Abstract:
In an antenna device, a half wavelength dipole antenna is folded so as to form a forward path section, a folding section and a backward path section such that the backward path section is connected to the substrate at the ground terminal, and an electric power is supplied from the power supply source at the branching point, so as to configure a folded monopole antenna. Also, an additional antenna is folded similarly and connected to the monopole antenna such that the branching point and the power supply section are shared by the monopole antenna and the additional antenna.

Abstract:
A method and apparatus which provide solutions for avoiding journal overflow in after and before journal methods of a backup and recovery system used with a storage system. The after journal method solutions, which are conducted when the amount of free space reaches a threshold, include periodically taking a new snapshot and deleting the oldest journal, periodically taking a new logical snapshot and deleting the oldest journal, stopping the taking journal entries when the journal volume is full, and stopping the taking journal entries when the journal volume is full and then switching to bitmap management. The before journal method solution, which is conducted when the amount of free space reaches a threshold, includes applying wrap-around overwriting to overwrite the oldest journal entry by the newest journal entry.
Abstract:
An antenna is shaped to include a substantially 1-wavelength loop portion and a pair of dipole portions. The loop portion includes vertical portions, which are located opposite to each other in a vertical direction. The dipole portions share part of the loop portion, and are located opposite to each other in a horizontal direction.
Abstract:
It is an assignment to provide a carbon monoxide removing catalyst whose catalytic activity is higher than conventional carbon-monoxide-methanation-reaction catalyst. It is characterized in that it comprises an oxide support composed of an oxide containing Co and Zr, and a noble metal catalyst selected from the group consisting of Ru, Pt, Rh and Pd, and loaded on the oxide support, and it can remove carbon monoxide by means of carbon monoxide methanation reaction. A carbon monoxide removing catalyst of the present invention is such that such an effect is available that the catalytic activity with respect to carbon monoxide methanation reaction is higher when being low temperatures, compared with carbon monoxide removing catalysts which use oxides of Zr—Fe, Zr—Mn, and the like, or zirconia, as the support. In particular, it is desirable that a number-of-atom ratio of Co/Zr can be 1/3 or more and 3/1 or less.

Abstract:
A mobile communication terminal of a portable telephone is housed in a casing having a first surface. A receiver section of the portable telephone capable of generating a voice is arranged on the first surface. A two-wavelength loop antenna arranged on a plane substantially parallel to the first plane and formed of a looped line having a right section and a left section that are in symmetry with respect to an imaginary vertical symmetric line is housed in the casing. A power supply point for supplying an electric power to the loop antenna is arranged in the vicinity of the intersection between the symmetric line and the looped line.
