Inventor: ETO TAKEHIKO
IPC: C22F1/047
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To produce an Al-Mg alloy good in formability by subjecting an Al-Mg alloy contg. a specified amt. of Mg to hot rolling, thereafter executing specified rolling including specified process annealing and then subjecting the same to specified stabilizing annealing. SOLUTION: An ingot obtd. by casting an Al-Mg alloy contg., by weight, 1.5 to 4% Mg is subjected to homogenizing heat treatment preferably at about 500 to 550 deg.C and is thereafter subjected to hot rolling at about 300 to 550 deg.C.

Title: Position detecting device
Inventor: NISHIDA YOICHI
IPC: G01D5/30
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To improve detecting resolution by increasing the ratio of the reflecting surface gradually toward one side of a relative moving direction, and arranging two or more pairs equal in the reflecting surface ratio, in a row with the adjacent reflecting surface and nonreflecting surface as a pair. SOLUTION: When a movable body 21 moves to the -X side, the right end of an irradiation area 23 starts coming to the reflecting surface 24, but at the same time, the left end is about to come off the reflecting surface 25. The excessive increase of reflected beams 26 is therefore negated to obtain stable sensor output. At this time, even in case the left end is about to come off a nonreflecting surface part 27, since the installation pitch itself of the reflecting surface is sufficiently small in relation to the irradiation area 23, there is little influence. When the movable body 21 moves to the +X side, the ratio of the reflecting surface occupying in an area this time is reduced in comparison to the irradiation area 23. Smaller sensor output than the -X side can therefore be obtained, and displacement of an X-direction can be recognized.  Output fluctuation during this period is a smooth change without unnecessary output fluctuation, so that a sensor output characteristic with high linearity can be obtained.
