Title: Grinding and apparatus thereof
Inventor: KOIKE YOSHIO
IPC: B24B29/00
Filed: 1984-03-29
Abstract: PURPOSE:To automate the finishing work for the metal burrs at the worked edge and bulging-out part without accompanying danger by beating and grinding a worked surface by revolving a wire brush which is soft and has a relatively large diameter of strand at high-speed, in substitution for grindstone. CONSTITUTION:An electric motor, air turbine, etc. are used as a high-speed rotary prime mover 2 for a wire brush 1 of a wire-brush grinding mechanism, and a wire brush holding structure 3 is held by a brush revolving bearing part 4. On operation, the wire brush 1 is revolved at a high-speed over the peripheral speed of a grindstone, and turned by a turning prime mover 6. Since the rotary prime mover has a power line, the disposal for the entanglement of electric wires, hose, etc. through unidirectional turning is troublesome. Therefore, normal and reverse revolutions are repeated by forming restrictions in 360 deg. or so, and then the entanglement of hose and electric wires can be prevented, and the grinding in all directions is permitted.

Title: Method of controlling position of probe
Inventor: BANDO HIROSHI
IPC: G05D3/00
Filed: 1988-03-15
Abstract: PURPOSE:To maximize a control range of a probe position control loop for a projection and a recession on the surface of a sample in both directions of the projection and the recession, by controlling an output voltage of another control loop so that a control voltage of the control loop be about 1/2 of a control voltage range thereof. CONSTITUTION:A rough motion mechanism 5 is operated to approach a probe 1 to a sample 3 at a distance whereat a tunnel current flows between the probe 1 and the sample 3. At this time, a control loop A outputs a voltage VA for displacing a fine motion element 2 to a distance whereat a set tunnel current flows between the probe 1 and the sample 3. For controlling the fine motion element 2 so that the tunnel current flowing between the probe 1 and the sample 3 be fixed when the sample 3 is moved in the direction of (x) or (y), a control range effective for a projection and a recession of the unknown sample 3 is easy to obtain if the initial value of the voltage VA is about 1/2 of the control range of the control loop A. Therefore, a voltage VB of a control loop B is controlled so that VA be about 1/2 of an output voltage of the control loop A.
