    摘要： An optical branching device includes a main waveguide and a branching waveguide. A portion of the main waveguide is bent and the branching waveguide is placed close to the bent part of the main waveguide. The branching waveguide has a taper structure such that a width of the branching waveguide is gradually decreased in a propagation direction of light. A central axis of the branching waveguide is tilted from a line extended from a straight part of the main waveguide toward the direction X, or the bending direction of the main waveguide. An input end of the branching waveguide has a normal vector tilted from the central axis of the branching waveguide toward the direction Y, an opposite direction of the bending direction of the main waveguide. With above-mentioned structures, light radiated from the bent part of the main waveguide can be launched into the input end of the branching waveguide and transmitted through the branching waveguide efficiently.

    摘要： The accuracy of a measurement value obtained by a tire pressure detection device is lowered by a centrifugal force and an inertial force during travel. A pressure sensor (30) displaces a diaphragm (20) in its vertical direction (32) according to the pressure. The pressure sensor (30) is arranged in a tire (2) with the vertical direction (32) directed to a direction parallel to a rotation axis (34) instead of the tire circumferential direction or radial direction. The pressure sensor (30) is mounted onto a substrate with the vertical direction (32) of its diaphragm (20) directed in parallel to the substrate surface and the substrate is bonded to a tread portion of the tire (2) and a wheel rim portion while adjusting the vertical direction (32) of the diaphragm (20) with the direction of the rotation axis (34).
