IPC: G11B20/18
Filed: 1991-12-24
Abstract: PURPOSE:To prevent a data from a disc which could not be corrected through a reproduced data error detecting/correcting process (uncorrectable data) from being recognized as a correct data and transmitted to a host unit. CONSTITUTION:A correcting circuit 9 performs error detection and correction for reproduced data in a sector buffer 2 based on syndrome result of the reproduced data added with a first error detection/correction code (Reed-Solomon code or the like). Thus processed data are then fed to an additional error detection circuit 7 where the first error detection/correction code is removed and a second detection code is added for each section. As the second error detection code, a regular parity is provided for errorless sector or corrected sector of the reproduced data whereas a value different from the regular parity (to be decided as an error) is intentionally provided for an uncorrectable sector. The value is detected through a circuit 10 and prevented from being transmitted to a host unit while at the same time the fact is notified.

Title: Apparatus for allowing insulating sample in analytical instrument to have nearly uniform surface potential
Inventor: LARSON PAUL E
IPC: G01N23/227
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To uniform a surface potential of an insulating sample by projecting electron beams of low energy to a sample area while a projection area outside a radiation area is kept in a negative charge stage and directing positive ions to the projection area near the radiation area. SOLUTION: X rays 6 illuminate a radiation area 12 of a sample 2, whereby photoelectrons are emitted. An electron gun 7 projects electrons of low energy to the sample 2, and a charged particle source 10 projects positive ions 11 of low energy of not larger than about 10eV to the sample 2. Both the electron gun 7 and the charged particle source 10 are controlled by a computer 13. The radiation area 12 is positively charged because of the emission of photoelectrons. A projection area 14 to which low energy electrons are projected is larger than the radiation area 12, including the radiation area 12, and therefore positive charges are neutralized. However, excessive negative charges are produced in an area outside the radiation area 12. For neutralizing the excessive negative charges, beams of positive ions 11 are projected to a part 16 of the area near the radiation area 12.  A surface potential of the sample 2 can be schematically uniformed according to the method.

IPC: G03G15/23
Filed: 1991-12-25
Abstract: PURPOSE:To shorten the length of time required for copying by immediately starting a copying operation when the number of documents is detected by the time a first document passes through an exposure area. CONSTITUTION:To carry out both-side copying it is necessary that the number of copies be informed in advance, therefore the recirculating document feeder which feeds documents D from a document container part 6 to the exposure area one at a time and returns the exposed documents D to the document container part 6 is used. However, when the number of documents is relatively small and when a document circulation sensor S6 detects the feeding of all the documents before the first document D1 passes through a reading position 5a, document recirculation for counting the number of the documents is stopped. Then, an reading exposure operation for the first document D1 in the reading position 5a is immediately started.
