IPC: H04N5/91
Filed: 1993-02-03
Abstract: PURPOSE: To record information on a recording medium with high efficiency by recording digital information in the continuation of an independently variable isolated mark and making the interval of the mark an independently variable length as well. CONSTITUTION: The beam of a writing laser 13 is focussed on the record rotating at a specified uniform speed via an intensity modulator 17 in accordance with a digitized modulating signal. A circular and cocentric recording track is formed in the recording medium 11. A glass substrate having a metallic layer coating the recording medium is included in the recording medium 11, and a recording layer pit is made when the intensity of the focussed beam exceeds a predetermined threshold. Since the intensity is modulated larger and smaller than the threshold value in accordance with a digital modulating signal to be recorded, an isolated pit i.e., the corresponding continuity of the mark is made in the record.  By this way, the space between the mark and mark is recorded in the recording medium 11 with high recording efficiency in a pulse width modulation form having an independently variable length expressing a continuous plural bit binary code block.

Filed: 1987-01-26
Abstract: PURPOSE:To realize baking at a high temperature by impregnating a coil formed of wound wire with an inorganic impregnant to form a ceramic insulation layer and covering the surface of insulated coil with inorganic glass layer in a vacuum. CONSTITUTION:The surface of insulated coil forming a ceramic insulation layer to a coil formed of wound wire is coated with inorganic glass material powder or a material which is vitrificated to inorganic glass by the baking. Next, it is baked at a temperature equal to or lower than the temperature where the material with which the surface of insulated coil is coated melts or vitrificates in a vacuum for sufficient degasification. Thereafter, it is then heated at a temperature equal to or higher than the temperature where the coated material melts or vitrificated. Thereby, the surface of insulated coil is covered with inorganic glass material. As a result, the amount of gas released from the inside of insulating layer and the amount of gas absorbed in the surface after it is placed again under the atmospheric condition can be reduced. As a material to form an inorganic glass deposition layer on the surface of insulated coil, a ceramic coating material obtained from the starting material of metal alkoxide can be used as well as glaze and glass powder.
