Title: Contact
Inventor: HENRY O HERMAN JR
IPC: H01R13/66
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a spurious error in an electronic system by embedding a resistance material layer from the tip of the middle section of a slide contact face to form a nearly flat contact face, bringing it into contact with a mating contact section via the resistance material layer in the contact initial stage, and keeping it in direct contact with a conductive material at the complete contacting. SOLUTION: When the tip of a plug connector 6 is inserted into the cavity of a receptacle connector 8, a receptacle contact 15 is first brought into contact with the high-resistance section 12 of the tip section 11 of the plug contact 7. The energy from an electronic system starts to flow to the conduction section 14 of the plug contact 7 from the receptacle contact 15 via the high-resistance section 12. When the plug connector 6 is inserted further, the receptacle contact 15 is moved along a sliding contact face 16 until it reaches the conduction section 14 of the plug contact 7. When the plug connector 6 is inserted completely, it is brought into direct contact with the conduction section 14 of the receptacle contact 7, and no further voltage drop is generated on the high-resistance section 12.

Filed: 1978-06-02
Abstract: PURPOSE: To obtain a lens system featuring a reduced amount of the crossover and the aberration by adding the noses mainly at the 2nd grid and the electrode near the grid.  
     CONSTITUTION: A small-diameter cylindrical projection part, so-called the nose, containing the electrode hole is provided on the end bottom surface of electrodes G 2  excluding G 1  among the electrodes distributed among cathode K and electrode G 3  which is closest to the cathode among the electrodes forming the main lens. The protruded length l of the nose is set longer than diameter d of the cylindrical part. Thus, G 2  is separated into two parts belonging to different systems, that is, G 2 -1 part forming the cathode lens and G 2 -2 part forming the prefocus lens. As a result, a proper shape and size suited to each function can be obtained in a comparatively free way, realizing a prefocus lens featuring an extremely small aberration. And thus the state of the beam spot can be improved greatly. The aberration can be further reduced if the aperture of G 3  opposing to G 2  is formed cylindrical with its diameter D 3  set nearly identical to diameter D 2  of G 2  at the side of G 3 .
