Title: Electron beam welding method
Inventor: NAKADA TOSHIHIKO
IPC: B23K15/00
Filed: 1981-03-27
Abstract: PURPOSE:To supply a filler wire to the center of the beam in the deep part of a groove in the stage of performing electron beam welding while feeding said wire by specifying the entrance angle of the wire and feeding the wire while winding the same on a grooved roll. CONSTITUTION:After a filler wire 2 wound on a spool 3 is once wound on a  grooved roll 6, it is fed in the direction of a wire guide 5 by means of opposite  rolls 4, 4 for feeding. The entrance angle of the wire 2 to the rolls 4, 4 (the angle that the common tangent S of the rolls 4, 4 and the entrance direction of  the wire assume) theta is set at >=5 deg., so that sufficient bending in one direction is given to the wire 2. Hence, the wire 2 can be inserted smoothly down into the  deep part of the groove so as to conform to the surface of molten metal, and  the troubles owing to the contact with the molten metal are prevented. Even  more, the wire 2 is directed to the center of an electron beam A.

Title: Auxiliary steering device of vehicle
Inventor: MORI KAZUNORI
IPC: B62D7/14
Filed: 1990-03-01
Abstract: PURPOSE:To slow the behavior of a vehicle so as to avoid such an accident as disturbing safety operation of the vehicle by varying the controlling state of auxiliary steering so that the behavior gain of the vehicle for steering is lowered in the case of long continuous operation. CONSTITUTION:In response to a signal from a mode select switch 20 a controller 17 detects that the automatic mode is selected, and then varies a stationary yawing rate gain to a proper value through a control program. When a vehicle is stopped an operation timer is reset, while when the vehicle is operated the operation timer is counted up to measure the duration of operation and also the stationary yawing rate gain is lowered according to the duration of operation. The controller 17 then computes the steering angle of rear wheels using the stationary yawing rate gain and steers the rear wheels 2L, 2R; while the automatic mode is selected the stationary yawing rate gain therefore decreases as operation time elapses, and so the behavior of the vehicle for steering is slowed as the operation time elapses.
