Title: Ultrasonic flaw detection
Inventor: IWAMOTO KEIICHI
IPC: G01N29/06
Filed: 1983-02-24
Abstract: PURPOSE:To produce a highly accurate image of a flaw by converting a position coordinate in the circumferential direction as obtained in the flaw detection of a cylindrical object, during inspection of the inner surface thereof, into a true flaw position coordinate using a specified correction formula. CONSTITUTION:When the intersection between a working arm 14 and a probe mounting holder 15 is set at the point B, the position of a flaw 2 at the point F and the contact between a probe 16 and an object 3 to be inspected at the point S, as clearly shown from the coordinate system in the drawing, the Y coordinates of the probe 16 (the point B) and the defect 2 (the point F) are free from noncoincidence but the X coordinates of both do not coincide. On the other hand, if the relationship is determined between the points B and F when the X coordinate of the point B is X1 and that of the point F X2, it is given by the formula. X2 as the correct X coordinate of the flaw 2 is calculated by correcting X1 heretofore used as intact to obtain a correct defect image.

Filed: 1987-02-10
Abstract: PURPOSE:To prevent the damage of a laser reflection surface, and increase the data transfer speed, by arranging, between oscillation parts, a region whose resistance is made high by radiating high energy particles, and separating them electrically. CONSTITUTION:On an n-type substrate 1, the following are crystal-grown; an n-type AlxGa1-xAs clad layer 2, an AlyGa1-yAs active layer 3, a p-type AlzGa1-zAs block layer 4, and an n-type GaAs block layer 5. Then the layer 5 is subjected to a selective etching so as to reach the layer 4, and filled with the layer 4. In the active layer wherein the layer 5 is subjected to a selective etching, a current is constricted and injected. A part of mode vertically distributed from the active layer 3 reaches the block layer 5 in both end-regions, and suffers loss. Thus a laser oscillation part is constituted. The upper surface of the laser oscillation part is coated with Au, and irradiated selectively by proton beam. Thereby, a high resistance regions 6 deeper than the layer 3 is formed between the laser oscillation parts. Next, p-side electrodes 7 are formed separately in each oscillation part.

Title: A/d converter
Inventor: KANEAKI TETSUHIKO
IPC: H03M1/10
Filed: 1989-02-09
Abstract: PURPOSE:To make the A/D converter immune from the effect of surrounding noise by providing an A/D converter exclusively for a high input and a low input level respectively, amplifying the low input level, applying A/D conversion to improve the resolution and excluding an offset specific to the A/D converter digitally. CONSTITUTION:A specified analog input is inputted to an ADC 3 without any modification and an analog input amplified by 24dB at an amplifier 1 is given to an ADC 2. The ADCs 2, 3 converts a given analog signal into a digital signal and gives an output. Normally an A/D converter has its own specific offset level. Offset eliminating devices 4, 5 eliminate the offset and output a digital signal without any offset. Thus, A/D conversion is applied to an analog signal without any processing such as level switching and when the analog signal level is small, the level is amplified and then A/D-converted, then the resolution in increased and the effect of surrounding noise is hardly given.

Abstract: PURPOSE: To stably stop the oscillation part by flowing the driving current in the return direction only for a fixed time at the returning of said part and flowing braking current corresponding to the displacement speed thereof while detecting said speed thereby performing controlling.  
     CONSTITUTION: When exposure ends, the end signal Se is inputted to a control circuit 26 and the preset negative voltage is inputted to a servo amplifier 24 to flow return driving current to an arc motor 4. After lapse of a fixed time, the input to a servo amplifier 24 is cut off by the signal S 3  from a control circuit 26, at the same instant of which a brake control circuit 32 flows braking current to the arc motor 4 via servo amplifier 24 according to the displacement speed of an oscillating mirror 1. When the displacement speed of the oscillating mirror 1 becomes less than the specified value, no braking current is flowed. When the oscillating mirror 1 returns to the home position, an electromagnet 16 is energized by way of a control circuit 26, by which the mirror 1 is stopped. In this way, the rush speed of the oscillating mirror 1 into the home position becomes always less than the specified value and the mirror may be stopped stably.
