Abstract: An antenna includes a rod-like core configured by an amorphous metal formed into a bulk configuration, and a coil wound around the core. An electronic device includes a case encasing the antenna, a sectional area of each longitudinal end portion of the core being larger than that of a central portion of the core. The antenna may be disposed under a radio wave permeable decorative plate in such a manner that a magnetic sheet is attached to each end portion of the core to protrude outwards from the core or that an expanded portion is disposed in each end portion and has such a shape to make a side of a surface of the expanded portion facing the decorative plate receive more radio wave than a side of a surface of the expanded portion opposite to the facing surface in relation to an axial line of the antenna.

Abstract: In an antenna device of a wristwatch, a pair of external magnetic members each attached to a respective one of both ends of a magnetic core effectively collects the magnetic flux of a standard time and frequency signal. The collected magnetic flux passes through the core around which a coil is wound, thereby inducing an electromotive force and hence improving the reception accuracy of the signal. The pair of external magnetic members screens out undesirable external magnetism which would otherwise influence motors that drive a hand shaft and hands, thereby achieving accurate hand driving and improving the high watch accuracy.

Abstract: To provide a game program which realizes an increase in realism by reflecting actual weather information in a hypothetical world in a game. A CPU of an apparatus main body obtains actual weather data via a communication interface, and stores it in an HDD. Simulated weather is determined based on a behavioral model which includes the weather data and average year value data recorded in advance in a DVD/CD-ROM. Then, based on the simulated weather determined and parameter correction functions recorded in advance in the DVD/CD-ROM, a character parameter and a background image parameter are corrected, and the actual weather is reflected in an image displayed on a display device.

Abstract: A heat-accumulative material which is a polymer or oligomer having, as a main constituent component, units having a polyether main chain and a side chain, side chains capable of being crystallized, and heat-accumulative composition comprising the same heat-accumulative material. The heat-accumulative material tends to be kept at a constant temperature more effectively by absorbing heat as ambient temperature increases to melt, and releasing heat as ambient temperature decreases to solidify, to moderate changes in ambient temperature, and thereby to exhibit the function as a heat-accumulative material. They have a sufficiently high viscosity, preventing the heat-accumulative material from flowing out even when it is molten. Each of the heat-accumulative material and composition can be made into a heat-accumulative film or sheet, laminate, molded article, composite fiber and cloth which can be suitably used around a body.
