Abstract: A method of dynamically tuning a computer system including a memory having a plurality of pages which is subjected to varying system loads based on the number of processes handled by the computer system is provided. Each process has an associated run priority.  First, the current system load is determined. The current system load is then compared with the system load for which the computer system has been statically tuned. The computer system is statically tuned by the setting of tuning parameters. Finally, the tuning parameters are dynamically adjusted so as tune the computer system to the current system load.

Abstract: A catheter equipped with an expansible member according to the present invention comprises  a first lumen whose tip is open, a second lumen whose tip is closed, a foldable expansible member communicating with the second lumen, and a rigidity imparting member consisting of a linear member extending in the axial direction disposed in the second lumen. Therefore, an extreme flection or bend of the catheter is prevented without decrease of the flexibility of the catheter, especially the elastic deformability in the lateral direction with respect to the axial direction of the catheter. Thus, the force applied to the base end portion of the catheter for advancing the tip end portion thereof is surely transmitted to the tip end portion. Further, a catheter equipped with an expansible member according to the present invention comprises a first lumen whose tip is open, a second lumen whose tip is closed, and a foldable expansible member communicating with the second lumen, the outer diameter of the tip end portion of the catheter including a portion to which the expansible member is attached is smaller than that of the base end portion of the catheter. Therefore, the tip end portion of the catheter can be inserted into a severer stricture portion or in a more peripheral blood vessel. Further, a catheter equipped with an expansible member according to the present invention comprises a first lumen whose tip is open, a second lumen whose tip is closed, and a foldable expansible member communicating with the second lumen, the tip of the expansible member forming the tip of the catheter. Therefore, the expansible member is prevented from peeling off and the tip end of the catheter is prevented from being an injury to the inner wall of a blood vessel when the catheter advances in the blood vessel.

Granted: 1997-11-04
Abstract: A window for automobiles or the like includes a window plate and an integral frame member along at least one edge of the window plate.  The window is manufactured by preparing a window plate and a pre-shaped frame body which comprises a main portion and a surface layer covering an outer side of the main portion.  The main portion of the pre-shaped frame body is composed of a thermoplastic synthetic resin material having a relatively high dielectric loss and containing a heat foamable agent therein.  The surface layer is composed of a non-foamable thermoplastic synthetic resin material.  The pre-shaped frame body is subjected to a dielectric heating in a mold, to cause the foamable agent in the main portion of the pre-shaped frame body to expand in the mold cavity.  The resultant frame member of the window comprises a main portion composed essentially of a foamed thermoplastic synthetic resin material, which is covered on its outer side by a surface layer composed essentially of a non-foamed thermoplastic synthetic resin material.

Abstract: ABSTRACT      An aquarium-terrarium tank providing a semi-aquatic animal with a natural environment and which solves the problem of filtration in tanks of this nature.  A shortened side wall enables an over the side filter to operate effectively while permitting a reduced water level to be maintained within the tank.  A dry, land area may then be provided for the animal within the tank without the danger of escape.  In one embodiment, the opening above the shortened side wall is restricted by the permanent addition of at least one panel affixed between the top edge of the shortened side wall and the edge of the adjacent full height side wall such that it is in the same plane as the shortened side wall.  In a further embodiment, the closure consists of a removeable panel containing a cut-out of appropriate size to accommodate the size of the filter selected.

Title: Arylpiperazinylbutyl-dihydroindoles and related compounds
Inventor: PERREGAARD JENS
IPC: C07D231/54
Filed: 1989-12-21
Granted: 1999-09-14
Abstract: The present invention relates to novel piperazinylbutyldi-hydroindoles, piperazinylbutylindazoles, the corresponding 2,3-dihydro derivatives, and 2-indolones, having the following formula   wherein the various symbols have the meanings set forth herein, which have been found to have central serotonin activity with preference for the serotonin 5-HT1A receptor.   Compared to the anxiolytic drug buspirone, and other clinically investigated compounds such as ipsapirone and gepirone, most of the present compounds have lower efficacy at the 5-HT1A receptor which implies less side effects related to activation of the receptors.      The invention also includes acid addition salts and pharmaceutical compositions and their preparation for treating CNS disorders occurring in anxiety, depression, aggression and in alcohol abuse, or in states of disease related to the cardiovascular, gastrointestinal and renal systems, by administering the aforementioned compounds.   Separation and use of the stereo isomers of the 2,3-dihydro derivatives and 2-indolones are also part of this invention.

Abstract: A hemodialysis system has a blood circuit and a hemofiltrate circuit interconnected at a hemo-filter and an air collection chamber. If an infusion of sterile fluid to the returning blood is needed during the dialysis treatment, filtrate in the filtrate circuit is pumped back into the blood circuit. This is also done to purge the blood circuit of blood and return it to the patient at the conclusion of a dialysis treatment. A blood pump in the blood circuit incorporates a flexible vessel in conjunction with pinch valves which self expand in a controlled manner from a compressed condition to fill with blood from the patient in a suction stroke controlled by the patient's blood delivery rate. Compression of the vessel by an external member then forces the blood through the rest of the blood circuit:

Abstract: An electrical wire connector has a bifurcated bolt having opposed prongs coextending spaced from each other defining a wire-receiving channel therebetween. A nut is threaded onto the bolt until an insert carried by the nut is pressed tightly against one of the two wises disposed along the channel, to clamp the wires tightly against the bottom of the channel and electrically interconnect the wires. The nut has an internally threaded lower section within which a body section of the insert is disposed, and an upper section joined to the lower section at a frangible section adapted to brew upon sufficient torque being applied to the nut by a tool, thus providing a torque limit and a visual indication of full assured interconnection. The insert has a lower section depending from the body section having tabs extending outwardly under a lower edge of the nut, far the nut to deflect the tabs downwardly against the wire during final stages of application of the connector to the wires, with the tabs providing stored energy to the center insert portion springably urged against the wire during long-term in-service use.
