Abstract: PROBLEM TO BE SOLVED: To make a mass part large at an acceleration-detecting part thereby improving detection accuracy for an acceleration, by forming an angular velocity sensor and an acceleration sensor at a semiconductor substrate so that the mass part of the acceleration sensor is like a rectangular frame surrounding the angular velocity sensor. SOLUTION: When an acceleration is applied in a positive direction, a left inertial force is applied to a mass part 1 relative to a common substrate 9 of the motion sensor. As a result, a rectangular wave-like mass part-supporting body 21 or mass part-supporting body 24 is deformed, and the mass part 1 is moved leftward. When the mass part 1 is moved leftward, a movable comb- like electrode is moved leftward at an X-direction acceleration detection part 31 and an X-direction acceleration detection part 33, whereby a variable capacitance composed of the movable comb-like electrode and a fixed comb-like electrode is increased or decreased. It can be so recognized on the basis of the increase or decrease of the variable capacitances of both X-direction acceleration detection parts 31, 33 that the acceleration is applied in the positive X direction.

Title: Double refractive diffraction grating type polarizer and its production
Inventor: OBA AKITOMO
IPC: G02B5/30
Filed: 1992-03-04
Abstract: PURPOSE:To provide a high extinction ratio by setting the width of ion exchange regions wider than half the period of a diffraction grating and setting the width of dielectric films narrower than half the period of the diffraction grating. CONSTITUTION:The diffraction grating consisting of the periodically provided ion exchange regions 2 is formed on the main surface of a crystal substrate 1 having optical anisotropy and the dielectric films 3 narrower than the width of the ion exchange regions 3 are provided at the center on the ion exchange regions 2. The width of the ion exchange regions 2 is set wider than half 4 the period of the diffraction grating and the width of the dielectric films 3 is set narrower than the half 4. Namely, the polarizer separates ordinary light and extraordinary light to 0 order diffracted light and first or higher order diffracted light, respectively. The transmission of the extraordinary light is suppressed by setting the line and space ratio of the grating at 1:1 in average between the dielectric films 3 and the ion exchange regions 2. On the other hand, the extinction ratio of the first order light is determined by the diffracted light quantity of the ordinary light and the period of the grating is half the intrinsic period and, therefore, the diffraction angle is doubled. Consequently, the high extinction ratio is obtd.
