Title: Objective lens driving device
Inventor: MARUTA KEIJI
IPC: G11B7/09
Filed: 1983-11-10
Abstract: PURPOSE:To make a device thin without damaging the sensitivity by providing a insertion hole, through which the tip part of a yoke arranged on the inside of an objective lens holding body is inserted in the approximate axial line direction of a supporting shaft, in the ojbective lens holding body. CONSTITUTION:An objective lens holding body 23 is provided with the insertion holes 31A and 31B in the axial line direction of a supporting shaft 22, and yokes 20d and 20e are inserted through these holes. Since a focus coil 35 and tracking coils 36A and 36B have not a double constitution on a circumferential side wall 23c of the holding body 23 and the movable weight of the holding body 23 is not increased, the sensitivity of focusing is not damaged. Further, since the outside diameter of the holding body 23 is not made large, the sensitivity of tracking is not damaged. On the contrary, the sensitivity is improved by the insertion holes of the holding body 23. Meanwhile, since the overall width of the circumferential side wall 23c of the holding body in the direction of the supporting shaft 22 is placed in magnetic gaps 37A and 37B between yokes 20d and 20e and yokes 27A and 27B by insertion holes and can be used effectively for the focus coil 35 and tracking coils 36A and 36B, the holding body 23 is made thin furthermore.

IPC: B41J2/205
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of image quality by performing multilevel halftoning of image data with regard to delivery of ink for each nozzle based on the correspondence between the pixels on a print medium and the nozzles and then forming dots corresponding to the results of multilevel halftoning on the print medium. SOLUTION: A CPU inputs an image data and print conditions specifying the correspondence between the pixels on a print medium and the nozzles for forming the dots thereof (S100). Resolution of the inputted image data is converted into resolution for printing through a printer (S105) and the converted image data is converted into a gray level data of each color being used by printer thus performing color correction (S110). Characteristics prestored with regard to ink delivery for each nozzle are reflected on the color corrected image data thus performing multilevel halftoning of the image data (S200). Dots of a printable data corresponding to the results of multilevel halftoning is outputted and transferred to a printer (S300, S310) where an image is printed out.

Title: Airtightness-leakage inspecting appartatus for tube fitting
Inventor: FUJINAMI MASAYUKI
IPC: G01M13/00
Filed: 1990-08-09
Abstract: PURPOSE:To improve detecting accuracy with less working man-hours by setting a tube fitting on a holding stage, and judging airtightness leakage by detecting differential pressure. CONSTITUTION:A plurailty of elbows M are conveyed to a holding stage 17 as one lot. Then, divided bodies 18A and 18B of the holding stage 17 hold each elbow M in the combined state. A cylinder device 20 lowers and drives a movable inspecting tool 21. Packings 22 and 23 are compressed to the elbow M. A compressor 28 feeds the air under the constant pressure into the elbow M. A measuring and judging part 30 measures the difference between the air pressure and the air pressure after a specified time has elapsed and judges whether airtightness leakage is present or not. The divided bodies 18A and 18B are separated with a driving control circuit 31 every time when the inspection of one lot is finished. A defective-product recovering shutter 33 which is provided at a good product chuter 32 is opened and closed based on the results of the inspections. The elbows M are dropped into a good-product route or into the detective-product route by their own weights. In this way, the airtightness leakage can be positively detected without visual inspection, and the working man- hours can be decreased.

Title: Disk reproducing device
Inventor: NAKAMICHI NIRO
IPC: G11B25/04
Filed: 1994-08-12
Abstract: PURPOSE:To prevent a disk from flawing by preventing the disk brought to the reproducing device and under the state of non-clamping from moving out of a disk placing part due to vibration by means of a clamper arranged close to the disk. CONSTITUTION:A carriage 17 is drawn out of a tray in a loading position after the tray is moved from an ejecting position to the loading position so that the disk 27 is moved to a reproducing position. In this reproducing device, the disk 27 is held in a placing recessed part formed in the carriage 17, but it may happen that the disk 27 is jumped out of the recessed part. In this case, since the clamper 50 is arranged close to the disk 27 at a shorter distance than the depth of the recessed part, the surface of the disk 27 to be jumped out is bumped against the lower surface of the clamper 50. Now, the clamper 50 in the non-clamping state is attracted by a magnet 52 to a magnetic plate 55 of an upper chassis 40, and hence the disk 27 is prevented from jumping out.
