    摘要: A printer comprising a printing mechanism, a housing for accommodating the printing mechanism, and a rotatable cover for opening and closing an opening in an upper surface of the housing. The cover has a small opening through which a single sheet of paper printed by the printing mechanism is dischargeable. A rotatable small cover is provided at the small opening for closing and opening the small opening. A receiver which receives the printed sheet of paper when the small cover is open is mounted removably.

    摘要: A treated water quality control system (10) has a sewage inflow estimating unit (1) for estimating an inflow of sewage and a process data storage unit (3) for storing process data on a sewage treatment plant (50). An estimated sewage inflow estimated by the sewage inflow estimating unit (1) and process data read from the process data storage unit (3) are given to a manipulated variable calculating unit (20). The manipulated variable calculating unit (20) calculates values of manipulated variables to be used by a process controller (6) for controlling the sewage treatment plant (50). The values of the manipulated variables calculated by the manipulated variable calculating unit (20) and the process data read from the process data storage unit (3) are given to a process condition estimating arithmetic unit (21). Data on estimated process conditions estimated by the process condition estimating arithmetic unit (21) is given to the manipulated variable calculating unit (20), and then the manipulated variable calculating unit (20) calculates values of the manipulated variables again.
