Title: Polymer for water processing
Inventor: KOBAYASHI NORIMASA
IPC: C02F5/10
Filed: 1991-04-19
Abstract: PURPOSE:To simplify the processes of monitoring and analyzing the concn. of chemicals in water and to save manpower by esterifying an alcohol-base microbicide with a part of carboxyl groups of water-soluble polymer containing carboxylic groups and having a function to prevent scaling. CONSTITUTION:The water processing polymer is prepared by modifying a part of carboxyl groups of water-soluble polymer containing carboxyl groups and having a function to prevent scaling with an alcohol-base microbicide having a function to inhibit growing of microbe. This polymer has both of functions to prevent scaling and to inhibit growing of microbe and can be analyzed by a conventional method for analysis of a scale-preventing agent. Not both analysis for the scale-preventing agent and the inhibitor of microbe growth is necessary, but both functions to prevent scaling and to inhibit growth of microbes can be monitored only by adopting the analyzing for the scale preventing agent. This saves analysis work.

Title: Toner for high frequency heat fixing in electrophotography
Inventor: NEGORO TOSHIHIKO
IPC: G03G15/20
Filed: 1980-08-21
Abstract: PURPOSE:To obtain a toner for high frequency heat fixing which can be quickly and well fixed by containing a polyethylene glycol having an average mol.wt. in a specific range as a binder. CONSTITUTION:A polyethylene glycol of 2,000-40,000 average mol.wts. is mixed as a binder with coloring agents, and after the mixture is melted by heating, it is ground and classified, whereby the toner is obtained. It is equally well to compound together other materials which evolve heat and melt by absorbing high frequency energy or melt by the effect of heat as a binder. Thereby, quick fixing in a time less than several seconds is made possible, and the sharp fixed images without excessive luster are obtained. In case carbon black is contained, the carbon black per se evolves heat by high frequencies and therefore if it is contained at <=10wt%, it is usable without danger of ignition.

Filed: 1988-05-13
Abstract: PURPOSE:To improve the picture quality of a still picture without adding an exclusive-use frame memory by diverting a frame memory for detecting the movement of a picture, which becomes unnecessary during a still display operation, to a frame memory to store the unprocessed signals of a still display picture. CONSTITUTION:When a command signal for the still display operation is given to an input terminal 12, the operation of a movement detecting circuit 5a is stopped, and a switch S1 to compose a switch 8c is switched to a lower side. Accompanying this, a movement detecting part 5 starts taking preprocessed video signals in a frame memory 5b. When the taking in of the signals is completed, preprocessed video signals for one frame taken in the memory 5b are repeatedly read in a frame cycle and supplied to a low frequency replacing device 8a. On the other hand, a loop is formed between the input and the output of a frame memory 4b of an inter-frame interpolating part 4, and the video signals for the frame taken in immediately after the command for the still display operation is generated are repeatedly read. As the result, the still picture, in which vertical resolution is improved by the replacement of the low frequency, is displayed.
