  • Patent number: 11955959
    Abstract: A parallel driving device that drives parallel-connected semiconductor elements includes a control unit and a gate driving circuit. The control unit detects a temperature difference between the semiconductor elements on the basis of detected values by temperature sensors that detect temperatures of the individual semiconductor elements. The control unit generates a control signal for changing the timing at which to turn on a first semiconductor element specified from the semiconductor elements on the basis of the temperature difference. The gate driving circuit generates a first driving signal for driving the semiconductor elements, and generates a second driving signal that is the first driving signal delayed on the basis of the control signal, and applies the second driving signal to the first semiconductor element.

  • Patent number: 6368668
    Abstract: Disclosed is a method and an apparatus are provided which can efficiently produce a functional material having a satisfactory level of photocatalytic activity. A photocatalyst coating composition comprising a photocatalytic metal oxide and/or a precursor of the photocatalytic metal oxide is coated on the surface of a substrate. The surface of the coated substrate is rapidly heated to fix the photocatalytic metal oxide onto the surface of the substrate. This rapid heating can realize the production of a functional material having a satisfactory level of photocatalytic activity in an efficient manner. The apparatus, which can continuously carry out the rapid heating immediately after the production of the substrate, can produce the functional material having photocatalytic activity in an efficient manner.
