摘要:
Components of a measuring tool such as a main beam (11) and a slider (12) of a caliper gauge (1) are formed by a synthetic resin containing carbon nanofiber and an electro-conductive electrode (15) is formed on the surface of the main beam (11) at a predetermined pitch, so that a production process can be simplified, rigidity of the components can be enhanced, linear expansion coefficient can be reduced, and anti-frictional properties can be improved, thus enhancing durability while improving measurement accuracy.

摘要:
A coordinates measuring head unit is provided, which is compact, inexpensive, and capable of performing high-precision measurements at high speeds, and facilitates, for example, measurements conducted on machine tools or in-situ measurements on transport lines. The head unit includes: drive means (an X-axis drive section, a Y-axis drive section, and a Z-axis drive section), an integrated housing for accommodating the drive means, and fixture means (fixture surface). The drive means allows a probe to be moved by computer numerical control along a plurality of drive axis, which are orthogonal to each other, and abut against a measuring target to measure the dimensions of the measuring target. The fixture means is provided on one of side surfaces of the housing to attach one of the drive means to a support (a support on a stand secured to a base).

A form measuring sensor (33) includes a stylus (40), a body (60) for holding the stylus (40) through an adaptor (50), the adaptor (50) including a stylus attachment (51) for the stylus (40) to be attached, a body attachment (52) to be attached to the body (60), and an elastically deformable connector (53) for connecting the stylus attachment (51) and the body attachment (52), where the sensor (33) and a threaded hole (100) are relatively moved to cause an elastic deformation of the connector (53) allowing a displacement of the stylus (40) in accordance with surface configuration of the threaded hole (100), so that the elastic deformation of the connector (53) is detected by a strain gauge (71) to detect the displacement of a contact portion (42A) to collect continuous configuration data of the threaded hole (100) within a short period of time.
摘要:
An automatic inner diameter measuring apparatus which includes an inner diameter measuring gauge head having at least one contacting element capable of being inserted into bores of an object to be measured and moving in a radial direction of the bore. A stocker is provided which is capable of holding a plurality of inner diameter measuring gauge heads corresponding to different diameters. A three-dimensional moving instrument is provided for detachable coupling with the inner diameter measuring gauge head to facilitate a three-dimensional movement with reference to the object to be measured and the inner diameter measuring gauge. A drive device for the three-dimensional moving instrument is provided. A plurality of master ring gauges supported on a ring gauge support are provided to set an inner diameter measuring gauge head attached thereto to zero.
摘要:
A height gage having a cylindrical column supporting a slider vertically movably thereon.The slider vertically movable to the column is restricted from rotation by a scale vertically extended along the column and the slider is connected by way of string members to a balance weight provided in the column so as to facilitate the slider operation. Air jetting ports are formed to the bottom surface of a base having the column erected upright thereon, so as to form a pneumatic bearing between the base and the substrate for mounting the height gage to facilitate gage movement.
摘要:
In a reactor for cracking heavy hydrocarbon oil through a fluidized bed of the particles of natural ores, coke-like materials are deposited on a top of the reactor or pipe inside surfaces of a transfer line from the reactor to a scrubber. To effectively scour out the deposited coke-like materials, particles of natural ores having a mean diameter of a few hundred .mu.m is made to be contained in an effluent gas from the top of reactor, passing through the transfer line at a concentration of 1 to 40 g/m.sup.3. The particles of natural ores have a good effect of scouring out the deposited coke-like materials and can keep the transfer line efficiently clean even with a small amount of the particles of natural ores, decreasing a pressure drop in the transfer line.
