Abstract: PURPOSE:To obtain the title excellent fabric of little smoking, resistant to melt snagging by coating a fabric with a dope prepared by dissolving in a solvent a chlorinated vinyl chloride resin and specific metal-contg. inorganic solid powder followed by solvent removal and gelling the resin component. CONSTITUTION:A dope is prepared by dissolving or dispersing in an organic solvent (e.g., tetrahydrofuran) (A) 100 pts.wt. of a chlorinated vinyl chloride resin, pref. 60-72% in chlorine content and >=0.37 in specific viscosity, (B) a softening agent (e.g., selected from halogen-contg. plasticizers, phosphorus-contg. plasticizers etc.), and (C) >=10 pts.wt. of metal-contg. inorganic solid powder selected from compounds of group II-V metals. This dope is coated on the both surfaces of a base fabric followed by heating and vaporizing said solvent to effect gelling the resin component, thus obtaining the objective flame- retardant fabric. This fabric gives such characteristics as little smoke generation even exposed to sparks or flames, resistance to causing melt snaggings, and prevention of flame spreading.

Title: Developing device for magnetic toner
Inventor: KAWANA KENICHI
IPC: G03G15/09
Filed: 1981-08-13
Abstract: PURPOSE:To prevent a blocking phenomenon of toner, by attaching a slender permanent magnet at the outside of a hopper-shaped magnetic toner tank having a guide plate so as to have an interference with the rotary magnetic field of a permanent roll at the lower opening part of the toner tank. CONSTITUTION:A hopper-shaped toner tank 4 having a guide plate 5 is set opposite to a developing sleeve 2 containing a permanent roll 3 which turns internally. The magnetic toner supplied to the sleeve 2 is controlled by a doctor plate 6. A permanent magnet 10 having a length almost corresponding to the length of the magnetic pole of the roll 3 is attached at the outside of the toner bottle 4b of the tank 4. With rotations of the roll 3, the rotary magnetic field and the magnetic field of the magnet 10 have the interference to each other.

Title: Encapsulated ink composition and pressure-sensitive recording medium
Inventor: TOTANI KAZUO
IPC: C09D11/106
Filed: 1993-05-28
Abstract: PURPOSE:To obtain a microencapsulated ink which gives a pressure-sensitive recording medium excellent in color forming properties and free from short staining, by mixing a microencapsulated chromogenic substance with a compound curable by actinic radiation and having a specified viscosity and hardness. CONSTITUTION:This ink composition contains a microencapsulated chromogenic substance and a compound curable by actinic radiation and having a viscosity of 10-1200cps at 25 deg.C and a pencil hardness (JIS K5400) of at least 2H after curing. The viscosity of the compound has a great influence on the color forming properties of a pressure-sensitive copying paper to be obtained; the use of one having a viscosity above 1200cps gives only a pressure-sensitive copying paper of very poor color forming properties. The use of the compound having the pencil hardness of below 2H gives only a pressure-sensitive copying paper inferior in the prevention of short staining. Among the compounds, those having a viscosity of 10-800cps at 25 deg.C and a pencil hardness of 2H to 8H are particularly desirable.
