Title: Controller for synchronous motor
Inventor: YAMAMOTO HAJIME
IPC: H02P6/08
Filed: 1991-11-21
Abstract: PURPOSE:To obtain a current control system which operates stably even for abrupt variation of load except interference between dq axes in a controller for a synchronous motor wherein the synchronous motor is subjected to variable speed control through vector control. CONSTITUTION:The controller for synchronous motor comprises a first voltage operating unit 14 for operating an interference component due to leakage flux of dq axes based on d-axis current, q-axis current and speed and for compensating thus operated interference component, and a second voltage operating unit 15 for operating a value corresponding to an induced voltage based on an air gap d-axis flux, an air gap q-axis flux and a speed operated through a flux operating unit 6, wherein the first and second voltage operating units 14, 15 are arranged at the output stage of a current controller 8. A voltage command outputted from the current controller 8 is compensated by a value corresponding to an operated interference component to produce a new voltage command. Since the current controller 8 outputs only such voltage as corresponding to the variation of armature current and the voltage drop of armature winding resistance, output from the current controller 8 decreases and thereby stability is enhanced.

Title: Optical information recording medium
Inventor: ONO EIJI
IPC: G11B7/243
Filed: 1987-12-04
Abstract: PURPOSE:To decrease signals which remain without being erased by incorporating the fluoride of metals or semimetals into a thin recording film which exhibits a change in optical constant. CONSTITUTION:The thin recording film 3 is formed by adding the fluoride of the metals or semimetals to an optically active material which induces a phase change between amorphous and crystalline phases when irradiated with light or heat, etc. Namely, the fluoride of the metals or semimetals is not solutionized with the optically active material and, therefore, the formation of the macrograins of the crystals intruding among the fine crystals is prohibited while the optical characteristics of the thin recording film 3 are hardly impaired. The crystal state is thereby uniformized and the optical disk having the less signals remaining without being erased is obtd.
