Title: Fluid bearing device
Inventor: NAKAMURA TETSUO
IPC: F16C32/06
Filed: 1991-09-05
Abstract: PURPOSE:To provide a fluid bearing device formed in such a way as to attain high rigidity without clearance change even to load fluctuation and to enable the improvement of its damping characteristic to vibration. CONSTITUTION:Pressure oil is supplied into a bearing recess 5 through the throttle clearance of a variable throttle 54 and jetted into a clearance between a track base 2 and a movable base 3. A thus generated clearance H between the track base 2 and movable base 3 is detected by a non-contact displacement gauge, and the throttle clearance of the variable throttle 54 is changed in such a way as to eliminate deviation between this clearance and the set value. Since the clearance is thus controlled to be the set value, the clearance H can be maintained to be always constant even to load fluctuation, and a damping characteristic to vibration can be also improved.

Title: Picture reader and its peak tracking method
Inventor: KUNO KYOSUKE
IPC: H04N1/40
Filed: 1991-10-03
Abstract: PURPOSE:To obtain the picture reader in which an input level of picture data is not incorrectly decreased resulting from tracing with a peak level due to dirt of a reference white bard by starting/stopping the peak tracing in response to a peak level of the picture data before shading correction. CONSTITUTION:A peak rising prevention circuit 21 fixes a reference voltage E when a peak level of picture data A inputted to an A/D converter 13 exceeds a reference voltage E to prevent its rising. The A/D converter 13 outputs an overflow signal (f) when the peak level of the picture data A exceeds the reference voltage E. When the signal (f) is outputted, a Q output of a flip-flop 22 goes to H and a flip-flop 23 is reset. Thus, even when an overflow signal F is outputted from a peak detection circuit 17 due to dirt or dust or the like on the reference white board, the signal is not inputted to a peak hold circuit 18 and the reference voltage E is fixed.
