  • Paper transport system
    Patent number: 5324018
    Abstract: A paper transport apparatus has an inclinable feed-in tray. Documents are drawn from the feed-in tray with a feed roller operating in conjunction with a retard roller. The rollers and the feed-in tray are supported on a pivotable frame. Pivoting of the frame permits the feed-in tray to be inclined to a desired angle to facilitate feeding of documents that do not readily slide while resulting in the documents being fed to the rollers at a constant entry angle irrespective of the angle of inclination of the feed-in tray.

  • Laser interferometer type length measuring apparatus and positioning method using the same
    Patent number: 5141318
    Abstract: In a laser interferometer type length measuring apparatus, a measurement laser beam will be influenced by disturbance such as air fluctuation and a change in air pressure distribution due to movement of an object so that a displacement of the object cannot be accurately measured. In order to obviate such an inconvenience, air controlled at a predetermined temperature is uniformly blown at a fixed speed on the entire optical path of the measurement laser beam.
