Filed: 1988-09-27
Abstract: PURPOSE:To prevent an optical head from being floated by making a cross section of a rail regulating the optical head so as not to be moved in the same direction as the arranging direction of the sensors, in a recess shape. CONSTITUTION:A recessed part 3a is formed as shown in cross section in figure to a slide rail 3, which regulates the optical head 6 so as not to move it in the same direction as the direction of arrangement of sensors and the recessed part 3a is clipped by rolls 1, 2 whose outer circumferential face is formed to be projection. The center line of the projection of the rolls 1, 2 is more or less deviated upward fro the center line of the recessed part 3a of the slide rail 3. As a result, a downward force is exerted to the rolls 1, 2 pressed onto the rail 3 and the floating of the optical head 6 is prevented.

Filed: 1986-10-11
Abstract: PURPOSE:To eliminate the need for Fabri-Perot interferometer and absorbing cell for stabilizing stimulated laser by stabilizing a voltage controlled crystal oscillator VCXO and a stimulated laser wavelength based on the output of a photodetector. CONSTITUTION:A laser control circuit 12 controls a stimulating laser 2a by the output of a photodetector 5a and as the stimulated laser 2a, a CaAlAs semiconductor laser is recommended because of resonance wavelength, miniaturization and low cost. Moreover, the laser control circuit 12 applies the wavelength control of the laser 2a by injection current control. That is, the laser control circuit 12 detects a change from a frequency where the output of the photodetector 5a is maximized and a current corresponding thereto is fed to the laser 2a to control the laser 2a. Thus, the wavelength of the stimulated laser 2a is controlled so as to maximize the output of the photodetector 5a and the stimulating laser 2a is stabilized to make the device highly stable.

CONSTITUTION: Wedge-shaped bodies 1c and 1c are provided to tilt a transmitting probe 1a and receiving probe 1b to a subject 2 to be inspected by a desired angle. (p) represents an incident wave on the surface of a foreign matter (x), and (q) the reflected wave from the surface of the foreign matter. The phase in a section giving an angle at which reflection factor is 0 and a critical angle, is grasped beforehand by an experiment or a logic calculation to tilt the probes by such an angle as to give the reflection facor of 0 and the critical angle in the phase. As the angle and the critical angle at which the reflection factor is zero vary with materials composing the subject and foreign matter, the angles are known beforehand according to a specified object to be inspected and an ultrasonic wave is admitted at an angle within a range as expected.  The reflected wave thus obtained is used to judge whether the foreign matter (x) as cause of generating the reflected wave is a forecast specified foreign matter or not.
