    摘要： In an optical attenuator, there are a first optical waveguide 3A connected to an input optical waveguide 1, a second optical waveguide 3B connected to an output optical waveguide 2 and a connecting optical waveguide 4, which are connected with each other in series. A first recess 13A and a second recess 13B are formed in a positional relationship of opposite directions with respect to an axial direction of an optic axis of light that is inputted through the input optical waveguide 1, transmitted through the first optical waveguide 3A, the connecting optical waveguide 4 and the second optical waveguide 3B and outputted from the output optical waveguide 2. Further, a first optical attenuating heater 6A and a second optical attenuating heater 6B are arranged so as to produce opposite refractive index distributions in the axial direction of the optic axis of the light that is inputted through the input optical waveguide 1, transmitted through the first optical waveguide 3A, the connecting optical waveguide 4 and the second optical waveguide 3B and outputted from the output optical waveguide 2, in the first optical waveguide 3A and the second optical waveguide 3B.

    摘要： In producing high-quality steel with use of copper-containing steel scraps as an iron source, the copper-containing steel scraps are melted with addition of carbon to produce hot metal for steelmaking, then, copper contained in the hot metal is removed by sulfur-containing flux, and sulfur contained in the hot metal is removed. With this method, the copper in the steel scraps can be removed efficiently and without the need for large facilities. Preferably, the sulfur-containing flux used is flux having Na2S as the main component. The treatment for removing copper in the hot metal is preferably carried out with use of refining equipment with mechanical stirrer or by the flux injecting method. Besides, it is preferable that a shaft furnace having a coke bed formed inside is used to produce hot metal having a higher concentration of sulfur for the copper removal treatment.

    摘要： To improve thermal insulation, a thermal infrared sensing element is carried on a sensor mount of a porous material and is spaced upwardly from a substrate by means of anchor studs projecting on the substrate. The sensor mount is formed with a pair of coplanar beams carry thereon leads extending from the sensing element. The leads and the beams are secured to the upper ends of the anchor studs to hold the sensing element at a predetermined height above the substrate. The beams and the leads are combined with each other by intermolecular adhesion such that the sensing element as well as the sensor mount can be altogether supported to the anchor studs.

    摘要： A light leakage generation portion is formed at a portion of connection by connecting two optical fibers so that a refractive index distribution of the optical fibers in the portion of connection is different from a refractive index distribution thereof in another portion, and a part of a light propagating a core of one optical fiber (optical fiber on the right side in the example shown) is leaked into a clad of the other optical fiber (optical fiber on the left side in the example shown). A light receiving element chip adheres to an outer circumferential surface of the clad of the other optical fiber via a transparent adhesive layer constituted by transparent adhesive so as to detect light leaked by the light leakage generation portion.
