  • Patent number: 9046521
    Abstract: The object of the present invention is to identify a molecule that is specifically recognized by antibody RM2 in tissue or serum of a cancer patient, and provide a method for diagnosing cancer in a simple manner with high specificity using the molecule as an indicator. The present method comprises evaluating a risk or grade of malignancy of genitourinary cancer in a subject using the level of the haptoglobin ? chain to which antibody RM2 specifically binds or a fragment thereof in tissue or body fluid isolated from the subject as an indicator.

  • Publication number: 20090009742
    Abstract: A permanent magnet fixed to a peripheral portion of a lens cell includes two magnets that are joined together so that the north poles face each other and the south poles are exposed. A first driving coil is arranged to face toward exits for lines of magnetic force from the joining surfaces of the north poles of the permanent magnet, and a second driving coil is arranged to face toward entrances for lines of magnetic force in the permanent magnet. The orientation of the lens is adjusted by adjusting the currents supplied to the first driving coil and second driving coil to drive the lens cell in an optical axis direction and horizontal direction in a state in which the lens cell is levitated relative to the cover.

  • Publication number: 20080285003
    Abstract: A reticle blind which is capable of being opened and closed at a relatively high speed and which does not cause mechanical disturbances or reaction forces. The reticle blind includes two reticle blind assemblies designed to cooperate with one another to control the passing of a laser beam of an exposure system onto a work piece, such as a semiconductor wafer or flat panel display. Each reticle blind assembly includes a linear motor having a mover and a blind configured to be positioned between a first position and a second position by the mover. Each reticle blind assembly also includes a counter mass assembly including a portion of a guide mechanism having at least one guide bar and a stator of the linear motor. The stator of the linear motor and the guide bar are integrated to form the counter mass which is configured to absorb reaction forces that are created when the blind is moved. In various embodiments, the blinds can be configured to operate in the vertical or horizontal orientation.

  • Publication number: 20060033043
    Abstract: A table with six degrees of freedom, such as a wafer table for a lithography system, has an upper table stacked on top of a lower table. Each of these two stacked tables has three degrees of freedom and is provided with actuators for controlling its motions in these three degrees of freedom. The vertical motion, the pitching and the rolling of the lower table may be controlled by actuators that may be voice coil motors. The upper table is supported on the flat top surface of the lower table so as to be slidable laterally, or two dimensionally. This two dimensional motion of the upper table and its yaw may be controlled by another set of actuators which may be smaller voice coil motors. A wafer holder supporting a workpiece such as a wafer for the lithography system may be secured onto the upper table by a vacuum suction mechanism.

  • Publication number: 20050057102
    Abstract: A coolant cools an object (such as, for example, a coil of a linear motor that drives a stage of an exposure apparatus) while suppressing the generation of a temperature distribution in various parts of the object being cooled by using a coolant that includes a first component and a second component dispersed in the first component, the second component increases in temperature by a lesser amount than the first component when a predetermined amount of heat is absorbed by the first and second components, respectively. The second component may be a substance that changes phase (for example, from a solid to a liquid or from a liquid to a gas) in order to absorb the predetermined amount of heat. The second component may have a higher heat capacity than the first component, and may not change phase when it absorbs heat to cool the object.
