  • Publication number: 20130142767
    Abstract: The present invention relates to a method of producing reduced coenzyme Q10, including reducing oxidized coenzyme Q10 using a reducing agent in terpenes that can highly dissolve oxidized coenzyme Q10 and reduced coenzyme Q10 in the co-existence of at least one kind of additive selected from the group consisting of alcohols, water, a surfactant and diacylglycerol. In addition, the present invention relates to a composition comprising terpenes, a reducing agent, reduced coenzyme Q10 and at least one kind selected from the group consisting of alcohols, water, a surfactant and diacylglycerol, and a method of stabilizing reduced coenzyme Q10 comprising preparing the composition.

  • Publication number: 20120201802
    Abstract: The present invention aims to provide a component having not only an ability to reduce oxidized coenzyme Q10 and an ability to stabilize reduced coenzyme Q10, but also nutrient, flavor, broad utility and the like, and a utilization method thereof. The present invention relates to a safe and convenient method of producing reduced coenzyme Q10, including reducing oxidized coenzyme Q10 by using, as a component derived from a naturally-occurring substance, which is safe for the body, any one or more components selected from the group consisting of an acerola extract, a tea extract, a rosemary extract, a pine bark extract and a Vaccinium vitis-idaea extract. In addition, the present invention also relates to a method of stabilizing reduced coenzyme Q10 in the co-presence of a component derived from a naturally-occurring substance, and a stabilized composition.

  • Publication number: 20110162301
    Abstract: It is an object to provide a solar cell module having a uniform configuration, presenting stable output characteristics, and having a size enabling easy wiring in arrangement and a solar cell array presenting stable output characteristics by employment of said solar cell modules. A solar cell module 10 has a solar cell panel 12 having a length of its longer edges of 900 to 1100 mm. The solar cell panel 12 is constituted by a number of unit solar cells 100 connected in series and has an open-circuit voltage of 100 to 180 volts. The unit solar cell 100 is of a strip-like shape with a length of its shorter edges of 7 to 12 mm and arranged in a longer-edge direction of the panel 12 so that its longer edges extend in a shorter-edge direction of the panel 12 and its shorter edges extend in the longer-edge direction of the panel 12.

  • Patent number: 6162747
    Abstract: A flame retardant cloth, used for example in interiors as a material for curtains, comprises (A) 60-40 parts by weight of fiber which contains 8-70 wt. % of halogen chemically bonded to a polymer and 1-8 wt. % of Sb compound not chemically bonded to a polymer, and has a shirnkage factor at 240.degree. C. of not less than 40% under a load of 300 mg/metric count yarn count (17), and (B) 60-40 parts by weight of polyester fiber, which compounded making a total of 100 parts by weight. This cloth can retain its high fire retardance even after it has been subjected to a process using a binder, such as pigment printing, and enables the range of application of a compound flame retadant fiber product comprising polyester fiber and halogen-containing fiber to be further widened.
