  • Publication number: 20030095697
    Abstract: A computer-aided diagnostic method and system provide image annotation information that can include an assessment of the probability, likelihood or predictive value of detected or identified suspected abnormalities as an additional aid to the radiologist. More specifically, probability values, in numerical form and/or analog form, are added to the locational markers of the detected and suspected abnormalities. The task of a physician using such a system as disclosed is believed to be made easier by displaying markers representing different regions of interest.

  • Publication number: 20030083427
    Abstract: For use as a wet strength agent, a water-soluble blocked urethane prepolymer having a hydrophilic group and a blocked isocyanate group is combined with a cationic charge-adjusting agent. The adsorption and retention of the water-soluble blocked urethane prepolymer to cellulosic fiber are promoted by virtue of the cationic charge adjusting agent when the wet strength agent is added to a paper-making stock.

  • Publication number: 20020124085
    Abstract: A thread manager makes a request to a resource manager for a hardware resource needed for execution of a thread representative of a function of a logical unit, the resource manager allocates the resource in response to the request, and the thread manager controls an execution state of the thread in accordance with a result of the allocation. The thread and resource managers conduct the request, the allocation and the control repeatedly in cooperation with each other until the execution of the thread reaches completion, thus achieving a simulation of the operation of the logical unit. Accordingly, through the operation simulation, it is possible to make the confirmation of the function and the evaluation of an architecture at an initial stage of the design of the logical unit, and further to cope flexibly with an alteration of the architecture by means of a minimum change of description.

  • Publication number: 20020089778
    Abstract: The position information of the magnetic head is generated also from the data area to improve the positioning accuracy. The magnetic disk drive has a function of oscillating the magnetic head in the radial direction in the data area at a specific frequency and a function of detecting a read signal during the execution of the oscillation function and detects position information of the magnetic head from the detected read signal. The magnetic head position control can be performed in the data area. The magnetic head position signal not dependent on the frequency of a sampling signal generated from the servo information area can be generated. This in turn improves the data recording density and allows a highly precise position control of the magnetic head, thus improving the reliability of the magnetic disk drive.

  • Publication number: 20020070417
    Abstract: Disclosed is an optical information processor having high-speed reading property by improving responsivity and extension of the frequency band width of a photodiode prepared on one identical substrate together with other semiconductor integrated circuit device. To extend the frequency band width, a buried layer of a photodiode portion is deeply implanted or the impurity concentration of the buried layer is lowered. To improve the responsivity, the thickness of the oxide layer of the SOI substrate is selected such that the reflected light is maximized.

  • Publication number: 20020070843
    Abstract: A thin-thickness variable resistor is provided, which is capable of stabilizing electrical connection between metallic terminals and a resistor by increasing the holding strength for a second terminal by a substrate while preventing the bending strain during the bending work from spreading to a conductive portion conductive to the resistor. A variable resistor comprises a substrate, metallic terminals formed in the substrate by insert-molding, and a slider sliding on a resistor formed on the substrate, wherein the slider is rotatably attached by crimping an eyelet formed in a first metallic terminal. External-connecting portions of the metallic terminals are extended from the bottom portion of the substrate to be bent upwardly along sides of the substrate.
