Title: Magneto-inductive measurement of diffusion film thickness - using compensated absolute eddy current probe to derive power density spectrum from which characteristic value representing power density variable is obtained  NoAbstract
Inventor: MOOK GERHARD DR SC TECHN
IPC: G01N27/82
Filed: 1990-12-21
Abstract: The magnetoinductive method of measuring the thickness of diffusion films involves the use of eddy current probes (W51, W52) and comparison bodies. A compensated absolute eddy current probe with depth characteristic matching the range of film thicknesses to be measured, is first subjected to broadband stimulation. The power density spectrum of the response signal is then computed and finally a characteristic value is derived from the spectrum. The characteristic value characterises the variance of the powder density in the frequency range of interest independently of the total power of the measurement signal and is correlated with the film thickness sought. USE/ADVANTAGE - Esp. for use in non-destructive quality testing of machinery. The method enables rapid diffusion film thickness measurement irrespective of the melt and processing charge.

Title: Optical recording and storage disc system - uses information from designated data control tracks to determine type of light recording medium and data format used
Inventor: TANAKA KUNIMARO
IPC: G11B7/004
Filed: 1991-04-26
Abstract: Data from the disc (1) control tracks is read by the optical head (17) and fed to a data translation unit (10) for demodulation and onto a medium decoding unit (11) which determines the type of light recording method used. If the disc medium utilises a direct light-modulated over write system a write processing unit (12) is activated to set the binary high/low light intensity switching levels required by the laser output control unit (14). In the event of a non-direct light-modulating system being detected a cancel/write processing unit (13) is activated which sets the high/low intensity levels required by the laser output control unit (14) for the clearing and recording of the disc data. The laser output control unit (14) is fed to a modulated binary recording signal via a Host-computer (19) and signal processing unit (15) which is used to control the light diode (18) intensity in accordance with the predetermined binary high/low levels. USE/ADVANTAGE - Recording system automatically adapts to direct light-modulation over write technique or other, dependent on disc control track data - accurate and error free recording process -data storage capacity of optical disc remains equal for different light recording techniques.
