A dial, an LED, a black print film and a liquid crystal display panel are provided. A non-black print region where the black print film is absent is provided in, of a back surface of the dial, a circumferential part surrounding an opening and including an inner edge defining the opening.

Instrument for vehicle

A spindle motor () is composed of a base (), a sleeve () in cylindrical shape that is fixed on the base (), a shaft section () inserted into a through hole () of the sleeve () that is rotatable with respect to the base (), a hub () that rotates together with the shaft section (), a radial dynamic pressure bearing section (RB) formed between a bushing () and the sleeve (), a flange section () that protrudes in a radial direction on an outer circumferential section of the sleeve (), a wall section () in annular shape that protrudes with surrounding the sleeve (), a thrust ring () that is fixed on an inner circumferential section of the wall section () being adjacent to the flange section () and the bushing () in an axial direction, and a seal plate (fixed on an outer circumferential section of the sleeve () with sandwiching the thrust ring () between the flange section () of the sleeve () and the seal plate () in an axial direction. The spindle motor () is furnished with a first thrust dynamic pressure bearing section (SB), which is formed between confronting surfaces () of the thrust ring () and the flange section (), and a second thrust dynamic pressure bearing section (SB), which is formed between confronting surfaces () of the thrust ring () and the seal plate ().

Hydantoin derivatives and herbicides containing said derivatives as

4-imino-oxazolidine-2-one derivatives, a process for producing such

The present invention relates to 3,4,5,6-tetrahydrophthalamide derivatives and 3,4,5,6-tetrahydroisophthalimide derivatives having excellent effects as effective active ingredients of herbicides, and processes for preparing the same, and provides the compounds having a more efficient herbicidal activity, and efficient and industrial processes for the preparation thereof. More specifically, the tetrahydrophthalimide derivative obtained by reacting a halogen-substituted 5-cycloalkyloxyaniline derivative with a 3,4,5,6-tetrahydrophthalic anhydride, or the tetrahydroisophthalimide derivative of the present invention is reacted with various types of amines to prepare a tetrahydrophthalamide derivative represented by the general formula (I): ##STR1## These tetrahydrophthalamide derivatives and the tetrahydroisophthalimide derivatives exhibit excellent herbicidal activities in the soil treatment in the paddy field and field and the stem-foliar treatment. The tetrahydroisophthalimide derivatives are also useful as intermediates for the preparation of the tetrahydrophthalamide derivatives, etc.
