Abstract: A washing apparatus includes a washing bath in which articles to be cleaned are washed. The washing bath contains a detergent of a kind containing a nonion surface active agent and a terpene-based solvent as principal components thereof. The articles to be cleaned are, after having been washed in the washing bath, immersed in a rinsing bath containing a rinsing water. The rinsing bath is provided with a recirculating passage extending from a portion of the rinsing bath back to another portion of the rinsing bath, a precision filter disposed on the recirculating passage and having a micro-porous membrane having an average pore size not smaller than 0.01 .mu.m, but not greater than 0.2 .mu.m, and an adsorbent filter containing a mass of activated carbon for substantially purifying the rinsing water which has been passed through the precision filter. The articles to be cleaned are first washed with the detergent of the specified kind and then rinsed within the rinsing bath.

Abstract: In a medical image diagnostic system of this invention having at least an image collecting section, an image storing section, a display section, and an image processing section, the system further includes a determining section and an adding section. The determining section determines an image as an important image when an image derived from the image collecting section and an image stored in and read out from the image storing section satisfy a predetermined important image determining condition when the images are supplied via the image collecting section, image storing section, display section and image processing section. The adding section adds preset identification information to the image which is determined as an important image by the determining section.
