Abstract: A self-luminous apparatus is disclosed wherein a deterioration amount difference between different pixels can be eliminated accurately to correct a sticking phenomenon while the self-luminous apparatus is used. In the self-luminous apparatus, a deterioration amount difference appearing between a correction object pixel and a reference pixel within a first light emission period of time is calculated first using a deterioration ratio derived from gradation values of the pixels. Then, a deterioration ratio for correction for the correction object pixel necessary to eliminate the calculated deterioration amount difference within a second light emission period of time is derived using a deterioration ratio of the reference pixel. Thereafter, the derived deterioration ratio for correction is converted into a corresponding gradation value, and the correction object pixel is driven to emit light with the converted gradation value.

The pulley comprises a pulley main body (10) and flat members (20) fixed thereto, the flat members (20) having screw holes (20c) formed therein.

Namely, a weight reduction can be attained by thinning the projecting part (12) and a reduction in production cost can be attained by the weight reduction.

Abstract: A telescopic shaft for steering of a vehicle is assembled in a steering shaft and includes a male shaft and a female shaft that are so fitted as not to be rotatable but to be slidable. Rolling members are fitted through an elastic body for pre-load between at least a pair of axially-extending grooves formed in an outer peripheral surface of the male shaft and in an inner peripheral surface of the female shaft. A slide member is fitted in between at least another pair of axially-extending grooves formed in the outer peripheral surface of the male shaft and in the inner peripheral surface of the female shaft. When a steering toque is equal to or smaller than a predetermined level, the elastic body for the pre-load exhibits a low rigidity characteristic as the elastic body performs pre-load action. When the steering torque is equal to or larger than the predetermined level, the slide member exhibits a high rigidity characteristic as the slide member engages with the pair of axially extending grooves.
