Abstract: A bonded body has a piezoelectric material substrate 11, a support substrate 13 bonded to the piezoelectric material substrate, and an outer peripheral processed part in which outer peripheral parts of the piezoelectric material substrate 11 and the support substrate 13 are inclined with respect to a main surface of the piezoelectric material substrate 11. The outer peripheral processed part includes a first inclined surface that is a surface that the piezoelectric material substrate 11 faces, and a second inclined surface that is on a plane extending from the first inclined surface toward the outer peripheral part and that is a surface that the support substrate 13 faces. Consequently, a bonded body in which no corners are formed on the outer peripheral part and fracture and cracks are less likely to occur in the outer peripheral part in subsequent steps, and a method for producing a bonded body are provided.

Abstract: There is provided an information processing apparatus including a user information manager that registers, in a database, registered device information in which devices specified by a user from among devices capable of realizing functions by linking together are associated with the user, a recommended function determiner that acquires, from the database, function information in which the functions and the devices are associated, and determines recommended functions for the user on the basis of the function information and the registered device information, and a procedure information manager that acquires, from the database, procedure information indicating operating procedures for realizing a function that the user selects from among the recommended functions, and provides the procedure information to the user.

Abstract: An optical device includes a glass substrate provided with one or more V-shaped grooves and an optical fiber array having one or more optical fibers. The optical fiber array is fixed within the V-shaped grooves of the glass substrate using a fixing adhesive. As viewed from above, a first region Z1 (i.e., the region indicated by cross-hatching) and a second region Z2 are provided on the optical fiber array, and the fixing adhesive is applied within the first region Z1. A refractive index matching resin, providing refractive index matching at least with the optical fibers, is disposed in the second region Z2, wherein the second region Z2 may be surrounded by the first region Z1.
