Title: Ink backflow stopper composition
Inventor: MIYASHITA HIROSHI
IPC: B43K7/02
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide an ink backflow stopper composition which moves while scrapping off ink sticking to the internal wall of an ink storage part by adding at least an α-olefin oligomer and/or an ethylene-α-olefin copolymer, a fine powder silica and a fluorine-modified silicone oil. SOLUTION: A fluorine-modified silicone oil used in the ink backflow stopper composition has a side chain trifluorocarbon which repels ink sticking to the internal wall of an ink storage pipe off the internal wall face, so that the ink is scraped off by this composition. In addition, the composition hardly sticks to the internal wall of the ink storage part on account of the side chain trifluorocarbon of the fluorine-modified silicone oil used in the composition. Besides, since the loss of weight of the composition is little, it shows an ink scraping effect maintained until the complete consumption of the ink.

Abstract: PURPOSE:To make it possible to detect an internal failure surely without being affected by a core magnetic saturation, by detecting the internal failure of a series transformer through the current flowing through at least a pair of reflux windings connected in inverse parallel and built in the series transformer. CONSTITUTION:A pair of reflux windings 33a and 34a built in a series transformer 3 are respectively wound and placed to a core with the same winding and are connected in inverse parallel.
