摘要： An optical fiber temperature sensor implements a temperature monitoring function in an interphase insulating material between sandwich bus bars. The optical fiber temperature sensor is formed by housing an optical fiber cable in a housing formed from an ultra-thin sheet made from an insulating material having insulation quality equal to or higher than interphase insulating material between sandwich bus bars. Multiple ultra-thin columnar members, each made from same material as is housing, are housed in multiple locations in housing. Multiple sensor rings are each formed by unfixedly winding a portion of optical fiber cable with a length equal to or longer than that corresponding to range resolution around corresponding one of ultra-thin columnar members. The multiple sensor rings measure temperatures in multiple locations. Silicone sealing is applied to housing side surfaces. All surfaces of housing are sealed with a hermetic sealing member made from a silicone-based liquid insulating material.

摘要： A log management module 10 acquires log data from a computer, temporarily stores the log data in a buffer, and writes the stored log data into a disk device 30a. When the log management module 10 detects a failure in the computer, the log management module 10 stops writing log data in the disk device 30a, and writes log data acquired after the failure is detected in a disk device 30b.

摘要： A ring spinning machine has a direct drive spindle rotatably supported by an upper bearing in a bolster and connected to a rotor of a spindle motor having an upper structure including upper coil end of a stator thereof. A ring is movable up and down along the spindle to guide a yarn to be wound on a bobbin carried by the spindle. The inside diameter of the ring is determined in relation to the size of the upper structure of the spindle motor such that the upper structure can be received at least partially in the ring when the ring is moved to the lower end of its vertical stroke. The length of the unsupported portion of the spindle is reduced to increase the critical or resonance speed of the spindle, thus enabling the spindle to operate at an increased speed.
