Abstract: A dirty water treating apparatus includes a container having air permeability in which a porous material is placed. Aerobic bacteria are implanted onto the porous material. Dirty water is passed through the porous material while air is forcibly passed through the porous material from an air compressor powered by a solar generator. The dirty water treating apparatus is placed in an aquarium in which water is circulated. The apparatus continuously cleans waters, thereby providing an environment suitable for fish.

Abstract: There is provided a small apparatus for disposing of body wastes. The apparatus includes a stirring chamber which is connected to a discharge opening of a toilet bowl, and in which the body wastes and the absorbent are mixed together; and a rotary heating kiln which is formed together with the stirring chamber, and which has a heater for further heating and drying the mixture in the stirring chamber. The body wastes which have been heated, dried and solidified are stored in a storing portion and are collected. Thus, the apparatus is capable of quickly disposing of the body wastes, and of readily handling the solid wastes after the body wastes have been disposed, and of preventing environmental pollution.

Abstract: Personal protective clothing of the present invention is formed into a vest, a skirt, a cap, a coat or the like by using a surface-metallized fiber woven or knitted fabric. A conductive discharging yarn or fabric is electrically connected to the clothing, and a face cover or both a face cover and a backing are attached thereto. The operators of personal computers, word processors and the like can easily wear the clothing for the purpose of protecting their bodies from the electromagnetic waves generated.
