摘要： An optical switch is provided in which the difference of the optical loss due to the difference of optical path can be reduced. The optical switch comprises the first switching parts 2A–2D and the second switching parts 3A–3D. The first switching parts 2A–2D each comprise: a planar waveguide device 4 in which four coupling optical waveguides 5a–5d and an input optical waveguide 6 are provided; and reflection mirrors 8a–8d for reflecting a light signal incident from the input optical waveguide 6 to the respective coupling optical waveguides 5a–5d, respectively. The second switching parts 3A–3D each comprise: a planar waveguide device 9 in which coupling optical waveguides 10a–10d and an output optical waveguide 11 are provided; and reflection mirrors 13a–13d for reflecting a light signal incident from the respective coupling optical waveguides 10a–10d to the output optical waveguide 11. The optical switch is provided with 16 optical fibers 20 for connecting the coupling optical waveguides 5a–5d of the first switching parts 2A–2D to the different second coupling optical waveguides 10a–10d of the second switching parts 3A–3D, respectively.

摘要： An optical switch 1 has a plane waveguide 2 provided with optical waveguide 3, and an actuator structure 5 including a beamlike member 6 supported in a doubly supported manner on the plane waveguide 2. A mirror 10 for shutting out light passing on the optical waveguide 3 is provided in the central region of the beamlike member 6. Interconnecting members 12 extending in the longitudinal direction of the beamlike member 6 are coupled to the both ends of the beamlike member 6. The interconnecting members 12 preliminarily exert a compressive force on the beamlike member 6 so as to deflect the beamlike member 6 with compression stress in an initial state in which the mirror 10 is located at a position where the mirror allows the light passing on the optical waveguide 3 to pass or at a position where the mirror shuts out the light passing on the optical waveguide 3.

摘要： A high performance radial anisotropic cylinder-shape ferrite magnet for use in a motor to lower its noise and enable miniaturization thereof is formed of an integrated one-piece body formed of sintered Sr and/or Ba ferrite powders and has an axially-extending slit that is created before the body is sintered to reduce internal stress due to shrinkage. The slit can extend in parallel to both the axial and radial directions of the body, diagonally to both the axial and radial directions, or diagonally to the radial direction and parallel to the axial direction. The slit can be filled with a resin material.
