An apparatus for tensioning a belt consisting of a tensioner arm having an idler pulley for engagement with a surface of a drive belt, structure for mounting the tensioner arm to a suppport for pivoting movement about a pivot axis in first and second opposite directions, and structure for biasing the tensioner arm in one of the first and second directions. The mounting structure includes first and second members with first and second relatively movable cooperating friction generating surface for damping rotation of the tensioner arm. At least a portion of one of the friction generating surfaces is concave opening towards the tensioner with at least one of the friction generating surfaces having at least a portion defined by other than a radius centered on the pivot axis of the tensioner arm to thereby produce a greater resistance to rotation of the tensioner arm in the other of the first and second directions than in the one of the first and second tensioner arm pivoting directions.

A data recording apparatus includes an acquisition unit configured to acquire a first type data and a second type data, and a recording unit configured to record the first type data or the second type data acquired by the acquisition unit in a recording medium. The recording unit refers to a first pointer which indicates a logical position regarding the first type data in the recording medium to determine a position to start recording the first type data based on the logical position indicated by the first pointer. The recording unit refers to a second pointer which indicates a logical position regarding the second type data in the recording medium to determine a position to start recording the second type data based on the logical position indicated by the second pointer.

摘要:
The object of this invention is to produce a monitor which can correctly distinguish normal from abnormal vibration using automatically selected monitoring features and algorithms. The monitor can be used with a variety of devices with different vibration characteristics. The monitor according to this invention has a sensor that detects the vibration of an object. The monitor is operated in learning mode when the object is vibrating normally. The waveform of the vibration detected by this sensor is sampled over an appropriate period and analyzed. The data for each sampling feature are subjected to statistical processing, and the data which evince slight change are extracted as monitoring features. A monitoring algorithm is automatically made for these monitoring features. The algorithm selected in learning mode are used to evaluate the vibration of an object when the monitor is in operating mode. The operator does not need to set up the algorithm, and can monitor the object with a more reliable algorithm than the conventional one selected by fixed monitoring features.

摘要:
A cellulose solution obtained by dissolving cellulose in an amine oxide solvent is formed in a film form, and the resulting cellulose solution is immersed in water or a poor solvent of the amine oxide solvent, so as to coagulate and regenerate the cellulose. The regenerated cellulose is washed with water to remove the amine oxide solvent, and then dried, thereby obtaining a cellulose film that is thin, uniform, and dense and has few impurities. An aluminum electrolytic capacitor, which has been down-sized and/or capacity enlarged, can be constructed by interleaving the obtained cellulose film as a separator between an anode aluminum foil and a cathode aluminum foil and winding them into a capacitor element, immersing the capacitor element in liquid electrolyte so as to impregnate it with the electrolyte, placing it in a case, and then sealing it closed and aging it.

Each acceleration sensor of an air bag system includes a sensing device, a communication device and an adjusting device. The sensing device generates a measurement signal, which indicates a measurement value of acceleration. The communication device performs two-way communication relative to a master ECU and each remaining one of the acceleration sensors of the air bag system. The adjusting device adjusts the measurement value based on a physical quantity application state of its own acceleration sensor and a physical quantity application state of each remaining one of the acceleration sensors.
