IPC: H01J29/88
Filed: 1992-02-28
Abstract: PURPOSE:To provide a cathode ray tube capable of reducing an alternating electric field radiated forward passing through a face panel part from a deflecting yoke. CONSTITUTION:A conducting means 8, which conducts to a conductive film 6 and constitutes an electric field shield surface, is formed extending from a neck part 1a to a cone part 1b. An insulating means 9 for electrically insulating a deflecting yoke is formed on the conducting means 8. The conducting means 8 becomes an equipotential surface of zero volt by earthing the conducting means 8. An electric field shield surface is formed on a front region of the deflecting yoke, so that an alternating electric field, which is radiated to a front surface of a face panel part 2 passing through a funnel part 1 and the face panel part 2, can be reduced. A coil part of the deflecting yoke is electrically insulated from conducting means 8 by means of the insulating means 9 formed on the conducting means 8, so that no discharge or the like takes place. Electric field concentration is unlikely to take place since the conducting means 8 does not reach a neck seal line.

Title: Photographic lens
Inventor: SATO YASUHIRO
IPC: G02B13/18
Filed: 1988-02-29
Abstract: PURPOSE:To obtain the lens with excellent image forming performance by using as aspherical surface as at least one refracting surfaces which constitute an optical system. CONSTITUTION:Image forming operation is performed principally by a meniscus lens, but the aberration state that the lens system has varies greatly with the position of a stop placed on an image side as compared with the lens. Namely, when the lens and stop are close to each other, the power chromatic aberration decreases, but the astigmatism and lateral aberration deteriorate. When the lens is put away from the stop to the contrary, the lateral aberration and astigmatism are improved, but the power chromatic aberration increases. For the improvement of this state, at least one of the surfaces of the meniscus lens is made aspherical and the lens system is constituted. Consequently, the power chromatic aberration and astigmatism are compensated excellently and the excellent performance is obtained over a wide field angle range.
