IPC: G03G15/00
Filed: 1992-09-08
Abstract: PURPOSE:To prevent an occurrence of a shade caused by a high or low printing dot density to realize a constant-density printing in a page printer. CONSTITUTION:In a controller part 1, data of printing information is processed. In an engine part 2, an electrostatic latent image is formed on a printing drum 12, a toner is supplied onto the printing drum 12 by rotating a developing roller 16 to develop the electrostatic latent image, and the developed image is transferred to paper. In a printing control method for a page printer in which the paper is fed in synchronism with the forming of the electrostatic latent image for conducting printing, one page of paper is virtually divided into a plurality of layers in the controller part 1, and a printing dot density is calculated per layer and transmitted to the engine part 2. In the engine part 2, printing is carried out while the speed of the developing roller is controlled in accordance with a printing density by referring to the printing dot density per layer transmitted from the controller part.

Abstract: PURPOSE:To obtain the subject substance in high yield at a low cost by carrying out Hofmann degradation reaction of a paramethylbenzyltrimethylammonium halide derivative in the presence of a polyvinylpyrrolidone catalyst in an aqueous solution containing an alkali metal hydroxide. CONSTITUTION:In synthesizing a compound of formula II by Hofmann degradation reaction of a compound of formula I (X is H, halogen or lower alkyl; (n) is 1-4; Y is halogen) in an aqueous solution containing an alkali metal hydroxide (e.g. 30-40wt.% NaOH aqueous solution), a polyvinylpyrrolidone is used as a catalyst to produce the objective compound in high yield. Especially in case of using an insoluble polyvinylpyrrolidone, separation of the objective compound and recovery of the catalyst can be carried out more readily. A solvent such as toluene or chlorobenzene is preferably used for the reaction.
