    摘要： An automatic test system useful for testing source synchronous devices at high speed. The data outputs of the device under test are routed to channel circuitry within the test system through coaxial cables. The test system includes a buffer amplifier on a device interface board to fan out the DATA CLOCK generated by the device under test to that channel circuitry. The interconnection between the buffer amplifier and the channel circuitry is provided through a coax with low dielectric constant, to compensate for the delay introduced by the buffer amplifier.

    摘要： A cutter drum for a web-cutting machine has a body having a cylindrical outer surface centered on an axis and formed with at least one seat having a radially outwardly directed floor face extending axially and helically of the axis and a tangentially directed rear face extending generally radially of the axis. A helically nonstraight blade lies flat on the floor face and has a front cutting edge lying radially outside the surface and a rear side confronting and spaced from the rear face of the seat. Blade bolts extending generally radially of the axis through the blade are seated in the body and secure the blade to the floor face with a possibility, when the blade bolts are not tightened, of limited movement of the blade on the floor face. A plurality of axially spaced spacer blocks each have a rear edge bearing against the rear face of the seat and a front edge bearing against the rear side of the blade. Respective block bolts extend through the blocks into the body and secure the blocks in the seat to the body.

    摘要翻译： 用于卷筒纸切割机的切割滚筒具有主体，该主体具有以轴线为中心的圆柱形外表面，并形成有至少一个座，该座具有径向向外定向的底面，该底面沿该轴线轴向和螺旋形延伸， 径向径向。 螺旋形非直角刀片平放在地板表面上，并且具有位于表面的径向外侧的前切割刃和与座椅的后表面相对并间隔开的后侧。 通过叶片大体上径向延伸的叶片螺栓位于主体中，并且当叶片螺栓未被紧固时，叶片在地板表面上受到有限的运动的可能性而将叶片固定在地面上。 多个轴向间隔开的隔离块各自具有抵靠座椅后表面的后边缘轴承和抵靠叶片后侧的前边缘。 各个块螺栓通过块体延伸到体内并将座椅中的块固定到身体上。

    摘要： Data can be processed in automatic test equipment by dividing the test sites into groups and processing each group using a corresponding processor in a group of processors. Sections of the test equipment can communicate via a tester bus to a particularly designed multi-stream switch. The multi-stream switch can communicates with a plurality of processors via a plurality of processor busses. Each of the processors can run a separate instance of test software without interfering with software running on any other of the processors. The inventive protocol can be embodied essentially in hardware that can be adapted to an existing infrastructure without requiring substantial modifications of existing hardware or software.
