Title: Magnetic force microscope
Inventor: SHIKAKURA YOSHIAKI
IPC: G01N27/87
Filed: 1993-03-08
Abstract: PURPOSE:To remove influence of a recess and projection on the surface of a sample, and discriminate a magnetic domain structure easily by impressing two kinds of large and small DC voltages alternately with every scanning line. CONSTITUTION:When voltage V1 of about 8V is impressed between a sample 17 and a leaf spring 1 from a DC voltage impressing circuit 11, a probe detects both forces of magnetic force and electrostatic attraction force. Output of a distance control circuit 13 is converted into a digital signal by an A/D converter 15, and it is inputted to a computer 16. Next, when voltage V2 of about 1V is impressed, though force applied to the probe is almost put under control of Vander-Waals force, measurement data is similarly inputted to the computer 16. A data value of the voltage V2 is subtracted from a measurement data value of the voltage V1 by the computer, and it is converted into magnetic force data. This operation is repeated until in-plane scanning is finished, and an image is formed, and an magnetic force image from which influence of a recess and projection on the surface of the sample, can be obtained.

Abstract: PURPOSE:To improve sharply the using efficiency of a photoconductive material by forming a mechanism capable of moving following each base body so that a steam blowout port is opposed to the base body approaching to an evaporation source and passed through the upper part for a prescribed period. CONSTITUTION:A guide shaft 24 for coupling a guide pole 23 slidably with the evaporation source 15 through a slit 25 is fitted to the evaporation source 15. When an eccentric cam 27 arranged on the intermediate part between the guide shaft 24 and the supporting point shaft 26 of the guide pole 23 is rotated in the arrow C direction by a rotary shaft 28, the guide pole 23 is reciprocated around the supporting point shaft 26 by the action of a bridging spring 29 as shown in the arrow D and the evaporation source 15 is also reciprocated on a guide rail 21 interlocking with said reciprocation. Consequently, the evaporation source 15 can oppose its steam blowout port 16 to respective base bodies passing through the upper part and move following the base bodies by a prescribed distance, so that the using efficiency of the material can be sharply improved.

The output of the oscillator has its phase suitably varied by a phase shifter 9 so that the resonant signals amplified are fed as DC output signals to the vertical axis of a display device 11 by a phase detector 10. The output of the sweeper 6 is partially fed to the horizontal axis so that the horizontal axis is synchronized with the magnetic field sweeping voltage. In order to get the double resonance, a second irradiating power is added at the input to the sample from a second frequency source 12. On the contray, the output of the sweeper 6 synchronized with the device 11 is fed to an automatic adjustor 14 so that it is then fed to the oscillator 12.

Abstract: PURPOSE:To prevent any abrasion of tooth parts and improve sealing ability by forming grooves on a gland part and engaging in a wedge form, with the grooves the tooth parts made of the material with a smaller coefficient of thermal expansion than that of a rotor's material and excellent in erosion resistance, and thereby forming a labyrinth. CONSTITUTION:A plurality of dovetail grooves 12 are formed on the gland part 11 of a rotor 10 at right angles in an axial direction, while tooth parts 13 which are trapezoidal in their cross sections are respectively engaged with the dovetail grooves 12 so that labyrinth is formed. The dovetail grooves 12 have narrower entrances than their bottom surface, and are formed with their side walls being inclined, while the side walls of dovetail grooves 12 are engaged in a wedge form with the tooth parts 13. The tooth parts 13 are formed of a material which has a smaller coefficient of thermal expansion than that of a material forming the rotor 10, and is excellent in erosion resistance, such as fine ceramics. The tooth parts 13 are thus fixed to be projected outwards within the dovetail grooves 12 through springs 16. Consequently, the abrasion of tooth parts 13 due to steam is prevented, while the high steam sealing function is obtained.
