Abstract: A control arrangement for an automatic vending machine includes a price memory device for preliminarily storing selling prices of commodities, a coin signal output section for outputting coin signals upon insertion of coils, a sum calculating device for calculating a sum of inserted coins in response to the coin signals, a difference calculating device for calculating a difference between the sum of the inserted coins and the selling price, a device for calculating the required number of coins for change by dividing the difference by the sum of coins of the same denomination, and a device for judging vendibility at the selling price based on whether or not the required number of coins for the change is present. In this way, the vendibility of all commodities may be determined according to their selling prices without successively subtracting the value of change to paid out for each increment of selling price, and prior to the actual vending of the commodity.

Abstract: An air conditioner comprises a control portion and a refrigeration system wherein a compressor, a condenser, an expansion device and an evaporator are connected in a refrigerant flow relationship. The control portion compares the temperature measured by a room temperature sensor with the temperature set by a temperature setting switch. For heating, the compressor is stopped when the room temperature rises higher than the set temperature, and for cooling, the compressor is stopped when the room temperature falls lower than the set temperature. A special switch is installed in the control portion, and when this switch is operated, responsively the range of the temperature set by the temperature setting switch is changed. More specifically, when the switch is operated at heating the control portion lowers the upper limit of the temperature set by the temperature setting switch and at cooling, the lower limit of the temperature is heightened by the control portion.
