Abstract: PURPOSE:To prevent carbon or the like in engine exhaust gas for driving a turbine from entering the rear surface side or bearing side of a turbine, by blowing out compressed air after the compressed air supports a shaft into a space proximate to the outer peripheral part of the rear surface of the turbine. CONSTITUTION:Compressed air fed from a compressor through an intake-air feed pipe 28 is jetted and fed into a gap between a journal bearing 22 and a shaft 21 and gaps between thrust bearings 34, 31 and an impeller 2 or a turbine 1 from a passage 27 through air feed holes 23, 35 and constrictions 25, 36.

Title: Post processing system for character recognition processing
Inventor: SUGAWARA HIDEAKI
IPC: G06K9/03
Filed: 1982-02-24
Abstract: PURPOSE:To keep a simple dictionary ready for use, by comparing an inputted character pattern with characters stored in the dictionary and registering this character pattern in the dictionary if it does not coincide with even the likest character and the inputted character is correct. CONSTITUTION:Character recognition is performed in a part 1, and the result is set to a register 2. For example, ''Kamiodanaka'' is defined as the first candidate, and ''Shimoodanaka'' is defined as the second candidate. First, ''kamiodanaka'' is set to a register 4, and the likest data ''shimoodanaka'' is set to a register 7 from a dictionary 5 for postprocessing by the indication of a matching circuit 6. A correction register circuit part 3 reads ''shimoodanaka''. Next, ''kamiodanaka'' is read from contents of the register 2 and is set to the register 4. The matching circuit part 6 extracts ''kamiodanaka'' as coincident characters and sets them to the register 7, and the correction register circuit part 3 reads this extraction. If ''kamiodanaka'' is not registered yet in the dictionary 5 for postprocessing, these characters are set to the register 4 and is inputted to the dictionary for postprocessing and is registered. Thus, additional registering is performed easily.

Title: Image-processing apparatus
Inventor: MORI NOBUO
IPC: B41J2/485
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent characters from being broken due to a size or a pixel density of characters when image data including characters are to be smoothed, by changing an intensity of a smoothing process in accordance with a character size of an image at a smoothing process part. SOLUTION: Without a smoothing process carried out, a pixel having a density level of an intermediate transfer body 26, 51, 77, 102 is added in (b)-(e). The density level of the pixel (pixel width) to be added to a step part 2 of an image 1 is changed in a plurality of levels, whereby an intensity of the smoothing process is gradually changed. In the case of the image 1 oblique right upward by 45 deg., the intensity of the smoothing process is increased gradually from (b) to (c) to (d) to (e), and therefore an oblique part is less jagged and becomes smooth. In this manner, characters are prevented from being broken due to a size thereof even when image data including characters are subjected to the smoothing process.

Title: Manufacture of silicon carbide semiconductor element
Inventor: UENO KATSUNORI
IPC: H01L21/265
Filed: 1994-02-28
Abstract: PURPOSE:To facilitate selective oxidation by forming an oxide film with thermal oxidation after implanting ions to the surface of a silicon carbide crystal. CONSTITUTION:Impurity ion 13 is implanted to silicon surface of a silicon carbide base material 11 utilizing photoresist as a mask 12. Next, after the mask 12 is removed, this silicon carbide substrate 11 is oxidized. Thereby, a thinner oxide film is formed on the area where ions are not implanted and a thick oxide film 15 is also formed in the ion-implanted area 14. When an oxide film or a silicon carbide film is used as the mask for ion implantation, it is not always required to be removed before oxidation. As explained above, when oxidation is carried out after ion implantation of impurity, a thick oxide film can be obtained, making possible easier selective oxidation and effective manufacture of silicon carbide semiconductor element.
