Abstract: PURPOSE:To provide a cathode-ray tube of high safety by forming a second conductive film in conduction to a conductive film formed on the surface of a funnel main body portion, and covering the horizontal deflection coil outer surface of a deflection yoke with an insulating member. CONSTITUTION:A second conductive film 9 is formed in conduction to a conductive film 7 formed on the surface of a funnel main body portion 1c in such a manner as to cover the outer surface of a funnel portion 1 from a cone portion 1b to a neck portion 1a. The horizontal deflection coil 8a of a deflection yoke 8 is covered at its outer surface with an insulating member. The film 9 is grounded via the film 7 and therefore serves as a conductive surface with a potential of 0V and a face having field shielding effects is formed in the opening front region of the yoke 8 whereby alternating electric fields produced at the yoke 8 and passing through the funnel portion 1 are reduced.

IPC: G01R31/30
Filed: 1990-05-15
Abstract: PURPOSE:To decrease a temperature decreasing time more less-expensively and more decreasingly by a method wherein every time a spacing reaches a predetermined temperature during a decreasing in temperature and a temperature decreasing gradient reaches a predetermined value, it is changed over to an expansion mechanism for decreasing temperature at a higher gradient than a predetermined gradient. CONSTITUTION:At the beginning of operation of a compressor 1, a valve 26 is turned on and opened, both capillary tubes 24 and 25 are applied. With such an arrangement, a spacing in a testing tank 12 is rapidly decreased along a temperature decreasing curve 1. As a temperature in the testing tank 12 is less than the first temperature T1 and a temperature decreasing gradient (a) reaches a point F reaching a value A, a valve 26 is turned off and closed and subsequently only the capillary tube 25 is used and the temperature is decreased down to a target temperature T0 along a temperature decreasing curve 2. In addition, irrespective of the fact that the temperature in the tank reaches the temperature T2, the temperature decreasing gradient (a) does not reach the value A, the valve 26 is closed at this time in order to make a positive prevention of liquid splashing into the compressor 11 and subsequently only the capillary tube 25 is used.
