Abstract: The present invention provides a resin composition comprising 100 parts by weight of a methyl methacrylate resin or styrene resin, about 0.1 to about 20 parts by weight of a light diffusing agent, about 0.0005 to about 0.1 parts by weight of an ultraviolet absorber selected from the group consisting of 2-(1-arylalkylidene) malonates and oxalanilides, and about 0.0001 to about 0.01 parts by weight of a phosphor. This resin composition is used as a material of a light diffusing member showing excellent light diffusible transmittance, having excellent durability and manifesting suppressed yellowing of transmitted light. Further, a laminated plate obtained using this resin composition is suitably used as a lighting cover, light diffusing plate for liquid crystal displays, illumination sign board or the like for which light transmittance and light diffusing property are required and durability is desired.

Abstract: A steering locking device has an annular clearance provided between a steering shaft and a collar surrounding the steering shaft. A spacer is press-fitted in the annular clearance, to form a circular arc shape surrounding the steering shaft. The spacer is wound around the steering shaft from the outside of the collar through the opening of the collar. When a locking member supported on a locking device main body is at a locked position, the collar is prevented from being rotated. When a torque applied to the steering shaft is not more than a predetermined torque, the spacer prevents the relative rotation between the steering shaft and the collar.

The article is excellent in curbing the coloring in melt processing.

Abstract: In a picture reading apparatus, in the pre-scan, an approach is employed to control a CCD line sensor 5 and a film carrying roller 103 so that plural pictures recorded on an optical film 1 are read at a predetermined sampling rate in order from the latest frame to generate frame position data indicating position of left and right ends of frame, etc. Further, in the main scan, an approach is employed such that, in controlling the CCD line sensor 5 and a film carrier 100 so that plural pictures recorded on the optical film are read at a sampling rate higher than the predetermined sampling rate in order from the oldest frame, the reading start and end timings of the CCD line sensor 5 are controlled on the basis of frame position data obtained by the pre-scan. As a result, in this picture reading apparatus, it is possible to precisely obtain picture data of picture of frame in the state where no positional shift takes place.

Abstract: A color video printer can identify the length of a print sheet inserted therein for ejecting any print sheets other than a standard print sheet. The printer has a sheet feed sensor and another sensor disposed downstream of the sheet feed sensor with respect to the direction in which a print sheet is fed in the printer. After the leading end of an inserted print sheet is detected by the sheet feed sensor, the print sheet is fed until the leading end thereof is detected by the other downstream sensor. At this time, the length of the print sheet which is fed is equal to the distance, typically of 128 mm, between the sensors. The true length of the print sheet is calculated by adding, to 128 mm, the length of the print sheet which is further fed until the trailing end of the print sheet is detected by the sheet feed sensor.
