Title: Method and system for using single osd pixmap in multiple-video raster sizes by making osd header to ink
Inventor: ANEJA CHARU
IPC: H04N21/472
Filed: 2001-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a TV system which uses a single pixmap in a plurality of video rasters with different raster sizes. SOLUTION: At least two header sets (198 and 200) are used to select a different part to be displayed of a single pixmap (190) according to different raster sizes. More specifically, each header of a header set indicates a pixcel line, and selects the number of pixcels corresponding to the pixcel line. The number of headers in the header set determines a height of the pixmap, and the selection of the number of pixels by the header set determines the width of the pixmap. The TV system selectively calls ether of two header sets (198 and 200) and selects a different part in the single pixmap (190). Thus, the single pixmap can be used for a plurality of video rasters having different raster sizes.

Title: Optical signal amplifier
Inventor: SHIMIZU YUZO
IPC: H04B10/2507
Filed: 2001-05-24
Abstract: PROBLEM TO BE SOLVED: To reduce an unnecessary output voltage at an output which is generated because an unnecessary photocurrent flows to a photodetector for detecting signal light and is inputted to a differential amplifier circuit as a signal source. SOLUTION: A 2nd photodetector 11 is placed at a position not on the optical axis 2 of signal light, the 2nd photodetector 11 produces a photocurrent 12 such as a dark current and a photocurrent due to stray light 7 nearly equal in amount to that of an unnecessary photocurrent 4 from a 1st photodetector 3. The unnecessary photocurrent 4 from the 1st photodetector 3 and the unnecessary photocurrent 12 from the 2nd photodetector 11 are added while inverting the polarity of the currents to each other so as to cancel each other and the added current is given to and amplified by a differential amplifier circuit 5 as a signal source to be amplified. Thus, the unnecessary output voltage due to the unnecessary photocurrent 4 from the 1st photodetector 3 to detect the signal light can be canceled or reduced.

Title: Recorder, its method for detecting abnormality and its method for preventing fixing of cap
Inventor: NAITO HISATSUGU
IPC: B41J19/18
Filed: 2001-05-24
Abstract: PROBLEM TO BE SOLVED: To simplify a control necessary for judging an abnormality and also shorten the time therefor. SOLUTION: It is checked in a step S701 whether or not a cap is set. Nothing is carried out when the cap is not set. When the cap is set, a time when the cap is previously set and the present time are checked in steps S702 and S703. When a previous capping time is 0, it is so judged that a power supply is turned on for the first time, and a capping passed time is set to be equal to a threshold. When the previous capping time is not 0, the previous capping time is subtracted from the present time to obtain the capping passed time. A reciprocation operation is carried out only when the capping passed time is not smaller than the threshold.

Filed: 2001-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a distortion adjustment method for reducing distortions in the entire main field, even in a charged particle beam projection aligner in a separated transfer system having a large subfield. SOLUTION: Distortion in the transfer image of a subfield A' on an optical axis is measured for adjusting the excitation of a lens in the conventional excitation adjustment method of a projection lens. In addition to the conventional adjustment, a beam from a electron source 1 is flexed by an irradiation system deflector 2, so that the track of a is drawn for irradiating a reticle end, namely a subfield A at the end of a main field. Beam tracks b and c are apart from the center of projection lenses 4 to by a considerable amount, thus causing distortion in the subfield to be several hundreds times larger than an image transferred through conventional tracks b' and c' along the optical axis. The distortion which is magnified by several hundreds times is measured, and the current in projection lenses 4 to 7 is adjusted by a control power supply 11, so that the distortion becomes minimum.

IPC: B41J2/44
Filed: 2001-06-22
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a polygon mirror by suppressing the sticking of dust on the polygon mirror surfaces. SOLUTION: A polygon mirror reflecting surface partially has a dust collection area. In other words, the polygon mirror surface is provided with a rough surface area which increases the surface area of the mirror surface in a specific area on the surface.

Further, when the dust sticks on the polygon mirror surface, the dust begins to stick and be deposited gradually from an end surface part in the rotating direction of the polygon mirror.  For this problem, the sticking area for the dust is expanded by making large the surface area of the area from the end surface part in the mirror surface rotating direction to a use range, and consequently the time needed for the sticking body on the mirror surface to reach the polygon mirror surface use area becomes long, so that the life of the polygon mirror can be prolonged.
