    • A thread control apparatus for a double chain stitch sewing machine of the present invention is applied to the case of sewing a cloth with a double chain stitch sewing machine having multiple needles, and forming a thread chain consecutively to the sewing end of the cloth. Two thread tensioning devices change over and apply mutually different thread tensions to needle threads and to a looper thread passed through a plurality of needles and a looper, respectively, when sewing the cloth and when forming a thread chain. An other looper thread tensioning device disposed in a thread route between a looper thread take-up device and the looper. The other looper thread tensioning device limits the draw-out amount of thread by pinching the looper thread from the looper thread take-up device to the looper side only when forming a thread chain, and therefore a tight thread chain may be securely formed when forming a thread chain. As such, the thread chain can be drawn out securely and stably even in high speed operation of the sewing machine.
    • 本发明的双链式针迹缝纫机的线程控制装置适用于用具有多针的双链式针迹缝纫机对布进行缝制的情况,并且连续地形成到针织物的缝纫端。 两个线张紧装置在缝合布和形成线链时,分别切换并施加相互不同的线张力到针线和穿过多根针和弯针的弯针线。 另一种弯针线张紧装置,设置在弯针线收卷装置和弯针之间的线路中。 另一个弯针线张紧装置仅在形成线链时将弯针线从弯针线收紧装置夹到弯针侧,从而限制线的拉出量,因此当成形时可以牢固地形成紧线 一条线链。 因此,即使在缝纫机的高速运转中,线链也能够稳定且稳定地拉出。

    • A process apparatus for processing semiconductor wafers. It includes a process vessel in which process solution is contained. In the process solution, the wafers are immersed and processed. A supply pipe extends from the process vessel to solution storing vessels. Component solutions are stored in the component solution storing vessels and supplied from them to the process vessel to keep the concentration of each component in process solution. A supply pump is attached to the supply pipe. Valves for adjusting the amount of each component supplied are attached to the supply pipe. The adjusting valves are electrically connected to a CPU. Data representing that concentration of each component in process solution which changes with passage of time are previously stored in the CPU. The CPU controls the adjusting valves on the basis of the data to supply component solutions into the process vessel so as to meet any change in the concentration of each component in process solution in the process vessel. The concentration of each component in process solution can be thus kept to be a predetermined value. This enables the wafers in every batch to be uniformly washed.
    • 一种用于处理半导体晶片的处理装置。 它包括其中包含工艺溶液的处理容器。 在工艺解决方案中,将晶片浸入并处理。 供应管从处理容器延伸到溶液储存容器。 组分溶液存储在组分溶液储存容器中并从它们提供给处理容器以保持每个组分在过程溶液中的浓度。 供应泵连接到供应管。 用于调节供应的每个部件的量的阀连接到供应管。 调节阀电连接到CPU。 表示过程解决中随时间变化的每个组件的浓度的数据预先存储在CPU中。 CPU根据数据控制调节阀,以将组件溶液供应到处理容器中,以满足处理容器中处理溶液中各组分浓度的任何变化。 因此,处理溶液中的每种组分的浓度可以保持为预定值。 这使得每批中的晶片能够被均匀地洗涤。
