Title: Magnetic flux leakage flow detector
Inventor: HAMADA SHOICHI
IPC: G01N27/83
Filed: 1991-09-03
Abstract: PURPOSE:To improve the S/N of a detector and constitute the detector to have an easily adjustable simple structure by detecting the phases of the output signals of two or more differential circuits respectively composed of pairs of adjacent detection coils in such a way that one of the phases is detected through a phase shifter and the other phase is directly detected. CONSTITUTION:A material 1 to be inspected is run through detection coils L1-L3 coaxially arranged in series in parallel to the direction of a magnetic field. In-phase amplifiers 11 and 12 and inverting amplifiers 13 and 14 respectively amplify the outputs of the coils L1,3 and L2 and adder circuits 15 and 16 input the amplified outputs. The circuit 15 and 16 respectively form differential amplifiers (a) and (b) and output A and B. An output G obtained by shifting (g) the phase of the output A and the output B are inputted to a phase detector (d) and the outputs A and B are inputted as they are to another phase detector (c). The outputs C and D of the detectors (c) and (D) are outputted as outputs E and F after addition (e) and subtraction (f). At the time of outputting the outputs E and F, the S/N can be remarkably improved when the noise contained in the output F is minimized by adjusting the phase shifter (g) so that the output E can become the maximum.

Abstract: PURPOSE:To take an arbitrary wafer in and out without a pair of tweezers by a method wherein a drawer and holding lever for wafers in a wafer carrier is integrally built-in on a flat transfer substrate detachably inserted to the wafer carrier in a free manner. CONSTITUTION:To remove the wafer 3 from the wafer carrier, the knob 7a of the holding lever 7 is pulled down to the (a) side, and the transfer substrate A is inserted into the carrier by fitting guide grooves 6 on both outsides of the substrate to desired guide rails of the wafer carrier. The holding lever is advanced to the (b) side along an advance-retreat guide recess groove 9 at a point where the insertion end of the substrate strikes on a wafer reception bar and stops, and then pulled up to the (c) side by means of the knob at the terminal of its dead end. Since the catching claw 7a of the holding lever catches the rear end of the wafer, this transfers to the position of the one-dot chain line and fixed to the substrate by drawing the holding lever to the (d) side.
