Title: Ultrasonic motor
Inventor: KAWAI SUMIO
IPC: H02N2/00
Filed: 1990-05-18
Abstract: PURPOSE:To enable highly accurate positioning of a moving member with respect to a fixed member by employing a hollow frame, having axis in parallel with the moving direction of the moving member, as the fixed member or the moving member. CONSTITUTION:A moving member, i.e., a moving frame 2, comprising a hollow cylindrical body is arranged movably in the axial direction at the inside of a fixed member, i.e., a fixed frame 1, comprising a hollow cylindrical body through a predetermined gap, and a slide board 3 extending in the axial direction of the moving frame 2 is secured to the moving frame 2 at a part above the gap between the fixed frame 1 and the moving frame 2. When an oscillator 12 disposed at a position facing with the support 13b of the moving frame 2 is pushed in the axial direction O through the slide board 3, centripetal function is produced by linear grooves 1a-1c, 2a-2c and the supports 13a-13c and thereby the moving frame 2 is aligned accurately and precisely to the fixed frame 1.

IPC: G03B27/52
Filed: 1978-10-19
Abstract: PURPOSE: To raise copying speed, by moving both an image forming lens system and a plane mirror to shorten the movement distance to an exposure optical system.  
     CONSTITUTION: The light axis of image forming lens system 2 is kept perpendicular to original platen face 1, and installed movable in the direction of an arrow perpendicular to its own ligh axis. Where the distances between lens system 2 and an object, and an image are a and b, respectively, magnification m becomes b/a. Where the scanning distance of face 1 is XO, the movement distances of system 2 and reflective mittor 3 are XL and XM, respectively, the relationship of the above distances becomes formula I. One of XL and XM can be optionally selected and the other is difined by this. Where XL=0 or XM=0, formula II or III is obtained and they are the movement distances, respectively, where mirror 3 or system 2 is moved alone. where both are moved, dustances XL, XM are shortened, thus permitting copying speed to be raised.

Title: Booster
Inventor: SATO TORU
IPC: B60T13/56
Filed: 1995-04-28
Abstract: PURPOSE: To allow an output shaft and a valve body to smoothly slide against each other to prevent abnormal noises from being made by providing a connecting member between a piston and the valve body, for connecting both of them together in such a manner that they can be displaced relative to each other in the direction of an axis but cannot be bent. CONSTITUTION: An output shaft 14 is slid and displaced to the rear side relative to a valve body 3 at the compression of a reaction disk 30. At the same time a piston 32 is also slid and displaced to the rear side relative to the small diameter part 33A of a connecting member 33 integrated with the valve body 3. The connecting member 33 prevents the piston 32 and the valve body 3 from being bent when moving back and forth, thereby preventing a base part 14A of the output shaft 14 from being bent relative to the valve body 3. Noises caused by an increase in sliding resistance due to bending of the output shaft can thus be prevented.
