Abstract: PROBLEM TO BE SOLVED: To measure the insertion loss of a part to be measured with high precision by branching the output of a non-polarization light source, measuring one after passed to the part to be measured, and the other directly by non- polarization sensitive light detecting means, respectively. SOLUTION: A non-polarization light source 11 is formed by combining a high luminance LED with an optical fiber type depolarizer, and non- polarization sensitive optical power meters 13, 14 are formed by arranging optical fiber depolarizers just before the light detecting parts of general power meters. The output of the light source 11 is branched into two by an optical coupler 12, the respective outputs are measured directly by the two meters 13, 14 to determine the branching ratio of the coupler 12. An optical circuit part 18 to be measured is arranged in one circuit, and the outputs of both the circuits are measured by the meters 13, 14, respectively. The insertion loss of the part 18 is determined from the result.  Thus, it is not necessary to perform the reference measurement many times, a constant branching ratio can be regularly kept, and the insertion loss can be measured with high precision even when a degree of polarization is generated in the output light of the part 18.

The sputtering target after the vapor deposition is then blank-baked by increasing the temp. thereof up to 300 deg.C. The sputtering target after the blank baking is thereafter cooled in a vacuum. A brazing filler metal is set to a backing plate and the sputtering target is placed thereon and is heated until the target is heated up to 250 deg.C. The target is held for a specified period of time and is cooled, by which the backing plate and the target are joined. The space part in the adhered part is 3% in this case. The cracking, exfoliation, etc., are not generated when sputtering is executed.
