Near-infrared and Mid-infrared Spectroscopy with the Infrared Camera (IRC) for AKARI
The Infrared Camera (IRC) is one of the two instruments on board the AKARI
satellite. In addition to deep imaging from 1.8-26.5um for the pointed
observation mode of the AKARI, it has a spectroscopic capability in its
spectral range. By replacing the imaging filters by transmission-type
dispersers on the filter wheels, it provides low-resolution (lambda/d_lambda ~
20-120) spectroscopy with slits or in a wide imaging field-of-view
(approximately 10'X10'). The IRC spectroscopic mode is unique in space infrared
missions in that it has the capability to perform sensitive wide-field
spectroscopic surveys in the near- and mid-infrared wavelength ranges. This
paper describes specifications of the IRC spectrograph and its in-orbit
performance.Comment: 13 pages, 7 figures, accepted for publication on PAS
A Case of Transient Rise of Pacing Threshold during the Chronic Phase of Pacemaker Implantation
We experienced a case of pacing failure with transient rise of the pacing threshold more than one year after implantation. Neither the generator nor lead system was found to be defective. During the antibiotics therapy to treat cholecystitis, which was found on admission, pacing failure was improved. The clinical course suggested that the infection was related to the improvement, although accurate mechanisms were unknown
