The portable apparatus for cleaning surfaces comprises a tank (2) associated with a base (3), said tank (2) comprising at least one couple of chambers (5) predisposed to contain respective abrasive materials, said chambers (5) being hermetically separated from one another; at least one couple of mixing valves (13) associated with said base (3) and connected with respective said chambers (5) each said mixing valve (13) being predisposed to receive said abrasive material contained in said respective chamber (5) and to mix said abrasive material with a predetermined amount of compressed air.

The invention is directed toward wet-abrasive blasting systems used for cleaning, preparing surfaces, removing coatings, and other abrasive blasting applications. The wet abrasive basting system has a blast pot that includes a venting system. The venting system may be a self-venting system that allows gases to be vented during charging and prevents gases from accumulating in the blast pot during operation. In wet abrasive blasting systems a slurry is conveyed via a piping system, hoses, etc. to a mixer connected to a source of pressurized gas where slurry and compressed air/gas are combined and directed through the blast hose and blast nozzle.

A deburring device includes a deburring tool for removing burrs from an object, a robot for moving an object or the tool, a force sensor for detecting force acting on the tool, and a visual sensor for detecting a position of a burr portion of the object. According to the deburring device, information regarding shape data of the burr portion and a posture of the tool is obtained beforehand based on three-dimensional data of the object. Based on the shape data and the posture of the tool, a robot program is created. In accordance with an actual burr portion detected by the visual sensor, the robot program is replaced as necessary. During the deburring, the robot is controlled according to the force control by using a detected value from the force sensor.

A wet abrasive blasting system includes a vessel having multiple outlets for dispensing slurry. A first sprayer of the system is operatively associated with a first blast control switch, and a second sprayer is operatively associated with an n-th blast control switch. A first blast line fluidly connecting the first sprayer to the first outlet includes a first pinch valve, and an n-th blast line fluidly connecting the n-th sprayer to the n-th outlet includes an n-th pinch valve. A time delay module of the system transmits signals to close all system pinch valves upon receipt of signals indicative of an actuated state of more than one blast control switch and, after a predetermined time delay, transmits signals to open all system pinch valves associated with their respective actuated blast control switches.

A method of making a printed circuit board includes a step of providing a double-sided plate that is an insulating substrate having conductive layers on respective surfaces thereof, a first coating step of coating a first surface of the double-sided plate with a first photosensitive resin film, a second coating step of coating a second surface of the double-sided plate with a second photosensitive resin film, a first exposure step of exposing the photosensitive resin film coating the first surface after the first and second coating steps, and a second exposure step of exposing the photosensitive resin film coating the second surface after the first exposure step, wherein a maximum depth of a depression in an outermost surface of the second photosensitive resin film used in the second exposure step is less than 1.0 μm.

A shot processing apparatus is equipped with a work set jig, a hanger transport device, a projection machine, a projection positioning unit and a clamp unit. The work set jig is equipped with a base member including an upper and lower pair of cross members and a vertical member. A workpiece is settable at the base member between the upper and lower pair of cross members. The hanger transport device is, with the work set jig in a hanging state, movable along a guide path in the shot processing apparatus and is capable of stopping thereon. The projection machine projects projection media at a workpiece set at the base member inside a projection chamber which the workpiece is conveyed into. The projection positioning unit positions the work set jig at a stopping position in the projection chamber. The clamp unit fixes a workpiece between the upper and lower pair of cross members.
