Abstract: A garbage treating apparatus for highly efficient garbage treatment without loss in required energy nor requiring continuous control of the treatment is provided by constituting the apparatus for accommodating within a treating vessel a fermentative garbage decomposing agent carrying a microparasite and the garbage, and mixing them for a fermentative decomposing treatment of the garbage through one of a plurality of treating modes mutually selectably changed over in response to sensed moisture content of the resulting garbage mixture sensed by a moisture sensing mechanism.

Abstract: A bubbling bathtub system including both a large bubble generator, which blows relatively large bubbles into a bathtub, and a minute bubble generator, which functions so that bath water with air dissolved therein by pressurization is sent to the bathtub to produce minute bubbles in the bath water, connected to the bathtub. The relatively large bubbles produced by the large bubble generator and the minute bubbles produced by the minute bubble generator cooperate to enhance the good feeling produced during bathing. Both or either of the relatively large bubbles and the minute bubbles can be optionally produced as the user desires for optimum effect.

Abstract: A length composite member comprising a metallic sheet and a rigid synthetic resin coating is bent to be arcuate in transversal section. The thickness of the metallic sheet of such composite member as bent to be arcuate in transversal section is extremely small as compared with the radius of curvature of the desired arcuate sectional curve. A plurality of small arcuate sectional bent portions in transversal section are formed distributed in the transversal or width direction of the metallic sheet. The centers of the respective curvatures of these plurality of small arcuate, sectional bent portions in transversal section are selected to exist on the same side as that of the center of curvature of the composite member bent to be arcuate. The metallic sheet is generally bent in advance to be arcuate in transversal section and both main surfaces of the metallic sheet thus bent are coated with rigid synthetic resin.
