A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.

To detect whether barrel lids are fixed.

A centrifugal barrel polishing machine (A) includes: a plurality of rotary tanks (50) that rotate planetarily; barrel lids (26) that are attachable to and detachable from the rotary tanks (50); and a plurality of clamp shafts (32) that are provided individually in the plurality of rotary tanks (50) so as to be rotatable integrally with the rotary tanks (50). Each of the clamp shafts (32) is displaceable between in a fixing form for fixing the barrel lid (26) to the rotary tank (50) and in a releasing form for releasing the fixation of the barrel lid (26). It is detected by a first detection means (40) whether the rotary tank (50) is positioned in a detection area (D) on a revolution path of the rotary tank (50), and it is detected by a second detection means (43) whether the clamp shaft (32) of the rotary tank (50) positioned in the detection area (D) is displaced to the fixing form.

A process system of performing a fabrication process on a wafer includes a wafer storage cassette, one or more process chambers, a transfer chamber having a body and a lid that detachably covers the body, and a locking pin. The transfer chamber also includes a robot hub, a robot arm attached to the robot hub, and a blade attached to the robot arm. The body of the transfer chamber is connected to the wafer storage cassette and the process chambers, and the robot arm is configured to transfer a wafer from the wafer storage cassette through the body of the transfer chamber to one or more of the process chambers. The locking pin is configured to detachably attach to the robot arm to constrain the blade at a predetermined position within the transfer chamber.

A system includes a power tool and an automatic safety system communicatively coupled to the power tool. The automatic safety system includes one or more sensors disposed about the power tool, where the one or more sensors are configured to gather data about a safety parameter related to an operation of the power tool. The automatic safety system also includes a main detector configured to receive the data gathered by the one or more sensors. The main detector is configured to analyze the received data to determine whether to unlock the power tool for operation.

An accuracy of detecting a slip out of a substrate from a top ring is improved. A polishing unit 300 includes a polishing table 350, a top ring 302, a light emitting member 371, a slip-out detector 370, and an elimination mechanism 380. A polishing pad 352 that polishes a substrate WF is attached to the polishing table 350. The top ring 302 holds the substrate WF to press the substrate WF against the polishing pad 352. The light emitting member 371 emits a light to a detection area 372 on the polishing pad 352. The slip-out detector 370 detects a slip out of the substrate WF from the top ring 302 based on the light reflected from the detection area 372. The elimination mechanism 380 eliminates a polishing liquid flowing into the detection area 372.

An illuminating drywall sponge device provides a drywall sanding/scraping tool having tapered cavities that securely retain an illumination mechanism, such that the work surface being sanded is illuminated during sanding operations; and a marking mechanism for marking the illuminated work surface. The sponge light device provides a housing through which the sanding function is primarily performed. The housing has a block or rectangular shape, and walls with an abrasive material. The housing also has multiple tapered cavities formed at the walls of the housing, oriented coplanar with the surface being sanded. An illumination mechanism fits into the cavity. The illumination mechanism orients in the cavity to throw light outwardly from the edge of the housing. A grommet fits into the outer region of the cavities to help stabilize and fasten the illumination mechanism in the cavities. A retractable marking mechanism may also insert into the cavity.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.
