Title: Manufacture of cleaning material
Inventor: TAMADA KEIKICHI
IPC: A47L13/16
Filed: 1988-11-24
Abstract: PURPOSE:To obtain cleaning material excellent in cleaning capacity by folding an elongated fiber material in zigzag while closely contacting each other in such a manner as to have the substantially equal width to be formed like a belt and sewing at the central portion thereof. CONSTITUTION:Long filaments made of plastics such as nylon, polypropylene are packed into a small bundle, and the bundle is folded in zigzag while closely contacting each other in such a manner as to have the substantially equal width to be formed like a belt. The center of the belt-like body is sewed by a sewing machine. Sewing is performed in one or several lines. When sewing is thus performed, the bundle of filaments is folded in zigzag and formed like a belt so as to form a belt-like piece 1 which will not get out of shape. The reason for using plastic fiber having high electric resistance like nylon and polypropylene as elongated fiber material, is that at the time of cleaning, static electricity is generated to adsorb contaminants by the electrostatic electricity.

IPC: H01L51/30
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To manufacture an EL panel with high resolution by forming a transparent conductive layer into a pattern, arranging a colored organic electroluminescence medium, and forming a conductive layer on a colored auxiliary picture element into a pattern. SOLUTION: Row electrodes 120 are formed on a transparent substrate 110. A first major EL medium 131 is deposited on a row electrode locating every third by using a proximity separated deposition process in order to form a first major auxiliary picture element. The process is repeated, and a second major EL medium 132 is selectively deposited on a row electrode adjacent to the first auxiliary picture element. The process is repeated again so that a third major EL medium 133 is selectively deposited on the remaining column electrode. A row electrode 140 is formed thereon to obtain an EL panel. The proximity separated deposition technology is especially effective in the manufacture of the EL panel because a molecular material constituting the organic EL medium is naturally sublimated at relatively low temperature of 40 deg.C or lower.
