摘要： A compressor which adjusts the pressure of an oxygen-containing gas supplied to a fuel cell system, a throttle valve which controls the flowpath surface area of part of the oxygen-containing gas, and shutoff valves which divide the oxygen-containing gas downstream of the compressor between a fuel cell and reformer, are provided. When fuel vapor absorbed by the canister is purged, the opening of the throttle valve is reduced, and the canister is made to communicate with the upstream side of the compressor. Due to the negative pressure upstream of the compressor, fuel vapor absorbed by the canister is divided between the reformer or a burner, and processed.

摘要： A deterioration diagnosing system for a NOx-occluded catalyst comprises an inlet NOx concentration estimating unit which estimates NOx concentration at an inlet part of the catalyst; an outlet NOx concentration detecting unit which detects NOx concentration at an outlet part of the catalyst; and a deterioration degree judging unit which judges a deterioration degree of the catalyst in accordance with a rate of the minimum value of NOx concentration detected by the detecting unit for a predetermined period to a value of NOx concentration estimated by the estimating unit at the time when the minimum value of NOx concentration is detected. The predetermined period is a period between a time when the engine exhaust gas shows the stoichiometric and/or richer air/fuel ratio and a subsequent time when the engine exhaust gas shows the stoichiometric and/or richer air/fuel ratio.

摘要： Embodiments of the invention a signal processing method capable of realizing low decoding error ratio by using a simple configuration free from unnecessary redundant bits. In one embodiment, user data (512 bytes+additional data) input to an input terminal is RLL-encoded by a RLL encoder 1. The data from the RLL encoder—1 is entered into a symbol error correction encoder where 9-bit symbol encoding is done. Its RS code portion is RLL-encoded by a RLL encoder—2. Signal read from a magnetic disk is entered into a RLL decoder—2 where the RS code portion is RLL-decoded. The signal from the RLL decoder—2 is then entered into a symbol error correction decoder where random read/write errors, burst errors attributable to defects and other errors are corrected to produce a (user data+RLL) signal. This data is output to an output terminal after being decoded by a RLL decoder—1.

摘要： Embodiments of the invention allow relatively simple circuits to provide a coding device capable of coding longer bit-length data suitably for disk apparatus and a decoding device capable of decoding the data coded by the coding device. In one embodiment, a coding device comprises: a coder which, based on an M bits code string, produces an (M+1) bits coded string where each of the plural bits which may appear in the M bits code string is limited in run length; a preprocessor which produces an M bits code string by removing (N−M) bits respectively from predefined (N−M) positions of an incoming N bits code string and outputs the M bits code string to the coder; and a postprocessor which produces and outputs an (N+1) bits code string by inserting the (N−M) bits, which are removed by the preprocessor, into predefined (N−M) respective insertion positions of the (M+1) bits coded string output from the coder.

摘要： A testing device can perform a test on an arbitrary one of a plurality of semiconductor devices by pressing the semiconductor devices onto a contactor from a back side of the semiconductor device. A test circuit board has a contactor provided with contact pieces corresponding to external connection terminals of semiconductor devices to be tested. A support board is capable of mounting the semiconductor devices thereon in an aligned state. A stage supports the support board. A press head presses the semiconductor devices to be tested mounted on the support board so as to cause external connection terminals of the semiconductor devices to be tested to contact with the contact pieces of the contactor. The stage is movable to a position at which at least one of the semiconductor devices to be tested, which are mounted on the support board, faces the contactor.
