Title: Real-image finder
Inventor: ABE TETSUYA
IPC: G02B9/64
Filed: 1990-02-14
Abstract: PURPOSE:To reduce variation in the exit pupil diameter of even a zoom finder with a high power variation ratio by power variation and to prevent a flare from being generated at the periphery of the pupil by providing a stop at a position which is conjugate to the exit pupil in an objective optical system. CONSTITUTION:A zoom finder optical system consists of a 1st positive lens group L1, a 2nd negative lens group L2, a 3rd positive lens group L3, a lens prism P1, a composite lens prism P2, and a 4th positive lens group L4 in order from the object side, and an erect real image is observed through the 4th lens group L4. Then the stop 15 is arranged behind the 3rd lens group L3 at the position conjugate to the exit pupil 17. The exit pupil diameter can easily be adjusted by adjusting the diameter of the stop 15 and the flare at the periphery of the exit pupil can be reduce as much as possible. Consequently, a constant excellent image can be observed irrelevantly to the finder power and never deteriorates even if the pupil moves.

Abstract: PURPOSE:To suppress the short channel effect of a MOS transistor, by providing a conductor layer at side walls of a gate electrode; besides, by supplying electric potential to its conductor layer. CONSTITUTION:The source S or drain D of a MOS transistor is formed at n<+> type impurity diffusion regions 13 and 13a which are formed by implanting impurities of As<+> ion and the like and then, by treating with heat. A gate electrode G which is formed by a poly-Si film and the like is equipped on a gate oxide film. Further, sub-gate electrodes GS1 and GS2 which supply electric potential separately are formed on conductor layers 15a and 15b that are formed by the poly-Si film and so on at side walls of the gate electrode G. For example, the development of hot carrier due to electric field concentration is prevented by supplying electric potential of a sub-gate electrode GS2 of a conductor layer 15a at the drain side D in such a way that the foregoing potential becomes higher than that of a conductor layer 15b of the source side S and the resultant short channel effect is suppressed.
