  • Patent number: 6296391
    Abstract: A hydrodynamic bearing apparatus comprises two hydrodynamic bearing sections which have a shaft member, a bearing member fit to the shaft member with a predetermined space therein, lubricants filling the space between the shaft member and the bearing member, and which are separately placed in the axial direction of the shaft member. The lubricants of the two hydrodynamic bearing sections are separated from each other by an air layer. The lubricants are pressured by hydrodynamic generating grooves formed on the hydrodynamic bearing sections such that the shaft member and the bearing member are rotatably supported in relation to each other. The hydrodynamic generating grooves separately formed on the two hydrodynamic bearing sections are formed into an unbalanced shape such that the lubricants are moved in a predetermined direction to correct the slope of the shaft member and the bearing member when rotation is suspended.

  • Patent number: 6155721
    Abstract: A dynamic-pressure fluid bearing comprises bearing parts formed by a pair of dynamic-pressure surfaces. One of the dynamic-pressure surfaces of the bearing parts is a polyamideimide coating thicker than 3 .mu.m and the other surface is metal. The bearing is particularly applicable to driving motors for polygon mirrors. In addition, a so-called particle removing function is added to one or more of the surfaces of the bearing parts or a position nearby that causes easier removal of dust and other particles accumulated on the parts.

  • Patent number: 6126643
    Abstract: The blood collecting syringe is constructed for coupling with an arterial blood sampling system. In one embodiment, upon retraction of a plunger, a collapsed hollow deformable stopper expands to draw any air bubble and fluid into a small discard chamber within the stopper. Continued retraction of the plunger causes the stopper to also retract thereby forming a specimen collecting chamber within the distal end of the barrel for receiving whole blood from the sampling system. In another embodiment, the plunger has a cap mounted within a hollow stopper so that upon movement of the cap from a forward position within the stopper to a retracted position within the stopper, a discard chamber is formed within the stopper while at the same time, any air bubble and fluid is drawn into the discard chamber. Subsequent movement of the plunger also causes retraction of the nozzle thereby opening up a blood specimen collecting chamber.

  • Patent number: 6122383
    Abstract: A device is provided for reducing noise in the human ear having a microphone which picks up the noise and a reproduction transducer to which a noise compensation signal is fed via a compensation circuit which is connected with the microphone. The microphone in the device has a balancing element which is arranged in front of the sound entrance opening of the microphone. The balancing element defines a quasi-constant sound reflection and accordingly reduces individual reflection effects caused by the fundamental diversity of the external region of the human ear and improves the use of the entire device and increases the effectiveness of the noise compensation overall. In this way, headphones/hearing protectors can also be designed as acoustically closed systems which are designed so as to rest on the ear.

  • Patent number: 6095975
    Abstract: An apparatus and method for determining optimal locations for placing radioactive seeds at a cancerous site. After a plurality of cross-sectional images of the cancerous site are obtained, a contour of an area on each cross-sectional image of the cancerous site is defined and transferred to a three-dimensional coordinate system. Then, a population of locations within each area of each cross-sectional image of the cancerous site where radioactive seeds can be placed is identified. A genetic algorithm is then implemented to determine the optimal number of locations within the cancerous site to place the radioactive seeds.
