    摘要: A light emitting device has a transparent substrate, a substantially transparent first electrode layer formed on the transparent substrate, a phosphor layer formed on the first electrode layer, a second electrode layer formed on the phosphor layer, an insulating layer formed on the second electrode layer, and a third electrode layer formed on the insulating layer. A hot electron is generated by the application of a voltage to the second and third electrode layers, and the light emitting device is energized to become luminuous by injecting the hot electron thus generated into the phosphor layer.

    摘要: In a flame detecting apparatus for detecting the flame of fire or the like using a sensor 1, a signal processing unit 3 includes a span counting section 5 for dividing a time base into several time spans, each having a predetermined time interval, and counting the number of signals output from the sensor 1 as a count value for each span, a count value storage section 6 for storing the count value for each span output from the span counting section 5, and an calculation section 7 for judging the occurrence of flame by taking into account the count values counted for the past spans which have been stored in the count value storage section 6, as well as the count value of the latest span, when the count value of the latest span is output from the span counting section 5. Because the flame occurrence judgment is preformed by taking into consideration the accumulated values of the preceding spans together with the accumulated value of the latest span, not only strong flame of short duration but also weak flame of short duration can accurately be detected.
