摘要： High-accuracy overcurrent detection is performed, while a loss resulting from the current detection is significantly reduced. A switch section outputs the voltage between the both terminals of a current detection resistor using an AND signal between an output signal from a hysteresis comparator and an output signal from a pre-driver. The voltage is filtered by an electrostatic capacitor element and a resistor, and inputted to a comparator. The comparator makes a comparison between the signals inputted to the two input terminals thereof, and outputs the result of the comparison to a digital filter. When an overcurrent begins to flow in a power supply unit, the levels of the voltages inputted to the two input terminals of the comparator are inverted so that the comparator outputs an inversion signal to the digital filter. The digital filter outputs a detection signal to an overcurrent detection circuit when an arbitrary time has elapsed.

摘要： A heating apparatus in which an object to be heated placed in its heating chamber can be heated until the surface of the object is charred as desired by the user. A first photo sensor senses the intensity of light of visible spectrum range directed toward and reflected from the surface of the object being heated, and a second photo sensor senses the light intensity related to the light reflected from the surface of the object, that is, at least one of the intensity of illuminating light emitted from a light source and the intensity of illuminating light coming from the exterior of the heating chamber. The degree of charring of the surface of the object is judged on the basis of the output signals from the first and second photo sensors, and the heating operation is controlled on the basis of the result of judgement.

摘要： A cooking heating apparatus is provided in which an object to be heated is subject to char cooking, the apparatus having a detector circuit for detecting the charred condition by detecting the intensity of reflected visible light from the surface of the object and a heating device for burning and removing foreign materials created upon heating the object and deposited on a transparent glass which is provided for preventing the foreign materials from reaching a light source which provides the visible light and a photosensor which detects the reflected visible light. The apparatus may further comprise means for forcing off the foreign materials burnt by the burning and removing elements by means of a forced air flow and/or a device for scattering the foreign materials given off from the object upon heating to prevent the foreign materials from reaching the transparent glass.
