Abstract: A mobile vehicle 1 has two wheels 5, 5 on the rear side of a vehicle body 3, and is capable of causing a roll driving moment to act on the vehicle body 3 by an actuator 33 in a roll driving mechanism 23. A control device 70 controls the actuator 33 such that the function characteristics of the roll driving moment implemented by the control of the actuator 33 with respect to a vehicle body roll angle (inclination angle in the roll direction of the vehicle body 3) become as shown in FIG. 6A or 6B.

Abstract: A force sensor unit includes: a detection section constituted of a main unit detecting external force and changes in temperature, and a sub unit detecting the changes in temperature, detecting the external force; and an attenuator dampening the external force and imparting the dampened force to the detection section.

Abstract: A processing apparatus capable of grinding an arcuate groove (a groove having an arcuate shape in section) of various shapes defined in a work with a good accuracy. A pseudo-elliptic arcuate groove defined in a work is ground by a forming grindstone. The work is moved in a Y-axis direction (vertically on a paper sheet) in a state in which the forming grindstone is supported on a tool table for rotation and is moved in a X-axis direction (a direction perpendicular to the paper sheet) to abut against the arcuate groove, while rotating the work in a direction of an arrow with its axis L matched with an axis C of an indexer. Thus, it is possible to relatively move the forming grindstone to trace the arcuate groove, thereby accurately grinding the arcuate groove.

Abstract: An abrasive wheel made of an abrasive which is chemically reactive with a ceramic workpiece and a binder mixed with the abrasive is held against the ceramic workpiece at a temperature ranging from 40.degree. C. to 300.degree. C. preferably 100.degree. C. to 180.degree. C., under at least an atmospheric pressure in a moistening atmosphere within a pressure vessel. The abrasive wheel is rotated in abrading contact with the ceramic workpiece. A surface layer of the ceramic workpiece which is held against the abrasive wheel is mechanically abraded and also subjected to a tribochemical reaction with the abrasive wheel, so that the surface layer of the ceramic workpiece can smoothly and neatly be removed from the ceramic workpiece. The ceramic workpiece thus ground is finished highly accurately and efficiently.
