摘要： With the Z-axis given as a central axis, on an XY-plane, arranged are a rigid force receiving ring, a flexible detection ring inside thereof, and a cylindrical fixed assistant body further inside thereof. Two fixing points on the detection ring are fixed to a supporting substrate, and two exertion points are connected to the force receiving ring via connection members. When force and moment are exerted on the force receiving ring, with the supporting substrate fixed, the detection ring undergoes elastic deformation. Capacitance elements or others are used to measure distances between measurement points and the fixed assistant body and distances between the measurement points and the supporting substrate. Elastic deformation of the detection ring is recognized for mode and magnitude, thereby detecting a direction and magnitude of force or moment which is exerted.

摘要： A small, high-stiffness torque sensor. An annular deformable body is disposed between left and right side supports. Convex sections protruding from the left side support in a rightward direction are joined to the left side surface of the annular deformable body, and convex sections protruding from the right side support in a leftward direction are joined to the right side surface of the annular deformable body. When force is applied to the right side support and torque around the Z axis acts on the left side support, the annular deformable body is elliptically deformed and the long-axis position of the inner peripheral surface of the annular deformable body moves away from the Z axis while the short-axis position moves closer to the Z axis. The acting torque is detected as a variation in the capacitance value of capacitive elements formed by displacement electrodes and fixed electrodes.

摘要： A reseat system capable of restraining reseat shift in returning from escape movement and thus capable of obtaining reseat return accuracy without adding separate mechanism is provided. A locus drawn by a tip of a stylus when the stylus moves parallel to an axis thereof at a rest position while a hard ball on a fixed component is in contact with a cylindrical body on a movable-component having the stylus is inclined in a direction of a biasing force. When a pressing force is applied to the movable component, since a reaction force against the pressing force is generated at a contact point of the cylindrical body and the hard ball, reseat shift of the movable component can be restrained.

摘要： An interference optical system (1) is employed to split an input light beam in two, giving a predetermined optical path length difference to the resultant two light beams and thereafter synthesizing them to generate interference fringes. A reference light with a known wavelength &lgr;1 is introduced into the interference optical system (1) from a coherent reference light source (2). A test light with an unknown wavelength &lgr;2 is simultaneously introduced into the interference optical system (1) from a coherent test light source (3) via a different optical path. The interference optical system (1) modulates both received signals obtained from the reference and test lights by giving the same variation to optical path length differences for the reference and test lights. Degrees of modulations of the received signals, obtained from the reference and test lights, depend on their wavelengths &lgr;1 and &lgr;2, respectively. Accordingly, the wavelength &lgr;2 of the test light can be computed by detecting the degrees of modulations of the received signals and using a ratio between the degrees of the wavelength &lgr;1 of the reference light.

摘要： In a touch signal probe (10) having a stylus holder (11), a vibrator (12) supported by the stylus holder (11) and has a contact portion (12A) to contact to a workpiece at a distal end thereof, a vibrating means (13A) for vibrating the vibrator (12) in an axial direction resonantly, and a detecting means (13B) for detecting the contact by a change in the vibration of the vibrator (12) caused by the contact to the workpiece is provided. The vibrator (12) is supported by the stylus holder (11) at two support points (A) and (B) positioned with a node of vibration of the vibrator (12) therebetween. Since the vibrating means (13A) and the detecting means (13B) are disposed spanning over the two support points, the node of vibration can be formed between the support points A and B and the size of the touch signal probe (10) can be easily reduced.

摘要： A vibration change is detected by a touch signal probe having a vibrator (16) composed of a stylus support (10) and a stylus (13) attached thereto, and a vibrating/detecting means (12) provided to the stylus support (10) for applying vibration to the vibrator (16) and detecting a vibration condition changing when the stylus (13) touches a workpiece. The vibrator (16) is vibrated at a frequency equivalent to secondary intrinsic frequency (w2) to make resonance and the vibration change is detected by superposing a vibration component of primary intrinsic frequency (w1). Though the vibration at the secondary intrinsic frequency (w2) has high Q value, response amplitude is small. Accordingly, the vibration change is amplified by superposing the vibration component of the primary intrinsic frequency (w1).
