  • Patent number: 7965819
    Abstract: An irradiation field limiting device includes a plurality of aperture leaves arranged in a thickness direction, a flexible linear member secured to a thick portion of the aperture leaf, a driver section which drives the linear member a specific amount, and the like. One end of the linear member is secured to an aperture leaf through a connection section tangentially to the outer arc of the aperture leaf, and the other end is connected with a slider provided in a driver section. The slider is connected with a driving source through a connection portion and moves along an axial direction of a drive shaft inserted into a base accompanying rotation of the drive shaft. A load accompanying the movement of the slider is directly transmitted to the linear member, and the aperture leaf is driven a specific amount due to the load.

  • Publication number: 20080260498
    Abstract: A connecting device is provided to a wafer carrier for storing a wafer and connected to a purge port having a gas inlet into which a gas for purging an atmosphere in the wafer carrier flows. The connecting device includes, a base; a communication port formed in the base; and a close-contact mechanism that includes, a sealing ring, a groove, and a pressure-reducing passage that communicates with the groove. The pressure in a space defined by the groove and a peripheral edge of the gas inlet is reduced at a position where the base makes contact with the purge port, bringing the gas inlet into close contact with the communication port.

  • Patent number: 7360898
    Abstract: The present invention provides an eye accommodation function state measurement device which places only a small burden on the subject, allows confirmation of an intermediate measurement result, and is more conveniently used. The eye accommodation function state measurement device disposes an image at a plurality of positions by using an image moving mechanism, and measures the accommodation function state of the subject's eye at each position. The eye accommodation function state measurement device includes a control section (65) which provides a measurement suspension period (S6 to S10) in which the measurement is suspended. In the measurement suspension period, the eye accommodation function state measurement device calculates the eye accommodation function state (S7), displays the intermediate measurement result of the eye accommodation function state (S8), or transmits data from the control section (65) to an external storage section (69) (S9).
