A measuring apparatus is provided comprising: a stage, including three or more pads formed on a surface of the stage, the pads forming an invisible plane and capable of supporting a panel to be measured; a movable measuring stylus, having a tip, the measuring stylus being movable between an initial position, through an insertion region, and a measuring position; a spring, the spring being disposed to apply downward force upon the measuring stylus so that the measuring stylus presses against the ...

A measuring apparatus includes a heating unit for applying heat to a first point within a workpiece or on a surface of a workpiece and propagating the heat to a second point within the workpiece or on the surface of the workpiece. The measuring apparatus further includes a measuring unit for measuring a displacement of the surface of the workpiece at the second point to which the heat has been propagated, and an analyzing unit for analyzing a structure of the workpiece based on the displacement ...

A measuring apparatus for measuring the state of attenuated total reflection over time for a single measuring unit without being affected by the change in measuring conditions arising from replacement and resetting of the sample. A light beam is entered into the interface between a dielectric block and a metal film having a dielectric film thereon at various incident angles within the angle range that creates two or more dark lines due to attenuated total reflections, and the variation in the po...

A method is provided for measuring the wall thickness of transparent articles using non-collimated and diverging light in the form of a small point source or elongated narrow line of light, measuring the spacial separation of the reflections from the nearest and furthest surface by means of a two-dimensional image sensor and a computational device to calculate the geometrical corrections needed to provide accurate thickness measurements. In situations where smooth thickness variations occur, a s...

Apparatus for measurement concerning fluids in a rotor or container (2) during rotation, comprising an electric or magnetic sensor (4) mounted internally on a wall in the container (2), and means (5A, 5B) for contact-free and intermittent transmission of measurement signals from the sensor (4) to a stationary measuring unit (7) outside the container. The sensor (4) comprises an active electronic circuit (8) adapted to store measurement values that are recorded during at least a portion of a revo...

A length measuring device. The device comprises a length measuring portion and a measuring portion housing. Measurement recording means is provided on at least a portion of the housing surface.

While a ball 14 is inserted into a hole WA of a workpiece W and is moved in the longitudinal direction of the hole WA while automatically centripetally moved, a change of back pressure of a gas injected into the hole WA is detected by a converter 30, and at the same time reflected light from a reflection member 18 provided on the ball 14 is received by a light receiving unit 22 and a change of peak position A of an amount of the received light is calculated, so as to calculate an inner diameter,...

A measuring transducer with a sensor for converting a detected measured value into a sensor signal. The sensor signal is processed in a signal processing device to form a measuring signal that is transmitted to a central location via a data interface. The data interface is also used as a conduit for signals to parameterize the measuring transducer. The measuring transducer includes a device that provides a simulated measuring signal that can be transmitted to the central location on request via ...

A unit damper apparatus 18 is used as a damper apparatus 18 which absorbs an impact and a vibration conveyed from a contact 14 to a seesaw member 12, and a structure of this unit damper apparatus 18 is the structure which absorbs circular movement of the seesaw member 12 or performs the circular movement in accordance with that of the seesaw member 12, where a damper effect does not fluctuate according to an angle of inclination of the seesaw member 12.

The image of a tool center point (31) caught by a camera (light-receiving device) 4 from two initial positions is moved to a predetermined point, by a predetermined point moving process, at the center of a light-receiving surface thereby to acquire robot positions (Qf1, Qf2), based on which the direction of the view line (40) is determined. Next, the robot is moved to the position where the position (Qf1) is rotated by 180 degrees around the Z axis of a coordinate system (.SIGMA.v1) thereby to e...
