Abstract: In a plant cutter apparatus, a handling rod includes an outer pipe portion, an inner pipe portion and three radial stay portions interconnecting the outer and inner pipe portions. The three stay portions are arranged, about an axial centerline of the rod, at non-equal angular intervals in such a manner that angles formed between the three stay portions differ from each other. Thus, the rod has a cross-sectional configuration asymmetric about the axial centerline. Geometric moment of inertia of the thus-constructed handling rod takes different values in all angular positions about the axial centerline, and thus the inherent vibrating frequency of the rod also takes different values in all the angular positions. Consequently, the rod's inherent vibrating frequency coincides with a frequency of vibrations transmitted from a drive source unit in only one of the angular positions, so that resonant vibrations of the handling rod can be avoided easily.

Abstract: A line for processing semiconductor wafers into integrated circuits (ICs) is provided with an input-output (I-O) chamber to help purge residual contamination from the wafers before they are transferred into a processing line. After a cassette containing semiconductor wafers is placed in the chamber, it is sealed from the line and from the atmosphere. Then a dry inert gas such as nitrogen is dispersed into the top of the chamber to form a covering blanket around the wafers to displace and sweep away contaminants such as air-bome particles, moisture and organic vapors. While the purge gas is flowing, gasses and residual contamination are exhausted from the bottom of the chamber at a relatively slow rate until an intermediate pressure level is reached at which pressure droplets of liquid from residual moisture and vapor can no longer condense. Then the flow of purge gas is stopped and the pressure within the chamber is relatively quickly reduced to a base operating value (e.g.

Abstract: In the dryer section of a paper machine, the paper web is pressed against the dryer cylinders by means of an air-permeable endless dryer fabric. A ventilator apparatus extends transversely across the paper machine located outside the pocket above and below the fabric turning rolls. Air from the ventilator is forced into the pocket through the fabric in the nips formed by the fabric and the fabric turning roll. This air dilutes the moisture driven from the sheet by the dryer can. The ventilator apparatus also creates a negative pressure region to exhaust air from the pocket. This exhaust air is used to scour the boundary layer of moisture laden air from the incoming fabric. The two-pass ventilator apparatus has two individual chambers separated by an induction chamber. The primary chamber contains multiple air jet nozzles. The blowing directions of the two longitudinal nozzles may be at different angles with respect to the running direction of the dryer fabric.
