Inventor: BUTLER DOUGLAS B
IPC: H01L27/108
Filed: 1991-09-27
Abstract: A trench capacitor which has a plurality of capacitor plates (38, 42) separated by a dielectric (40) within a trench (20) on a substrate (30). Both plates are located in the trench, and extend out of the trench. The capacitor has first and second portions, one depending from the other, one parallel to the side walls of the trench, the other extending laterally along the top of the substrate. A plate (38) located closest to the side wall of the trench may be a field shield layer and that is coupled to ground. The other plate (42) may be polysilicon. The other plate may be tied to a source of variable potential i.e. the data. A plurality of sacrificial layers (44, 46) are established over the structure and the structure thus formed is then patterned and etched. A pass transistor (14) is formed adjacent to the trench capacitor, and a connecting layer (72) is established connecting the second plate of the trench capacitor to the source/drain region (66) of the pass transistor. The connecting layer (72) makes electrical contact between the second capacitor plate (42) and source/drain (66) of the pass transistor and is insulated (58) from other layers in the capacitor and pass transistor.

Abstract: The invention seeks to provide a method of forming a monomolecular film of fluorine-containing molecules on a substrate surface such that the film has an uniform thickness with minimal surface irregularities and is substantially pin hole free. The invention also provides for a substrate obtained by using the same method which has excellent water-and oil-repelling, anti-fogging, and anti-contaminating properties. The monomolecular film is formed on the substrate surface either directly or via a given protective film. The monomolecular film coating is characterized by a plurality of different chlorosilane-based surface active materials which are different in molecular length have a fluorine group. The surface irregularities of the film are generally confined to the molecular level.

Abstract: A high-resolution electron microscope (1) comprising a detection system (11), an image processing system (13) and an effective electron source (3) ensuring a comparatively small thermal energy spread of the electrons to be emitted is suitable for executing a method for directly deriving amplitude and phase information of an object (17) in the form of an electron wave function q). To this end, a number of images of an object (17) are recorded by means of a high-resolution electron microscope (1) in image planes (19) with defocus values which differ only slightly. Thus, a substantially continuous series of images is formed as a function of the defocus value, resulting in a substantially three-dimensional image area. A quasi-three-dimensional Fourier transformation is performed thereon in order to separate linear and non-linear image information for the reconstruction of the electron wave function. In practice a two-dimensional Fourier transformation is applied to the recorded images which are subsequently multiplied by a complex weighting factor, followed by summing. As a result, the linear image information is concentrated on two spheres in the Fourier space, the non-linear information being uniformly distributed across the Fourier space.

Abstract: A non-intrusive method for the determination of characteristics of slug flow in a multiphase flow pipeline comprising the steps of:
     (a) detecting the acoustic emissions from the pipeline in the ultrasonic frequency range by means of at least one sound transducer, the output from which is an analogue electrical signal,   (b) converting the analogue signal to a digital signal, and   (c) analysing the digital signal to determine the characteristics of the slug flow.

Abstract: The invention makes it possible accurately to measure the position of the axis (1) of the thread of a hole by means of a three- dimensional measuring device. The method consists in inserting into the threaded hole an apparatus at the end of which are jaws (12) able elastically to move away from the axis (1) of the apparatus until stopped by the thread of the threaded hole. The apparatus is thus united with the piece (2) and its axis (1) is in coincidence with the axis (1) of the thread. A conical internal wall (14) on the inside of the jaws (12) enables these jaws (12) to be moved apart by the translational movement of the bearings (18) of a central rod (20) pressing against these internal surfaces (14). <IMAGE>

Abstract: L'invention se rapporte à une unité de commande de moteur (10) pour un moteur à induction monophase ou multiphase (51) avec boucle de commande (59a, 59b, 59c) comportant un enroulement auxiliaire (61), un condensateur (63) et un réacteur saturable (65). L'enroulement auxiliaire (61) est couplé par voie électromagnétique à l'enroulement statorique (53, 55, 57) pour que la réactance capacitive de la boucle de commande (59a, 59b, 59c) soit parallèle à la réactance de magnétisation et à la réactance de fuite rotorique du moteur (51). La boucle de commande (59a, 59b, 59c) ne comporte aucune connexion électrique directe avec le moteur (51). En faisant varier l'amplitude du courant dans l'enroulement de commande C.C (69), on peut régler l'inductance du réacteur (65) pour que la réactance capacitive de la boucle de commande (59a, 59b, 59c), telle qu'elle est réfléchie électromagnétiquement dans le moteur (51), soit en résonance avec la combinaison parallèle de la réactance de magnétisation et de la réactance de fuite du rotor. Le réglage de l'inductance du réacteur et de la réactance capacitive de la boucle de commande (59a, 59b, 59c) peut se faire pas à pas ou en continu, de façon à dépendre soit de la vitesse du moteur soit de la fréquence appliquée. L'intensité du courant du moteur est maintenue ou même réduite, quand bien même il y a augmentation du couple de sortie.

Title: Locking cap for medical implants
Inventor: MCLAREN ALEXANDER C
IPC: A61B17/68
Filed: 1991-08-22
Abstract: A locking cap for anchoring an implanted medical device within a bone (such as an intramedullary fixation rod) has a cylindrical, helically threaded body, a socket concentrically disposed in one end, and an interface for cooperating with a driving tool, such as a wrench or screwdriver. Once a device such as an intramedullary fixation rod has been implanted within a bone, the locking cap is implanted by being threaded into the bone with a driving tool, its socket engaging the near end of the device. The socket of the locking cap can be smooth, or it can be threaded so as to thread onto the near end of the device as the cap is threaded into the bone. If threaded, the pitch of the cap's outer threads can exceed the pitch of the inner threads so that the cap advances into the bone more quickly than it advances onto the end of the device. Alternatively, the inner thread pitch can exceed, or equal, the outer thread pitch so that the cap advances into the bone more slowly than, or at the same rate as, it advances onto the end of the device, respectively.
