Patent EP-0311612-B1 (EP)
IPC: G01L7/08
Filed: 1987-05-29
Granted: 1993-03-24
Abstract: A capacitive pressure sensor (47, 75, 100, 130, 170, 190) that is fabricated in a batch process affords isolation for the sensing element (12, 102, 134, 183) and leads from the pressure media and provides stress isolation as well. The pressure sensor (47, 75, 100, 130, 170, 190) is made up of a sandwich construction including a silicon wafer (10) which is etched from one side to make cavities (14) in a plurality of desired locations to form deflecting diaphragms (12, 102, 134, 183), one surface of which acts as a capacitor plate. A glass layer (20) is metallized on both sides and has holes drilled in locations that align with the diaphragms formed on the silicon wafer (10). The glass layer (20) is anodically bonded to the wafer to form capacitance gap of a few microns relative to the one surface of each diaphragm (12, 102, 134, 183). The assembly of the metallized glass layer (20) and the silicon wafer (10) is in a preferred form sandwiched between two additional layers (30, 42, 154, 161, 163), and bonded together in a vacuum atmosphere. The four layer sandwich is then cut up into individual sensors (47, 75, 100, 130, 170, 190). The initial assembly can be formed to provide dampening of the diaphragm response times and to minimize the likelihood of false signals at high frequency inputs.

Title: Exciting or feeding system for a parabolic antenna
IPC: H01Q21/24
Filed: 1988-11-18
Granted: 1993-08-25
Abstract: In order to be able to receive and transmit differently polarised electromagnetic waves with only one supply system, two polarisers are arranged in a waveguide emitter, both of which must be capable of being brought into any required angular positions with respect to one another. This demands high structural complexity and relatively extensive adjusting measures. In order to produce an excitation and supply system which is of much simpler construction and which can be adjusted very much more easily, a 90 DEG  phase-shifting component (15) is arranged in a waveguide (5) in the receive direction and a 180 DEG  phase-shifting component (17) is arranged downstream from it. The 90 DEG  phase-shifting component (15) is installed in a fixed manner such that it cannot rotate vertically or horizontally. Only the 180 DEG  phase-shifting component (17) has to be rotated into a specific angular position to receive one of the four differently polarised waves. The excitation and supply system is primarily suitable for the reception of television broadcasting satellites. <IMAGE>

A reduced pressure in the fluid collection head pulls fluid through the porous support. The system is automated by providing a guide channel for holding a plurality of covers in correct orientation and a magazine for holding a stack of covers. An indexing arm delivers the bottom-most cover in the stack to the guide channel and urges covers in the channel along its length. The system includes reciprocating means to bring the dispensing assembly and fluid collection head to the cover for coating and away from the cover after coating. The dispensing assembly may include a template for coating the reagent in a distinct pattern. The system can include a plurality of coating stations to permit coating with a plurality of reagents.
