  • Patent number: 7162233
    Abstract: In an elevator call registration system, elevator-related information is constantly transmitted from an elevator call registration server, and a call registration reservation for a desired elevator can be made by selecting contents from the information. Therefore, it is not necessary for the user to access a site where necessary contents are stored, enabling an easy call registration reservation. Further, since the call registration detects that the user is approaching the reserved elevator, the car is positioned at a good time and the user can smoothly go to a desired floor.

  • Patent number: 6014421
    Abstract: An X-ray reduction exposure apparatus which provides a preferable image forming system in an entire mask surface area of a reflection type mask, can reduce curvature of the field and astigmatism of the transfer image even in scan exposure and, therefore, can obtain high transfer precision, and the apparatus contributes to the manufacture of a semiconductor element having high reliability. The X-ray reduction exposure apparatus has, as a characteristic feature, a drive mechanism for driving a mask scan stage substantially along the curvature surface of the mask. This drive mechanism is constituted by a main drive section (linear motor or the like) linearly driven in a direction corresponding to the moving direction of a mask scan stage and a sub-drive section (actuator or the like) driven perpendicularly to the drive direction, otherwise, constituted by a main drive section and a guide having a shape which is the same as the curvature surface shape of the mask.
