摘要： A dehydration method by which water is selectively separated from a water-containing mixture 31 with a separation membrane. The separation membrane is a DDR type zeolite membrane 2. The dehydration method includes bringing the mixture 31 into contact with one side of the DDR type zeolite membrane 2 and causing a pressure difference between that side of the DDR type zeolite membrane 2 which is in contact with the mixture and the other side of the DDR type zeolite membrane 2 to thereby cause the water to selectively permeate and separate out. By the dehydration method, water can be selectively separated from a water-containing mixture without the need of a high energy cost. The separation membrane has excellent acid resistance.

摘要： Switching functions of an electronic timepiece including switching for time amendment, are controlled by a stem which is rotatable and axially movable. When in neutral axial position, the stem is rotatable to display alternatively hours, minutes and seconds or month and date. When pulled out to its outer axial position, the stem is rotatable in one direction to select the time function (hours, minutes, month or date) to be amended and is rotatable in the opposite direction to supply pulses from a dividing circuit to the counter of the selected time function to effect the desired amendment. When pushed in to an inner axial position, the stem actuates which means to illuminate the time display.
