A polymer electrolyte fuel cell includes a housing provided with an anode-side supply inlet for supplying a material for fuel, an anode and a cathode accommodated in the housing to sandwich a polymer electrolyte membrane, and a layer containing a biochemical catalyst which decomposes the material for fuel to generate fuel, the layer being formed between the anode-side supply inlet and the anode.
摘要:
In gene expression analysis using DNA chips, the position of a probe on a genome sequence, candidates for splice variants, and the like are displayed in relation to one another. Information on the position of the probe designed for a DNA chip system on the genome sequence is retrieved by connecting to an external database and a server that manage sequence information (genome sequence, mRNA, EST, etc.) and annotation information of various organisms. Further, homologous sequences of a gene for which the probe was designed are detected by homology search program, and the candidates for splice variants obtained from the search are stored in a DNA chip database in relation to expression data.

摘要:
A recording/playback apparatus, includes a supplying device for supplying continuous data at a predetermined transfer rate. A recording device having a certain seek performance and recording mode records the continuous data on the recording medium in a recording unit, and a first setting device sets the size of the recording unit according to the transfer rate of the supplied continuous data or the seek performance of the recording device or the recording mode. The recording device includes a designating device for designating the transfer rate according to the recording mode. The apparatus further comprises a second setting device for setting the number of allowable retries to play back data from said recording medium according to the transfer rate or the seek performance or the recording unit size.

摘要:
The present invention relates to a disk unit or the like capable of improving the reliability of a sector ID-less system and performing rapid frame synchronization. A disk 101 has a plurality of segments (frames) extending in the direction of rotation thereof, each of which has servo regions for recording servo information and data regions for recording user data. A segment ID 105 is recorded in an address region in each servo region in the segment proportions of four to one. The segment ID is a code having information about frame numbers (segment numbers) as viewed from the position of origin and recorded with CRC added thereto. Owing to the detection of the segment ID 105 on the disk 101, the disk unit can rapidly establish frame synchronization, e.g., restrain a reduction in transfer rate used when, for example, data is recorded on both surfaces and reproduced therefrom. Even upon writing, the disk unit can detect out-of-frame synchronization, using the segment ID 105 and shift to an urgent write inhibiting process. Further, erroneous writing developed in the sector ID-less system can be avoided promptly.
