At least an effective region of the face of a panel of a cathode ray tube is held within a vacuum chamber. After the vacuum chamber is hermetically sealed from the outside of the vacuum chamber, a thin film is formed on the face of the panel by using a film-forming means.

Method of producing a cathode-ray tube and apparatus therefor

An apparatus for forming a panel surface film of a cathode ray tube is provided with a faceplate having an opening for supporting the cathode ray tube in such a manner that the panel surface of the cathode ray tube is exposed when inserted in the opening and is directed downward, a base member, a bearing, provided for the base member, for rotatably supporting the faceplate, and a torque transmission mechanism, coupled to a torque source, for transmitting torque of the torque source to the faceplate through the bearing. The bearing includes an outer ring having a circular inner shape, an inner ring rotatably fitted within the outer ring, rolling elements arranged between the outer ring and the inner ring, a coupling section which is formed on one of the outer and inner rings and to which the faceplate is coupled, and a fixing section which is formed on another one of the outer and inner rings and which is fixed to the base member.

Rotation transmission apparatus and apparatus for forming surface film of panel for cathode-ray tubes using the same

A method of exposing an object from both sides thereof, wherein the object has photosensitive material coated on both sides thereof and it is held between a first mask plate provided with a first masking pattern and a second mask plate provided with a second masking pattern. This exposing method comprises simultaneously image-sensing first and second alignment patterns formed at those areas on the inner sides of the first and second mask plates where the object is not held by the first and second mask plates so as to obtain an image signal, the first and second alignment patterns being in a predetermined positional relation when the first and second mask plates are correctly aligned with each other, processing the image signal to determine the positionally misregistered amount of the first and second alignment patterns from the predetermined positional relation, and moving one of the first and second mask plate in the facial direction thereof on the basis of the positionally misregistered amount of the alignment pattern thus determined to return the first and second alignment patterns to the predetermined positional relation.
