摘要： A feedback control device capable of continuously performing high-accuracy, stable control even in cases where any of multiple controllers for controlling a controlled system becomes incapable of control action. A controller (master controller) generates control data for stably controlling a heater by feedback control, controls the heater in accordance with the control data, and sends the control data to the other controller (slave controller). The slave controller receives the control data from the master controller but does not control the heater while the master controller is operating normally. If the master controller develops anomaly and becomes incapable of normal control action, the slave controller initiates feedback control of the heater in accordance with the control data received from the master controller immediately before the anomaly occurred, and controls the heater thereafter in accordance with control data generated thereby.

摘要： A diffusion part diffuses an optical signal emitted from the end face of an optical fiber of an input light guide. An input reflection part reflects the optical signal diffused by the diffusion part in the direction of an output reflection part. A transparent medium guides the optical signal reflected by the input reflection part in the direction of the output reflection part. Output reflection parts reflect optical signals guided in the transparent media in the direction of optical fibers of output light guides. The optical signal reflected by the output reflection part is incident on the end face of the optical fiber and is transmitted over the output light guide.

摘要： In the thunder cloud observation system of the present invention, the vertical direction accumulated water content (VIL) is calculated by the VIL arithmetic operation unit from echo strength data obtained by the climate radar, the echo peak temperature is obtained by the echo peak temperature arithmetic operation unit with reference to altitude-temperature comparison data on the basis of high atmospheric climate data, the precipitation area is determined by the area determination unit from the VIL data, and the thunder cloud area generated within the precipitation area is identified from the echo peak temperature data. The thunder cloud area determined by the area determination unit is subjected to the correlation processes in terms of distance and overlapping area by the identification/tracking process unit, thus performing the identification/tracking, and the results of the processes of the area judgment unit and the identification/tracking process unit are displayed in the image display unit.

摘要： A bypass controller (30) controls ON/OFF of a three-way electromagnetic valve (62) according to a detection value of a cam chamber sensor (12a). When the cam chamber sensor (12a) detects a viscosity of lubricant exceeding a predetermined allowable value, the three-way electromagnetic valve (62) is controlled to turn ON so that the output side of an oil separator (13) communicates with a bypass route (61). The pressure in the cam chamber (12) is reduced to or below the atmospheric pressure by suction of a compressor (16) with a check valve (14) regulating the pressure in the cam chamber (12) to the atmospheric pressure or above in the bypassed state. When the detection value of the viscosity of the lubricant output by the cam chamber sensor (12a) has become the predetermined allowable value or below, the three-way electromagnetic valve (62) is controlled to turn OFF so that the output side of the oil separator (13) communicates with the check valve (14) and the bypass route (61) is cut off.

摘要： An optical transmission device improved in optical coupling loss between light guides and optical elements and excelling in efficiency of light utilization is provided with light guides having light incidence/emission sections on plural stepped portions, a substrate that fixes the light guides, and light receiving elements and light emitting elements arranged on the substrate to match the light incidence/emission sections of the light guides. The light receiving elements and the light emitting elements are arranged on the substrate by use of optical connectors. Coefficients of linear expansion and the rates of dimensional variation due to water absorption (or alternatively due to water absorption rates) of the light guides and the substrate here are substantially equalized.

摘要： The disclosure relates to a novel arrangement of a combustion chamber for diesel engines, which is defined by an inner wall including a fuel-impinging area formed of a metallic material, and a remaining area which at least partly is formed of a ceramic material or a like heat-resisting material. The arrangement serves to achieve an effective exhaust gas clarification, including the minimization of NOx emission, and to realize increased power output and reduced fuel consumption of the engine.
