摘要： A method of fabricating an optical switch including a stationary support member, a movable support member, and at least one pair of optical fibers, the pair of optical fibers being supported on the stationary and movable support members, respectively, so that an optical path between optical fibers is changed by moving the movable support member. The method comprises the steps of preparing a guide with V-shaped grooves, securing at least one optical fiber element on the surface of the guide, bridging and fixing the guide on the stationary and movable support members, and separating the guide along at least a line extending between the stationary and movable support members. Thus, the guide and the optical fiber element is separated into a first part supported by the stationary support member and a second part supported by the movable support member, to constitute the optical switch having at least one pair of optical fibers.

摘要： An acceleration sensor including a cantilever beam having a free end to which a permanent magnet is attached. A pair of magnetic sensors, each comprising a barber-pole type magnetoresistive sensing element, is arranged in symmetrically spaced and opposed relationship and in a common plane extending parallel to the magnetic flux of the permanent magnet with respect to respective, opposite sides of the magnet. The cantilever is bent and the magnet is moved accordingly in response to an acceleration force, which is detected as outputs from the magnetoresistive sensing elements.

摘要： A reflection type liquid crystal apparatus comprising a liquid crystal panel (26) composed of a pair of first and second opposed plates (30, 32) for accommodating a liquid crystal (34) therebetween. A reflecting layer (28) is provided in the inner surface of the second plate, and the first plate is transparent. A common electrode (36) is provided in the first plate, and picture electrodes (38) are located in the second plate. A beam splitter (24) is located in front of the liquid crystal panel (26) for supplying polarized light to the first plate and for selectively transmitting polarized light emerging from the liquid crystal panel (24). The liquid crystal (34) comprises a nematic liquid crystal material having a positive birefringence and arranged in a homogeneous orientation with a constant director (n). This arrangement being such that incident polarized light is propagated in the liquid crystal in a double refraction mode with a first birefringence value and the emerging polarized light thereof is substantially transmitted by the second polarizer means (24) when a voltage is not applied to the liquid crystal; and incident polarized light is propagated in the liquid crystal in a double refraction mode with a second birefringence value smaller than the first birefringence value and the emerging polarized light thereof is not substantially transmitted by the second polarizer means (24) when a voltage is applied to the liquid crystal.
