Title: Ice making controller for automatic vending machine
Inventor: HAYASHI TERUAKI
IPC: G07F13/00
Filed: 1995-06-05
Abstract: PURPOSE: To detect the proper remaining amount of ice even if ice making operation is stopped for a long time and to enable normal ice vending by finding the amount of molten ice at specific intervals of time and subtracting the amount of molten ice from remaining ice amount data. CONSTITUTION: A CPU 7 judges whether or not an ice making compressor 3 stops for a specific time and subtracts the specific amount of molten ice corresponding to the stop time from the remaining ice amount data when the stop state is detected. The amount of molten ice in the specific time may be stored in a RAM 8 in advance or calculated by the CPU 7 according to a control program. Then the CPU 7 judges whether or not there is ice left, and then judges whether or not a stirring interval is elapsed when there is ice. When the stirring interval is elapsed, a stirring motor 5 is turned on. Further, it is judged whether or not a stirring time is elapsed, and the stirring motor 5 is turned off when the stirring time is elapsed. Consequently, normal ice vending is possible even if the ice making operation stops for the specific time.

Title: Coordinate detector
Inventor: MAKINO TOSHIYUKI
IPC: G06F3/0488
Filed: 1984-07-04
Abstract: PURPOSE:To reduce an error of coordinate detection with a small amount of correction data and to improve the detecting accuracy, by storing the correction data on the detection error in response to each position of the conductors provided on a tablet in a single period. CONSTITUTION:The level of a detection error due to the distortion of a voltage waveform produced to the conductor set on a tablet 4 repeats the same change for each cycle and produces the same error at the positions corresponding to each cycle. Therefore, the correction data is also equal at the positions corresponding to each cycle. As a result, an error of the detection value can be corrected at each position as long as just the correction data of a single cycle is stored in a ROM8f. The areas shown by oblique lines show the correction data which are stored inthe ROM8f. Thus a coordinate detection error can be reduced with a small amount of correction data. Then the coordinate detecting accuracy is improved.
