Abstract: PROBLEM TO BE SOLVED: To evaluate various characteristics simultaneously by integrating testers for various characteristics thereby enhancing the efficiency of the tester. SOLUTION: The tester comprises a rotary section 101 being driven through a motor such that a tensile test, a bending test and a strain test can be carried out, a control section 103 fixed to one side of the rotary section 101 and controlling the speed and the number of times of test being carried out, and an impact test section 102 fixed to the opposite side of the rotary section 101 and performing an impact test by falling a test piece while adjusting the height thereof freely. Since the tester evaluates the tensile characteristics, the bending characteristics, the strain characteristics, the impact characteristics, and the like, simultaneously, the measuring time can be shortened while reducing the labor and the mechanical characteristics can be evaluated efficiently and economically. Consequently, the mechanical characteristics can be evaluated accurately and reliably using a precisely manufactured tester.

Abstract: A multi-fibre connector for connecting an optical cable and a transmitter consists of an adapter (10) with orifices (12) into which a male component is inserted, a through passage and holes (11) in its upper and lower walls for an engaging element (23). The male component (20) has a through channel for the optical fibres and an end tip with a series of small holes for the optical fibre cores, providing protection and alignment. The connector incorporates protectors (30) for the optical cable, designed to surround its outer ends and protect it from breaking, while an inner sleeve (40) of triangular cross-section ensures alignment of the tip (25), which is made from a composition material of epoxy resin and carbon fibres. The carbon fibres are 0.7-0.9 mm long and comprise 25-35% of its weight.

Abstract: An optical waveguide platform and a manufacturing method thereof are provided to prevent an alignment error generated due to mask alignment after an optical waveguide making process, by forming an aligning mark necessary for bonding of a flip chip during an optical waveguide core forming process. An optical waveguide platform manufacturing method comprises the steps of: stacking a lower clad layer and a center core layer(13) on a substrate(100) in order; forming an optical waveguide core and an aligning mark(13c) at the same time by patterning and etching the center core layer; depositing a silica upper clad layer on the substrate having the optical waveguide core and the aligning mark; forming a trench(17) on the upper clad layer by etching a predetermined region defining the mounting position of a semiconductor chip, while exposing the lower clad layer; forming a terrace(18) functioning as the center for vertical alignment of the semiconductor chip, at the position different from where an uneven part of the aligning mark is formed, on a predetermined region of the bottom of the trench; and producing UBM(Under Bump Metal)(19) forming a solder pad and an electric wire, on the bottom of the trench where the aligning mark and the terrace are not formed.
