Abstract: A plasma processing apparatus comprises a reaction chamber, an upper electrode, a lower electrode which confronts the upper electrode and also functions as a sample stage, means of supplying RF power between the upper electrode and lower electrode such that the RF power is supplied to one of the upper and lower electrodes, with another electrode and the reaction chamber being grounded, and RF impedance matching means, wherein the capacitance between the grounded electrode and the reaction chamber is 125 pF or less. The apparatus is capable of stabilizing the plasma generation and alleviating the occurrence of sudden deterioration of the repeatability of plasma processing and unequal performance of plasma processing among individual apparatus. The apparatus can be applied suitably to etching apparatus having small electrode spacing and using a chlorine compound gas or a bromine compound gas such as Cl.sub.2 or HBr.

Abstract: An add-on telephony server platform provides inter alia high-speed call switching. The outbound automatic call distributor establishes one "nailed" voice connection between the telephony served platform and trunks connected to the automatic call distributor. The outbound call distributor establishes another "nailed" voice connection between the telephony server platform and the voice sets at the agent stations assigned to outbound operations.

Abstract: A multi-element, H plane, phased, dipole array antenna has a high gain over a wide angle in azimuth and over a controlled sector in elevation. Two printed wiring boards feed and physically support the dipole antenna elements. The phase and spacing of the dipole elements establish the radiation elevation angle, and a planar metallic reflector, spaced on the order of a half wavelength of the RF signal from the dipole array, interacts with the dipole-element pattern, to provide the wide angle azimuth gain.

Abstract: In a simulated synthetic aperture radar SAR, a terrain elevation model is provided. A phase component of the simulated SAR data is computed by determining a distance between incremental terrain points and a simulated SAR platform modulo the wavelength. The amplitude component is computed in the following manner. The terrain elevation model is rotated about a vertical axis to present terrain strips extending perpendicular to the assumed direction of travel of the SAR platform. Points distributed along the terrain strips are projected into an illumination plane perpendicular to the assumed SAR signal and into an image plane perpendicular to the illumination plane.

Abstract: Thin sheets on which a product is held by limited adhesion are transferred from a first conveyor onto a speedup conveyor which slides the sheets, one by one, onto a pair of intermittently rotatable paddles. The paddles comprise a lattice of low-friction material and define receiving surfaces angled toward one another along a direction in which the sheets slide. The paddles rotate 1/2 revolution in response to the leading sheet on the speedup conveyor passing a photocell and form a stack in a compartment on an intermittently moving conveyor below. When a predetermined count of sheets is in the stack, the intermittently moving conveyor is advanced to move an empty compartment under the paddles.

Abstract: The invention discloses a pedal mechanism for a bicycle or a piece of exercise equipment which allows one to impart forward motion to the drive wheel of the bicycle through an alternating or stair climbing pedalling motion. The downward force of one of the pedals causes the other pedal to move in the opposite direction. Depending on the position of the pedals, many different pedalling patterns are possible.
