Patent number: 7374804Abstract: An optically readable media (10) has an information-encoding layer (16) and at least one color-forming layer (12) that embodies an optical readout-limiting mechanism. In a first embodiment the at least one color-forming layer contains an additive that does not interfere with the optical readability of the media for a duration of a readout period.

Patent number: 7374840Abstract: This invention relates to centrifugal atomized zinc alloy powders for alkaline batteries consisting of (a) 0.005-2% by weight of indium, and 0.005-0.2% by weight of either one of Al and Bi, or (b) 0.005-2% by weight of indium, and 0.005-0.2% by weight of Bi, and 0.001-0.5% of either one or both of Al and Ca, or (c) 0.005-2% by weight of either one or both of Bi and Al, and 0-0.5% by weight of Pb, the remainder being zinc. The powder is obtained by centrifugal atomisation in a protective atmosphere, where the oxygen content is less than 4% by volume. The resistance to corrosion in the electrolyte of the battery, especially after partial discharge, is markedly better than when the same alloys are prepared by the traditional production process. The capacity of batteries containing these powders is very good.Type: GrantFiled: February 3, 2000Date of Patent: May 20, 2008Assignee: UmicoreInventors: Yvan Strauven, Bruno Gay

Patent number: 7374842Abstract: A non-aqueous electrolyte secondary battery, comprises positive and negative electrode plates, each comprising a current collector and a material mixture layer carried on each face thereof. A total thickness of the positive electrode material mixture layers on both faces of the current collector is 40 ?m to 100 ?m. The positive electrode plate has an electrode area of 520 cm2 to 800 cm2 per battery capacity of 1 Ah. The negative electrode material mixture layer comprises a graphitizable carbon material. A wide-range X-ray diffraction pattern of the graphitizable carbon material has a peak PX (101) attributed to a (101) crystal face at about 2?=44 degrees, and a peak PX (100) attributed to a (100) crystal face at about 2?=42 degrees. A ratio of an intensity IX (101) of PX (101) to an intensity IX (100) of PX(100) satisfies: 0<IX (101)/IX (100)<1.Type: GrantFiled: April 28, 2004Date of Patent: May 20, 2008Assignee: Matsushita Battery Industrial Co., Ltd.Inventors: Yoshiyuki Ozaki, Kazuhiro Ota, Junichi Yamaura, Takabumi Fujii
