Abstract: A packet communication charge pre-notification system includes a mobile station, a packet communication network containing a mobile communication network connected to the mobile station by radio, and a terminal connected to the mobile station via the packet communication network. The mobile station has a control unit, counting unit, and display unit. The control unit forms packet data from digital data and transmits the packet data to the terminal via the packet communication network in accordance with transmission permission from the user. The counting unit counts the formed packet data before transmission. The display unit displays a communication charge calculated on the basis of the counting result of the counting unit before the packet data is transmitted.

Abstract: Disclosed is a Group II-VI or III-V compound-based single-crystal ferromagnetic material, wherein at least one transition metal selected from the group consisting of V and Cr is substituted for or for the Group II element of a Group II-VI compound selected from the group consisting of ZnTe, ZnSe, ZnS, CdTe, CdSe and CdS, or for the Group III element of a Group III-V compound selected from the group consisting of GsAs, InAs, Inp and GaP, to form a mixed crystal. Further, at least one transition metal selected from the group consisting of V, Cr and Mn is substituted for the Group III element of a Group III-V compound selected from the group consisting of GaN, AlN, InN and BN, to form a mixed crystal. Another transition metal element or n-type or p-type dopant is added to adjust ferromagnetic transition temperature or another ferromagnetic characteristic.

Abstract: A ball catching apparatus such as a baseball glove is disclosed. The apparatus includes a palm-side shell provided on a ball-catching side of the apparatus, a back-side shell provided on a non-ball-catching side of the apparatus, and an extension portion provided at a little-finger base portion of the palm-side shell and connected with the back-side shell. A flexing portion is provided for flexing the extension portion toward the non-ball-catching side of the apparatus.

Abstract: A ball catching apparatus has a a thumb inserting portion and first and second cover members provided on a non-ball-catching side of the apparatus for forming the thumb inserting portion. The first cover member includes an extension portion extending along a direction of inserting the thumb. The second cover member is provided at least around the extension portion. The thumb inserting portion is formed by connecting the first and second cover members to each other at the extension portion, with the first cover member covering at least a portion of the second cover member.

Abstract: An antenna device is withdrawable from and receivable in a body of a portable radio device. A rodlike antenna is covered with a rodlike antenna cover, and a helix antenna to which an initial elastic strain is imparted is covered with a cap. A control portion of an electrically-conductive member is movably received in a groove formed in a portion of connection between the rodlike antenna cover and the cap. The rodlike antenna cover is supported on the body of the radio device. In an extended condition of the rodlike antenna, a connection portion of the electrically-conductive member is urged against the rodlike antenna by a restoring load of the helix antenna to electrically connect the spiral antenna to the rodlike antenna. In a retracted condition of the rodlike antenna, the electrically-conductive member is caused to abut against an antenna holder to be spaced apart from the rodlike antenna, thereby interrupting an electrical connection between the helix antenna and the rodlike antenna.
