Patent EP-0218241-A2 (EP)
Inventor: FAROUDJA YVES C
IPC: H03H17/02
Filed: 1986-10-08
Abstract: A multi-dimensional comb filter system for processing e.g. a quadrature modulated color television signal includes an input for receiving the signal; a first comb filter operating at the first period (such as the picture frame rate); and, a second comb filter operating at the second period (such as the picture line rate) connected in tandem with the first comb filter. A delay matching network is connected to the input and provides a delay to the original signal corresponding to the sum of the first period and the second period. A linear adder circuit is connected to the second comb filter ans to the delay matching network for combining in phase the delayed signal passing through the delay matching network and the signal put out by the second comb filter. The adder circuit includes an output for putting out the signal which has been separated by multi-dimensional comb filtering of the original signal without any process adaptivity or switching in response to the content of the original signal.

Abstract: The method comprises the following steps: 
providing a substrate (3) having an underlying metalliza­tion (4) therein; placing an insulator (5, 6, 8) on said substrate (3); selectively removing first portions of said insulator at first locations, said first portions partially penetrating through said insulator; selectively removing second portions of said insulator at second locations, said second por­tions penetrating fully through the remainder of said insulator; said second portions being in alignment with some of said first portions; simultaneously depositing metal (9) over said insulator to form said overlying metallization in said first locations and said stud via connections in said second locations, and removing any of said metal (9) which overlies said insulator at locations other than said first locations. The method is applied for forming simultaneously an overlying metallization pattern and stud via connections to an underlying metallization.

Abstract: A system for the controlled-rate release of active substances, consisting of:
     a) a deposit-core comprising the active substance and having defined geometric form;   b) a support-platform applied to said deposit-core.   
     Said deposit-core contains, mixed with the active substance, a polymeric material having a high degree of swelling on contact with water or aqueous liquids, a gellable polymeric material, said polymeric materials being replaceable by a single polymeric material having both swelling and gelling properties, and other adjuvants able to provide the mixture with suitable characteristics for its compression and for its intake of water. 
     Said support-platform consists of a polymeric material insoluble in aqueous liquids and partially coating said deposit-core. 
     The intensity and duration of the swelling force of said polymeric material with a high degree of swelling constitutes the primary factor in controlling the release of the active substance.

Abstract: A fasciated yarn suitable for making apparel fabric and having properties approaching that of ring spun yarn is produced by vacuum spinning, including directly from sliver. An elongate hollow shaft (20) of the vacuum spinning apparatus has a vacuum reservoir (32), or interior chamber, that is generally in the shape of a right circular cone, and the interior passageway (31) of the shaft from the first end (21) thereof to the interior chamber can have the form of a right circular cone frustum. Perforations (40) operatively connected to the interior chamber have a generally wedge-shape. The perforations and the passageway sections between the first end of the shaft and the perforations are dimensioned so that they allow sufficient air flow to achieve optimum fiber wrapping action.

Abstract: Parallel bars, in which two cable devices (5) are provided laterally, a balancing device (10) being provided between one end of one of the cable devices (5) and the floor (3). It is desirable for the number of devices to be actuated for a change in the bar spacing to be reduced considerably. This is achieved in that the balancing device is a tensile spring device (10) with a compression spring element (12) having a progressive spring characteristic. The progressive spring characteristic normally given in a compression spring element does not prove to be a hindrance since the gymnasts generally require an increasing bracing force as the bar spacing increases. <IMAGE>

Abstract: The present invention relates to a system for producing image signals for photographing an image of a subject by means of a solid state image sensing device or the like and for producing a brightness signal and line sequential color difference signals from the image signal. According to the present invention, the image of the subject is image-sensed by means of the image sensing device formed with a color filter wherein a first horizontal scanning line arranged therein with filter elements opposed to an image sensing plane, for separably transmitting at least red light and green light and a second horizontal scanning line arranged therein with filter elements opposed to the image sensing plane, for separable transmitting at least blue light and green light are alternately arranged, to thereby obtain image signals. The image signal thus obtained is signal-processed to produce the line sequential color difference signals R - Y and B - Y. With this signal-processing, the system can produce the image signals including the line sequential color difference signals with a simplified arrangement without imparring the color productivity.

Abstract: The following is a description of an electronic method used for correcting telescope images, allowing the use of different ca­toptric elements, based on inflation and other systems, having big size, being light though not very accurate, which can as well be mounted on telescopes orbiting around the earth. 
     We therefore suggest the use of not completly accurate reflec­tors which nonetheless have a wide reflecting surface, suitable for increasing the quantity of received light without affecting image resolution, in addition to the installation of both a laser device and a programmed electronic processor which recti­fies image errors caused by curvature defects typical of giant mirrors. Instead of being made of solid material and having a short diameter, the primary mirror can be made of thin sheets of partiallly elastic material, reflecting from one face only, and kept in parabolic or spherical shape by gas pressure or vacuum while being stretched on suitable gasproof containers. Pressure or vacuum values are kept constant, or anyway adequate to the functions and operations performed by the telescope, by a pump driven by sensors connected to an electronic processor programmed in line with the varying conditions of the setting where the telescope is located. 
     This way, the optical train can be disassembled into smaller parts which can be assembled again, allowing a double use of the telescope, both on earth and in space. The image electronic correcting system to be used on giant reflectors presents an additional advantage because in general, the optical performance of telescopes is improved whenever said system is applied on amateur and on-the market standard telescopes as well.

Abstract: The present invention relates to a method of making a tape suitable for impregnation into a porous metal matrix which generally comprises the steps mixing a liquid dispersion of PTFE with a coagulant to form a paste, placing the paste between a layer of supporting material (38) and a layer of filter paper (40) to form a sandwich, compressing the sandwich, transferring the sandwich to a gauze-like material (50) so that the filter paper layer of the sandwich is adjacent the gauze-like material, applying a vacuum (54) to the gauze-like material and adjacent filter paper layer to remove some excess liquid from the paste, and removing the layer of filter paper from the sandwich to leave a tape (58) comprising PTFE and liquid and a layer of supporting material adjacent the tape. The method of the present invention may be used to apply, by impregnation, a PTFE based composition (16), which may include various fillers (24,26,28) therein, to a porous metal matrix or interlayer (14). In addition, some of the PTFE based composition may be left above the porous metal interlayer after the impregnation step. After sintering, a composite bearing material which may include a metal backing, a porous metal interlayer on the metal backing, and having the PTFE based composition substantially filling the pores of the porous metal interlayer and forming a surface layer on the bearing material may thereby be produced.
