Abstract: PURPOSE: To reduce energy consumption in exothermic reaction by lowering ignition temperature in a reaction proceeding on a catalyst. CONSTITUTION: A catalyst body comprises a small-diameter channel 2 and a large-diameter channel 4. In a specified mode using a low heat conduction material, the channels 2 and 4 are connected in series and separated from a mixing chamber 6.

Abstract: PURPOSE:To prevent the flocculation of an electric charge generating pigment and to improve the dispersion efficiency thereof by immersing preliminarily said pigment into a solvent. CONSTITUTION:The immersion stage is executed by putting, for example, the charge generating pigment and solvent into a suitable glass bottle, placing the glass bottle on the sand of a ball mill dispersing machine and dispersing the same at a suitable rotating speed, for example, 80rpm. The immersion time is set in a 6-24 hours range. The immersion liquid dispersed uniformly with the pigment by the immersion process is then incorporated into a binder soln. dissolved in the same solvent as the above- mentioned solvent and is thus subjected to the dispersion treatment. The dispersion stage is used for dispersion of an ordinary photosensitive liquid. Said dispersion is executed by setting adequately the rotating speed and dispersion time in, for example, a homo mixer or ultrasonic dispersion machine. The resultant photosensitive liquid is coated on an aluminum cylindrical drum by various coating methods such as immersion method and blade coating methods.
