Abstract: A microreactor comprises a reaction chamber, into which prescribed materials are introduced, a production chamber, and a channel for connecting the reaction chamber and the production chamber together. A plurality of temperature adjusting devices (e.g., Peltier elements), each of which can be independently controlled in temperature, are arranged at prescribed positions with prescribed distances therebetween on a substrate in proximity to the reaction chamber, the production chamber, or the channel. Herein, the reaction chamber causes reaction of the materials in response to differences of boiling points, differences of state changes, or difference of solubility, thus producing a new substance, which is transmitted from the reaction chamber to the production chamber via the channel while being adequately controlled in temperature.

Abstract: An optical fiber coupler reinforcing member comprises an approximately rectangular member formed by a hard material, and has a flat surface along the longitudinal direction thereof. In addition, the shape thereof in cross-section is a hexagonal shape which inscribes a cylindrical member. Furthermore, a recess having a U-shaped cross-section is formed in the longitudinal direction of the above-mentioned approximately rectangular member and houses coupling section. The coupling section housed within the recess is fixed at both ends of the recess by an adhesive or the like. In addition, both ends of the inner wall surface of the recess have been given bevel sections. As a result, the optical fiber coupler reinforcing member having high reliability at low cost, with which the strength with respect to external force is improved and with which processability and the assembly operations of the optical fiber coupler are easy, are provided.

Abstract: A magnetic detecting apparatus including a magnetic sensor for detecting the displacement of a member which is detected by a variation in the voltage, a sampler for sampling the voltage detected by the magnetic sensor at the required period, and a voltage power supplier for supplying the required power supply voltage to the magnetic sensor only while the sampler samples the voltage.
