Abstract: An optical scanning device includes a plurality of light sources, a light deflector, and a single scan lens. The light deflector deflects a plurality of light beams emitted from the light sources by a same face for scanning a plurality of to-be-scanned portions simultaneously. The single scan lens receives the light beams from the light deflector and focuses the light beams onto each of the plurality of to-be-scanned portions to scan the to-be-scanned portions simultaneously. The single scan lens is used in common for the light beams, and has one incidence plane and a plurality of exit planes in a sub-scanning direction separately prepared in the sub-scanning direction for each of the to-be-scanned portions. The incidence plane has a refractive power of the lens in the sub-scanning direction decreasing toward peripheral portions in the main scanning direction. The exit planes have positive refractive power in the main and sub-scanning directions.

Abstract: The data processor of the present invention can play back video and audio synchronously from an optical disk, on which video and audio data are stored in different areas. Each area consists of one or more unit areas. The data processor includes: a playback control section for giving instructions on how to read the video and audio data and how to play back the video and audio based on the read data; a head for reading the data from one of the unit areas after another in accordance with the instructions; and audio and video buffers for retaining the audio and video data read. The playback control section instructs that the audio data be read from a predetermined one of the unit areas to the audio buffer memory, and then instructs that the video data, which is to be played back over first and second periods of time, be read from a number n (where n is an integer equal to or greater than two) of unit areas to the video buffer.

In advance, a hydrophobicized powder is dispersed in an oil phase and processed with wet type disperser such as beads mill, dispersing solution is obtained. And then said dispersing solution and a water phase are processed with homomixer, an oil-in water emulsion composition having excellent sense of use and dispersibility of powder after applying to skin can be obtained. The dispersing stability of powder is extremely good by using a particular dispersant and a particular oil component. The dispersion stability of powder is further improved, and the precipitation and creaming of the emulsion particle can be solved by blending thickener having salt tolerance. Sticky feeling is solved by using succinoglycan as a thickener, and twisting is solved by plasticizing said succinoglycan.

Abstract: Ribs for defining pixel cells are formed in the shape of a lattice, and sustain electrodes and scan electrodes are disposed near the ribs. The electrodes are spaced apart in each pixel cell, and the sustain electrode and the scan electrode are each cut away between pixel cells arranged in the row direction to provide each pixel cell with individually separated electrodes. In addition, between pixel cells adjacent to each other in the row direction, the sustain electrodes and the scan electrodes are connected to each other by means of a sustain-side bus electrode and a scan-side bus electrode, respectively. This makes it possible to provide a high luminous efficiency. Furthermore, each pixel cell is provided with a wide distance between the electrodes and thereby with a large effective opening portion. Thus, this provides only a small amount of reduction in intensity when the electrodes are spaced apart between the pixel cells arranged in the row direction in order to increase the luminous efficiency.
