A method for generating an audiovideo report, to be used with a report of radiographic image is disclosed. The catch pan device includes an intercepting pan that intercepts the curtain when coating is stopped and a substantially horizontal intercepting surface that intercepts the curtain only when the catch pan moves to start or stop coating. The collimator may include two or more blocks at least one of which is movable relative to the others. Thereafter, the curing of the moulding material is carried out to form a moulded body having microstructures, which is then removed from the mould and the container. Further, when regenerative braking is applied the current limiter circuit, or a diode buffer in combination with current limiter, serves to prevent charging from creating excessive heat in the additional battery and eliminates the need for a cooling structure in the additional battery.
