Abstract: A mobile phone terminal acquires and stores therein current position information thereof from a public wireless base station. The mobile phone terminal reads out a profile name corresponding to the acquired position information from a public wireless base station WLAN profile association table, and sets the read WLAN profile as a scan profile. Then, the mobile phone terminal scans the wireless LAN access point with the set WLAN profile when the mobile phone terminal is out of the WLAN service area.

Abstract: When the presence of an RF ID tag is detected by a contactless reader/writer, an information processing terminal causes a contactless reader/writer to set a state flag in the RF ID tag to a first state which indicates that a wireless LAN communication unit of the mobile telephone is in an inactive state, and sends presence information indicating the presence of the mobile telephone to the information processing apparatus. When the state flag in the RF ID tag is set to the first state, the mobile telephone disables the wireless LAN communication unit. The information processing apparatus receives the presence information and stores the received presence information in a database.

The incident surface has flat planes among the projections or depressions.

Abstract: In etching of silicon nitride with a phosphorus type, if etching is carried for a long time, silicon oxide tends to precipitate, and it has been impossible to constantly carry out the etching for a long period of time. By an etching method for silicon nitride using a composition comprising a phosphorus compound, a boron compound, a silicon compound and/or their fluorides thereof, there will be no precipitation of silicon oxide even when the composition is used for a long time. It is particularly preferred to further add nitric acid and/or a nitrate, whereby stability of selectivity will be increased.

Abstract: Cleaning compositions composed of specific amounts of carbonic acid and/or carbonate, hydrogen peroxide, aluminum fluoride and water are highly effective for cleaning electronic devices of resist, resist residues, titanium dioxide, aluminum oxide and silicon dioxide. The compositions contain no hydroxylamine and are thus free of its hazards.
