摘要： An optical waveguide device which can be connected with an optical fiber through a simple positioning adjustment. The optical waveguide device comprises a substrate, a first cladding with a uniform thickness formed on the substrate, a core formed on the first cladding, a recognizable thin layer formed on the first cladding on both sides of the core, and a second cladding formed on the first cladding so as to cover the core. The thin layer is parallel to the top surface of the substrate and defines a reference plane which is substantially in the same plane as the bottom surface of the core. Connection of the optical waveguide device with the optical fiber is achieved by bringing the reference plane into contact with a plane which is in a predetermined relative position to the optical fiber and only making a planar positioning adjustment with the planes held in contact.

摘要： A semiconductor laser module comprising a serial arrangement of a laser assembly for emitting a substantially collimated beam of light, an optical isolator assembly having an optical isolator housed in a tubular package for transmitting the collimated beam of light with less loss in a forward direction than in a reverse direction, and an optical fiber assembly having a lens for converging and directing the beam from the optical isolator assembly into an optical fiber. There is also disclosed a method of optimizing the forward loss and isolation characteristics of the optical isolator assembly through adjustment of its angular position about its optical axis which is set at an angle to that of the laser assembly. For such adjustment, not only the isolator assembly is made rotatable relative to the laser assembly, but also the optical isolator itself is made rotatable within limits relative to the tubular package of the isolator assembly.

摘要： Chemical strengthening treatment is performed by first providing a granular chemical strengthening salt so as to prevent spread in atmosphere at the time of introduction of chemical strengthening salt in a treating vessel, introducing the chemical strengthening salt in a treating vessel, melting the chemical strengthening salt into molten chemical strengthening salt and bringing a glass disc into contact with the molten chemical strengthening salt. The granular chemical strengthening salt is, for example, one obtained by forming of a powdery chemical strengthening salt material into grains. A chemically strengthened glass substrate for magnetic disk can be obtained through the process of carrying out chemical strengthening treatment of magnetic disk glass substrates. A magnetic disk can be obtained by forming at least a magnetic layer on the chemically strengthened glass substrate for magnetic disk.

摘要： A method of producing a substrate for an information recording medium in which there is a step of washing and drying the substrate, which is also subjected to precision polishing. In the method, a correlation is preliminarily obtained between a contact angle of water on a surface of the substrate before the washing/drying step and a size (height) of protrusions attached to the surface of the substrate during the washing/drying step. The contact angle of water on the surface of the substrate before the washing/drying step is controlled so that the protrusions have a size (1) so as not to cause a hit when at least a recording layer is formed on the surface of the substrate and when a slider provided with a recording device and/or a reproducing device is made to run on a surface of the information recording medium, and (2) so as not to cause an error upon recording and/or reproducing the information recording medium.
