摘要： An inexpensive and reliable thin-film multilayered electrode which is formable on a dielectric substrate such as a ceramic substrate. A thin-film multilayered electrode has thin-film conductors and thin-film dielectrics formed by alternately layering on a dielectric substrate with a predetermined dielectric constant. The dielectric constant for each of the thin-film dielectrics is selected such that the electromagnetic field created in the dielectric substrate and the electromagnetic field created in each of the thin-film dielectrics are substantially in phase with each other when the thin-film multilayered electrode is used at a predetermined frequency, and the film thickness of each of the thin-film dielectrics falls between 0.2 .mu.m and 2 .mu.m; and the film thickness of each of the thin-film conductors, other than a thin-film conductor formed most distant from the dielectric substrate, is thinner than the skin depth at the predetermined frequency.

摘要： The invention relates to a method for producing 3,3-dichloro-1,1,1-trifluoroacetone. This method includes a step of fluorinating pentachloroacetone by hydrogen fluoride in the presence of a fluorination catalyst. This fluorination may be conducted in a liquid phase in the presence of an antimony compound as the fluorination catalyst. Alternatively, the fluorination may be conducted in a gas phase in the presence of a fluorination catalyst which may be a fluorinated alumina or at least one compound of at least one metal selected from Al, Cr, Mn, Ni, and Co. The method is suited to an industrial scale production of 3,3-dichloro-1,1,1-trifluoroacetone. The invention further relates to another method for producing 3,3-dichloro-1,1,1-trifluoroacetone. This method includes a step of purifying a crude 3,3-dichloro-1,1,1-trifluoroacetone by a distillation in the presence of water, thereby to produce 3,3-dichloro-1,1,1-trifluoroacetone which is substantially free of organic matters other than 3,3-dichloro-1,1,1-trifluoroacetone. This crude 3,3-dichloro-1,1,1-trifluoroacetone may be the reaction products of the fluorination of pentachloroacetone in a gas phase. Due to the provision of the another method, 3,3-dichloro-1,1,1-trifluoroacetone can be produced with high yield.

摘要： A thin-film multilayered electrode of a high frequency electromagnetic field coupled type is disclosed. The thin-film multilayered electrode comprises thin-film conductors and dielectric thin films alternately stacked on a dielectric substrate so that a plurality of TEM mode transmission lines are multilayered. A film thickness of each of the dielectric thin films is set so that phase velocities of TEM waves which propagate through at least two of the plurality of TEM mode transmission lines are made substantially equal to each other, and a film thickness of each of the thin-film conductors is set so as to be smaller than a skin depth of a frequency which is used so that electromagnetic fields of at least two of the plurality of TEM mode transmission lines are coupled with each other. The thin-film conductors include at least one adhesive layer having a large adhesion strength at one or more of interfaces between the dielectric substrate and the thin-film conductor and the interfaces between the thin film conductors and the dielectric thin films.

摘要： Trifluoromethyltoluene is obtained from a halomethylbenzotrifluoride, which is a relatively inexpensive material, by hydrogenating the halomethyl group of the starting compound to methyl group with hydrogen gas in the presence of a hydrogenation catalyst and an acid acceptor. Suitable examples of the halomethyl group to be hydrogenated are --CH.sub.2 Cl, --CH.sub.2 F, --CHClF, --CClF.sub.2 and --CF.sub.3. When the starting compound is bis(trifluromethyl)benzene, addition of either an alcohol or an alkali metal fluoride to the reaction system is effective for suppression of formation of xylene as a by-product, and xylene still contained in the reaction product can completely be removed by treatment with a sulfonating agent such as fuming sulfuric acid.

摘要： A vehicular forward-vision display system includes a night-vision camera for scanning a nighttime image ahead of a vehicle and a head-up display for displaying the scanned nighttime image as a virtual image on a front windshield. Luminance of the displayed image is decreased with decreasing vehicle speed. The luminance of the nighttime image is thereby decreased under a low speed where vision aid is not so necessary. This decreasing of the luminance results in giving a driver relief from the bother of being caught by the scanned image displayed on the front windshield.
