Abstract: The coating composition which coats the biologically active substance includes at least one protective material selected from the group consisting of a hardened animal fat, a hardened vegetable oil, a linear or branched, saturated or unsaturated aliphatic monocarboxylic acid having 12 to 22 carbon atoms, a fatty acid ester, and a wax group; lecithin; and at least one preservative selected from a propionic acid or its salt, a sorbic acid or its salt, a benzoic acid or its salt, a dehydroacetic acid or its salt, parahydroxybenzoic acid esters, an imazalil, a thiabendazole, an orthophenyl phenol, an orthophenyl phenol natrium, and a diphenyl.

Abstract: A wireless microphone transmits audio signals using infrared rays. A plurality of infrared light emitting devices are attached to a board in the wireless microphone, and at least one of the plurality of infrared light emitting devices is disposed on each side of the board. A plurality of infrared light emitting devices may be provided on each side of the board, and the infrared light emitting devices may be disposed radially. Without providing a different dedicated board for the light emitting devices than the board, infrared rays can be radiated to an area around the mic. In this manner, a wireless microphone is provided that can radiate infrared rays to an area around the mic and that has a simple structure and a small number of components and thus can improve productivity.

Abstract: A video signal processing apparatus includes an A/D converter for converting an analog video signal to a digital video signal. Also included is a 3-dimensional scanning line interpolating unit for outputting an original video signal and an interpolating signal which is synchronized with the original video signal and which includes interpolated scanning lines. A magnification processing unit and a switching signal generating unit are also provided. The switching signal generating unit is for generating a switching signal corresponding to a vertical magnifying power. Further, a switching unit is included for switching between the original video signal and the interpolated video signal according to the switching signal and for outputting the switched signal.
