Title: Scanning type probe microscope
Inventor: NAGAOKA HIDEKI
IPC: H01J37/28
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To improve lateral resolution, by detecting the displacement of a scanner in X and Y directions caused by a voltage impressed on Z-direction response and feeding back the displacement signal, and suppressing oscillations in the X and Y directions. SOLUTION: As oscillations in X and Y (two dimensional) directions are determined according to the mechanical natural frequency of a cylindrical scanner and is approximately constant, the detection signals of a lateral sensor only in the vicinity of the mechanical natural frequency are extracted by a band pass filter. Next, the difference between the oscillations in the X and Y directions and the target location of lateral scanning is amplified by an integrating amplifier K3 /S to obtain the amount of displacement E2 from the target location of scanning in the X and Y directions due to the oscillations in the X and Y directions. Then the amount E2 of displacement is subtracted from the first Z (vertical) direction movement instructing voltage E1 to obtain the final Z direction movement instructing voltage E3 .  As the response of a servo in the Z direction is lowered, and the oscillations in the X and Y directions caused by the movement in the Z direction are reduced by this control, it is possible to obtain images with high lateral resolution.

Filed: 1987-03-28
Abstract: PURPOSE:To stably operate a constant voltage static CMOS/RAM even when a power source voltage is low, by performing pre-charge while a word line is closed. CONSTITUTION:When a pre-charge signal phic changes from an L to an H, the change of the signal is transferred from a NOR gate G1 to a G gate via a pseudo decoder DD and a pseudo memory cell DM, and an internal pre-charge signal phic' changes from the L to the H. At this time, the word line which drives the memory cell DM becomes active with a little delay due to a the delay time at the decoder DD. Next. when the signal phic changes from the H to the L, the two-input NOR gate G is set an state, however, the signal phic' does not change immediately, and a state is set the one waiting for an input on the side. In other words, the signal phic' changes after the word line changes from the H to the L. In such a way, the pre-charge can be performed while the word line is closed.
