Title: Scanning probe microscope
Inventor: ITO TAKASHI
IPC: G01B21/30
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the tip of a probe from colliding with a sample surface when the probe is rotated in an image observation visual field. SOLUTION: When the rotation angle of an image observation visual field is set and rotation is instructed during the scanning of a probe, a control device 2 feeds the data of the rotation angle to a rotation calculating circuit 6 after receiving a detection signal from a middle point detecting circuit 5, not immediately. The image observation visual field is rotated at the middle point of the image observation visual field, thus the probe is not moved unlike in the past, and the tip of the probe does not collide with a sample surface. When a change of the image observation magnifying power is instructed during the scanning of the probe, the changing action of the image observation magnifying power is made at the middle point of the image observation visual field, and the tip of the probe can be prevented from colliding with the sample surface.

Title: Rectifier
Inventor: SATOU HIDEYOSHI
IPC: H02M7/217
Filed: 1978-07-06
Abstract: PURPOSE: To improve the efficiency of rectification, by using the linear drain current region of a MOSFET as a turn-on region and reducing the rising voltage and forward loss of a diode.  
     CONSTITUTION: A input terminal 21 of a voltage polarity detection circuit is set at positive potential but its other input terminal 22 is set at negative or ground potential. When the gate 7 of the MOSFET is positive, the drain current flows from a terminal 5 to another 6. If the MOSFET is an n-MOSFET, a terminal 21 and a substrate have the same potential. When the potential on the terminal 21 is higher than that on the terminal 22, the gate is biased positive (VG>V2). When the potential on the terminal 21 is lower than that on the terminal 22, the gate is biased negative (VG< V2). The diode is thus formed, wherein the terminal 5 connected to the terminal 21 is used as the anode and the terminal 6 connected to the terminal 22 is used as the cathode. Since the linear drain current region of the MOSFET is used as the turn-on region, the rising voltage and forward loss of the diode are reduced. Therefore, the switching loss of the MOSFETis decreased.
