Title: Procedure for drying silicon
Inventor: HERRMANNSDORFER DIETER
IPC: H01L21/306
Filed: 1996-08-09
Abstract: The invention relates to a procedure applicable for drying substrate surfaces of a large number of materials, such as semiconductors, metals, plastics and, in particular, silicon. The silicon (1) is dipped into a liquid bath (2) and the silicon (1) is separated from the liquid (3), the liquid of the bath (2) consisting of an aqueous HF solution (3) with a concentration between .001 and 50 %.

IPC: G01R33/28
Filed: 1997-01-21
Abstract: Apparatus and method for monitoring a system in which a fluid flows and which is characterized by a change in the system with time in space. A preselected place in the system is monitored (14) to collect data at two or more time points (12) correlated to a system event. The data is indicative of a system parameter that varies with time as a function of at least two variables related to system wash-in and wash-out behaviour (15). A calibration map is made (20) on a calculated basis with each pixel or voxel representative of a color hue indicative of wash-out behaviour (19) and a color intensity indicative of wash-in behaviour (16). When a satisfactory map is obtained, the collected data is processed on the basis of the map to obtain an image of the preselected place with each spatial unit thereof correlated with a color hue and a color intensity. Software and a data processing system are provided to develop the calibration map. The calibration map and image of the preselected place are also novel implementations.

Filed: 1998-08-26
Abstract: A nozzle arrangement for a scrubber, especially for flue gas desulfurization, which scrubber has a distributor for scrubbing liquid with branch pipes extending therefrom and nozzles connected to the branch pipes. The nozzles are positioned in accordance with the following:          (a) liquid concentrations of a component to be absorbed from a gas stream scrubbed in the column are measured above a plane of the nozzle assembly at N locations of a grid of equal area elements of a cross section of the column;          (b) the N concentration values are compared with a predetermined value;          (c) upon deviation of a measured concentration value from the predetermined value, a position of at least one of the nozzles is varied by selection of a length and location of an intermediate pipe section connecting the one of the nozzles to a respective branch pipe laterally thereon; and (d) repeating (a) through (c) until the concentration values measured above the plane are approximately equal except for at a wall region of the column. The resulting nozzle arrangement substantially ensures uniform scrubbing of the gas stream so that regions of low scrubbing effectiveness are avoided.

Title: Modular agricultural implement control system
Inventor: JACOBSON ERIC D
IPC: A01C7/08
Filed: 1998-09-22
Abstract: A control system for agricultural implements such as planters, conventional or air drills is disclosed herein. The implement includes a frame with one or more sections. Each section supports a plurality of row units configured to apply a product at variable rates to rows in a field. The products can include seeds, fertilizers, insecticides and herbicides. In one configuration, the control system monitors the rates at which the product is applied to the rows. This configuration of the control system includes sensors configured to sense the rates at which product is applied, and a control module configured to monitor the sensed rates and generate a multiplexed output signal representative thereof. The output signal is used, for example, by a cab-mounted display or recording device. The control system, however, can be reconfigured to both monitor and control the application rates by installing a second control module on the frame. The second control module generates rate control signals in response to rate command input signals. The rate control signals are applied to the metering device to cause the metering device to meter product to the row units at the commanded rates. Commanded rates are set, for example, by a cab-mounted display control module.
