摘要： A method for producing a ferroelectric crystal thin film by using a ferroelectric crystal having first and second surfaces opposed to each other and having an etching rate of the first surface higher than that of the second one in a state that the polarization directions are aligned. While applying a predetermined voltage to the ferroelectric crystal, the first surface of the ferroelectric crystal is etched. When the etching progresses and the thickness of the ferroelectric crystal reaches a target value, the directions of polarization of the ferroelectric crystal are inverted and the progress of the enticing automatically stops. Consequently, a ferroelectric crystal thin film extremely thin and uniform in thickness over a wide area can be produced.

摘要： This signal detection method detects an output signal indicating data information contained at least in two sideband waves from an input signal having a carrier and at least two sideband waves accompanying the carrier. The method includes a cut off step (32) for cutting off a sideband wave positioned at the high frequency side or the low frequency side as compared to the carrier from the at least two sideband waves and a square detection step (33) for outputting an output signal by performing square detection of an input signal having one of the sideband waves which has been cut off.
