  • Patent number: 5911232
    Abstract: 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.

  • Patent number: 5902485
    Abstract: 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.

  • Patent number: 5894836
    Abstract: A compound solar water heating and dehumidifying device including an adsorption bed disposed at a lower rim of a plate type heat collector of a solar water heating element for causing a heat collector element to absorb heat in the day-time and the adsorption bed to regenerate and accumulate heat. At night, the heat of adsorption and heat of condensation are released to the heat collector element to retard the drop of temperature of water in water channels that are in contact with the heat collector element. Therefore, dissipation of heat from the hot water in a water tank may be retarded and water moisture may be removed.

  • Patent number: 5893741
    Abstract: A method for formation of both local innerconnection and silicidation of source/drain transistors using the deposition of a blanket silicon layer over the entire top surface of the transistors and selectively stripping of unwanted portions of the silicon layer is disclosed. The method includes the step of applying a photoresist mask to map out where the local interconnection and source/drain are to be located. The final recited step is to deposit a thin metal layer to provide for the silicidation to complete the transistor. The silicon layer that is deposited has a thickness of 20 to 300 millimeters, and the thin metal layer is either cobalt or titanium having a thickness of 10 millimeters to 100 millimeters.
