    摘要： Initialization nonuniformity due to interference of light which occurs during an initialization process is reduced without causing degradation in the characteristic of signals recorded/reproduced on/from respective recording layers. A multilayer optical disk comprising at least a first information recording layer and a second information recording layer formed, on a substrate, into a multilayer structure with an intermediate layer disposed therebetween is illuminated with initializing light from the side of the first information recording layer to initialize the first information recording layer formed of a phase-change material serving as a recording material. The illumination with the initializing light is performed such that the numerical aperture NA of an objective lens used for illumination with the illuminating light, the longitudinal length L of the beam size of the initializing light, the thickness D of the intermediate layer, and the ratio R1 of the amount of light striking the first information recording layer after passing through the first information recording layer and being reflected by the second information recording layer to the amount of light incident on the first information recording layer satisfy the following relation for a wavelength &lgr;i of the initializing light: L×R1 ≦25[1−exp(−0.0004×NA4×D2)].

    摘要： There is disclosed a sealing apparatus for picture tubes which includes a heater unit. This heater unit is located outside an index table, having bulb holders for retaining the glass bulb, during rotation of the table and is moved onto the table during a halt of the rotation. A bulb neck portion is encompassed with the heater unit to be heated by this unit. In this sealing apparatus for picture tubes, it is feasible to rapidly heat process the bulb neck portion without undergoing influences of external disturbances, whereby sealing of high quality can be obtained.

    摘要： There is disclosed a method of installing a mount assembly in a cathode ray tube wherein convergence characteristics are enhanced by properly setting levels of tube of a color cathode ray tube and of an electron gun. When a neck portion of the tube and a stem structure mounted with the electron gun are sealed to each other by heating, a distance between a standard level of the tube and that of the electron gun is measured. Comparison/arithmetic processing is effected both on the thus measured value and on a previously stored standard distance to seek a difference between the two values. The tube body or the electron gun is controlled by a moving operation so that the difference falls within an allowable value. After this, the sealing process is carried out.
