Abstract: PURPOSE:To match color balance with high accuracy and to obtain a picture with desired gradation by segmenting an original into plural regions and obtaining an average brightness in each region to obtain position information of the region where a maximum and a minimum value exist. CONSTITUTION:The picture signal of R, G, B colors is subjected to pre-scanning by applying scanning with a picture signal input section 10 in advance.

The picture signal stored at pre-scanning is inputted to a picture signal arithmetic section 16, in which the signal is segmented into rectangular regions with a prescribed size and the mean value Y of the brightness of each rectangular region is calculated from the input picture signal. The density of the regions whose mean value Y of the brightness is maximum and minimum is decided as a highlight point and a shadow point, and a table 12 is generated for respective R, G, B colors so that the highlight point is the gradation 255 and the shadow point is the gradation 0, for example. The table 12 is used to scan the original 8 and the gradation conversion is applied to respective R, G, B colors.

Title: Rotor for vacuum cleaner suction nozzle
Inventor: OHASHI HIDEO
IPC: A47L9/04
Filed: 1992-06-22
Abstract: PURPOSE:To provide a compact and rigid rotor which prevent thread dusts from being caught by forming a fin blade around the sleeve and by covering the rotor with the sleeve to integrate them. CONSTITUTION:When a rotor 2 is covered with a sleeve 16, a blade 4 is formed on the circumference of the rotor 2 so that the blade forms a fin radially projected from the rotor along the axial direction of the rotary axis 8 of the rotor 2. The sleeve 16 and blade 4 are formed as one part which is produced from a flexible material such as soft PVC, rubber, etc. As the rotor 2 is produced from a general material with high strength by extrusion molding, the rotor becomes light and vibration is reduced. As the blade 4 and sleeve 16 are integrated, the rotor 2 can be made thin, and the projection height of the blade 4 is larger, resulting that the flexibility of the blade is improved and the blade rotates smoothly. Additionally, as brushes can be implanted close to the blade, thread dusts, etc., are never caught by the brush and blade by their interaction.

Title: Production of polycrystalline silicon tft
Inventor: MISHIMA YASUYOSHI
IPC: H01L21/265
Filed: 1993-08-20
Abstract: PURPOSE:To improve a leading property of a polycrystalline silicon TFT and reduce OFF-state current by hydrogenating a polycrystalline silicon film prior to forming an interlayer insulation film, etc., and introducing not only hydrogen but conductive impurities being different from those in a channel area at the same time. CONSTITUTION:Hydrogen ions and B ions 13 which are impurities determining the conductivity type are simultaneously introduced from the outside to a polycrystalline silicon film 12 formed on a glass substrate 11 by using an ion doping method (ion shower method) or plasma doping method. As a result, an originally weak n-type polycrystalline silicon film 12 is changed into a high- resistance i-type and its uncoupled bonds are compensated, so that it can be inactivated electrically. Therefore, the property of the polycrystalline silicon TFT can be improved without adding complicated processes newly and changing its construction and its rising property can be also improved, resulting in reducing the OFF-state current.
