IPC: G03G15/01
Filed: 1986-01-31
Abstract: PURPOSE:To attain color correction improved at gradation reproducibility by irradiating an erasing pattern simultaneously or immediately before or after an exposure process to a photosensitive body and changing an erasing rate or the erasing pattern in accordance with a decomposed color. CONSTITUTION:A charger 12, an eraser 18 and developing devices 20, 22, 24, 26 are arranged on the periphery of the photosensitive body 10 and a color original '0' to be copied is set up on an original setting glass 16. A filter device F is formed on an exposure optical system 14 for projecting an original image to the photosensitive body 10. Plural erasing rates or erasing patterns corresponding to previously decomposed colors are stored in a memory 54 and one of them is read out by the selection of a selection key or a photoelectric transducing output from a CCD 51 receiving the reflected optical image from the original. Thus, the eraser 18 executes erasing by changing the erasing rate or the erasing pattern in accordance with the decomposed color. Consequently, color correction improved at gradation reproducibility can be attained.

Title: Optical disk retrieving method
Inventor: NAKATSUJI FUMIO
IPC: G11B21/08
Filed: 1987-01-31
Abstract: PURPOSE:To attain high speed access by detecting the actual linear velocity of a disk, storing the speed and correcting and retrieving the track number read from an address table corresponding to the actual line velocity. CONSTITUTION:The actual line velocity of a disk 2 is detected by a linear velocity detection circuit 13 and the actual linear velocity of the disk to be detected is stored in the linear velocity memory 14. A track number from the start point of the disk inner circumference with respect to each address calculated by the designated linear velocity is stored in the address table 15. A CPU 7 corrects track numbers X1, X2 read from the disk 15 based on the ratio of the actual linear velocity and designation linear velocity, obtains the track number to be jumped from corrected track numbers X1', X2' to retrieve the object address. Thus, the jumping track number is always accurate independently of the difference of the linear velocity of each disk, which is used for the optical pickup feed control at random access to attain high speed random access.

The assembly is then subjected successively to coating of a flux, immersing in a solder tank, cooling, removing of the chip carrier and washing. The immersion is accomplished for the time when gold is substantially subtd., i.e., for about 4sec or longer in this stage. The concn. of gold in the cell is controlled to about <=0.2% to maintain the concn. of the gold of the pad 7 at about 0.2-0.5%. The need for the stage of coating the resist for soldering is thus eliminated, by which the man-hour schedule is reduced and the unevenness in the soldering is eliminated.
