摘要: A shadow mask is arranged to face a phosphor screen formed on an inner surface of a panel. A plurality of aperture columns are formed in parallel in the shadow mask. Each aperture column includes a plurality of apertures arranged in line at a predetermined interval. On both sides of each aperture column on the surface of the shadow mask facing the electron gun, stripe-shaped dielectric layers for acting on electron beams toward the apertures are formed respectively, and extend in substantial parallel with the aperture columns. The shadow mask is manufactured in such a manner that stripe-shaped insulating material layers are formed on the surface of a mask base material facing the electron gun, the mask base material is thereafter shaped into a predetermined shape, and the insulating material layers on the shaped mask are sintered.

摘要: An objective lens system, for example of a Gauss or Tessar type is provided having the capability of adequately correcting aberrations even when the lens system is focussed at a relatively close object. The lens system is adaptable for use in cameras and comprises a first lens group including an aperture stop and a second lens group positioned on the image side of the first lens group. The second lens group includes a first lens sub-group of positive refracting power and a second lens sub-group of negative refractive power. The air spaces provided between the first lens group and the first lens sub-group and also between the first lens sub-group and the second lens sub-group are varied to compensate for changes in aberrations resulting from focussing at a relatively close object. More specifically, the first air space is increased while the second air space is decreased when the object distance of the lens system is decreased.

The interchangeable lens comprises, inter alia, a code plate for producing a plurality of digital photographic distance signals representing given discrete photographic distances of the optical system in accordance with the adjustment of the optical system for focusing. Circuit means output a predetermined one of a plurality of inputs, the plurality of outputs including a plurality of conversion coefficients needed for converting the detected amount of defocus into the amount of drive to be effected by the driving means, the conversion coefficients being intrinsic to the interchangeable lens and having values depending upon the discrete photographic distances of the optical system represented by the digital photographic distance signals, respectively.The digital photographic distance signals are applied to the circuit means as the predetermined input to cause the circuit means to output one of the conversion coefficients as the predetermined output, the value of which depends upon the photographic distance of the optical system represented by the one digital photographic distance signal being produced. The output conversion coefficient are transmitted to the camera body.
