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 series-parallel A/D converter having a plurality of reference resistors, a first comparator section, a second comparator section, groups of switches, and lower-reference voltage lines. The reference resistors divide a full-scale voltage, generating different reference voltages. They are connected in series, forming blocks of resistors. The first comparator section compares an input voltage with upper reference voltages and selects one of the blocks of resistors in accordance with the result of comparison. The groups of switches applies the voltages at the nodes of the reference resistors of the selected block, to the lower-reference voltage lines. When the block BL0 is selected, voltages Vr0 and Vr8 are applied to the lower-reference voltage lines L0 and L8, respectively. When the block BL1 is selected, voltages Vr16 and Vr8 are applied to the lines L0 and L8, respectively. That is, the voltage applied through the line L8 remains unchanged, whichever block of resistors is selected.

Reference voltage generating circuit for use in series-parallel A/D

According to a high efficiency coding signal processing apparatus of the present invention, in order to suppress error propagation, effectively correct errors, and reduce a signal deterioration upon repetitive coding processing, a bit rate reduction circuit quantizes a video signal and outputs the resultant signal to low-and high-frequency encoders. A first transmission sequence packet circuit outputs low-frequency components at a predetermined period. A second transmission sequence packet circuit sequences and outputs high-frequency components. Since the low-frequency components and the high-frequency components are separately sequenced and transmitted, the low-frequency components are free from the influence of errors caused in the high-frequency components.
