  • Patent number: 10291020
    Abstract: An overvoltage protection device includes a resistor that is connected in series between an internal signal line connected to a communication terminal of a processor and a communication line, a diode of which a cathode is connected to the internal signal line and an anode is connected to a ground, and a PNP transistor of which a base is connected to a power supply terminal, an emitter is connected to the internal signal line, and a collector is connected to the ground. When a base-emitter voltage (a junction saturation voltage) of the transistor in operation is defined as VBE and a power source is turned on (a voltage V1) by the operation of the transistor, a voltage of the internal signal line is limited to the source voltage V1+VBE. When the power source is turned off (a voltage 0 V), the voltage of the internal signal line is limited to the source voltage 0 V+VBE.

  • Patent number: 8985342
    Abstract: Provided is a color sorting machine in which decreases in yield resulting from the erroneous inclusion of good granules can be prevented by using different selection algorithms and operation ejector nozzle operations resulting therefrom in a first sorting part and a second sorting part. The machine is provided with: a binarization means for binarizing images of granular objects, a flaw-detecting means for extracting flawed parts of granular objects, a reducing means for reducing images of the external contour parts of granular objects, an enlarging means for enlarging images of the flawed parts of granular objects, and a synthesis means for synthesizing the reduced images of the external contours and the enlarged images of the flawed parts; wherein on the basis of an image obtained by this synthesis means, different air-jetting operations are established for the ejection means of a first sorting part and the ejection means of a second sorting part.
