Abstract:
To provide a tactile sensor that allows a contact to be displaced largely and can detect fine ruggedness, flexibility, and other features of a surface of a measuring object. A sensor part S includes a frame 10 that includes a side part of a substrate B, a contact 20 that is disposed in parallel to the substrate B so that a tip of the contact 20 projects from a side face of the substrate B, a suspension 30 that supports the contact 20 to the frame 10, and displacement detectors 41 and 42 each of which detects displacement of the contact 20. The side face of the substrate B functions as a sensing surface. The contact 20 coming in contact with a measuring object O is displaced on a level parallel to the substrate B. Since the sensor part S can be configured widely in a planar manner along the substrate B, the structure has higher flexibility of design. As a result, the sensor part S allows the contact 20 to be displaced largely, and can detect fine ruggedness, flexibility and other features of the surface of the measuring object O.
Abstract:
The present invention has a first object to efficiently use data acquired by roundness measurement for surface roughness measurement to reduce a measurement workload and improve measurement efficiency and the like, and a second object to not only improve measurement efficiency of roundness measurement and surface roughness measurement, but also mutually use data acquired by each of the roundness measurement and the surface roughness measurement for roundness measurement data and surface roughness measurement data to improve measurement accuracy, for example. To achieve the first object, measurement conditions in surface roughness measurement are set on the basis of data on a measuring object acquired by roundness measurement. To achieve the second object, there are provide a first measurement unit that performs roundness measurement of the measuring object, and a second measurement unit that performs surface roughness measurement of measuring object at a position opposite to the first measurement unit in the circumferential direction, and the roundness measurement by the first measurement unit and the surface roughness measurement by the second measurement unit are simultaneously performed.
Abstract:
A method of evaluating the smoothness of a topsheet or a backsheet of a disposable absorbent article is disclosed, the method comprising: - providing an element having a surface, - providing a first disposable absorbent article having a topsheet, a backsheet, and an absorbent core located between the topsheet and the backsheet, - rubbing the surface of the element against the topsheet or the backsheet of the disposable absorbent article along a predetermined length of the disposable absorbent article with a predetermined force, - inspecting the surface of the element after it has been rubbed to evaluate if the surface of the element or the topsheet or the backsheet of the disposable absorbent article is damaged or destroyed by the rubbing against the topsheet or the backsheet of the disposable absorbent article.
Abstract:
Multidirectional roughness measuring insert for determining a measurement variable characteristic of the roughness of a surface, comprising a carrier body, on which a stylus holder for holding a stylus is arranged, an analogue sensor which converts movements of the carrier body into measurement signals characteristic of the roughness of a surface of a workpiece, a stylus which can be coupled to the carrier body and which comprises a rod-shaped shaft and a stylus head attached to the shaft, wherein the stylus head is at least a portion of a substantially disc-shaped test body that is substantially rotationally symmetrical at least in relation to a portion of the rod-shaped shaft, or wherein the stylus head is at least a portion of a substantially rotationally symmetrical and substantially disc-shaped test body which is arranged at a distal end of at least of a portion of the rod-shaped shaft.
