Title: Electrode for electrostatic recording
Inventor: TOMITA SATORU
IPC: G03G15/00
Filed: 1979-02-09
Abstract: PURPOSE:To obtain correct circular latent image dots on a recording medium by providing a conical electroconductor to the end face of each recording needle of an electrostatic recording electrode so that stable discharge will be available at all times from a specific part of the end face of each recording needle. CONSTITUTION:In a recording electrode 1d, the insulator portions around the recording needles 1b are removed by liquid honing or other means to form the spaces 1e, then the conductors 1f are formed substantially conically at the end faces of the recording needles 1b by plating or other means and then the entire end faces of said conical conductors 1f are coated with an insulating material such as resin 1g to form a flat end. Thus, since the end of each recording needle forms a conical protuberance, the discharge starting point is specified to a part near the top of the conical protuberance. This allows the formation of the latent image dots having a relatively correct circular shape on the recording medium.

Title: Fluorine containing cation exchange resin membrane for electrolytic use
Inventor: UKIHASHI HIROSHI
IPC: C08J5/22
Filed: 1978-02-10
Abstract: PURPOSE: Electrochemically and mechanically stable, fluorine-containing cation- exchanging resin polymer, free of bubble formation on electrolytic membrane surface is formed by mixing a specific amount of fibrillar C 2 F 4  polymer and incorporating functional groups consisting of COOH or group convertible to COOH.  
     CONSTITUTION: C 2 F 4  polymer having first particle diameters less than 5 microns is mixed with a fluorine-containing polymer having carboxylic group or a group convertible to carboxylic group. The mixture is subjected to shear force when mixing or after mixing to form the C 2 F 4  polymer into fibril state. The addition of C 2 F 4  polymer in the range of 0.5 to 4.0 percent by weight effectively prevents the formation of small or large bubbles on electrolytic membrane surface, and enhances mechanical property of the ion-exchange membrane without reducing electrolytical property.
