Title: Balloon for a dilation catheter and method for manufacturing a balloon
Inventor: JUNG EUGENE J JR
IPC: B29C49/18
Filed: 1998-04-23
Granted: 2007-06-26
Abstract: A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.

Abstract: The combine harvester has a threshing and separating rotor with a threshing cylinder section that cooperates with a concave to thresh crop material. A hydraulic motor drives the rotor. A hydraulic pump, driven by an internal combustion engine, supplies hydraulic fluid to tile hydraulic motor to drive the rotor. An electronic controller receives a rotor speed measurement from a speed sensor and compares the rotor speed with a selected threshing and separating rotor speed selected by an operator of the harvester and stored in the electronic controller. When the rotor speed varies from the selected rotor speed, the electronic controller sends a signal to a displacement control to change the threshing and separating rotor speed to approach the selected rotor speed. The displacement control can reverse the flow of hydraulic fluid to the hydraulic motor to reverse the direction of rotor rotation.

Title: Communication terminal apparatus
Inventor: IRUBE AKIRA
IPC: H04M1/72505
Filed: 1998-03-03
Granted: 2004-06-01
Abstract: A communication terminal apparatus is separated into a housing that is capable of video/voice communications, and a housing that is capable of only voice communications. Since functions of the housing that is capable of only the voice communications are limited, the housing becomes small, can be stored in a pocket or the like, and can immediately go off-hook upon reception of an incoming call. Upon reception of a videophone communication request, the user goes off-hook using the housing that is capable of only the voice communications to immediately make voice communications with the partner terminal, and can switch the communication mode to the video/voice communications using the housing that is capable of the video/voice communications, as needed. Hence, even a communication terminal having a videophone function can comprise a video input/output function without impairing its portability and storability.

Abstract: An RF EAS tag (10) includes a substrate (12) with a conductive element (14) positioned on a face surface (18) thereof and having electrically inductive properties. A capacitive element (20) is positioned on the face surface (18) and has electrically capacitive properties wherein the inductive (14) and capacitive (20) elements are operably coupled together to form a resonant circuit which resonates when an electrical signal of a predetermined resonant frequency is applied to the tag (10). The capacitive element (20) comprises a dielectric ink (22) substance having a high dielectric constant for producing the desired resonant circuit on a single face surface of the substrate. An alternative tag (50) comprises a substrate (52) with a conductive layer positioned thereon and a gap (56) formed in the conductive layer exposing a portion of the substrate. This forms a slotline waveguide shorted at both ends. A high dielectric constant ink substance (58) is then deposited in the slot. This greatly reduces the wavelength in the waveguide allowing an RF frequency 1/2 wavelength resonant line to be made of a practical length.

Title: Stable recombinant yeasts for fermenting xylose to ethanol
Inventor: HO NANCY W Y
IPC: C12P7/06
Filed: 1997-05-06
Granted: 2012-04-17
Abstract: Described are recombinant yeast which ferment xylose to ethanol and which maintain their ability to do so when cultured for numerous generations in non-selective media. The preferred yeast contain multiple copies of integrated genes encoding xylose reductase, xylitol dehydrogenase, and xylulokinase fused to promoters which are non-glucose inhibited and which do not require xylose for induction. Also described are preferred methods for integrating multiple copies of exogenous DNA into host cells by transforming cells with replicative/integrative vectors, and then replicating the cells a number of times under selective pressure to promote retention of the vector in subsequent generations. The replicated vectors thus serve to integrate multiple copies of the exogenous DNA into the host cells throughout the replication/selection phase. Thereafter the selective pressure can be removed to promote loss of the vector in subsequent generations, leaving stable integrants of the exogenous DNA.

Title: Multi-state shippable lampshade
Inventor: LEE DOMINIC
IPC: F21Y101/00
Filed: 1998-12-29
Granted: 2005-10-25
Abstract: A protective, reversibly convertible lampshade. A first rigid frusto-conical section is adapted to receive a bulb socket. A second intermediate section is coupled to the first section and has a generally frustumated cone shape with the narrower end coupled to the broader end of the first frusto-conical section. The second section has a series of radially oriented slits for providing flexible movement of the second section relative to the first section. A third, frusto-conical section, the narrower end of the third frusto-conical section is coupled to the wider end of the second frusto-conical section.      The third frusto-conical section is formed of a rigid material.      Application of force to the first and second sections acts to cause the intermediate section to bend and fold relative to the first and third sections so that the volume of the lampshade is reduced in a reversible fashion.

Abstract: A tee nut includes a shaft portion and a flange portion outwardly extending from a first end of the shaft portion. The shaft portion includes a step around the periphery thereof at an intermediate position of its axial length, a forward end side cylindrical portion having a hollow cylindrical shape located between the second end of the shaft portion and the step, and a base end side enlarged cylindrical portion having inner and outer diameters larger than those of the forward end side cylindrical portion. The forward end side cylindrical portion includes a predeterminate caulked part formed over a prescribed length from the second end and a female screw forming part between the step than the predeterminate caulked part. According to this structure, the length of the forward end side hollow cylindrical portion including the female screw forming part can be relatively reduced, and hence the length of the female screw forming part is not increased beyond necessity but can be set at the minimum necessary value agreeing with a standard such as ISO standard even if the shaft portion has a large length. Thus, no additional working is required in a threading step with a tap and the productivity of the tee nut can be improved.

Abstract: This invention takes advantage of the finding that neurite outgrowth and nerve regeneration are promoted by disruption of the steroid receptor complex. This disruption can take the form of disruption of the physical assembly or function of the steroid receptor complex, such as the mature complex or a precursor of the mature complex that is required for assembly of the mature complex. Geldanamycin and its analogs, as well as FKBP-52 antibody, are shown to disrupt the complex and promote nerve growth. In addition to these compounds, the invention includes assays for finding neurotrophic compounds, as well as compounds found by these assays, pharmaceutical compositions into which they are incorporated, and methods of treating subjects having neuronal dysfunction caused by injury or disease.
