Patent EP-0377872-A2 (EP)
Inventor: SCHMIDT HANS-FRIEDRICH DR-ING
IPC: G03F7/42
Filed: 1989-12-20
Abstract: A photosensitive, negative solder-resist lacquer (5), a metallic layer (6) and an etch-resist layer (7) are applied in succession to the entire surface of the circuit board, whereupon the etch-resist layer (7) is again removed in the areas directly adjacent to feedthroughs (3) and/or solder pads (4) by means of electromagnetic radiation (S), preferably by means of laser radiation. Following removal of the areas of the metallic layer (6) thereby exposed, the etch-resist layer (7), with the exception of the areas allocated to the feedthroughs (3) and/or solder pads (4), is anodically contacted and electrolytically removed so that, once the metallic layer (6) thereby exposed has been etched away, the remaining areas of the metallic layer (6) and the etch-resist layer (7) form a metallic photomask. Following exposure of the solder-resist lacquer (5), only this photomask and the underlying unexposed areas of the solder-resist lacquer (5) need to be removed. The method according to the invention is particularly suitable for the application of a solder-resist covering to three-dimensional circuit boards, since conventional masking techniques for the protection of the solder-resist lacquer cannot be applied here. <IMAGE>

IPC: D01G9/04
Filed: 1989-12-27
Abstract: Die Maschine besitzt eine liegende, rotierende, mit Schlagstiften (3) besetzte Walze (1), unter deren Unterseite Stabroste angeordnet sind. Ein die Textilfasern in Flockenform transportierender Förderluftstrom wird durch einen Einlass (6) zugeführt, der bei einem Ende der Walze (1) über deren Oberseite angeordnet ist. Ein Auslass (7) für die die Fasern transportierende Luft ist beim anderen Ende der Walze (1) über deren Oberseite angeordnet. Zwischen dem Einlass (6) und dem Auslass (7) liegen über der Oberseite der Walze (1) mindestens drei, vorzugsweise fünf, Ueberleitkammern (14, 15, 16, 17, 18), die den um die Walzenachse (A) drehenden Luftstrom je etwa um ihre eigene axiale Breite (b) in Achsrichtung weiterleiten. Die Ueberleitkammern (14, 15, 16, 17, 18) sind von mindestens vier, vorzugsweise sechs, zur Walzenachse (A) schräg gestellten Leitplatten (8, 9, 10, 11, 12, 13) begrenzt. Dadurch, dass die Anzahl der Ueberleitkammern (14, 15, 16, 17, 18) bei vorgegebenem Steigungswinkel (α) und Kammerbreite (b) grösser ist als in bekannten Reinigungsmaschinen, werden Ansammlungen von grösseren Fasermengen und Faserklumpenbildungen in den Ueberleitkammern weitgehend vermieden.

Abstract: A multimode scrambling system for video signal transmission systems is described. The system provides for baseband video scrambling controlled by a central originating computer facility. The scrambling of each field of a video changes on a per field basis. The video signal is scrambled in several modes including vertical interval scrambling, alternate line inversion, bogus sync pulse generation, video compression and video offset techniques. A scrambling sequence is sent by a unique algorithm, sent during the vertical interval to each system decoder. The algorithm is reordered for each of a plurality of fields of the video signal and the reordering position is identified by a unique synchronization pulse transmitted during the vertical interval of the video signal. Additional security measures are provided to inhibit a subscriber from avoiding a transmitted disable command, or an attempt to invade the subscriber decoder mechanical packaging security.

Abstract: A region of the surface of the semiconductor (17) is illuminated with an intensity modulated beam of light (33,38), the wavelength of the light being shorter than that corresponding to the energy gap of the semiconductor (17). The surface photovoltage (SPV) induced in the semiconductor (17) is measured under bias voltage conditions (39). The intensity of the light beam and the frequency of modulation (38) are selected such that the surface photovoltage (SPV) is directly proportional to the intensity and reciprocally proportional to the frequency of modulation. Using the surface photovoltage (SPV) and the bias voltage (Vg) measurements, the charge induced in the semiconductor space charge region (Q sc ) and the charge induced in the semiconductor (Q ind ) are determined. This information is used to determine various parameters of the semiconductor (17) including surface state density and oxide/ insulator charge. The apparatus includes a reference electrode assembly (23) which in one embodiment includes a button of insulating elastomeric material and attached to a rigid plate of insulating material. A film (25) of insulating material having the reference electrode (23) at one face is pressed against the specimen with pressure sufficient to hold the reference electrode (23) in close compliance with the specimen (15), with pressure being applied from a backing contact (31). The ac photovoltage signal is capacitively picked up by reference electrode (23) and supplied through an amplifier (41) to a phase sensitive detector (43), the output of which is coupled through an A-D converter (45) to a computer (47).

Abstract: In a computer graphic apparatus or the like, to approximate a polygonal line of a plurality of line segments (L₁ , L₂ ...) to a curve (X), the curve is divided into two curve portions (P₀₁P₁₁ , P₁₁P₀₂) at a division point (P₁₁). An error (e) between a line segment ( P₀₁P₀₂ ) linking the start and end points (P₀₁ , P₀₂) of the curve and the division point is compared with a predetermined value (V th ). When the error is small, the line segment is treated as one part of the polygonal line, but in another case, the above-mentioned process is repeated.

Abstract: Rows of wood fillets (41) are assembled into panels by step-wise advancing the rows through two stages of wedge-shaped heating and gluing blocks (51) where the edges of the fillets are pre-heated and then coated with a hot melt adhesive before being brought together with a strip of polyethylene foam (83) between the edges of the fillets. The first stage (15) assembles selacted groups of the rows and the second stage (16) joins the several groups so that the entire assemblage is accomplished over a relatively short distance and time. The resultant assembly exhibits improved flexibility and cohesiveness.

Abstract: A reaction with distillation structure (11) comprising a plurality of distillation trays (12) and interconnecting catalyst containers (18, 118) which provide a catalytic reaction zone (32) and a primary flow path for descending liquid streams. Catalytic reaction of the liquid streams within the catalyst reaction zone (32) formed in the containers (18, 118) occurs concurrently with fractionation of the reaction products on the distillation trays (12). The containers (18, 118) preferably extend continuously through the reaction zone of the distillation reactor (11) to allow for dump loading and removal of the solid particulate catalyst (20). Structure (144, 146) may also be provided within the containers (18, 118) to influence system hydraulics through the accumulation of liquid within the catalyst bed (32). This is done by providing an open area (147) interiorly of the catalyst bed (32) into which liquid on the distillation and fractionation tray (12) is radially driven. This open area (147) communicates with a liquid accumulation zone (149) wherein liquid accumulates until a sufficient liquid head drives the liquid radially outward for further contact with the catalyst bed (32).
