Abstract:
A carbon monoxide removing catalyst whose catalytic activity is higher than conventional carbon-monoxide-methanation-reaction catalyst comprising an oxide support containing an oxide containing Co and Zr, and a Ru, Pt, Rh and/or Pd noble metal catalyst loaded on the oxide support, capable of removing carbon monoxide by means of carbon monoxide methanation reaction. The carbon monoxide removing catalyst has higher catalytic activity with respect to carbon monoxide methanation at low temperatures, compared with carbon monoxide removing catalysts which use oxides of Zr—Fe, Zr—Mn, and the like, or zirconia, as the support. A number-of-atom ratio of Co/Zr can be 1/3 or more and 3/1 or less.

Abstract:
A magnetic member is interposed and arranged between an antenna element and a printed circuit board, and an air member or a dielectric member is interposed between the antenna element and the magnetic member. The magnetic member is constituted of a nanogranular structure in which magnetic nanoparticles with ferromagnetism are three-dimensionally dispersed and arranged in an insulating matrix substrate.
Abstract:
To provide a technique by which, if the number of active disk groups in a storage device is restricted, an appropriate logical volume in the storage device can be used. A management apparatus manages a storage device provided externally. The management apparatus obtains management data indicating which of a plurality of disk groups included in the storage device is active, from the storage device. In addition, the management apparatus executes predetermined processing with reference to the management data in order to utilize a logical volume belonging to a disk group in the storage device while ensuring that the number of active disk groups in the storage device does not exceed an upper limit value.
Abstract:
A data storage system includes a first data storage medium for storing data, the first data storage medium currently configured as an accessible medium; a second data storage medium for storing a copy of the data, the second data storage medium currently configured as a standby medium; first configuration information defining a switching trigger when the first data storage medium currently configured as the accessible medium becomes the standby medium and when the second data storage medium currently configured as the standby medium becomes the accessible medium; and a data storage system manager using the first configuration information to control the switching. The first data storage medium and second data storage medium may each be in a power-saving state. The accessible medium thus may be in a power-saving mode. The standby medium thus may be in a power-saving mode or in a power-off mode. The accessible medium may be read-only. The switching trigger may be a time period, an equation of access time or an administrative request. There data storage system may include additional data storage media for storing additional copies of the data, the additional data storage media also configured as standby media.
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:
There is provided a radio apparatus usable in a frequency band of use comprising a feeder circuit, a first antenna element and a second antenna element. The first antenna element having a first end connected to the feeder circuit and a grounded second end includes a forward path and a backward path short-circuiting to each other at a shorting bridge, and is a half wavelength long of a first frequency in the band of use. The distance between the first end and the second end is no greater than one-tenth wavelength of the first frequency. The second antenna element begins with the first end, shares a part of the forward path with the first antenna element, diverges from the forward path at a diverging point before the shorting bridge, comes to an open end and is one-fourth wavelength long of a second frequency in the band of use.
