IPC: H01J29/48
Filed: 1978-04-29
Abstract: PURPOSE: To decrease spherical aberration, by suitably selecting the electrode length and the electrode voltage, with the electrode constitution the same as the unipotential type electron lens.  
     CONSTITUTION: The electron lens is composed of three electrodes, and the same potential Eb is applied to the both electrodes 8, and Ef is applied to the intermediate electrode 9. In this case, the spherical aberration Cs is smaller by making longer the length Lf of the intermediate electrode 9, but it saturates at Lf/2R≥1.5. The longer Lf, the higher Ef, and it is recommended that the range of Lf is Lf/2R≤A -2  (Ef/Eb) 2  + 0.85, where; A =0.185. Further, when three electrodes are almost of the  same diameter, the electron lens having small spherical aberration can be constituted by this method.

Abstract: PURPOSE:To obtain a reliable stopper function with a relatively small-scale design change, by forming a projection shape part in a part of the stopper surface of an upper stopper attached to a container having a lid so that a lateral stopper arrangement is formed. CONSTITUTION:A projection shape part 15a of a suitable shape is formed in an upper stopper 15 at a suitable position above and in opposite to a lateral stopper 5c which is positioned substantially in the center of a cut-out part 7a in a frame 7. As a result, the stopper surfaces abutting against each others under shocks during transportation are limited to the stopper surface of the frame other than the cut-out part and the upper and lower stopper surfaces, which are the same as usual. The gap of a lateral stopper narrows by an amount corresponding to the height of the projection shape part 15a. In this case, the passing of the frame is eliminated by suitably selecting the height of the projection shape part.
