A drink can induction heating apparatus includes a ferrite core having a plurality of projected portions and recesses formed between the adjacent projected portions. When a drink can is set in a position to be heated, each of the projected portions is oriented toward a longitudinal axis of the drink can and a particular portion of a circumferential wall of the drink can. The apparatus further includes a saddle-shaped heating coil which is partly received in the recesses of the ferrite core and covers a region around the foregoing particular portions of the drink can in a non-contact manner, and an inverter for feeding the AC power to the heating coil. The inverter is arranged to produce the AC power at a resonance frequency which corresponds to one of 5 kHz to 15 kHz where equivalent resistance values of an aluminum can and a steel can approximate to each other.

A film changing apparatus automatically replaces an exposed X-ray film accommodated in a cassette with a new or unexposed X-ray film. Unloading and loading of a film is effected in the vertical direction. Thus, the apparatus saves space in the horizontal direction. Furthermore, unloading of a film from the cassette is effected by gravity, thereby simplifying the structure of the mechanism for changing films, and thus allowing the size of the apparatus to be reduced as a whole.

An anode for generating available chlorine from seawater by electrolysis which comprises a substrate made of titanium or an alloy thereof, and a coating on said substrate which is made up of an active anode material layer containing 15-85 wt % of platinum, 5-35 wt % of iridium dioxide, and 10-15 wt % of ruthenium dioxide. The anode has greatly improved anode performance such as current efficiency, cell voltage, and durability. Therefor, its use for a long period of time becomes possible in any condition of seawater.

A display device according to the invention has a passage between an image generation device (DMD) and a lamp, wherein the passage guides airflow to the vicinity of a reflector of the lamp, and, after the airflow cools the DMD, the airflow can further cool heat generated by a filter which converts light from the lamp to an image light corresponding to video signals of R, G, and B, and by a light pipe which uniformalizes the in-plane intensity distribution of light incident to the DMD.
