A height measuring apparatus comprising a main body portion adapted for placement upon an object to be measured, and a movable portion which is movable relative to the main body portion, wherein the movable portion comprises a laser source and a photo detector, the movable portion being movable so that a laser beam from the laser source can be directed to the ground when the main body is placed on the object to be measured.

An adjusting mechanism of a sample holder is provided. The adjusting mechanism includes a base with drives arranged thereon, and a carrier that is adjustable by means of the drives and is designed to receive the sample holder. A coupling element for each drive, which coupling element is designed to connect the base and the carrier. Each coupling element has at least one linear degree of freedom and also a rotary degree of freedom. The carrier is linearly movable, by means of the coupling elements, along a respective movement axis directed from the coupling element to the carrier. Also provided is a microscope that includes such an adjusting mechanism, along with a method for adjusting the orientation of a sample holder).

A display panel bonding device and a correction apparatus and method thereof. The correction apparatus includes: a fixture assembly including a first fixture and a second fixture coordinating with each other. The first fixture is provided with a first alignment mark, the second fixture is provided with a second alignment mark, and alignment between the first fixture and the second fixture is achieved via the first alignment mark and the second alignment mark; and an image acquisition assembly configured to acquire a first image of the first alignment mark of the first fixture and a second image of the second alignment mark of the second fixture respectively. The first image and the second image are used for acquiring an alignment parameter of the first alignment mark and the second alignment mark to correct alignment between the first fixture and the second fixture.

A rotary disk rotatable around a vertical rotation axis; a bearing supporting the rotary disk so as to be freely rotatable; a slide disk slidable on a top surface of the rotary disk; a position adjustment bracket that displaces the slide disk along the top surface of the rotary disk; a placement disk that is supported by the slide disk; a plurality of air nozzles that are arranged on a top surface of the stator in an annular shape centered on the rotation axis, and form a static pressure air film between the top surface of the stator and a bottom surface of the rotary disk; an aerostatic pocket formed between the top surface of the rotary disk and a bottom surface of the slide disk; and a communication aperture is formed on the rotary disk and introduces pressure of the static pressure air film into the aerostatic pocket.

A connecting joint for adjustably connecting at least two components of a laboratory automation system is disclosed. The connecting joint comprises a horizontal bearing unit connectable to a first component of the at least two components of the laboratory automation system; a vertical bearing unit connectable to a second component of the at least two components of the laboratory automation system; and a slider bar connecting the horizontal bearing unit with the vertical bearing unit, wherein the slider bar is movably mounted along a vertical axis within the vertical bearing unit; and wherein the slider bar is adjustably mounted in the horizontal bearing unit, wherein the slider bar is adjustable in at least one dimension essentially perpendicular to the vertical axis by the horizontal bearing unit.

Afforded is a linear stage including first, second, and third supporting parts disposed on a supporting flat surface, a first shaft supported by the first and second supporting parts and extending in a first direction, a second shaft supported by the third supporting part and provided extending in the first direction, and a translating carriage translated in the first direction, guided by the first shaft and the second shaft. At least one supporting part among the first, second, and third supporting parts supports the shaft supported by that supporting part in a way such as to be displaceable in a second direction orthogonal to the first direction and parallel to the supporting flat surface.
