  • Patent number: 10576492
    Abstract: A surface treating apparatus that suppresses occurrence of defects is provided. A treatment solution is accumulated in a tank 15 through a treatment solution collecting port/air discharging port 13 in a lower portion of a body 4. An air heated by the treatment solution flows toward an upper portion (portion without the treatment solution) of the tank 15 via the treatment solution collecting port/air discharging port 13 in the lower portion of the body 4, and is discharged via an exhaust duct 17. In this way, the air that is heated and tends to flow upward in the body 4 is discharged from the lower portion thereof and is replaced with an external air from the upper portion thereof. Accordingly, the air in the body 4 can be maintained at a uniform temperature. Thus, the treatment solution that reaches a lower portion of a substrate 54 from an upper portion thereof can be maintained at a uniform temperature.

  • Patent number: 5243264
    Abstract: A tool fastening apparatus for industrial robots comprises a coupling unit attached to the arm of a robot and a coupling unit attached to a tool to be used with the robot. When the two coupling units are joined together, their relative position can be easily and accurately fixed by means of positioning couplings comprising ball rings carrying a set of annularly arranged balls slightly sticking out from the plane of contact between the two coupling units. Accurate positioning is achieved by bringing the balls on the two ball rings into engagement, which, in turn, is achieved by fitting each ball on one ball ring into between two adjoining balls on the other ball ring.
