The resulting powder mixture is heated in an atmosphere of inert gas such as Ar or reducing gas such as H2, by which the oxide of rare ear metal is reduced by Ca to rare earth metal and alloyed with Fe, Co, etc., by means of diffusion and Ca is formed into CaO. The resulting cake-like reactional product mixture is heated in an N2- containing gas to undergo nitriding and is then subjected to water treatment to undergo the removal of unnecessary matter, such as CaO, by which the raw material powder for rare earth magnet consisting of an alloy of rare earth metal and magnetic metal, such as Fe and Co, is obtained. By using the inexpensive oxide as rare earth metal, the rare earth magnet alloy powder material can be inexpensively produced.

Filed: 1987-03-27
Abstract: PURPOSE:To facilitate and ensure the yarn end suction on the operation of yarn-end connection, by setting a movable parting piece between the yarn- separating nozzle and the false-twisting nozzle. CONSTITUTION:In a bind-spinning frame, a partition valve (a separating piece) is set movably in the reduced-pressure chamber 1d between the fiber-separating tube (nozzle) 2 and the false-twisting nozzle.

IPC: G01B11/24
Filed: 1993-03-09
Abstract: PURPOSE:To allow highly accurate inspection of outer view by providing a protrusion of known width and height on an inspection table, sampling images of the protrusion and an IC to be inspected and then operating the profile of lead wire with reference to the protrusion. CONSTITUTION:A reference protrusion 11 having width corresponding to the pitch of lead wires 1a of an object to be measured, i.e., an IC, having known size and height slightly shorter than the lead wire is provided on an inspection table 10. An image picked up by a video camera 4 is binarized 12 and stored 13 and eventually read out by an image processing section 14. An MPU 14a determines the image part of the protrusion 11 and the pixel position at the part of each lead wire 1a through template processing and calculates 15a the width and height of the protrusion 11, the pitch of the lead wire 1a, the floating of the table 10, and the number of each pixel which are then stored 14b and used in the calculation 15b of lead pitch P and floating amount H according to a predetermined formula. A pass/fail decision program 15c then decides whether the pitch P and the floating amount H come within a specific range read out from a memory 14b and displays 15 a failure if they deviate from the range. Since the fluctuation of image due to fluctuation of the quantity of light emitted from a light source 3 acts equally onto the protrusion 11, correct calculation results can be obtained.
