  working stroke
As an example of the power of this technique, here we focus on some recent results, revealing the performance of the working stroke in at least two distinct steps also in skeletal muscle myosin.
      
This asymmetry can be reconciled with the predictions of Huxley's original cross-bridge mechanism by incorporating the recent suggestion that myosin heads can interact with multiple actin binding sites during a single 'working' stroke.
      
Shortening at high speed, preventing most of cross-bridges from undergoing the relatively fast (100 s-1) detachment/reattachment process, uncovers a rate limiting step in the cycle at the end of the 12 nm working stroke.
      
Under sarcomere length-clamp conditions, the quick phase of tension recovery following each step in the staircase is the manifestation of the working stroke by synchronized cross-bridges.
      
With the increase in shortening velocity a progressively larger fraction of interacting cross-bridges remains in the AM-ADP-P state throughout the working stroke and the sliding distance for interaction is about 11 nm.

In this paper the working stroke of a screw press is onalyzed, leading to for- mulas for the determination of the maximum stress in its frame. The working stroke is considered to consist of two successive stages: (1)the stage of plastic deformation of the workpiece and (2) the stage of braking the flywheel of the press to a stop. Since the maximum force Pm acting upon the frame may accidentally occur at the end of the second stage of the working stroke when there is no stock in the die. the...

In this paper the working stroke of a screw press is onalyzed, leading to for- mulas for the determination of the maximum stress in its frame. The working stroke is considered to consist of two successive stages: (1)the stage of plastic deformation of the workpiece and (2) the stage of braking the flywheel of the press to a stop. Since the maximum force Pm acting upon the frame may accidentally occur at the end of the second stage of the working stroke when there is no stock in the die. the value Pm is required in the calculation of the frame strength. The strength calculation for the integral closed-type frame of a screw press then proceeds as follows: (1) Drawing the bending moment diagram with the unknown Pm (being in nature a statically indeterminate problem with respect, to the internal bending moment, this may be solved by means of the canonical equations of the force method); (2) Calculating the strain energy stored up in the frame and in the threaded spindle at well as the expended friction work during the whole working stroke, then determining the maximum load Pm; (3) Supplying the bending moment diagram with numerical data in order to find where the maximum stress in the frame exists and check up whether it is within the magnitude of the safe stress of the frame material.

The device for driving flat in the flat grinding machine is composed essentially of a slider-crank mechanism and two rotating guide mechanisms. It is found that, kinematically, the combination of a slider-crank mechanism and one of the rotating guide mechanisms may be equated approximately to a sine mechanism, and that the above-mentioned combination, in association with the other rotating guide mechanism, may be useful in creating approximately uniform motion for its output member in its working stroke....

The device for driving flat in the flat grinding machine is composed essentially of a slider-crank mechanism and two rotating guide mechanisms. It is found that, kinematically, the combination of a slider-crank mechanism and one of the rotating guide mechanisms may be equated approximately to a sine mechanism, and that the above-mentioned combination, in association with the other rotating guide mechanism, may be useful in creating approximately uniform motion for its output member in its working stroke. To this end, the size parameters, the rate rations and the relative phase positions of these mechanisms are defined in the article.The author also derives a formula for calculating the velocity of the flats. Meanwhile consultative discussions or criticisms on the previous similar formulae are proposed here.Based on the results of such research, the author has analysed size parameters of the existing flat grinding machine, and some of them have been found unreasonable. Corrective measures to be adopted designing a new one have therefore been presented.

磨盖板机中的盖板传动装置由一个曲柄滑块机构和两个转动导杆机构等组合而成。研究表明,转动导杆机构与曲柄滑块机构的组合可与正弦机构在运动学上接近等价;而这套机构与另一个转动导杆机构的组合,可使从动件在工作行程内作近似的等速运动。为了实现这个要求,文中对上述各个机构的尺寸参数、转速比及相对位置作了规定。作者还导出了盖板速度的计算公式,同时对以往某些类似的公式提出商榷。在上述研究成果的基础上,作者对现有磨盖板机中的连杆机构的尺寸参数进行分析,找出其中不合理的部分,从而提出了改进方案。

As the working stroke of the telescopic sleeve cylinder is longer than that of the conventional, there is a clearance between the piston and cylinder bore as well as between the rod and guide sleeve which will cause cylinder break under heavy loading. The steady limiting stress of the whole unit in this condition therefore must be determined. The authior gives eight formulas calculating the limiting stresses of telescopic sleeve cylinders by equivalent method which have been proved to be simple, reliable...

As the working stroke of the telescopic sleeve cylinder is longer than that of the conventional, there is a clearance between the piston and cylinder bore as well as between the rod and guide sleeve which will cause cylinder break under heavy loading. The steady limiting stress of the whole unit in this condition therefore must be determined. The authior gives eight formulas calculating the limiting stresses of telescopic sleeve cylinders by equivalent method which have been proved to be simple, reliable and safe in calculating the limiting stresses of 1-4 stage telescopic sleeve cylinders.
