    摘要： An external cavity type semiconductor laser that has a larger output and a more excellent single mode characteristic than a conventional external cavity type semiconductor laser is provided. The external cavity type semiconductor laser has a laser diode 11, a window glass 16, a grating, and a lens. The external cavity type semiconductor laser has several modifications over the conventional one. A first modification is in that the window glass 16 is inclined to a beam emission surface 19 of a laser diode 11 for a predetermined angle. A second modification is in that arrangements of the laser diode 11 and so forth are adjusted so that an S wave reaches the grating. A third modification is in that when an output power of the laser diode 11 is 45 mW or less, a kink is suppressed. The other modifications are in that a reflectance of a beam emission surface of the laser diode 11, a numerical aperture of the lens, an external cavity length, and a reflectance of a first order beam of the grating are optimized to their proper values.

    摘要： A vibrating gyroscopic sensor including a vibrating gyroscopic sensor element including a cantilever vibrator that includes a piezoelectric film, a driving electrode, and a pair of detection electrodes on a first surface, and a support substrate on which the vibrating gyroscopic sensor element is mounted. The vibrating gyroscopic sensor element is mounted on the support substrate so that the first surface of the cantilever vibrator faces the support substrate. An area other than the first surface of the cantilever vibrator is defined as a laser processing area where a depression for adjusting the vibration characteristics of the cantilever vibrator is to be provided.

    摘要： A disc-shaped recording medium for which information signals are recorded and/or reproduced in a state in which a rotating recording and/or reproducing head is floated a pre-set distance from a signal recording region carrying surface of the disc-shaped recording medium. The disc-shaped recording medium has an area radially outside of the outer perimeter of center opening by at least 0.1 mm clamped by a clamp mechanism. This area is coplanar as each surface of the disc-shaped recording medium carrying the signal recording region. It is possible in this manner to prevent eccentricity of the rotating disc-shaped recording medium and consequent collision of the recording and/or reproducing head against the disc-shaped recording medium.
