  • Sheet transfer device with guide plates and hold rollers
    Patent number: 6648328
    Abstract: To prevent wavy swell from causing in sheet in transferring thereof and avoid wrinkle from being produced in later printing steps, there is provided a sheet transfer machine forward from a printing drum and a press roll. The machine is provided with upper and lower guide plates respectively formed with hole portions. Upper and lower rolls are disposed at the hole portions. There are provided hold rollers for pressing sheet coming from between the upper and the lower guide plates to an upper face of the lower guide plate downstream from the upper roll in a direction of transferring print sheet. In printing, swell is prevented from being produced by pressing the print sheet coming from between the two rolls by the hold rollers. When the sheet is sandwiched by the printing drum and the press roll and printed in later steps, wrinkle is not produced in the print sheet.

  • Liquid chromatograph mass spectrometer
    Patent number: 6646254
    Abstract: A liquid chromatograph mass spectrometer includes a solvent removing tube, a first ion lens and a second ion lens. Voltages applied to the solvent removing tube, and the first and second ion lenses corresponding to each mass number of a standard sample are studied in advance so that efficiencies of passing ions become best. A voltage scanning pattern is made based on the impressed voltages, and stored in a memory portion. When a scanning measurement is carried out, a control portion controls a current voltage source and a high frequency voltage source according to the voltage scanning pattern, synchronizing with the scanning of the impressed voltage to the quadrupole filter. As a result of the control, an objective ion which is generated by being atomized from a nozzle may effectively pass through the entrance of a quadrupole filter.

  • Radiation tomography device
    Patent number: 6643352
    Abstract: In a radiation tomography device, in case a wide photographing area is required, even if a resolution capability in a depth direction of a section of a subject including an intersection of a rotation axis and a radiation irradiating axis is low, a small Laminographic angle &agr;1 is set. In case a high resolution capability is required in the depth direction, even if the photographing area is narrow, a large Laminographic angle &agr;2 is set. Since a balance between the resolution capability in the depth direction of the subject and the photographing area can be adjusted by varying the Laminographic angle, the photographing modes can be freely selected to thereby carry out the tomography suitable for the photographing requirement.
