  • Patent number: 8120750
    Abstract: When a substrate stage is located in a first area, a first measurement device measures the same portion of the substrate at the plural measurement points both before and after the stage is horizontally driven. A controller calculates a first difference of the stage in the vertical direction in the first area accompanying driving of the stage horizontally, based on a first measurement result, calculates a value representing a surface shape of the substrate by subtracting the first difference from the first measurement result, calculates a second difference of the stage in the vertical direction in the second area accompanying driving of the stage horizontally by subtracting the value from a value representing a vertical position of the substrate when the stage is located in the second area, and controls a vertical position of the stage in the second area based on the second difference.

    Abstract: A reel for winding an elongated body includes a rotor 30 that pivots relative to a casing, a free roller 22 located on the outer peripheral side of the rotor 30, and an inner reel section 30 formed on the inner side thereof. An elongated body is wound in one direction on the outer periphery of the inner reel section 23, and the elongated body extending from the inner reel section is reversed by a reversing roller 21, wound in the other direction on the outer periphery of the free roller 22, and pulled out to the outer periphery of the rotor. The inner reel section 23 is adapted to be pivotable relative to the rotor 30. The pivot shaft of the inner reel section 23 is placed at a position different from the position of the center axis 11 for pivoting of the rotor 30. The reel has a pivoting device for pivoting the inner reel section 23 such that the rotor 30 and the inner reel section 23 pivot in the directions opposite to each other with substantially the same angular speed.

  • Publication number: 20080241058
    Abstract: A method for producing hydrogen including the steps of supplying a raw material gas from a gas inlet of a reactor tube; producing a gas mixture containing hydrogen, carbon monoxide, and carbon dioxide by a reforming reaction and a shift reaction; recovering, from a discharge outlet of a separator tube, hydrogen being isolated by passing through a permselective membrane into the separator tube from the gas mixture; and discharging other gas components incapable of passing through the permselective membrane from a gas outlet of the reactor. Hydrogen is produced under conditions where ? defined by the following equation is in the range of 0.4 to 100: ?={(CO2)/(CO)2}/K wherein (CO2) and (CO) denote the partial pressures of carbon dioxide and carbon monoxide at the gas outlet and K denotes the equilibrium constant of the disproportionation reaction of carbon monoxide at the internal temperature of the reactor tube.

  • Publication number: 20080204007
    Abstract: A wheel speed sensor includes a hall IC that outputs a signal representing a change of magnetic field generated by rotation of a detection object and that is simply covered with resin coating. In the process of molding the resin coating, a resin injection opening is positioned away from an end face of a sheath of a cable to be coated by a length no less than a minimum adhesion length for ensuring adhesion between the sheath and the resin coating. In addition, the holder and a cover of the detector are provided with waterproof protrusions extending along the entire peripheries of contact areas in which pressing pins are brought into contact with the holder and the cover. Accordingly, immersion of the detector is reliably prevented even when a void or the like occurs in the resin coating at a position near the injection opening.
