Title: Brazing method for iron material and aluminum material
Inventor: KANAI TOMIYOSHI
IPC: B23K35/28
Filed: 1990-03-30
Abstract: PURPOSE:To suppress the formation of the brittle alloy layer of a joint boundary and to make sufficient improvement in joining strength by using a brazing material consisting of an Al-Si-high-Zn system as a brazing material and executing a brazing at the specific temp. CONSTITUTION:Firstly, the brazing material 3 consisting of the Al-Si-high-Zn system is used and, therefore, only the m.p. of the brazing material is lowered while a good brazing property is maintained. Since Zn of a high concn. is incorporated into the brazing material, the wettability with an iron material 1 is good and the good joining is possible. The brazing is executed at <=570 deg.C by lowering the m.p. of the brazing material 3 while such brazing property is assured and, therefore, the formation of the brittle alloy layer of an FeAl3 system at the joint boundary of the iron material 1 and an aluminum material 2 is suppressed or eliminated. The degradation in the joint strength of both members by the presence of the alloy layer is consequently prevented and the brazed parts having the excellent strength are provided.

Title: Controller for synchronous motor
Inventor: TATARA SHINJI
IPC: H02P27/04
Filed: 1991-04-19
Abstract: PURPOSE:To get a controller of a synchronous motor which operates stably without becoming uncontrollable or torque shortage by providing a compensating means for getting a field current command which has increased more than a field current command. CONSTITUTION:A field current compensator 30 compensates a field current command i'f so as to get an actual field current command if2. That is, in case that the field current reference i'f is smaller than the lowest field current limit value ifMIN, it limits if2 to the value of ifMIN. This way, the field current if, which has increased by the lowest field current limit value ifMIN in the area where the field current if is small, is input into a magnetic flux computing element 6, and a d-axis current i'd increases by the amount of the increased field current. This increase is offset as demagnetizing action with the magnetic flux by the increase of the field current i'f, so it can be controlled without increasing the magnetic flux. Hereby, stable speed control can be performed without becoming uncontrollable or torque shortage.
