Abstract: Signal input units 105a to 108a of antenna elements 105 to 108 are held on the essentially same circumference. Signal output units 113b, 113c, 114b, and 114c of a feeding circuit 102 are held on a line which is located perpendicular to a plane where the above-described circumference is located, and also which passes through an essential center of this circumference. The feeding circuit 102 supplies feeding signals to the antenna elements 105 to 108 while applying predetermined phase differences to these feeding signals. As a result, electric lengths of feeding lines 119A to 119D are made coincident with each other. These feeding lines are to connect the signal output units 113b, 113c, 114c to the signal input units 105a to 108a.

Abstract: A self-refresh apparatus for a semiconductor memory device is disclosed. According to the self-refresh apparatus, Data loss can be prevented by monitoring a leakage of memory cell data, activating a variable self-refresh signal in accordance with a signal resulted from the monitoring during a self-refresh mode, producing a refresh request signal when the self-refresh signal is activated and then refreshing all of memory cells. An unnecessary power consumption can be also prevented by variably performing the refresh operation in accordance with the retention time of cell data.

Abstract: Acid water containing hypochlorous acid is produced by an anode chamber of an electrolytic chamber, and alkali water is produced by a cathode chamber. The acid water is reserved in a reservoir tank and is returned into the anode chamber by actuating a return pump. The acid water returned into the anode chamber is subjected to further electrolysis, and fed in the cathode chamber through a first water supply line, an interconnection means and a second water supply line, so as to sterilize the interiors of the first water supply line, the interconnection and the second water supply line.
