The length measuring jig includes a rod to be inserted into the central hole in the stud bolt, a first jaw provided on a tip end of the rod for abutting against an end face of the one side in longitudinal direction of the stud bolt, a slider on which the rod is slidably supported, a second jaw provided on the slider for abutting against an end face of the other side in longitudinal direction of the stud bolt, and a cap to be fitted in the central hole in the stud bolt and having a slit defined therein for allowing the rod to extend therethrough. The first jaw has an overall length smaller than a diameter of a minimum-diameter portion of the central hole in the stud bolt. The cap has an inner wall surface defining an end of the slit in the cap, and a distance to the inner wall surface from a central axis of the stud bolt is equal to a radius of the minimum-diameter portion of the central hole in a state in which the cap is fitted in the central hole in the stud bolt.

The present invention provides a mounting apparatus and a parallelism detection method in the mounting apparatus. The parallelism detection method in the mounting apparatus includes: a first height detection process of detecting first heights of a mounting tool when a holding surface comes into contact with the a tip of a triangular pin by placing the triangular pin on a placement surface of a stage and lowering the mounting tool; a second height detection process of detecting second heights of the mounting tool when the tip of the triangular pin comes into contact with the placement surface by holding the triangular pin on the holding surface of the mounting tool and lowering the mounting tool; and a parallelism calculation process of calculating the parallelism between the placement surface of the stage and the holding surface of the mounting tool based on the first heights and the second heights.

The measuring jig for the rotary machine is a measuring jig for a rotary machine including a casing that extending about an axis, a rotor that is disposed in the casing and extends in an axial direction about the axis, and a plurality of bearings that are disposed at intervals in the axial direction and supports the rotor in the casing. The measuring jig includes a plurality of casing fixing portions that are respectively attachable to and detachable from bearing holding portions to which the bearings are attached in the casing; a main member that extends in the axial direction so as to connect the plurality of casing fixing portions to each other; an arm that extends from the main member in an orthogonal direction orthogonal to the axial direction; and a reference surface that is disposed at a distance from a measurement target part of the casing.

The present invention provides a measurement device for grinding wheel. One or more thickness measurement device is disposed slidably on a platform. A spinning device is disposed on the platform. A grinding wheel is fixed on the spinning device. The spinning shaft spins the grinding wheel. The one or more thickness measurement device measures the flatness condition of the grinding wheel. Furthermore, according to the present invention, a diameter measurement device is disposed inside the platform and measures the roundness of the outer periphery of the grinding wheel. Since the structure can be disassembled easily, the whole measurement device for grinding wheel can be carried conveniently. In addition, measurements can be performed by users on the site where the grinding wheel is located for real-timely understanding the real size and wear condition of grinding wheel.

An apparatus for measuring a dimension of a freight item. The apparatus includes an elongate gauge member having a sequence of machine-readable codes visible along its length. Each of the machine-readable codes represents a length value corresponding to a position along the gauge member. The apparatus also includes a marker device, movable along the gauge member, for designating a selected position. The marker device includes a machine-readable reference symbol on an external surface thereof, with the reference symbol being located on the marker device such that in use the reference symbol on the marker device and a subset of the machine-readable codes on the gauge member are simultaneously visible. In a preferred embodiment the elongate gauge member includes a coilable tape and the marker device includes a housing within which the coilable tape is enclosed. A system including the measuring apparatus together with a mobile computing device is also disclosed.

According to some aspects, techniques for determining a position of a build platform in an additive fabrication device are provided. According to some embodiments, forces resisting separation of the build platform from an opposing surface are measured and a position of the build platform with respect to the opposing surface is determined. In some embodiments, such forces may include fluid forces present during separation of a build platform from an interior surface of a liquid photopolymer container.

According to an embodiment, an inspection method inspects a disk drive suspension including an electronic component having first and second side surfaces in a first direction, a first and second adhesives provided along the side surfaces. The method includes measuring a first height in a first position of the first adhesive, measuring a second height in a second position of the second adhesive, and determining whether at least one of a position of application of the first and second adhesives in the first direction and an amount of application of the first and second adhesives is appropriate based on the first and second heights.

The present invention relates to a measuring device for determining the height of a crimp in a crimp connector to a conductor, such as in a cable lug or ferrule. The Exmore CRIMPING MEASURING DEVICE is a crimp height and crimp width measuring system, developed for highly precise measuring of crimp contacts.

The invention is characterized by changes in the blade as used in a micro-metric measuring device. The measuring device according to the invention comprises a measuring knife comprising a resilient tool, further comprising a plate-shaped tool which is placed centrally in the measuring knife and which is placed perpendicularly to the orientation of the measuring knife. Measurement is performed manually and independent of any operator-related influences by way of centering unit. The Exmore CRIMPING MEASURING DEVICE simplifies the crimp height measurement process resulting in faster measurement time and improved consistency, acquired measured values can be read off, transferred via the serial interface or optionally printed.

A hardboard installation support apparatus for mounting hardboard for board and batten siding installations includes a support bracket having a bracket front side, a bracket back side, a bracket top edge, a bracket bottom edge, a bracket left edge, and a bracket right edge. The supper bracket has a pair of mounting apertures extending from the bracket front side through the bracket back side. The pair of mounting apertures receives hardware to engage a building. A measurement indicator is coupled to the bracket front side and indicates a vertical distance from the bracket bottom edge. A support lip is coupled to the support bracket.

In some embodiments, apparatuses and methods are provided herein useful to quickly and accurately determine shelf notch height for a shelving unit. This is particularly advantageous to determine whether shelves in the shelving unit were installed at the correct height and/or for installing shelves at desired heights. In some embodiments, a measurement member is provided with a bottom offset and shelf notch indicator portions. A horizontal position indicator can then be aligned with a desired shelf notch indicator portion and project outwardly therefrom towards a shelving unit to provide a visual indication of the height of a desired shelf notch.
