Title: Method of manufacturing multi-level contacts by sizing of contact sizes in integrated circuits
Inventor: HELLIG KAY
IPC: H01L23/522
Filed: 2003-12-30
Abstract: A method [600] for forming an integrated circuit includes etching a first opening [228] [338] [402] to a first depth in a dielectric material [322] over a semiconductor device [317] on a first semiconductor substrate [202] and etching a second opening [230] [340] [404] to a second depth in the dielectric material [322] over the first semiconductor substrate [202]. The first and second openings [228] [338] [402] [230] [340] [404] are differently sized to respectively etch to the first and second depths in about the same time due to etch lag. The first and second openings [228] [338] [402] [230] [340] [404] are filled with conductive material.

Patent WO-8200630-A1 (WO)
Inventor: MEISEL T
IPC: B66C1/58
Filed: 1981-06-26
Abstract: Load skidding vehicles commonly include a grapple assembly (42) which under load conditions can pivot rearwardly about its support point (52) resulting in disproportionate loading of the rear wheels and consequently instability of the vehicle. A connecting member (62) is pivotally attached between the grapple (42) and a hydraulic cylinder (74) which is attached to the skidder (2). Operation of the hydraulic cylinder (74) causes the grapple (42) to rotate about its support pivot (52). The hydraulic cylinder (74) may be locked causing the grapple (42) to be locked in relation to the boom assembly (26). During load hauling operations this mechanism is used to lock the load in a position near the vehicle resulting in increased stability. The mechanism is also of use in positioning the grapple assembly (42) with respect to the load prior to grasping it.

IPC: G06F17/00
Filed: 1981-09-28
Abstract: A method and apparatus for determining a hemodynamic characteristic form noninvasive measurements of blood pressure (18, 160 and 165) in a human body simultaneously with measurement of a characteristic value (15, 101, 100, 105), such as impedance, a cross section of the body, and processing (20, 120) signals representative of the characteristic value in the blood pressure measurements through an electronic device (120, 130, 140) to obtain an electrical signal representing the hemodynamic characteristic. In the illustrated embodiment, means (40, 170, 175) are provided for displaying the hemodynamic characteristic, such as by means of a video display, graph, plot, or printout. In the illustrated embodiment, a plurality of the noninvasive measurements are taken over a time period, and the hemodynamic characteristic is determined and displayed responsive to the plurality of noninvasive measurements. Hemodynamic characteristics which can be determined in accordance with the teachings of the present invention include cardiac output over a time period, modulus of elasticity of the arterial walls in the body section across which measurement is being made, blood flow, cardiac output, contractility, useful power output of the heart, systemic vascular resistance, cardiac index, stroke volume, cross-sectional area of the blood vessels within the body section, and so forth. The determination can be made in absolute terms, relative terms, in terms of deviation from mean, or in terms of a range of values. The determined value can be displayed in the form of a chart, graph, curve, table, or other forms.

Abstract: Des procédés de protection des plantes contre une attaque virale consistent à faire en sorte que les plantes produisent une réponse d'interféron ancestrale au virus. La réponse peut être produite par modification génétique de la plante pour qu'elle contienne une information génétique d'interféron ancestrale analogue à celle généralement incorporée dans l'interféron humain pour que la plante produise son propre interféron, ou bien par application topique de l'interféron animal, y compris des médiateurs intracellulaires humains ou des inducteurs d'interféron tels les dsARN. Des molécules d'interféron incomplètes travailleront tant qu'un fragment contiendra une séquence d'acides aminés essentiels qui peut, indépendamment, induire la réponse d'interféron.

Abstract: Un comprimé de chlorure de potassium à libération contrôlée comprend des cristaux de chlorure de potassium ayant une ouverture des mailles comprise entre 30 et 50 mailles environ et enrobés d'un matériau d'enrobage composé d'éthylcellulose et d'hydroxypropylcellulose. Les cristaux enrobés forment des micro-grains qui peuvent alors être pressés pour fournir des comprimés. Ces comprimés se désintègrent rapidement dans un environnement aqueux, assurant ainsi une dissolution plus uniforme du composant actif par comparaison à d'autres types de formules de dosage de chlorure de potassium à libération contrôlée. La distribution des micro-grains de chlorure de potassium sur une grande surface des muqueuses gastrointestinales aide à réduire le risque de lésions gastrointestinales. La formation de micro-grains enrobés qui se dispersent rapidement en contact avec un environnement aqueux permet l'administration orale répétée et chronique d'une dose relativement élevée de chlorure de potassium (20 mEq).

Abstract: A fluid meter (10) such as a density meter or a Coriolis-type mass flow meter includes a fluid tube (14) which is mounted to allow for expansion and contraction relative to a base (12) to which opposite ends of the tube are mounted. A single, rectilinear flow tube measuring section (14c) is bounded at each end by a thermally insulating wall (24, 26) having a linear bearing (20, 22) which allows longitudinal axial movement while restraining transverse movement. Expansion and contraction of the measuring section is accommodated by a laterally coiled tube portion (14f). Other embodiments (40, 80, 200, 230) may utilize more than one flow tube measuring section, and transverse movement of the flow tube is inhibited by either linear bearings (54; 94) or node plates (204, 205, 206, 207; 246, 247, 248, 249) rigidly fixed to the flow tube measuring section. In a serial double-type flow sensor, three serial rectilinear and parallel section (44c, 44d, 44e; 201, 202, 203) of the flow tube are joined by arcuate sections (44f, 44g; 217, 218). In another embodiment, the flow is split into two parallel tubes (84a, 84b; 233, 234), one end is mounted to the base or housing (82; 232) by a compressible section (112; 270) and the other end is fixedly mounted directly to the base (82; 232).

Abstract: Un éclairage de scène à largeur du faisceau lumineux variable comprend un réflecteur axialement mobile (18) servant à modifier la largeur du faisceau lumineux. Le réflecteur comporte plusieurs ailettes s'étendant vers l'extérieur radialement et vers l'avant axialement et disposées côte à côte de façon à définir une surface de réflecteur en forme de cuvette. Une bride de support fixe (58) est placée en contact frictionnel avec la surface s'étendant radialement vers l'extérieur de chaque ailette. La base (26) du réflecteur est disposée en sandwich entre un élément de base (28) et un élément en anneau (24). Une vis mère (30) mue par un moteur est fixée à l'élément de base et sert au déplacement axial du réflecteur par rapport à la bride de support. Le réflecteur définit un premier point focal et un second point focal le long de l'axe du réflecteur. Une source lumineuse (16) est fixée au niveau du premier point focal, qui reste sensiblement fixe par rapport à l'élément de base . Le contact de la bride de support avec les ailettes du réflecteur produit une variation du diamètre des ailettes du réflecteur pendant le mouvement de l'élément de base, déplaçant ainsi le second point focal et faisant varier la largeur du faisceau lumineux sortant du réflecteur.
