Title: Detection for surface defect of steel plate
Inventor: KODAMA KENJI
IPC: G01N21/89
Filed: 1981-11-02
Abstract: PURPOSE:To permit erasing of harmless defects without degrading the flaw detection sensitivity for harmful surface defects by providing a photodetector which detects scattered light at the angle of photodetection at which the quantity of the light reflected from a specific defect and the quantity of the light reflected from a normal part coincide. CONSTITUTION:The laser light 12 irradiated from a laser light source 10 is scanned on the surface of a steel strip 4 in the transverse direction thereof by a scanner 16. The reflected light 18 which is reflected by the surface of the strip 14 and the scattered light 21 by a wet stain are detected respectively by a specular light detector 20 and a scattered light detector 22. The outputs of the detectors 20, 22 are compared in unit amplifiers 28, 30 so that the ratio between the noise level N preset by the voltage value for the differential waveform of the quantity of the light refected from a normal part and the voltage value S for the differential waveform of the detected signals is determined. The S/N value is compared with a set level in comparators 23, 34 and if any surface detect other than wet stains exists, a detection signal for harmful surface defects is outputted from an AND circuit 36.

Title: Flexible sound channel transmission system
Inventor: OTA SATORU
IPC: H04J3/16
Filed: 1989-07-11
Abstract: PURPOSE:To use a transmission line efficiently by switching encoder/decoders which differ in sound compressibility according to time zones and varying the number of sound channels automatically. CONSTITUTION:In a time zone wherein the use frequency of sound channels is low, a control signal for a pattern A which is outputted by a controller 2 is inputted to a sound compressing device 3 to perform switching to the pattern A, which is outputted to a transmission line 6. In a time zone where the use frequency of the sound channels is high, on the other hand, a control signal for a pattern B outputted from the controller 2 is inputted to the sound compressing device 4 to perform switching to a pattern B, which is outputted to the transmission line 6. Thus, the controller 2 can be switched automatically so as to output the preset patterns to the transmission line 6 in the preset time zones. The transmission line is therefore used efficiently and the change for line use can be saved.
