    摘要: Disclosed is a ceramic composite consisting essentially of hexagonal boron nitride (h-BN), aluminum nitride and, if any, unavoidably formed aluminum oxynitride (AlON), and a sintering aid and/or a reaction product of the sintering aid with the above-mentioned components (h-BN, AlN and AlON), in which the total amount of the sintering aid and the reaction product is 0.01 to 5 parts by weight per 100 parts by weight of the sum of h-BN, AlN and AlON. This sintered body comprises AlN and AlON in a total amount of 45 to 5% by weight with 55 to 95% by weight of h-BN. Alternatively, this sintered body comprises AlN and AlON in a total amount of 80 to 5% by weight with 20 to 95% by weight of h-BN, the degree of anisotropy of the thermal conductivity of the sintered body (the ratio of the maximum thermal conductivity to the minimum thermal conductivity, the direction of the maximum thermal conductivity being perpendicular to the direction of the minimum thermal conductivity) being at least 2.

    摘要: An indicator mechanism in a pushbutton tuner characterized in that there is provided a front plate horizontally extending from the top end of the tuner casing. The front plate is integrally formed with two-stepped protrusions, the lower one of which is inserted in a central bore of a slidable plate mounted on the front plate so that the slidable plate can pivot about the lower protrusion as an axis. The indicator mechanism further comprising a plate spring having an open rectangular configuration for seizing the front plate between its upper and lower plates. The plate spring is also formed with a through bore in its upper plate for receiving the upper protrusion of the front plate. The front plate is further formed with projections as high as the lower protrusion by which the upper plate of the plate spring is supported.

    摘要: Disclosed is a surface-treated precoated metal sheet of which resistance against contamination with a photocatalyst and a self-cleaning function can be retained for a long period. Also disclosed are a method and a surface-treating solution for producing the surface-treated precoated metal sheet properly. The surface-treated precoated metal sheet is characterized by comprising a precoated metal sheet comprising an under metal sheet and an organic resin coating layer provided on the surface of the under metal sheet and a coating film having at least two layers, having a photocatalytic activity and formed on the precoated metal sheet, wherein the coating film having at least two layers comprises an inorganic-organic composite resin composed of a condensed product of an alkoxysilane selected from a group consisting of an alkoxysilane having an organic group selected from a group consisting of an alkyl group having 1 to 12 carbon atoms, an aryl group, a carboxyl group, a hydroxy group and a combination of two or more of these groups, an alkoxysilane having an epoxy group, an alkoxysilane having an amino group, a tetraalkoxysilane and a combination of two or more of the alkoxysilanes and contains a substance having a photocatalytic activity in such an amount that the content of the substance is highest in the outermost layer of the coating film and is gradually decreased toward an inner layer of the coating film.
