Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To avoid the generation of distortion and cracks of a neck part by preventing a contact of a conductive lead with an inner wall surface of the neck part when the conductive lead is expanded by high frequency heating. SOLUTION: At the time of high frequency heating to form a vaporized film 13 during the manufacturing process of a cathode-ray tube, a bimetal 14 is heated with a conductive lead 9. Then, an end of the bimetal 14, at which the bimetal 14 contacts the conductive lead 9, is bent in the direction for separating from a bead glass 8 by the property of the bimetal 14 and by fitting a part of the bimetal 14, of which coefficient of thermal expansion is lower then the other part of the bimetal 14, at a side close to the neck part 1. With this work, the lead 9 is stretched in the longitudinal direction, and even in the case where the lead 9 is expanded by heating, since the lead 9 is not drawn toward the inner wall surface of the neck part 1, the lead 9 does not contact the inner wall surface of the neck part 1. Consequently, generation of distortion and cracks in the neck part 1 due to a contact of the lead can be prevented.

Title: Magneto-optical field measuring equipment
Inventor: KANENOBU MUNEAKI
IPC: G01J4/04
Filed: 1992-12-02
Abstract: PURPOSE:To highly sensitively detect the intensity of a magnetic flux in a small area without being affected by electrical noise by spliting a light beam emitted from a magneto-optical element into two light beams in mutually crossing polarization directions to find a difference between the respective light- received outputs. CONSTITUTION:When a magneto-optical element 23 is scanned along the surface of a testee 5 and a magnetic field leaked from the defective portion 40 is guided into the element 23, the polarized condition of a light beam 2 is changed in proportion to a magnetic field H and injected to a polarizing beam splitter 24, so that, for example, a photoelectric current Ia in one photodiode 30 is increased and the output voltage IaXR of an operational amplifier 32 is also increased while a photoelectric current Ib in another photodiode 31 is decreased and the output voltage IbXR of an operational amplifier 33 is also decreased. So, if a difference V=(Ia-Ib)XR between the output voltages of the amplifiers 32, 33 is operated, voltage V approximately proportional to the magnetic field H can be obtained. In this way, corresponding component noise due to the output change of a light source 10 is offset and so the high-precision measurement of the intensity of the magnetic field H can be made.
