摘要:
Noise produced by a chain drive mechanism is significantly reduced by providing rubber rings on the faces of a sprocket, with the rubber rings dimensioned so that they are not contacted by the chain as it comes into engagement with the sprocket. The rubber rings absorb sprocket vibration and are as effective in reducing noise as are conventional rubber rings which are contacted by link plates of a chain to alleviate the effects of collision shocks. Since the rings need not be contacted by the chain, it is possible to reduce their thicknesses so that the sprocket can be utilized in restricted spaces.

A method for measuring a directional of a body in a three-dimensional space defined by an X-axis (magnetic north), a Y-axis, and a Z-axis is proposed. A geomagnetic force along an x-axis, which is the direction towards which the body points and an x-axis tilt angle, which is an angle between the horizontal plane and the x-axis, are detected. The x-axis tilt angle is determined as a rotation angle, which an angle by which the x-axis needs to be rotated around the Y-axis so as to be in the XY-plane. An azimuth of the body is calculated from the geomagnetic force and the rotation angle.

摘要:
A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage branched from an exhaust pipe of the engine, which is opened by a switch-over valve at starting of the engine to introduce the exhaust gas such that the adsorbent adsorbs unburned HC in exhaust gas generated by the engine and is closed such that the adsorbent desorbs the adsorbed HC and the desorbed HC is thereafter recirculated at a position upstream of a catalyst. Based on the fact that the HC concentration rising time interval becomes short as the adsorbent degrades and adsorption capacity decrease, the time lapse since engine starting until the detected HC concentration exceeds a predetermined level is measured and is compared with a threshold value such that the adsorbent is discriminated to be degraded if the measured time lapse is less than the threshold value, thereby enabling to improve the discrimination accurately.

摘要:
A fiber of sea-islands phase separation wherein the sea component comprises a vinyl alcohol based polymer with high orientation and great crystallinity and the islands component comprises a water-insoluble cellulose based polymer with excellent absorptivity of alkaline solutions, thermal resistance and heat fusion resistance, and wherein the size of the islands is 0.03 to 10 .mu.m and the strength is 3 g/d or more, is readily disintegrated into a fibril of a diameter of 0.05 to 8 .mu.m when a mechanical stress is imposed onto the fiber wet in water.From the fibril with good hydrophilicity, high strength, great particle captivity and excellent reinforcing performance, and additionally with good absorptivity of alkaline solutions and great thermal resistance and heat fusion resistance, none of the fiber components therein is solubilized during fibrillation. Neither a beating process nor a beating solution causes foaming or environmental pollution.The fibril is extremely useful for use in separator sheets for alkaline batteries, reinforcing fibers of cement slate plates, reinforcing fibers of frictional materials and the like.
摘要:
A vinyl-alcohol-based polymer and vinyl-halide-based polymer are dissolved in a common organic solvent for them, a typical example of which is dimethylsulfoxide, to obtain a dope wherein a solution of the vinyl-halide-based polymer having a particle size of 1-50 .mu.m is present in the solution of the vinyl-alcohol-based polymer. This dope is spun into a low temperature solidifying bath comprising a solidifying solvent such as methanol, and the organic solvent. The resultant is subjected to extraction, drying, dry heat drawing, and optional heat shrinking or acetalization to obtain fiber. In the fiber thus obtained, the vinyl-alcohol-based polymer makes sea phases, and the vinyl-halide-based polymer makes island phases whose size is 0.1-3 .mu.m. The crystallinity degree of the vinyl-alcohol-based polymer is 65-85%.The polyvinyl-alcohol-based flame retardant fiber is useful for clothes, industrial materials, living materials and the like. It can be produced at low costs, and has excellent spinning stability and dimensional stability in hot water.
