    摘要： When evaluating defects, etc. of a sample by measuring thermal expansion displacement on the surface of the sample, which is produced by irradiating thereto an excitation beam of which intensity is cyclically modulated, a measuring beam having the displacement frequency F.sub.1 is irradiated to the vibrating surface of the sample, and the reflection beam is interfered with a reference beam having the frequency F.sub.2. The beat wave signal E.sub.1 (Beat frequency F.sub.b =F.sub.1 -F.sub.2) is converted to a binary signal E.sub.2. Then, the sample is evaluated by signals which are obtained by giving a suitable processing to the binary signals. In addition, the optic axes alignment is eliminated by utilizing the excitation beam itself concurrently as measuring beam.

    摘要： A digital information reproducing apparatus in accordance with a prior art that uses a semiconductor memory to realize a memory means cannot reproduce digital data which has been encoded according to a compression coding form different from the one adopted by an incorporated decoding circuit. According to the present invention, a decoding program stored in a second semiconductor memory is selected according to a compression coding form adopted for digital data stored in a first semiconductor memory. The selected decoding program is used to decode the digital data by means of an arithmetic circuit. Thus, digital information can be reproduced irrespective of a compression coding form adopted for provided digital information.

    摘要： The conventional speakerphone using the voice switch, when combined with the echo canceler, involves a problem that the threshold for switching the transmit/receive state of the voice switch cannot comply smoothly and stably with the performance variation of the echo canceler, thereby obstructing echo canceling in a manner that the voice switch cooperates with the echo canceler. The speakerphone of the invention estimates the performance variation of the adaptive filter by using the integrated value of a power of the receive signal or the transmit signal referred in the past when the adaptive filter learns, and varies the threshold in accordance with the performance variation. Thus, the speakerphone of the invention achieves a stable communication system that approaches to the fill duplex with the voice switching system and the echo canceling system combined.

    摘要： A surface inspection system detects imperfections on the surface of a hot radiant material, in which video signals for imperfections or defects are discriminated by comparison with normal level signals which are obtained through a variable area peak hold to preclude completely the influences of dark or bright defects which happen to be on the inspecting surface. The system includes apparatus for removing noises due to scales to produce outputs indicating true surface imperfections alone or indicating the degree of defectiveness of the detected defects. Also disclosed is a multi-camera surface inspection system capable of detecting defects on all sides of a hot radiant material which is transferred along a predetermined transfer line, with or without follow-up control of a camera or cameras scanning a given side of the material using edge signals detected from the normal level signal of another camera scanning a surface on the ensuing side of the material.
