Filed: 1987-04-24
Abstract: PURPOSE:To obtain an optical disk of stable composition whose production efficiency is high by making the refractive index of the surface layer of a transparent substrate on its side where a recording layer is to be formed higher than that of the substrate's body. CONSTITUTION:On the glass transparent substrate 12 of a magneto-optical disk 10, a recording layer 14 and a protection layer 16 and a reflecting layer 18 are laminated in this order. In the surface layer 20 on the side, the recording layer 14 is formed, a material such as boron or phosphorus that lifts the refractive index is diffused by such as thermal diffusion method to a certain depth, where the index is lifted up to approximately 2.0. When a straight polarized laser beam 22 is projected on this disk 10, a transparent reflecting beam 26 as well as a multiplex reflecting beam 24 is detected by an optical head, so exactly detect the rotation of the plane of polarization. Since the surface layer 20 functions as a multiple reflecting plane as the above, no dielectric interfering film needs to be formed, hence the production efficiency comes higher and a disk of a stable composition can be obtained.

Filed: 1984-05-22
Abstract: PURPOSE:To form a deposited film containing silicone atom at high filming speed while sustaining high quality at low energy level by means of utilizing heat energy at low level as exciting energy. CONSTITUTION:A cyclic halogenated silicate represented by a structural formula: SinXmYl [where X and Y respectively represent different halogen atoms while (n) represents integer of 3-6 also (m) and (l) respectively represent integer exceeding 1 while m+l=2n] and gaseous atmosphere of hydrogen are formed in a vessel containing a substrate while those compounds are supplied with heat energy to form a deposited film containing silicon on said substrate. The cyclic halogenated silicate represented by said structural formula is the halogen derivative of the cyclic hydrogenated silicate (cyclic silane compound) SinH2n, a highly stable compound to be produced easily. The (n) value is limited to the integer of 3-6, since the larger the (n) value, the easier the decomposition but the harder the evaporation and the synthesis while deteriorating the efficiency of decomposition.

Abstract: PURPOSE:To enable an amount of heat transportation to be properly adjusted and further enable the adjusted amount of transported heat to be kept constant by a method wherein an inner moving member is moved in a longitudinal direction of a hear pipe as a magnetic field of an outer guiding member is moved. CONSTITUTION:In case that the heat transporting capacity of a heat pipe 11 is improved, a pressing bolt 16 is loosened and an outer guiding member 15 is slid in a direction apart from an evaporating part A of a heat pipe 11. Since each of a permanent magnet 15a provided at this outer guiding member 15 and a permanent magnet 13a provided at an inner moving member 13 is retracted to each other by a magnetic force of each of the permanent magnets, the inner moving member 13 is moved in the same direction as the outer member 15 is moved. The outer guiding member 15 is fixed at a predetermined position by the pressing bolt 16, thereby fixing the inner moving member 13. As the inner moving member 13 is moved, an effective volume of a condensing part B defined within the heat pipe 11 is increased and a vapor pressure within it is decreased, so that an evaporation of the working liquid is activated and at the same time an effective thermal radiation area of the condensing part B is expanded and an amount of thermal radiation is increased, resulting in that a thermal transmitting amount by the heat pipe 11 is increased.
