Title: Electron beam welding method of alloy for bimetal
Inventor: TOMOTA KENJI
IPC: B23K15/00
Filed: 1980-06-30
Abstract: PURPOSE: To obtain a stable melted shape, by irradiating an electron beam mostly on another bimetal alloy rather than the weld beveling surface, when a welding is made between a highly expanding alloy contaning Mn as the principal ingredient and another bimetal alloy.  
     CONSTITUTION: A highly expanding alloy 1 for bimetal consisting essentially of Mn and another bimetal alloy 2 are welded by a electron beam 4 under such condition that both alloys are fitted together at the weld beveling surface 5. In this case, most of the beam 4 is irradiated onto the bimetal alloy 2 side rather than the beveling surface 5. When the deviation 6 is adequately selected, and alloy 1 is also melted by the melting heat of alloy 2, and thus a metallic evaporation which will be produced when the beam 4 is irradiated directly upon the alloy 1, can be prevented. Moreover, when the dimension 6 is adequately selected, an optional melting depth can be obtained and a stable melted shape which does not deviate to the alloy 1 can be obtained. In this way, bimetals are formed by welding the peripheral part of fitted surface of alloys 1 and 2 and then, by performing a rolling and forming.

Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of an equipment by providing a driving current control means making the 1st driving current value of a correction driving means when an image blurring correction means is in a non-locking state different from the 2nd driving current value of the correction driving means in a transition state where the image blurring correction means is shifted from a locking state to the non-locking state. SOLUTION: When instruction for starting image blurring correction operation is communicated to an MPU 31, the MPU 31 converts battery voltage VBAT into digital data. The MPU 31 inputs a 1st value corresponding to the digital data to a D/A converter 50. Analog voltage corresponding to the 1st value is generated at the output of the converter 50. The MPU 31 controls a coil driver 35 so as to energize a shift coil. The MPU 31 controls a motor driver 34 to start to energize a step motor and simultaneously controls a timer to start operation. When the timer finishes counting for a specified time, the MPU 31 controls the motor driver 34 to stop energizing operation. Next, the MPU 31 sets a 2nd value larger than the 1st value at a parallel output port.
