Then, support plate 28 is provided at its fixed position with fitting part 31, via which support member 32 made of a nearly ring-shaped spring is also provided. To convergence electrode 27, getter support spring 34 provided at its middle with convex part 35 is cohered and the contact between this convex part 35 and the conductive coating of the funnel inner wall applies a high voltage to anode- voltage application voltage 26. Support member 32 is arranged nearly touching the neck inner wall and the voltage of the neck inner wall can be held at a desirable level by applying an adequate voltage via stem pin 29 from external power supply 36. As a result, color shading, a shift in color, etc., can be prevented without disturbing the electric field of the main electron lens.

Filed: 1989-03-20
Abstract: PURPOSE:To make the outer configuration of a device compact and to make workability excellent by providing a projection at the inner side wall part of a case so as to form a bottomless space. CONSTITUTION:A projection 101 is formed at the inner side wall part of a bottomless case 1 comprising a synthetic-resin side wall so that a bottomless chamber 12 can be formed. A gel-state filler 6 is injected into the case 1. At this time, the unfilled space 12 is formed in the projection 101 at the inside of the case. Therefore, pressure when the gel-state filler 6 is expanded can be alleviated. A part between lead terminals 5 in a semiconductor device is covered with the gel-state filler 6, resin 7 and the like. Therefore, the distance between the leads can be made smaller than the insulating distance in the gas. Thus, the compact and highly reliable semiconductor device characterized by excellent workability is obtained by a simple constitution wherein only the configuration of the side wall part of the case is changed.

Abstract: PURPOSE:To promptly and surely extract a contour line even when a scene is complicated or the ruggedness of an object surface is complicated by extracting a line segment and processing it while a boundary to partition the object from a background is being successively discriminated from a structure line to express the surface structure of the object. CONSTITUTION:By the operation of a comparator set in a contour extraction processing, attention points extracted as a part of the contour line are classified into boundary points and structure points. The respective classified frame points are allotted and stored into a special memory area consisting of a boundary line segment array memory 18 and a structure line segment array memory 19 which are completely separated. The line segment data arranged in the boundary line memory 18 and the structure line memory 19 are individually accessible in a main recognizing processing 21. Thus, since the positioning contrasted with the gradation density picture of the contour line on a data base is clear (the boundary and the structure), even at the time of the complicated analysis of the picture whose contour lines are enormous, a reliable processing result can be obtained.
