Abstract: The invention provides a means capable of effectively inactivating and removing allergen or a precursor thereof. The invention relates to an allergen-reducing agent containing water and a water-soluble polymer compound having units having hydroxy or carboxy groups wherein at least a part of hydrogen atoms of the hydroxy or carboxy groups are substituted by specific groups containing a polyether group.

Abstract: A coordinate mutual conversion module is provided which is capable of readily utilizing a global mesh code. A zone number (I-VI) and an east-west number within a block are derived from the longitude of a requested position (S1). A block number and a south-north number are derived from the latitude of the requested position (S2). A unit number is derived from the east-west number and south-north number (S3). The value of the western end longitude of the derived unit is subtracted from the value the longitude of the position to derive the difference which is divided by 2160 seconds (S4), the resulting value is multiplied by 10 raised to n, and an integer part of the resulting value is defined to be an east-west number of a mesh (S5).

Abstract: A determining unit determines whether a terminal is in a communicable state with other terminal via a personal area network. A restricting unit restricts use of the terminal, when the determining unit determines that the terminal is not in the communicable state with the other terminal via the personal area network.

Abstract: A conversion apparatus is connectable to an information processing apparatus which is designed for a device in conformance with a first specification. The conversion apparatus includes a connecting part having a physical shape which enables a device in conformance with a second specification to be connected to the information processing apparatus, a storage to store identification data of the device in conformance with the first specification, where the identification data is read from the storage in place of identification data stored within the connected device in conformance with the second specification when the information processing apparatus makes access to the identification data of the device, and a voltage converter to convert a power supply voltage from the information processing apparatus into a converted power supply voltage in accordance with the second specification to be supplied to the device.

Abstract: In a working environment in which a connection is made between a router device installed in a SOHO and a management division, etc. at a remote location, a router system accommodates multiple user terminals. The router system has a monitoring unit that monitors the communicability state of the user terminals, and an editing communication unit that, when there has been any change in the communicability state of the user terminals, edits and transmits information on the communicability state of the user terminals.

Abstract: To provide a simple process for economically preparing a dihydropyrane compound at a high productivity and a high reaction yield.To use a compound selected from the group consisting of a base and a compound (VIII) having a weaker coordination power to the Lewis acid than the aldehyde compound and having an activity to dissolve the Lewis acid, coordinated by the compound (VIII), in a solvent as a co-catalyst in reacting aldehyde with a diene compound in the presence of a Lewis acid to prepare a 5,6-dihydro-2H-pyrane compound represented by formula (III): ##STR1## in which R.sup.1 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, aryl group which may be substituted with alkyl group, having 6 to 12 total carbon atoms; R.sup.2 and R.sup.3 represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms.
