摘要:
Potassium hexatitanate fibers having a tunnel structure and a free potassium content of 5 ppm or less can be produced by mixing together a titanium containing compound and a potassium containing compound in a ratio represented by the formula K.sub.2 O.nTiO.sub.2 (wherein n=from 2 to 4); firing the mixing at 900.degree. to 1,200.degree. C. to produce mass of potassium titanate fibers; dipping the mass of product in either cold or hot water to disintegrate the mass of potassium titanate fibers into individual single fibers; adding an acid to the slurry to adjust the pH value to 9.3-9.7, thereby changing the composition of the potassium titanate fibers so that the molar ratio of TiO.sub.2 /K.sub.2 O is in the range of from 5.95 to 6.00; heating the fibers at 950.degree. to 1,150.degree. C. for 1 hour to more; and washing the fibers with an acid. The potassium hexatitanate fibers, which have minimal free potassium content, i.e., 5 ppm or less, can be suitably used as a reinforcing material for polyester thermoplastic resins, polyphenylene sulfide resins, liquid crystal polymers, aluminum alloys, magnesium alloys and so forth, all of which are easily affected by free potassium.
摘要:
Lustrous flaky red iron oxide pigments containing aluminum in solid solution are produced by applying hydrothermal treatment to iron oxyhydroxide or colloidal precipitates of a ferric hydroxide in an aqueous aluminate solution. Lustrous pigments exhibiting various colors different from those of titanium dioxide-coated mica pigments are produced by coating titanium dioxide hydrate or titanium dioxide on the surface of the grains of flaky red iron.
摘要:
Synthetic yellow iron oxide (.alpha.-FeOOH) is dispersed in an aqueous ferric solution, and an adequate alkali solution and an aqueous aluminum salt solution are added. The resultant dispersion is subjected to a hydrothermal treatment at 150.degree.-250.degree. C. By this treatment, the surface of the synthetic yellow iron oxide is covered with a (FeAl)OOH (solid solution). Yellow iron oxides treated thus have an elevated resistivity to heat of about 50.degree. C. The modified synthetic yellow iron oxide thus obtained is non-toxic and can be used as a pigment in plastics and melt-type traffic paint.
摘要:
A control apparatus is provided with a substrate disposed inside a main case and on which light sources are mounted. A surface panel in which light-source display windows are formed at positions opposite the light sources, is also disposed in the main case. The outer rim of the surface of the surface panel facing the main case is affixed to the front-surface rim of the main case with an insulating part sandwiched therebetween.
摘要:
There is provided a pressure sensor having: a sensor chip (30) which detects a pressure; a base plate (20 (21, 22)) which supports the sensor chip (30); and a support diaphragm (50) which is bonded to the base plate (20 (21, 22)) and supports the base plate (20 (21, 22)), wherein the pressure sensor (1) has a structure in which the support diaphragm (50) is joined to a package (10), and the sensor chip (30) and the base plate (20 (21, 22)) are supported in the package through the support diaphragm (50) alone, thereby constantly and accurately detecting a pressure without being affected by a heat stress caused due to heat from the outside.
