摘要： PROBLEM TO BE SOLVED: To provide a method of connecting an optical waveguide and an optical fiber, a method that is inexpensive and has low insertion loss as well as low return loss, and also to provide an optical module.
SOLUTION: In the method of connecting an optical waveguide and an optical fiber; in an optical circuit in which a single coated optical fiber and two or more optical fibers of a coated optical fiber ribbon are fixed in V grooves 24 formed on a waveguide substrate, the tip end face 26 of the optical fibers is formed obliquely at a specific angle to the optical axis. In the end of the optical waveguide substrate, there are formed the V grooves in numbers equal to or more than those of the optical fibers. At least on the extension of one V groove, an optical waveguide core 25 is formed in the manner that the optical axis of the optical fiber placed in the V groove is nearly aligned with the optical axis of the optical waveguide. At the end of the V groove, a groove is formed that has a face with nearly the same angle as the one formed by the optical fiber and the optical axis, in the direction vertical to the optical axis, wherein the optical fiber is abutted against the optical waveguide and fixed with an adhesive.

SOLUTION: When forming the thin film on the surface of a sheet glass by using plural spray guns, and reciprocally moving the spray guns so as to be synchronized while spraying the chemicals on the surface of the traveling sheet glass at a high temperature, the intervals and swinging widths of neighboring spray guns are regulated so as to be the same, and the moving speeds of the spray guns moving so as to cross the traveling direction of the sheet glass are regulated so as not to form unevenness in the thickness of the film. Further, a means for removing excess chemical mist which causes the unevenness of the thickness of the film is installed to remove the chemical mist.

摘要： PROBLEM TO BE SOLVED: To form a metal compound coating layer that inhibits combustible gas to ignite or explode and prevents the coating layer from deteriorating. SOLUTION: An organometallic salt in powdery, gaseous or liquid form or a solution of a raw material for coating layer formation, for example, an organic or inorganic metal salt dissolved in an organic solvent is brought into contact with the surface of the heated substrate to prepare a metal compound layer by the thermal decomposition. In another case, the metallic salt includes an ignition-inhibitory component, or the ignition inhibitor is added to the metallic salt to form the coating layer of the metallic compound including the ignition-inhibiting component. Instead, the substrate surface is previously brought into contact with a powdery or liquid organometallic salt or the raw material for forming coating layer comprising an organic or inorganic metal salt dissolved in an organic solvent is brought into contact with the substrate and the organometallic layer is thermally decomposed, as the substrate is heated, to form the boating layer of the organo-metallic compound including the ignition-inhibitory component.
