IPC: G03B27/62
Filed: 1989-11-30
Abstract: PURPOSE:To prevent the non-coincidence of sizes between an original and a copy by providing an original size detection means and a means for selecting one which is of larger size. CONSTITUTION:The original is set between a glass 4 and the transparent body 7 of a cover 6. The black part 9A of a moving member 9 stops in a state where it is opposed to the original 5 and an optical system 10 performs scanning. Outputted light is formed into an image on a CCD 12 and the image is processed, then the size detection means 14 detects the size of a white ground 9B surrounded by a black frame 2 as an original size, which is stored in a memory 15. Next, the white part 9B is opposed to the original and the black ground surrounded by a white frame 2' is detected. After detecting the size twice, a comparator 16 reads out and compares the size from the memory 15 so set the larger one as the original size. Then, by performing copying in a state where the white ground 9B is opposed to the original, only an image within the original size which is selected by the comparator 16 is copied on a paper. By such constitution, the accurate original size is obtained even in the originals provided with the black ground and the white frame and with the white ground and the black frame.

Title: Optical recording and reproducing device
Inventor: SASAKI YOSHIHIRO
IPC: G11B7/085
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To perform the stable full jump operation at the time of reproduction in the case the land/groove recording system is used. SOLUTION: The brake pulse time is set by a half track jump circuit so that the jump period at the time of half jump operation becomes equal to the kick pulse time (=Tk) at the time of full jump operation. Since the time when the kick pulse time at the full jump operation is finished, i.e., the changeover timing of the kick pulse and brake pulse is determined by the zerocross timing of a tracking error signal, a laser beam is positioned nearly at the center of the land in the zerocross timing. By setting so that the half jump operation is finished in the same period as the period from the start of jump operation to the zerocross timing, the moving locus of the laser beam at the time of half jump operation coincides with the moving locus of the laser beam at the time of full jump operation.

Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To cool sealing members and to prolong the life thereof by forming cooling water storage chambers for storing cooling water at the end faces of a roll and providing the cooling water storage chambers with routes to allow the advance of the cooling water concentrically with the sealing members. SOLUTION: A cast billet 2 of a high temp. is drawn while the roll 3 keeps rotating.

The cover parts 81 of the sealing covers 8 are formed with spaces between the axial ends of the roll 3 and the cover parts 81 to form the cooling water storage chambers 14. Hollow grooves 15 communicating with the cooling water storage chambers 14 are disposed near the outer periphery in the diametral direction of the seal rings 9. The cooling water passes the cooling water storage chambers 14 to cool the seal rings 9 and enters the cooling water courses 4, thereby cooling the roll 3. Since the seal rings 9 are cooled from inside, the life of the seal rings 9 increases and the life of bearings lasts long as well.
