摘要： PURPOSE:To align optical axes at a high speed by stopping movement when the quantity of received light of a photodetecting part changes from an increase to decrease and repeating the movement until the quantity of the received light of the photodetecting part attains a prescribed position when the movement stops. CONSTITUTION:A slight deviation in the optical axis arises even if the positional deviation is prevented by pressurization of a pressurizing lever 12 at the time of YAG laser welding. The optical axis is aligned to the point where the quantity of the light is max. within the movable range of an X-Y table 11 at this time. Namely, a control section 14 moves the X-Y table 11 first in a random direction and monitors the quantity of the received light of the photodetecting part 13. The control section moves the table in the direction 90 deg. with said direction if the quantity of the light does not increase. The control section 14 moves the moving direction to directions -90 deg., +45 deg., -135 deg., etc., until the increase in the quantity of the received light arises. Said section determines the point of the max. quantity of the received light and stops the movement at the point of the time when the quantity of the received light changes from the increase to the decrease. Laser light welding is executed to connect a flange part 5a and a stem 1 at the point of the time when the alignment of the optical axis is completed.

摘要： PURPOSE:To secure the alignment precision between optical axes of an optical semiconductor element and a fiber having a rounded end by checking the optical axis of the fiber having the rounded end after a first sticking process and performing readjustment to correct the position of the optical axis if necessary. CONSTITUTION:A base 14 to which a laser diode 13 is attached is stood on a stem 12, and the fiber having the rounded end and a fiber holder are supported by jigs, which can finely adjust them individually, to face the light emitting part of the laser diode 13. The laser diode 13 is caused to emit light, and this light is made incident on the fiber having the rounded end, and such position in X-Z directions is selected that the optical output emitted from the other end of the fiber having the rounded end is maximum. A solder is flowed to the clearance of the hole of the fiber holder to fix the fiber having the rounded end. The fiber holder is rubbed against a holder to correct the positional deviation of the optical axis by the similar method, and plural parts of the fiber holder are spot-welded to the holder base 17 with a YAG laser point by point while being subjected to position correction. Thus, the alignment precision between optical axes of the optical semiconductor element and the fiber having the rounded end.

摘要： PROBLEM TO BE SOLVED: To prevent accident in a board, improve efficiency of monitoring and checking, and facilitate abnormality judgment of current carrying function of the board. SOLUTION: A board 11 accommodates a heat source element causing heat generation inside a carbonate. A plurality of local temperature sensors 12 which are arranged in specified portions of the board 11 and measure temperature distribution at the specified portions, a sensor 13 for peripheral temperature which measures the peripheral temperature of the board 11, and a signal processing means 15 are installed. On the basis of the temperatures measured with the local temperature sensors 12 and the sensor 13 for peripheral temperature, data concerning the temperature rise at the specified portions of the board 11 are calculated. Difference data between the data concerning the temperature rise and data concerning temperature rise of the specified portions of the board at the time of normal operation are calculated. A correlation coefficient is introduced by applying Walsh transformation to the difference data. On the basis of change of the correlation coefficient, abnormality is judgment performed, and current flowing function of the board 11 is monitored.
