Abstract: A gap measurement device 1 comprises a light source 5 for projecting light on a gap 3 to be measured, a lens optical system 6 for focusing on an imaging surface 7 a gap image 3A from light transmitted through the gap 3, and a light-receiving element 9 for receiving light of the gap image 3A formed on the imaging surface 7 of the lens optical system 6. A holed mask 8 provided with a light-transmitting hole 8a having a prescribed aperture size is arranged on the imaging surface 7, and the light-receiving element 9 receives the light of the gap image 3A via the hole 8a. A gap size at a point to be measured in an extended gap 3 can be measured by forming an image of the gap with the lens optical system 6 and placing the hole 8a of the holed mask 8 on the point to be measured on the imaging surface 7 of the lens optical system 6.

Abstract: An externally toothed gear of a strain wave gearing is made to flex into a shape conforming to an ellipsoidal curve. The externally toothed gear meshes with an internally toothed gear at the major-diameter position of the ellipsoidal curve. These two meshing positions gradually change in the circumferential direction of the both gears along the tooth trace direction. The number of external teeth of the externally toothed gear participating in meshing with the internally toothed gear can be increased. A strain wave gearing which has a high rigidity and is capable of reducing vibrational noise, can be realized.

Abstract: In a self-calibration method of an angle detector, an angle interval between first and second scale reader heads are set, so that a single rotation is not equally divided into an integer number of potions by a value of the angle interval and that a plurality of rotations N are equally divided into M equal portions by the value of the angle interval. Readings by the scale reader heads during N rotations of the divided circle are obtained at a pre-set data sampling interval. From differences in readings by these scale reader heads, data of the sequential two-point method relating to an angle scale error of the divided circle are obtained at the data sampling interval. The scale error of the divided circle at the data sampling interval is calculated by synthesizing the data using the fact that an average of the data for the rotations N reaches approximately zero.
