摘要： PURPOSE:To enable eccentricity tracing of a pipe by removing effect on a beveled surface at the end of the pipe, by installing photoelectric element for beveled surface position detection, controlling circuit means, and gate circuit means. CONSTITUTION:An output signal 22 of an amplifier 21 from the time of receiving irradiating laser beam by a beveled surface position detecting photoelectric element 20 up to suspension of the beam is compared with the specified value V1 by a comparator 23. While the signal 22 exceeds the specified value V1, an output signal 24 of the comparator 23 assumes a change of condition from L to H. And, the instant when the output signal 24 changed from H to L is detected by using a reflected beam of light which scanned running over an end of a pipe. Further, while the irradiating laser beam scans the beveled surface, controlling signals 15, 17 are stopped by controlling signal gate circuits 27, 29. By this, a faulty action of the controlling circuit due to abnormal reflection at the time when the beveled surface of the pipe is scanned can be prevented.

摘要： PURPOSE:To enable measurement of body shape with the constant accuracy over the whole measuring range, by changing amplifier gain in proportion to intensity of the reflected beam of light obtained from a surface of a specimen. CONSTITUTION:An output current from a position sensitive detector (PSD) element 8, when for example, constructing 2 different kinds of amplifiers, is subjected to voltage conversion by amplifiers 19a, 19b, 20a, 20b and further, amplified by a gain set by each amplifier and introduced into signal selecting circuits 21a, 21b as inputs. The circuits 21a, 21b, after switching 2 input signals per each scanning period, issue output. These signals are calculated by subtractor 11, adder 12 and divider 13. Next, an identifying circuit 24 identifies only a signal of the preset level as an effective signal, feeding out a gate signal to a gate circuit 25. The circuit 25 issues out the division result only in the range identified as effective. Thus, measurement becomes available covering all the range of the 2 specimens of the specimen.

摘要： PURPOSE:To reduce memory capacity to only necessary data capacity by confirming the effectiveness of data at the output stage of a photoelectric element and outputting only effective data to a computer. CONSTITUTION:Current signals IX1 and IX2 are voltage-converted and amplified by amplifiers 7 and 8 and then inputted to a subtracter 9 and an adder 10 at the same time, and their outputs are inputted to a divider 11 to perform position arithmetic. Position information obtained as the output of the divider 11 is inputted as the X coordinate of a light point to the computer. At this time, the output of the adder 10 is constant when the light point is on a PSD (position sensing device) and 0 when the light point disappears from on the PSD. For the purpose, the output of the adder 10 is supplied to a binarization circuit 14 to detect whether there is the light point on the PSD or not. Further, a gate circuit 13 which receives the output of the circuit 14 as a control input and the output of an A/D converter 12 as a signal input is provided to inhibit data from being expelled when there is no light point on the PSD.

摘要： PROBLEM TO BE SOLVED: To reduce deterioration of pulse width and to attain proper optical communication by providing a constitution, where a differential input/output type differential amplifier means converts a current signal into a voltage signal, a generator means generates a midpoint potential between the positive and negative phase outputs of the differential amplifier means, and a 1st feedback load means is placed between the output terminal of the generator means and the negative phase input terminal of the differential amplifier means. SOLUTION: A differential amplifier 2 outputs positive and negative phase outputs, in response to an input signal. A midpoint potential generating circuit 4 inputs the positive and negative phase outputs and generates a midpoint potential between these phase outputs. A feedback resistance 5 feeds the midpoint potential back to the negative phase input terminal of the amplifier 2. Then the threshold voltage of the midpoint potential becomes equal to 0 level of the input signal to attain an operation that uses the linear region of the amplifier 2 to its maximum. As a result, the distortion of output duty is reduced despite the presence of a large input signal near the largest light receiving power.

摘要： PURPOSE:To detect the change of position of reflected light from the surface of a screw surely by irradiating light on the surface of a screw, receiving reflected light by a main photo-electric element and photo-electric elements for tracking arranged on both sides and making surface inspection controlling unbalance of output signals of the photo-electric elements for tracking within a specified value. CONSTITUTION:In a controlling circuit device, specified values +DELTAV, -DELTAV are set for output signals 13 by comparators 14, 16 and controlling signals 15, 17 are generated when output signals 13 exceed the values. It is possible to judge to which side reflected laser beam 5 is deviated from the center of the main photo-electric element depending on which one out of controlling signals 15, 17 comes out. Accordingly, the direction of moving of an actuator (not shown in the figure) that moves the main photo-electric element 2 and photo-electric elements 2A, 2B is determined by controlling signals 15, 17. Reflected light utilized by photo-electric elements 2A, 2B is feeble light 5A which is not utilized by the main photo-electric element 2, and does not give influences on essential signals for the surface inspection.

摘要： PURPOSE:To inspect the surface of a screw and to discriminate simply the position of a tube end by projecting and scanning luminous flux in the axial direction with respect to the tube on the end of which the screw is processed and catching reflected light from a screw part. CONSTITUTION:The titled instrument is provided with a follow-up mechanism to make a photodetector follow up a directional change of the reflected light from the screw part, a tube end photodetector 16 to photodetect rays of light deviated from the tube end and a signal processor. Then, a photodetection part is followed up with the follow-up mechanism to that the photodetection part catches the reflected light under a prescribed condition based on the output electrical signals from plural photodetectors 14l and 14r for follow-up provided at both sides of the photodetection part. Further, the luminous flux projected on the position exceeding the tube end is photodetected with the photodetector 16. Then, the reflected light from the screw part is caught with the photodetection part and the electrical signal which is converted photoelectrically from the light is subjected to binarization processing with a waveform shaper 21 and a pulse train obtained as the output of the shaper 21 is received to measure the pulse width with time width measuring instruments 24 and 25. The existence or nonexistence of a defect of the screw surface is decided based on the pulse width. Further, the output of the photodetector 16 is inputted to a deciding device 26 and used for deciding the existence or nonexistence of the defect of the screw surface.

摘要： PURPOSE:To enable the inspection of a surface flaw without lowering detection accuracy, by receiving light by following reflected light by an apparatus for rotating and transferring a material to be inspected even if the light irradiation position on the surface of the material to be inspected changes. CONSTITUTION:When reflected light changes to the lower side in a circumferential direction, the light receiving quantity of a lower side light receiving part 3c is reduced and that of an upper side light receiving part 3b becomes much. Light receiving parts 3b, 3c respectively output electric signals with levels corresponding to the respective light receiving quantities to sample hold circuits 6, 7 and, when the circuits 6, 7 input the hold order signal from a light scanner controller 5, said circuits 6, 7 hold the respective output signals of the light receiving parts 3b, 3c and output the same to a differential amplifier 8 until the next hold order signal is inputted. The amplifier 8 amplifies a difference signal portion to a servo amplifier 13 which, in turn, rotates a servo motor 9 on the basis of the input signal and the light receiver 3 is downwardly revolved through a guide rail 11 to allow reflected light to enter the light receiving parts 3b, 3c in the same quantity. By this method, the lowering in detection accuracy an be prevented.
