Abstract: It is an object of the present invention to provide a novel compound having an antioxidant effect and a technique of using the novel compound. The above object is achieved by providing a compound represented by the following formula (1): wherein any one of R1 to R3 is hydrogen, an acetyl group, a 2-butenoyl group, or a 2-methyl-2-pentenoyl group, each of the other two of R1 to R3 is hydrogen, any one of R4 to R6 is a 2-methyl-2-butenoyl group, and each of the other two of R4 to R6 is hydrogen.

Abstract: A culture medium and a culture medium additive which can promote myogenic differentiation and which contain ergothioneine, ascorbic acid 2-glucoside, ascorbic acid, or a combination thereof. A kit, pharmaceutical composition, food, and drink may also promote myogenic differentiation.

Abstract: A screen-integrated speaker in which mutual interference among channels does not occur easily, a high quality sound and a wide range of frequency are ensured, flexible and light, and downsizing for storage and transport are easy owing to its easiness of rolling up and deployment under a multi-channel structure is provided. The screen-integrated speaker according to an aspect of the invention includes a screen mainly composed of a fibrous structure and an exciter mounted to the back surface of the screen. Preferably, a exciting panel is interposed between the exciter and the screen.

Abstract: There are provided a novel microorganism Enterobacter sp. B20 strain which produces (E)-4-(2-isocyanovinyl)phenyl ?-rhamnopyranoside having a favorable effect of inhibiting melanogenesis and ?-L-rhamnopyranoside produced thereby. This novel microorganism is a gram-negative bacillus isolated from soil and shows motility owing to polar flagellum. The ?-L-rhamnopyranoside, which is produced by culturing the microorganism under aerobic conditions at a culture temperature of 10 to 37° C. and at a medium pH of about 5 to 9 usually for about 1 to 7 days, is useful as a highly safe and stable whitening agent.

Abstract: A method for soldering an electronic component is provided. A first solder land containing copper and a second solder land are formed on a surface of a circuit board. A first solder section composed of a Sn—Ag—Cu solder material is formed on each of the first and the second solder lands, and a terminal of an electronic component chip is mounted on the first solder land. The first solder land and the terminal are fusion-bonded. A second solder section composed of a Sn—Zn solder material is formed on the first solder section disposed on the second solder land. A lead terminal of another electronic component is inserted into a terminal hole formed near the second solder land; and the second solder section and the lead terminal are heated at a temperature lower than the previous temperature to connect the lead terminal to the second solder section by fusion bonding.
