  • Patent number: 5920253
    Abstract: A local area network arrangement is taught for implementing a control system. The local area network arrangement includes a low-voltage bus composed of a cable pair, functioning as a common transmission path of the network, a plurality of connection units connecting the bus to operating devices to be controlled by the network, and a control unit common to the operating devices, connected to the bus, for controlling the operating devices. Data is transmitted in the network both from the control unit to the connection units, and from the connection units to the control unit. More particularly, the control units send to the bus a constant-frequency carrier signal whereby a number of cycles of the carrier signal form a transmission frame, in which each connection unit corresponds to a particular cycle of the frame.

  • Patent number: 5916128
    Abstract: A canister, especially for two-cycle engines, having both noise reduction and pollutant treatment attributes in a single unit. To effectuate sound reduction the canister muffler has mounted within it several tubes randomly arranged in relation to one another. Thus, an emission stream is forced to frequently change directions, causing a baffling effect and a reduction in noise. Further, these tubes are coated with a catalytic substance to treat the emission stream and thus decrease undesired pollutants. The turbulent flow of the emission stream caused by the tubes also serves to increase the contact with the catalyst. Hence, a single canister is all that is necessary to both silence and treat the emission exhaust stream.

  • 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.
