The invention relates to the technical field of mechanical transmission, and provides a coupling capable of clamping different shaft diameters and invariable in rotational inertia, which comprises an upper jaw adjusting mechanism, a middle rotational inertia compensation mechanism and a lower jaw adjusting mechanism, the upper clamping jaw adjusting mechanism comprises a first chuck, a first plane gear ring and a plurality of adjusting units. The first plane gear ring sleeves the outer side of the first chuck; the multiple adjusting units are evenly distributed in the circumferential direction of the first chuck, and each adjusting unit is located in the radial direction of the first chuck. The adjusting unit comprises a first bevel gear, a first worm and a clamping jaw; the first bevel gear is meshed with the first plane gear ring; the first bevel gear is rigidly connected with the first worm; a threaded hole is formed in the clamping jaw, the first worm penetrates through the clamping jaw, and the first worm is meshed with the threaded hole of the clamping jaw. The clamping device can clamp rotating shafts with different shaft diameters, and it is guaranteed that the rotational inertia is not changed when the rotating shafts with the different shaft diameters are clamped.

The utility model relates to the technical field of hoisting tools, and discloses an adjustable steel bar truss floor support plate hoisting tool which comprises a hoisting frame, telescopic frames are inserted into the end parts of the two ends of the hoisting frame, the telescopic frames and the inner wall of the hoisting frame are mounted in a sliding manner, and fixing plates are fixedly mounted at the adjacent ends of the telescopic frames. When the distance of the expansion bracket is reduced, the size of the steel wire rope can be adjusted through the ascending motion of the auxiliary rope wheel, and the distance of the steel wire rope can be adjusted through the descending motion of the auxiliary rope wheel, on the contrary, the size of the steel wire rope can be adjusted through the descending motion of the auxiliary rope wheel. The hoisting height of the steel wire rope is not changed, so that the subsequent assembly work is prevented from being influenced by the change of the height of the hoisted steel bar truss floor support plate, and the use by workers is facilitated.

The present invention provides a substrate bonding method and substrate, belonging to the field of semiconductor technology. The substrate bonding method is to open each clamping jaw in turn and remove the gasket at the position of the clamping jaw after aligning the two substrates and before heating and pressing for bonding, and then close and lock until all the gaskets are removed and then pressurized and heated to complete the bonding. The substrate bonding method described in the present invention is a method of removing the gaskets one by one in the open state of the clamping jaws, which can not only reduce the invalid area, but also avoid the misalignment caused by the removal of the gaskets, thereby improving the yield rate. At the same time, the height position of the gasket will not change, and the process of adjusting the height of the gasket in the next alignment process is omitted, thereby improving the working efficiency of the bonding.

The present invention relates to the field of communications. A method for generating a Cn value by a generic mapping procedure (GMP) mapping in an optical transport network (OTN), the method comprising: in each cycle, counting rate information statistical values of an opposite-end signal and a local low-order ODU signal, respectively; starting from the second cycle, producing a difference value in each cycle; comparing the difference of each cycle and a filter result of a previous cycle, to obtain a filter difference; amplifying the filter difference to a pre-configured filter coefficient times to acquire an adjustment value; accumulating the adjustment value of each cycle and the adjustment value of the previous cycle to acquire an integral value; when the integral value of one cycle is greater than 255, the filter value is 1, and the Cn value of the cycle = nominal Cn value + filter value; otherwise, the filter value is 0, and the Cn value of the cycle = nominal Cn value. According to the present invention, the circuit consumes a small amount of resource, and the circuit structure will not change due to changes to the mapping object, thus reducing jittering of the Cn value.
