摘要:
Acicular or platy titanium suboxides, expressed by the general formula, TiOx where x is a positive real number less than 2, have a geometric anisotropy as an aspect ratio in the acicular or platy form of 3 or more, a higher specific surface area and a greater geometric anisotropy even in comparison on the basis of the same degree of reduction, and are capable of retaining their native configurations during the reduction. The resin mediums incorporated with the acicular or platy titanium suboxides have good electric properties, and a higher mechanical strength.

A novel and useful automotive wiper device, of which the depression force can be adjusted with a compact mechanism for adjusting the depression force of the wiper blades. The automotive wiper device employes a plurality of springs exerting a biasing force on a wiper arm and a wiper blade against a vehicular window surface. At least one of the springs has an adjustable spring force. The adjustable spring is associated with an adjusting means which allows adjustment of the spring force thereof.

A vehicle lighting device includes at least one lamp unit, a holder that holds the lamp unit in a rotatable manner around a vertical axis, and a drive unit that rotates the lamp unit around the vertical axis.
摘要:
Ultrafine iron-containing rutile type titanium dioxide particles useful for UV shielding cosmetics, pharmaceutical compositions and UV shielding paints are disclosed. They are rutile type crystalline titanium dioxide particles having an average single particle size of 0.01 to 0.1 .mu.m and containing an iron component at a concentration of 1 to 15% by weight as expressed as Fe based on the titanium dioxide in the crystalline structure. They can be produced by using a fine titania sol comprising rutile crystallites as basic particles, precipitating iron oxide or hydrated iron oxide onto the surfaces of the titania particles to effect coating, then firing and grinding.

A method of transmitting a content to a reception side includes the steps of encrypting the content by use of a scramble key that varies with time, encrypting scramble-key-associated information that includes at least the scramble key and usage-control information, the usage-control information indicative of usage of the content on the reception side, and transmitting the encrypted content and the encrypted scramble-key-associated information to the reception side.
摘要:
The invention provides acicular electroconductive tin oxide fine particles which has a mean diameter of 0.005-1 .mu.m and a mean length of 0.05-10 .mu.m and an aspect ratio of 3 or higher. The invention further provides a process for producing the acicular electroconductive tin oxide fine particles, which comprises firing a starting material containing tin, silicon and an alkali metal halide at 700.degree.-1200.degree. C and removing soluble salts from the resulting fired product.

摘要:
Disclosed is a process for producing a titania sol which comprises an aqueous dispersion of finely-divided titania dispersed therein and has a neutral pH range. The process comprises peptizing hydrous titanium oxides with a monobasic acid or salt thereof to obtain an acidic titania sol and removing anions from the acidic titania sol.
