摘要： An object of the present invention is to provide a dicing blade which does not cause cracking and breaking even in a workpiece formed from a brittle material, and can stably perform cutting process in a ductile mode on the workpiece with high precision. A dicing blade 26 which performs the cutting process on the workpiece is integrally formed of a diamond sintered body 80 which is formed by sintering diamond abrasive grains 82 so as to have a discoid shape, and a content of the diamond abrasive grains 82 of the diamond sintered body 80 is 80 vol % or more. It is preferable that recessed parts which are formed on a surface of the diamond sintered body 80 are continuously provided in an outer circumferential part of the dicing blade 26 along a circumferential direction.

摘要： A three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. The Y carriage is supported by two strut members which are across a surface plate and movable in a Y-axis direction. The two strut members include a first strut member having a driving mechanism and a second strut member which moves following the first strut member. A guide portion parallel to the Y-axis direction is formed in the surface plate on a first strut member side. Side surface support members support the first strut member on the surface plate by holding both opposed side surfaces of the guide portion. The driving mechanism includes a roller having an axis perpendicular to a surface plate surface, and the roller is brought into contact with one side surface of the guide portion and rolled to move the Y carriage relatively to the surface plate.

摘要： A rotation angle measurement device includes: relative angle detection means including a reference support whose rotation is regulated in a fixed range in an arbitrary direction of a rotation axis, and a driving rotating body which is coupled to the reference support and is axially supported so as to be all-round rotatable with respect to the reference support, the relative angle detection means which detects a relative rotation angle of the rotating body with respect to the reference support; and non-contact angle detection means which detects a rotation angle of the reference support with reference to a position that does not contact with the rotating body and the reference support. This provides improved accuracy in indexing the rotation angle of a rotating moving shaft and easy installation onto the rotating moving shaft.

摘要： There is provided a three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. A groove is formed along a Y-axis direction in a right side part of a surface plate made of stone, and a Y guide is formed between the groove and a right side surface of the surface plate to support a Y carriage in a portal shape in a movable manner in the Y-axis direction. A support section is provided at a lower end of a right Y carriage on the right side of the Y carriage, and the support section is supported by the surface plate through air pads which are disposed by two air pads back and forth on the corresponding one of a top surface, a right side surface, and a bottom surface, of the surface plate, and a right side surface of the groove.
