Abstract: PURPOSE:To attain demodulation without entirely being affected due to undershoot in the distortion of a transmitted waveform by constituting '0' or '1' signals by a pair of a 'positive' potential pulse and a 'negative' potential pulse and demodulating either of them. CONSTITUTION:With a signal given to an input terminal 13 and with a clock signal given to a clock terminal 14, a transistor(TR) 17A is turned on and a 'negative' potential pulse is generated across the primary winding of a transformer 18. With the signal reset, a 'positive' potential pulse is generated across the primary winding 18A of the transformer 18 similarly. When a signal is fed from input/output terminals 10, 11 to the primary winding 18A of the transformer 18, a signal appears at one terminal 18-2 of the secondary winding 18B and given to an inverting input (-) of a comparator 232.

Title: Ac load voltage controller
Inventor: KOZAIKU KIYOTO
IPC: H02J3/00
Filed: 1990-02-27
Abstract: PURPOSE:To precisely control an AC load voltage even with a circuit which uses a transformer to detect the load voltage by providing a correcting means which corrects the effective value voltage of the voltage applied to a load in accordance with the power supply phase angle at this time. CONSTITUTION:A microprocessor 4 is the correcting means which corrects the effective value voltage in accordance with the power supply phase angle at such a time. Since the waveform of the voltage is changed between primary and secondary sides of a transformer, the effective value calculated based on the voltage obtained in the secondary side is different from the actual effective value of the voltage of a lamp 10. This calculated value is corrected by the correcting means 4 to obtain the effective value corresponding to the voltage of the lamp on the primary side of the transformer. Two tables for frequencies 50Hz and 60Hz of a power source 1 are provided on a ROM in the processor 4 for the purpose of executing this correction. Correction data are preliminarily calculated correspondingly to respective power supply phase angles and effective values before correction and are registered as fixed values in tables, and the processor 4 refers to tables with fixed values as parameters to obtain required correction data.
