摘要： A sealed-type automatic tensioner has a body assembly composed of upper and lower tubular bodies held in threaded engagement with each other, a tubular plunger slidably disposed in the body assembly, a piston slidably disposed in the tubular plunger and having a portion extending slidably through a hole in a top wall of the upper tubular body. The lower tubular body and the tubular plunger jointly define a larger-diameter hydraulic chamber, and the tubular plunger and the piston jointly define a smaller-diameter hydraulic chamber. A bottom wall of the tubular plunger has an aperture through which the larger- and smaller-diameter chambers communicate with each other. A compression coil spring is disposed in the first tubular body and acts between the top wall of the upper tubular body and the tubular plunger for normally urging the tubular plunger to move into the larger-diameter chamber.

摘要： A spot welding control method is disclosed wherein the welding current and welding time are controlled, in response to changes in the shape of the point of the electrode tip. At each weld point, the lowest value of the varying resistance between the electrode tips is detected in an initial welding period, and each detected lowest value is successively held and stored. At each weld point, a running average of the lowest resistance values is computed, bases on the resistance date of a group of weld points composed of the weld point just completed through a number of preceding weld points, the number of which is preset. The weld conditions are changed from one set of predetermined parameters to another when the computed average reaches the then prevailing threshold limit, following which the threshold is reset. The thresholds are preset depending upon the degree of wear of the electrode tip, whereby welding is continued under newly-selected weld conditions corresponding to the present threshold.
摘要翻译：公开了一种点焊控制方法，其中响应于电极尖端的形状的变化来控制焊接电流和焊接时间。在每个焊接点处，在初始焊接期间检测电极头之间的变化电阻的最小值，并且连续保持并存储每个检测到的最低值。在每个焊接点处，计算最低电阻值的运行平均值，基于由刚刚通过多个先前焊接点完成的焊接点组成的一组焊接点的阻力日期，其数量是预设的。当计算出的平均值达到当时的主要阈值极限时，焊接条件从一组预定参数改变到另一组参数，然后复位阈值。根据电极头的磨损程度来预设阈值，由此在对应于当前阈值的新选择的焊接条件下继续焊接。

摘要： A tensioner for vehicle belts produces reduced rattling because radial forces are not transferred to the plunger. A tensioner body has a columnar hole extending from an open end toward a closed end. The plunger is fitted into the columnar hole and separates the columnar hole into first and second chambers. The plunger has sufficient clearance with respect to the body to permit restricted passage of fluid between the chambers. A rod pressed by the belt extends into the columnar hole and presses the plunger against the biasing force of a spring. In order to reduce the transfer of radial forces from the rod to the plunger, either the lower surface of the rod or the upper surface of the plunger is formed in a semi-spherical shape.
