  • Patent number: 6414854
    Abstract: In a power conversion apparatus using a semiconductor switching element, a collector-emitter voltage detecting device is provided to detect the collector-emitter voltage in the semiconductor switching element in the power conversion apparatus in order to comprehensively reduce switching loss and conduction loss arising in a switching element. A base current supplied to the switching element is controlled based on the detected collector-emitter voltage so as to control the collector-emitter voltage or control a regenerative power to be transmitted from a switching element driving power supply to an external auxiliary power supply or the like. This provides an optimum driving in consideration of factors including dispersion in a specific current amplification factor (hfe) of the switching element, variance in the hfe caused by temperature, and variance in the hfe to a current flowing through the switching element, for reducing a sum of conduction loss and driving power of the switching element.

  • Patent number: 6400473
    Abstract: This invention provides an image reader which simply fetches a film image as an image of substantially the same size and the same image quality irrespective of issuance of a trimming command. In the image reader, information related to a trimming area can be read from a developed film by use of a magnetic information reading circuit. Further, light is applied to the developed film and image information is read based on light transmitted therethrough by use of an image input circuit. The resolution set when the image input circuit fetches image information from a preset trimming area is determined by a control circuit based on trimming information from the magnetic information reading circuit.
