Title: Automatic focusing device
Inventor: WATANABE TSUNEO
IPC: G02B7/28
Filed: 1989-06-22
Abstract: PURPOSE:To reduce the shock force when a moving member abuts on a mechanical limiting member by reducing the speed of a motor before the moving member abuts on mechanical limiting member even when a scan is made repeatedly in scan mode wherein focusing is disabled. CONSTITUTION:An arithmetic circuit converts data on the rotational quantity of a coupling 8a into the rotational quantity of the motor 6 and a set rotational quantity where the speed of the motor should be reduced at a specific position right before the projection part 3c of the moving member 3 for photographic distance adjustment abuts on an infinite-distance limiting member 4c or short- distance limiting member 4d is calculated from the rotational quantity. The moving member for photographic distance adjustment (distance operation ring) 3 is therefore reduced in speed right before the limitation of the infinite-distance, short-distance, or range limiter. Consequently, even when the driving speed of the distance operation ring 3 is increased so as to attain speedy automatic focusing, the speed is low at the time of a limit collision, so the shock force of the collision is reducible.

Abstract: PURPOSE:To improve electrostatic resistant quantity without enlarging the size of a pattern by forming a high-concentration doped P<+> type second region into a low-concentration doped P<-> type first region shaped to an N type substrate  and increasing the layer resistance of the first region and the second region by  one figure or higher. CONSTITUTION:The low-concentration doped P<-> type first region 12 is formed to the N type substrate 11, and the high-concentration doped P<+> type second region  is shaped into the region 12. A P<+> type third region 15 is formed to the outer circumferential section of the region 12, an N<+> type fourth region having high concentration is shaped while being contacted with the outer circumference of the region 15, and a P<+>-N<+> junction 17 is molded. Accordingly, resistance against electrostatic breakdown is increased because the layer resistance of the P<-> type first region 12 having low concentration is large, and the contact property of an electrode 19 is improved in the high-concentration doped second region 14.
