Title: Deflection scanning device
Inventor: FUKITA TAKU
IPC: G02B26/10
Filed: 1994-11-29
Abstract: PURPOSE: To reduce thermal damage in an electric mounting part or the like of a rotating polygon mirror, bearing and a motor part, by directly fixing a sound/dust proof cap covering the rotating polygon mirror onto a magnetic laminated plate. CONSTITUTION: In a drive motor 2, a stator coil 10 and a magnetic laminated plate 11 constituting a stator are arranged in a position opposed to a drive magnet 9, and this magnetic laminated plate is directly fitted with a sound/dust proof cap covering a rotary polygon mirror 7. When the rotating polygon mirror 7 is rotated by the drive motor 2, a laser beam arranged in an optical box 1 is condensed by a lens group to perform deflection scanning toward a photosensitive unit; the cap 12 is provided with a laser beam incoming/outgoing opening part of window. By providing a constitution thus obtained, since a peripheral surface of the magnetic laminated plate 11 of the stator is exposed outside the cap 12, generated heat can be made to escape to the outside air directly through the magnetic laminated plate.  As the result, thermal damage to the rotating polygon mirror or the like can be reduced.

Title: Length measuring apparatus
Inventor: FUJIMOTO HIROHISA
IPC: G01B9/02
Filed: 1993-12-20
Abstract: PURPOSE:To make it possible to perform a highly accurate length measurement by providing a moving stage, which is moved into the measuring direction for a subject, and laser interferometers, which detect the moving amount of the stage and measure the lengths of a plurality of subjects that are arranged in symmetry with respect to the measuring points of the subjects. CONSTITUTION:The laser light from a laser light source 1 is split into two beams, and the beams are made incident on laser interferometers 3 and 5. The laser light beams emitted from the interferometers 3 and 5 agree with measuring points in the direction of the height. The laser beams are reflected from movable mirrors 6 and 7, which are mounted on a moving stage 10 in linear symmetry separated by an equal interval L1. The laser beams are made incident on the interferometers 3 and 5 again and then made to interfere with reference light. The moving amount of the stage 10 is detected by detectors 8 and 9. The stage 10 is driven along guide members 14a and 14b, which are arranged in parallel with an interval being provided in the measuring direction of a standard scale 13. Even if the stage is inclined into the yawing direction (arrow mark) and the moving distance is measured, Abbe's error can be eliminated by averaging two data because the moving distance is measured at the position in linear symmetry at the equal distance from the measuring points of the scale 13.

Title: High-frequency accelerator
Inventor: MISHIMA SHOJI
IPC: H05H7/02
Filed: 1992-11-30
Abstract: PURPOSE:To enable a klystron to continuously operate, even if an abnormality occurs in one high-frequency accelerating cavity, by using a bipolar selector power supply for feeding power to an electromagnet laid to apply magnetism to a circulator. CONSTITUTION:Power outputted from a klystron 1 is branched with a magic T2 and fed to high-frequency accelerating cavities 5. A beam is thereby accelerated. When reflection electric power is generated in the cavities 5 due to an abnormality, a reflection signal detected with directional couplers is sent to a circulator electromagnet power supply 7. This power supply 7 is a bipolar selector type and a circulator electromagnet 3b is deexcited, when the reflection signal is inputted. As a result, the power fed to the cavities 5 is outputted to dummy loads 4. When power is fed to a plurality of accelerating cavities in that way, the klystron 1 can be continuously operated without any power interruption, even if reflection electric power due to an abnormality such as vacuum and arc is generated in one cavity 5.
