Patent EP-0430593-A2 (EP)
Inventor: DRAKE DONALD J
IPC: B41J2/05
Filed: 1990-11-22
Abstract: At least one through opening of predetermined location and dimensions is fabricated in a (100) silicon wafer (30) by orientation dependent etching method after completion of integrated circuits (33) on the wafer, the opening extending through the wafer between a circuit surface (31) of the wafer and an opposite parallel base surface (32) of the wafer and having a predetermined location relative to the integrated circuit on the circuit surface of the wafer. The method includes the steps of fabricating the integrated circuit on the circuit surface of the wafer; applying an etch resistant layer (34) of plasma silicon nitride on the circuit and base surfaces of the wafer; patterning the etch resistant plasma silicon nitride layer on the circuit surface to define an upper etch opening (35) having a location and dimensions which define the predetermined location and dimensions of the through opening; and patterning the plasma silicon nitride layer on the base surface to produce a lower etch opening (36) aligned with the upper etch opening within a predetermined tolerance. The wafer is then anisotropically etched to produce a first recess (37) corresponding to the upper etch opening in the circuit surface and a second recess (38) corresponding to the lower etch opening in the base surface, each of the first and second recesses being bounded by (111) plane side walls. The anisotropic etching of the second recess intersects the first recess to form the through opening bounded by (111) plane side walls and has its predetermined dimensions and location defined by the patterning of the upper etch opening.

Abstract: An artificial neural function circuit includes an organic thin film element (1 to 9) the resistance state of which changes in dependence on an electrical signal inputted thereto and exhibits information processing function similar to that of the nervous system. The organic thin film element has such physical properties that the changed resistance state is held as it is at least for a predetermined time period even after removal of the electric input signal and that the direction in which the resistance is increased or decreased depends on the polarity of the electric input signal. As an example of such organic thin film, a lead phthalocyanine thin film is employed.

Abstract: Heat exchangers of high performance and high hygiene levels are produced from steel and galvanised. It has been found that a more stable and resistant structure is achieved by constructing the heat-transferring ribs by means not of plates, but of sheets 19 to 21, 23 to 25 arranged in a multiplicity of rows. The alternating use of sheets of different width permits different dividing spacings of the sheets to be achieved in the direction of passage of the air to be cooled, without the need arising for a corresponding number of gaps acting as balancing zones. Due to the elimination or substantial reduction of the number of gaps, the latter can be held so wide without essential impairment of the thermal performance that metal bridges are avoided in the case of galvanisation and the settling of foreign bodies which impair hygiene is suppressed during operation. <IMAGE>

Abstract: An arrangement is to be created which is capable of synchronising the carrier of the receiver oscillator with the carrier of the received QAM signal in the case of a high initial frequency error. An area decision circuit (22) in the QAM receiver divides the plane of the complex received QAM signal values into active areas and passive areas, a phase correction signal being generated for the receiver oscillator (17) when a received QAM signal value arrives in one of the active areas. There are right-hand active areas (R1, R2, R3, R4) which produce a phase correction signal which results in a clockwise rotation of the phase of the carrier oscillator and there are left-hand active areas (L1, L2, L3, L4) which produce a phase correction signal which results in a counterclockwise rotation of the carrier phase of the receiver oscillator. The active areas are arranged in such a manner and have such a shape that the phase correction signal initiated by them reliably corrects the carrier of the receiver oscillator to the carrier of the received QAM signal. <IMAGE>
