Patent number: 9575097Abstract: Composite material sheets containing conductive fibers are laminated, and release films are interposed between the sheets so as to extend from one end to the center of the sheets. The sheets are heated under pressure to shape a composite material. Discrete conductive wires through which a measurement current is passed are connected to end surfaces of the respective layers in the composite material on the side on which the release films are interposed. A common conductive wire through which the measurement current is passed is connected to a surface of one of an uppermost layer and a lowermost layer at an end of the composite material opposite to the side on which the release films are interposed. A current is passed between the common conductive wire and the discrete conductive wires. Currents in the respective layers are sequentially or simultaneously measured using an ammeter.Type: GrantFiled: November 17, 2014Date of Patent: February 21, 2017Assignee: FUJI JUKOGYO KABUSHIKI KAISHAInventors: Ai Kawashima, Hiroyasu Fujita, Naoyuki Sekine

Publication number: 20040092188Abstract: A clothing material structure of fiber cloth containing PAN series activated carbon includes an air-permeable textile as a support layer and fiber cloth containing PAN series activated carbon as an adsorption layer. The support layer and the adsorption layer are bonded together to form the clothing material suitable for the hunter clothing and the protective clothing by way of bonding or needle punching. Accordingly, when the wearer's body heat and body odor try to pass through the clothing made from the material, the body heat may smoothly pass through the adsorption layer while the body odor is blocked and filtered out by the activated carbon fiber. Thus, the requirements of hunter clothing may be satisfied. Furthermore, the odors or toxins trying to pass through the adsorption layer may be filtered out, and the requirements of the chemically protective clothing and hunter clothing may be satisfied.Type: ApplicationFiled: November 8, 2002Publication date: May 13, 2004Inventor: Shih-Ju Hsieh

Patent number: 5662993Abstract: The present invention provides a wet-friction material capable of extensive continuous sliding performance at very low slipping speeds without inducing shutter, squawk or chuggle. The present invention includes a friction material having a woven carbon fabric to which a resin, preferably a phenolic resin, has been applied. The phenolic resin is entirely contained within the strand and the strands are intentionally incompletely filled. This combination provides for maximum open area texture for gross flow and drainage, microporosity or microtexture for the destruction of any potential hydrodynamic films and at the same time provides an extremely strong and durable structural composite. The friction material may include an over and under stacking and integration of the less than completely filled strands which is more than adequate for even the severest loading applications.Type: GrantFiled: September 8, 1995Date of Patent: September 2, 1997Assignee: General Motors CorporationInventor: Peter Stanhope Winckler
