Title: Cooling and heating control device for automatic vending machine
Inventor: TAKIGUCHI KOJI
IPC: G07F9/10
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption while properly maintaining the temperature of vending commodities by detecting the vending of commodities, storing vending state data in each day, determining the running mode of a cooling device or a heating device based on the bending state data of a day of week corresponding to a day concerned out of the stored vending state data, and controlling the cooling device or the heating device in accordance with the running mode. SOLUTION: When solenoid valve 15 is closed by thermostat running, whether a fan 18 is to be stopped or not is judged by a fan stop judging map in accordance with the gross sales of a current day and a pertinent day. When small sales are predicted, the fan 18 is stopped immediately after the stop of the valve 15. Since the lacking of cooling is not almost generated in the case of small sales, the fan 18 is immediately stopped to shorten the running time of the fan 18. Consequently the fan 18 can be efficiently run while preventing the useless power consumption of the fan 18 and the drop of cooling efficiency due to the heating of a fan motor 19.

IPC: G06T7/00
Filed: 1992-12-14
Abstract: PURPOSE:To improve working efficiency and inspection accuracy by automati cally judging an erroneously corrected contour. CONSTITUTION:The rate Ra of the number of bits expressed by values '1' in a binary original picture data D0 to the number of all bits is calculated (S120). Then corrected contour data D2 prepared by manual correcting work using a mouse or the like are vector/raster converted (S170) to prepare raster type new picture data D3 indicating a font having the contour specified by the data D2 as a boundary. Then the rate Rb of the number of bits expressed by values '1' in the data D3 to the number of all bits is calculated (S180). Then the deviation of the rate Rb from the rate R is calculated, and when the deviation is larger than a prescribed value, the defectness of the data D2, i.e., a contour font, is judged (steps S190, S220).
