Abstract: A garbage disposal for decomposing garbage with microorganisms. The garbage disposal has a tank containing a mixture of garbage, a medium having microorganisms, stirring means for stirring the mixture in the tank in order to supply air into the mixture, and control means for controlling water content percentage of the mixture. The control means controls a stirring of the mixture and/or a temperature of the mixture and/or an air volume blown on the mixture in order to keep water content percentage in a proper value at which the microorganisms are active and a lifetime of the medium is extended.

Abstract: A commodity delivering device for automatic vending machines in which both thick commodities and thin commodities are sorted out automatically without manually adjusting the commodity passage width. The automatic vending apparatus includes: a commodity feed mechanism in which the commodity mechnism is equipped with: first stopper for freely switching between an activation position and a no-activation position, the activation position thereof being projected into a commodity passage so as to support the thick commodity and the no-activation position being retreated from the commodity passage; second stopper, disposed right under the first stopper, for freely switching between an activation position and a no-activation position; and feed stopper for switching between an activation position interlocked with the first or second stopper so as to thereon support the commodity, and a feed position for transferring the commodity downward.

Abstract: An automatic vending machine for automatically vending commodities comprises at least one storage unit for storing the commodities, at least two discharge paths downwardly branched from the storage unit, for discharging the commodities, and a feed unit for opening and closing the two discharge paths alternately for feeding the commodities one by one from the storage unit.
