Title: Optical fiber coupling member, method of producing the same and method of connecting optical fibers
Inventor: WATANABE TSUTOMU
IPC: G02B6/38
Filed: 1996-06-20
Abstract: The present invention provides a connecting member for facilitating connecting of optical fibers, and a connecting method in which the loss due to connecting is small.   An optical fiber connecting member is composed of: a retaining portion having  through-holes  each  of  which  has  an  inner diameter slightly larger than the outer diameter of optical fibers to be connected; and introduction portions which are integrally formed with and on the opposite end sides of the retaining portion and each of which has introduction grooves communicated with the through-holes to thereby make it easy to insert ends of the optical fibers into the through-holes.          Further, the inner diameter of each of the through-holes is reduced by heating the connecting member to thereby make axis alignment  of  the  optical  fibers  automatically  to  obtain connecting in which the connecting loss is reduced.

Title: Method for excitation and detection of magnetic elements
Inventor: TYREN CARL
IPC: G06K19/06
Filed: 1995-04-25
Abstract: A method for excitation and detection of magnetic resonance elements (10) in an interrogation zone (11), whereby a magnetic excitation signal is generated by at least one excitation means (12) and is supplied to the resonance element, so as to force the resonance element (10) into mechanical self-oscillation, and whereby a magnetical signal caused by the self-oscillation is detected. The excitation signal is generated by at least two excitation means (12) being located at a distance from each other, whereby a symmetry plane (14) for the excitation signal is obtained between the excitation means (12). The magnetic signal caused by the self-oscillation is symmetrically recorded at both sides of the symmetry plane (14), and the resonance elements are placed between an excitation means (12) and the symmetry plane (14), the recorded signal thereby containing the magnetic signal caused by the self-oscillation, but lacking the excitation signal.

Title: Method for Wireless Communication System Planning
Inventor: TANG YUGIANG
IPC: H01Q1/24
Filed: 1996-01-29
Abstract: A method for wireless communication system planning includes, in a first embodiment, determining an image tree (500), based on a transmitter location (401) and the reflective (415) and diffractive (425) surfaces within a coverage region, and limiting the image tree to exclude branching for higher order im-ages requiring more than a predetermined number of reflections and/or diffractions, or potential child im-ages corresponding to surfaces not within the scope of the parent image (530, 560). Based on the im-age tree and propagation path back-tracing (620), a received signal quality measure (e.g., power) is de-termined for each receive location. By comparing the different received signal powers, an optimal receiver unit location is determined. Further, by building fur-ther image trees for further transmitter locations, an overall coverage quality can be determined for each transmitter and compared to yield an optimal trans-mitter location.

Abstract: An image acquisition unit provides true color high resolution digital images of the retina of the eye to a computer network (14, 16, 18) which interfaces with a central library and displays images at a remote work station (20A and 20B) for diagnostic examination. The computer network (14, 16, 18) is also interfaced with a unit for entering medical history information, and the diagnostic data, stereo images and medical records are linked in a relational databse allowing all text and image records of the patient to reside on a work station/display (20A and 20B) for review or consultation. A telecommunications link (22) interconnects the computer network (14, 16, 18) and image examination stations with the image acquisition station where the patient is actually examined, so that stereo fundus images may be made available through the computer without degradation for viewing on the examination displays remotely from the room, building, or city where the images are acquired from the patient. By introducing digital true-color normalization at the image acquisition source (34, 32), applicant avoids the problem of spurious color artifacts arising when the images are viewed subsequenty, or on other monitors.

Inventor: GLEZER BORIS
IPC: F02C7/28
Filed: 1997-07-15
Abstract: Past gas turbine engines have been manufactured with a variety of systems which have attempted to compensate for the varying radial clearance or interface between a tip of a turbine blade and a surrounding shroud.  Such systems have engineered in large clearances, utilized special tips on blades and provided abradable structures.  The present system controls a radial clearance or an interface or spaced distance between a tip of a blade and a stationary shroud.  The system includes an introduction of a cool fluid or a hot fluid flow or a combination of cool fluid and hot fluid into a support case cavity.  The flow is controlled by modulating a flow control apparatus and controlling the expansion of a nozzle support case and a stationary shroud relative to the position of the tip of the turbine blade.  The system improves efficiency, longevity and operation of the gas turbine engine.

Abstract: Sulfur species present in cracked naphtha (1) are converted and removed by firstpassing the naphtha (1) over an acid catalyst in an alkylation reactor (4) to alkylate the thiophenic compounds in the naphtha using the olefins, i.e., monoolefins anddiolefins, present in the naphtha (1) as alkylating agent. Alkylated thiophenes are concentrated in the heavy portion of the naphtha (8) by distillation, reducing the amount of naphtha that needs to by hydrodesulfurized in the reactor (10). Olefins in cracked naphtha are concentrated in the light portion of the naphtha (7) which is not subsequently hydrotreated. Thus, octane and hydrogen consumption penalties associated with hydrotreating are minimized.
