Abstract: An attendance management method according to the present invention comprises: a step in which, at each of a plurality of times a worker starts work during one day, when a computer is operated so as to record the start time or when the computer detects the start of work by the worker, the computer generates a data record for recording the start time and records the start time in the data record generated; and a step in which, when the computer is operated by the worker to record an end time or detects the end of work by the worker, the computer records the end time in the data record in which the most recent start time is registered.

Abstract: The present invention relates to an apparatus for processing fluid for separating any component mixed or dissolved in a fluid and a method for producing a separated fluid. The present invention provides an apparatus for processing fluid which does not require any complicated manifolds in such a way that a plurality of cylindrical vessels each having a plurality of flow ports on the outer peripheral surface thereof at positions near both ends thereof, respectively, and incorporating therein a series of separating elements are arranged substantially parallel to one another with the flow ports of the adjoining cylindrical vessels held connected face-to-face with each other. Further, a method for producing separated fluid at a low cost can be provided by using the above-described apparatus for processing fluid.

Abstract: A plurality of decoders receive digital video data represented by a binary code. The decoders send over a plurality of output lines, the number of which corresponds to the maximum values expressed by the binary code. The decoders provide an output to one of the plurality of output lines in accordance with the binary code. A wired-OR network connects the plurality of output lines with each other. A priority encoder receives signals on the plurality of output lines which are derived from the wired-OR network and encodes them into a binary code in accordance with the one output corresponding to the largest value.
