Title: Microwave overn with built-in inverter power supply
Inventor: MINAGAWA HIROSHI
IPC: H05B6/68
Filed: 1990-02-16
Abstract: PURPOSE:To finish foods as mentioned in a cooking book even with fluctuations in source voltage by detecting the fluctuation of source voltage, and calculating in response to the detected fluctuation a current value for correcting the fluctuatin of the output of a magnetron, and driving the magnetron through the corrected output current. CONSTITUTION:When source voltage is fluctuated, DC level data detected by a sourve voltage detecting circuit 10 is fluctuated as the source voltage is fluctuated. In response to the fluctuating DC level data a CPU 21 calculates a current value for obtaining the same output as input power at rated operation and power data whose current value is corrected is transmitted to another CPU. The latter CPU extends or shortenes the ON time of a power transistor according to the corrected power data and monitors the fluctuation of an input current using a current level detecting circuit and performs control so that a current input to a magnetron does not fluctuate. Foods are thereby finished as mentioned in a cooking book.

Title: Image reader

IPC: H04N1/10
Filed: 1989-02-17
Abstract: PURPOSE:To detect even a fine step-out by detecting how much a scanner deviates from a specific initial position after scanning and deciding whether or not the deviation is larger than specific deviation where the step-out is judged by a comparing means. CONSTITUTION:A stepping motor is used as a scanner motor 11, so a home position is determined when the image reader is powered on and subsequent control over the scanner is performed numerically by a CPU 25. When however, unexpected load variation occurs, a step-out phenomenon occurs, so sensors 100 and 101 are used to detect abnormality accompanying the step-out, etc. Thus, an image read scanner which scans a document by reciprocal motion relative to the document and judges whether or not the deviation is larger than the value where the specific step-out is judged. Consequently, the value where the specific step-out is judged is properly selected to detect even a fine step-out.
