Patent number: 5911232Abstract: Disclosed is an ultrasonic cleaning device including a cleaning tank containing a semiconductor wafer W and pure water, and a plurality of vibrating plates provided with the cleaning tank. The vibrating plates are electric distortion transducers. By controlling the output phases of oscillators that vibrate the plates with a single oscillating source, the output phases of the oscillation sources can be matched. This enables uniform sound pressure distribution. Consequently, ultrasonic interference between vibrating plates can be eliminated. Uniform sound pressure distribution makes it possible to obtain a uniform particle removal rate, thereby improving cleaning efficiency.Type: GrantFiled: August 29, 1997Date of Patent: June 15, 1999Assignee: Tokyo Electron, Ltd.Inventors: Shori Mokuo, Keiji Taguchi, Shigenori Kitahara

Patent number: 5902485Abstract: An access valve suitable for controlling fluid flow into and out of a chromatography column has relatively movable valve elements preferably represented by a central axially movable probe with a head acting as a spool valve in a barrel. Axial movement of the probe adjusts the valve between a fully open condition, in which both a first conduit extending through the probe and a second conduit defined around the probe are open to the column interior, and a partly open condition in which a sealing component of the probe closes the second conduit. Also, further axial movement of the probe provides a fully closed position in which both conduits are closed. The partly open position is useful for packing chromatography media into its column while the third position is useful for unpacking the same. In the closed condition of the valve, the first and second conduits communicate with one another so that the valve interior can be cleaned while the column is operating.Type: GrantFiled: March 26, 1997Date of Patent: May 11, 1999Assignee: Amersham Pharmacia Biotech ABInventors: John Davis, Martin John Hofmann
