Filed: 1990-11-15
Abstract: PURPOSE:To make the optical coupling efficiency and the reproducibility between a light- emitting part and a photodetection part good, to make this element small-sized and to manufac ture it easily by a method wherein the light-emitting part and the photodetection part are laminated and formed without being isolated spatially and the forbidden band width of a light-emitting layer is made larger than the forbidden band width of a photodetection layer. CONSTITUTION:A power supply, for bias use, which is set so as to make the side of a p-side ohmic electrode 8 positive is connected across the electrode 8 and an n-side ohmic electrode 10 and a bias current is applied. Then, light is emitted at a second semiconductor layer 3. One part of the light is transmitted through a third semiconductor layer 4 and it is incident on a part near a p-n junction (a junction part of a p-type and an n-type) by one layer 5 inside the layer 4 and by a fourth layer 6. Thereby, a light-emitting part 11 and a photodetection part 12 can be integrated without being isolated spatially; and each part can be controlled independently. The forbidden band width of the layer 4 is wider than the forbidden band width of the layer 3; and the forbidden band width of the layer 6 is smaller than the maximum light-emitting energy of the layer 3. As a result, an absorption coefficient in the part 12 becomes large. Consequently, the optical coupling efficiency and the reproducibility between the part 11 and the part 12 are made good, and this element can easily be made small-sized and manufactured.

Abstract: PURPOSE:To provide welding contact material, giving an electric contact piece having high welding strength and stable without floating or a recess in the contact material, by partially collapsing a wire projection provided on the middle in the lower surface longitudinal direction of the contact material. CONSTITUTION:A cross-section-circular wire projection, provided in the lower surface center in the longitudinal direction of an alloy-made contact material 13 having a slender shape, is collapsed leaving both ends and the middle part, to form multipoint projections 12, 12 and 12 for manufacturing welding contact material 13. In the obtained welding contact material 13, since a wire projection, provided in the lower surface in the longitudinal direction, is partially collapsed to form the multipoint projections 12, 12, and 12, welding current is diffused to be uniformly flowed in the multipoint projections 12, 12, and 12 for performing welding over an overall length when the welding contact material 13 is welded to base material even a length is longer by three times width or more. Consequently, welding strength is high and stable, and the contact material is pushedly pressed to an electrode over a whole surface at the time of welding, eliminating producing a recessed part on a surface.
