Title: Shadow mask type color picture tube
Inventor: HATTORI MUTSUMI
IPC: H01J29/07
Filed: 1988-02-08
Abstract: PURPOSE:To reduce the color purity drift in the early stage of the operation of a picture tube even at a low temperature by making the thermal expansion coefficient of the frame to fix a shadow mask 20-80% smaller than that of the shadow mask. CONSTITUTION:On the surface of the electron gun side of a shadow mask 7 provided with a large number of apertures heavy metals such as bismuth, tungsten, lead or the like are coated as the reflection layer for electron beam, and the periphery of the mask is folded to form a mask skirt for attaching to a frame 9. On the frame 9 holding the shadow mask 7 springs 11 are provided, and the shadow mask assembly 5 is attached to pins 4 with the spring 11. The frame 9 is made of a material the thermal expansion coefficient of which is 20-80% smaller than that of the base material of the shadow mask. Thereby the deformation of the shadow mask due to the variation of the ambient temperature can be suppressed, and the color purity drift especially in the early stage of the operation at a low temperature can be effectively reduced.

Abstract: PURPOSE:To continuously make plural copies of a long-sized original from the original set only once, by reversely driving a driving means to move an original backward when the number of copies is smaller than a set number and after an original detector detects the rear end of the advancing original, and then, normally driving said means to move it forward after the detector detects its front end. CONSTITUTION:When a servomotor 25 rotates normally, an original 9 is moved forward with a forward carrying roller 21, and when an original detector 27 detects the rear end of the original 9, a cutter 18 cuts transfer paper 16. When a counted value is less than a set number to be copied repeatedly, the result is sent to a motor control circuit 31, the motor 25 begins to reversely rotate to move back the original 9 after the rear end of the original 9 reaches the position for exposure. When the detector 27 detects its front end, the motor 25 stops and begins to normally rotate again. Such operations are repeated and when the counted value of an addition counter 40 coincides with the set number to be copied repeatedly, the motor 25 continues normal rotation without stop, and the original 9 is stocked in an original receiver 13 or 14. As a result, plural copies can be made only by setting an original.
