Abstract: Conventional ozone water is still insufficient in the removal rate and cleaning ability of resist required in today's semiconductor manufacturing field, and it does not fully meet the expectation of further improvement in the effects of sterilization, deodorization, and cleaning in the fields such as cleaning of foodstuffs, cleaning of process equipment and tools, and cleaning of fingers, as well as in the fields such as deodorization, sterilization, and preservation of freshness of foodstuffs. The above-problem can be solved by defining the values of a plurality of specific production parameters in the production of ozone water into specific ranges.

Abstract: In a transceiver, on a top surface of a rectangular plate-shaped substrate, transmission radiating elements and receiving radiating elements are provided. The transmission radiating elements extend in the horizontal or lateral direction from the center of the substrate. The receiving radiating elements extend in the vertical or longitudinal direction from the center of the substrate. Inductors included in a matching feeding element are individually electromagnetically coupled to transmission-side feeding points that are inner end portions of the transmission radiating elements and receiving-side feeding points that are inner end portions of the receiving radiating elements. A transmission signal is transmitted with a wave polarized in the horizontal or lateral direction, and a signal having a vertical or longitudinal polarization direction is received.

Abstract: Four generally quadrant-like indentations are formed at the corners of a substrate. A conductive member is applied to the inner surfaces of the indentations to form input and output terminals, namely a power voltage terminal, a voltage control terminal, a modulation terminal, and an output terminal. By placing these terminals at the corners of the substrate, sufficient distances are provided between the input terminals and the output terminals so as to prevent interference between these terminals.
