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.

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.

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.

Abstract: A recess which stores a photovoltaic cell module is provided on the top surface of a tile body arranged on a roof or the like of a house. A fitting section having a groove is formed by undercutting at least one side of the recess. An end portion of the photovoltaic cell module is inserted and fitted into the fitting section. The photovoltaic cell module is therefore detachably fixed in the recess of the tile body.

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.
