Abstract: Disclosed is a latching mechanism for a high-torque tool that allows a top semicircular segment to be connected and disconnected from a bottom semicircular segment, which allows a hex jaw (reaction gear) to engage a fluid fitting static nut for application of high torques. A pivoted latch has a curved blade, which is mounted closer to the center point of the hex jaw (reaction gear) than the latch pivot pin of the pivoted latch so that all of the forces are absorbed by the curved blade rather than the latch pivot pin.

Abstract: A dual-beam torque wrench with a linear display and a linear locking member is provided. The torque wrench includes a head that couples to a socket to rotate a fastener or bolt. A housing of torque wrench extends from the head to form a handle. Within the housing forming the handle are two beams: a lever beam that transmits the force from the handle to the head and a deflecting beam that couples to the head and not the handle. The deflecting beam deflects away from the lever beam to indicate that a predetermined torque has been applied. A torque adjustment assembly moves the lever beam relative to the head to set the predetermined torque, and a pin follows the linear display to indicate to the user the set predetermined torque.

Abstract: During chemical mechanical polishing of a substrate, a signal value that depends on a thickness of a layer in a measurement spot on a substrate undergoing polishing is determined by a first in-situ monitoring system. An image of at least the measurement spot of the substrate is generated by a second in-situ imaging system. Machine vision processing, e.g., a convolutional neural network, is used to determine a characterizing value for the measurement spot based on the image. Then a measurement value is calculated based on both the characterizing value and the signal value.

Abstract: A method for polishing a diamond crystal includes preparing a diamond crystal having a main surface having a plane orientation of (100). Mechanical polishing is performed on the main surface using a polishing wheel such that: a tangent contacts a curve extending in a rotation direction of the wheel and contacting a contact position between the diamond crystal and the wheel that is rotating; and a tangent direction of the tangent at the contact position is within a range of ±10 degrees relative to a <110> direction of the diamond crystal, thereby causing an affected region to appear such that the affected region is parallel to a direction of a plane orientation (111) of the diamond crystal and penetrates the diamond crystal onto the main surface. Chemical mechanical polishing is performed on the main surface to remove the affected region, thereby removing the affected region from the main surface.

Abstract: Present invention teaches double-sided magnetic cutting deck. A plurality of magnets are used on both sides of a PC center board, sandwiched by an upper and a lower board, and bonded by TPU glue, which is also the same material used on the upper and lower boards. The magnets are substantially the size of the holes, so as to fit snuggly into the holes, with gap spaces between the edges of the hole to hold excess TPU glues, for better bonding of the magnets in place. Using the TPU materials on the surface (of upper and lower boards) provides longer product life due to the good resilience to physical force from the cutting impressions made during normal use.
