A USB socket is a receptacle for a directional USB plug including a male tongue provided with a first electrode terminal, and has first and second female tongues and a casing. The first female tongue has a second electrode terminal electrically connected to the first electrode terminal when the USB plug is inserted in a regular orientation, and is pushed with the male tongue in a direction of insertion when the USB plug is inserted in an inverted orientation. The second female tongue is pushed with the male tongue in the direction of insertion when the USB plug is inserted in the regular orientation, and has a third electrode terminal electrically connected to the first electrode terminal when the USB plug is inserted in the inverted orientation. The casing houses the first and second female tongues such that the second and third terminals are face with each other.

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.

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.

An extreme pressure agent and a friction coefficient modifier which comprises a compound having, in a molecule, a group represented by general formula (I): ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 each represents hydrogen atom or methyl group, and at least one of R.sup.2 and R.sup.3 represents hydrogen atom; a fluid resistant to seizure under load and a wear resistant fluid which each comprises the above additive or the above modifier; and a flame resistant fluid which comprises a thermally polymerizable substance, preferably the above compound. The extreme pressure agent and the friction coefficient modifier have excellent properties and are advantageously used for lubricating oil, metal working oil, and hydraulic oil. The flame resistant fluid suppresses vaporization of flammable substances by thermal polymerization to prevent fire when the fluid is exposed to a high temperature and is advantageously used as lubricating oil, metal working oil, hydraulic oil, heat treatment oil, and grease.

An antenna device includes an antenna for receiving a time information radio wave, and an antenna support member. In the antenna, a coil is wound around a center portion of a core. In the support member, a non-magnetic portion supports two magnetic portions independently and both end portions of the core of the antenna are magnetically coupled with the magnetic portions. A radio wave controlled timepiece includes a case in an inner space of which the antenna and the support member are installed as described above. In the inner space, a time counting unit, a time display unit connected to the time counting unit, and a time updating unit configured to update the time displayed on the display unit, based on the time information radio wave received by the antenna, are installed.
摘要:
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.
