摘要： In an encoder output method and a servo motor encoder according to the present invention, the number of signal lines is reduced by using common signal lines and common output terminals. In the encoder output method and the servo motor encoder, incremental signals (A, B, Z) and servo motor magnetic pole position detection signals (UE, VE, WE) are switchably output by a common driver (2) through a pair of timers and a multiplexer (30), or a pair of timers and two line drivers (60, 70) are selectively active or inactive, and common signal lines are used, thereby reducing the number of signal lines.

摘要： An improved optical fiber gyroscope is provided to determine the angular velocity of an optical system. A beam of light emitted from a coherent light source are split into first and second light components. The first light component is further split into third and fourth light components while the second light component is further split into fifth and sixth components. The third and fifth light components are passed through a coil-like optical fiber in opposite directions to each other while the fourth and sixth light components are passed through an optical modulator in opposite directions to each other. The third and fourth light components are made to be interfered in a photodetector while the fifth and sixth light components are made to be interfered in another photodetector. From the outputs of the photodetectors, the above angular velocity is determined.

摘要： A method of manufacturing a polymer coated single ferromagnetic particle is provided. The method includes hydrophobizing one single hydrophilic ferromagnetic particle by absorbing an aliphatic acid having a hydrophobic aliphatic group and a hydrophilic acid group onto the single ferromagnetic particle to obtain a single hydrophobic ferromagnetic particle; emulsifying the one single hydrophobic ferromagnetic particle with a monomer liquid comprising a nonionic surface activating agent which re-hydrophilizes the one single hydrophobic ferromagnetic particle, to obtain an emulsified liquid; adding a radical addition initiator to the emulsified liquid; and emulsion polymerizing the monomer by radical addition polymerization.
