Patent number: 7531039Abstract: Of a substrate-facing surface 24 of an atmosphere blocking member 2, a central area 241 which is faced with an approximately central portion of a substrate S is a flat surface while a periphery edge area 242 which is faced with a periphery edge of the substrate S is an angled surface which becomes closer to the substrate S with a distance toward a periphery edge of the substrate-facing surface 24. Hence, a micro-space SP between the substrate S and the atmosphere blocking member 2 becomes gradually narrower in a direction R which is toward the periphery edge of the substrate S. As an atmosphere gas is fed into the micro-space SP, the atmosphere gas is compressed in the vicinity of a periphery edge of the micro-space SP and a pressure rises. As a result, the micro-space SP becomes positively pressurized as compared with a mist-splashed atmosphere, which effectively prevents a mist from invading other major surface S2 of the substrate S.Type: GrantFiled: September 24, 2003Date of Patent: May 12, 2009Assignee: Dainippon Screen Mfg.

Patent number: 7153364Abstract: The present invention provides a system and methodology for dummy-dispensing resist though a dispense head while mitigating waste associated with the dummy-dispense process. The dummy dispensed resist is returned to a reservoir from which it was taken. Between substrate applications, the dispense head can be positioned to dispense resist into a return line. The flow of resist from the dispense head keeps resist from drying at the dispense head. By funneling the dummy-dispensed resist into a return line with low volume, for example, waste from the dummy-dispensing process can be mitigated.Type: GrantFiled: October 23, 2001Date of Patent: December 26, 2006Assignee: Advance Micro Devices, Inc.Inventors: Bharath Rangarajan, Ramkumar Subramanian, Khoi A.

Patent number: 7143464Abstract: When vehicle wheels are powder-coated with powder coating, those surfaces on which no coating is wanted are always also coated. To suck off the powder coating from these surface areas before it is baked in, a device which includes a conveyor system, an electronic camera and a suction station is used. The electronic camera records the axial and angular position of the vehicle wheels which pass it, and supplies corresponding data to a controller. After a certain time delay, this causes a suction head in the suction station to move, in such a way that it approaches the vehicle wheel with appropriate alignment of its axis and angular position, and using suction nozzles sucks off those surfaces of the vehicle wheel on which the powder coating is not wanted. During the suction process, the suction head moves together with the vehicle wheel, at the same speed.Type: GrantFiled: October 21, 2003Date of Patent: December 5, 2006Assignee: Eisenmann Maschinenbau KGInventor: Jürgen Brosi
