Caprazene and caprazol could be synthesized by hydrolysis of a caprazamycin. There could be synthesized a caprazene-1′″-amide derivative of the formula (II) and a caprazene-1′″-ester derivative of the formula (III) from caprazene. Further, there could be synthesized a caprazol-1′″-amide derivative of the formula (V) and a caprazol-1′″-amide-3′″-ester derivative and a caprazol-3′″-ester derivative, etc. from caprazol. Furthermore, an imidazolidinone derivative could be synthesized from the ring-opened product of the 1,4-diazepinone ring of caprazol. The novel caprazene derivative, novel caprazol derivative and novel imidazolidinone derivative now synthesized exhibit excellent antibacterial activities against a variety of bacteria, including acid-fast bacteria.

摘要:
An electroluminescent element (10) is provided with: a lamination section in which a first conductive layer (12), a dielectric layer (13), a second conductive layer (14), a light-emitting layer (15) and a third conductive layer (16) are laminated in order; and contact holes (17) for at least penetrating through the dielectric layer (13) and electrically connecting the first conductive layer (12) and the second conductive layer (14). When viewed from the light-emitting surface side, the electroluminescent element (10) (i) has at least one continuous light-emitting region, and (ii) the number of contact holes (17) is 102 or more per one light-emitting region and such that the ratio of the area of the contact holes (17) to the area of the light-emitting region is 0.1 or less. Thus, it is possible to provide an electroluminescent element, etc., that is easily manufactured and has high light emission uniformity.
摘要:
Micro-bubble generators attached to a ship hull below the waterline decrease frictional resistance during navigation and improve fuel efficiency. Each micro-bubble generator is supplied with air and has a wing positioned outside the hull for generating negative pressure. The negative pressure created by the wing increases with an increase in ship's speed, which pushes the air-liquid interface outwardly toward the wing. As the air and the water move at different speeds due to difference in their densities, micro-bubbles are generated in the micro-bubble generator according to the Kelvin-Helmholtz Instability mechanism and discharged downstream to move closely along the outside surface of the hull.

摘要:
[Object] The present invention provides for a frictional resistance reduction ship able to decrease friction resistance and improve fuel efficiency.[Solution] When the navigation speed increases, and negative pressure which is created by the wing 33 increases, a result is that the air-liquid interface is pushed down further. Due to the air and the water (sea water) moving different speeds, density differs between air and water (as shown in FIG. 7), micro-bubbles are generated in the micro-bubble generator according to the Kelvin-Helmholtz Instability mechanism, and these micro-bubbles flow through onto the downstream side along the hull.
