Title: Optical pickup
Inventor: SUGIURA SATOSHI

Filed: 1989-08-04
Abstract: PURPOSE:To form an optical spot in an optimum state by interposing in a photowaveguide pass a light quantity distribution converter having the characteristic attenuating the light quantity distribution in the transverse direction of the photowaveguide pass larger than that at the end part side in the transverse direction thereof. CONSTITUTION:The light poured from a semiconductor laser 5 is directed for a converging grating coupler 4 via a light waveguide pass 6 but it becomes a uniform light quantity distribution at an a point located before a light quantity distribution converter 13. Then it becomes in the light quantity distribution of an almost mountain like at the point b of after its passing under the con verter 13. As a result the light thus distributed is converged by a converging grating coupler 4 to form a spot 10 and a zone 12a becomes of the good one of less light quantity. The zone 12a thus reduced by the converter 13 is of the body located on an x axial direction and not reduced in respect of a y axial direction. The generation of a crosstalk thus is prevented because of the zone 12 mounted on an adjacent track being reduced in the case of the extension direction of the light waveguide pass 6 of the converter 13 being run along the y axis and made parallel to the direction of the track.

Filed: 1986-08-28
Abstract: PURPOSE:To make a real-time display on the display screen of a large-screen liquid crystal display device by transferring data from a digitizer to a frame memory right after its input. CONSTITUTION:When image data is displayed on the large-screen display device, an input from the digitizer is monitored (21) after initial setting (20). When the data is inputted from the digitizer, a digitizer control part calculates (22) its X and Y coordinates. A process flow extraction program 23 determines a jump destination among a display partial erasing process 24, a display erasing process 25, an all-data transfer process 26, and a one-data transfer process 27. The one-data transfer process 27 transfers the image data to the frame memory right after the data is inputted from the digitizer. Consequently, the input data from the digitizer is displayed on the large-screen liquid crystal device in a real time.
