Title: D-class amplifying circuit
Inventor: NAKAYAMA KAZUAKI
IPC: H03F3/217
Filed: 1982-10-22
Abstract: PURPOSE:To prevent the generation of distortions due to the interference of a side band wave to attain the negative feedback of a large quantity and to eliminate satisfactorily both carrier bands and noises, by separating a pulse modulator from a negative feedback summing point and at the same time inserting an LPF of a high order to a feedback line. CONSTITUTION:The audio signal applied to an input terminal IN is supplied to an analog amplifier 4 via an LPF10, and the output of the amplifier 4 is applied to a pulse width modulator 30-1 via an HPF20. The output of the modulator 30-1 is supplied to a power switching circuit 30-2, and the output of the circuit 30-2 is supplied to a load 3 via an LPF40. At the same time, the output of the circuit 30-2 is negatively fed back to the amplifier 4 via an LPF50 and a feedback circuit 5. Then a feedback loop formed by the LPF50 and the circuit 5 is separated from the LPF40 which eliminates carriers. The feedback quantity and the elimination factor of carrier band are set independently of each other. Then an HPF 20 which is smaller than the LPF40 by an order number is put into the feedback loop. This attains a large quantity of negative feedback.

On the other hand, the means PC is inputted with the video signal from the means IP and decides whether the correction of the width data of the joint part in each line is required or not in association of said data with the width data of the other lines. Said means decides whether the joint part is defective or non-defective in accordance with the respective width data determined according to the result of the decision. The inspection of the joint part is thus accomplished without contacting and with good accuracy.

Title: Method and apparatus for detecting inclination of measured object
Inventor: MARUYAMA TETSURO
IPC: G01B11/26
Filed: 1993-06-30
Abstract: PURPOSE:To make it possible to measure the inclination of a material to be measured in high accuracy with a simple constitution by providing a laser light source on a rotary plate, and operating the distance to a reflection point, where the reflected light from a target is received in correspondence with the change in position of the light source. CONSTITUTION:A rotary plate 14 is rotated by a motor and the like. A laser light source 16 provided on the plate is moved as a locus 32. When laser light Lf is outputted toward a target 12 from the light source 16, the laser light Lf is scattered on the target 12, and the reflected laser light Lr is received with a photodetector 18 at the center of the rotary plate 14. The distance to a reflecting point P is operated with a distance operating circuit 20 and stored in a memory 22. The line connecting the reflection points corresponding to the maximum value and the minimum value of the distance data is a major axis 28 of an elliptic light trace 24. A minor axis 26, which intersects the major axis 28 at a right angle, is the axis, which is orthogonal to the laser light Lf. Therefore, the inclination of a target 12 (material to be measured) with respect to the laser light Lf is computed with an inclination computing circuit 30 based on the position data of the major axis and the minor axis 26.
