mercaptan compound and a photocromic material on a supporting material. CONSTITUTION:A diazo compound, a mercaptan compound and a photocromic material are contained on a supporting material and a diazo copying material is obtained. In order to obtain a copy image by usig this diazo copying material, the material is developed under the alkali atmosphere after exposure, then a copy in which a clear image that has no change of properties by a light in a fixed time and has a large contrast is maintained and thereafter the dye of both imaging part and nonimaging part disappears completely, is obtained. The coexistence with the mercaptan compound in the above-mentioned copying material brings a remarkable decrease of photosensitivity by alkali treatment and also the effect to control autocoupling reaction under the irradiation of UV of the diazo compound.

IPC: H02N11/00
Filed: 1985-05-01
Abstract: PURPOSE:To continuously convert thermal energy into electric energy by heating sealed gas in a rotary vessel by hot air, and rotating it to intermittently apply a high voltage between electrodes. CONSTITUTION:A duct 7, a drive motor 14, a magnetic conductive material 12, and a rotational shaft 25 are mounted on a trestle, and a rotary vessel 29 mounted on the shaft 25 is rotated by the motor 14.
