Abstract: An image forming apparatus has a liquid discharge head to discharge droplets of a recording liquid to form an image on a recording medium and a maintenance-and-recovery mechanism to perform a maintenance and recovery operation on the liquid discharge head. The maintenance-and-recovery mechanism includes a suction device, a control unit, a drain tube, and a drain reservoir. The suction device suctions droplets of the recording liquid from the liquid discharge head. The suctioned droplets are not used for an image forming operation. The control unit controls a suction speed of the suction device. The drain reservoir stores the suctioned droplets drained from the drain tube. The drain tube is inclined relative to an opening portion of the drain reservoir. The control unit controls the suction speed of the suction device to change a drain speed of the suctioned droplets drained from the drain tube.

Abstract: An apparatus for chamfering the outer edges of stacked printed circuit boards comprises a detecting device for detecting the boundary between two adjacent boards, and a chamfering tool positionable adjacent to the opposed outer edges of respective ones of the two adjacent boards in response to detection of the boundary and movable along the board outer edges to simultaneously chamfer both outer edges. The chamfering tool successively chamfers pairs of opposed outer edges in the upward direction on one side of the stack, and then the stack is turned so that the chamfering tool chamfers the outer edges on a different side of the stack printed circuit boards.

Abstract: A planar surface of an article is ground smooth by a two-stage grinding head having an upstream-stage grinding brush and a downstream-stage grinding stone. The article is advanced past the grinding head while the grinding head is eccentrically driven so that the grinding brush coarsely grinds the planar surface and forms therein spiral brush traces and the grinding stone finely grinds the coarsely ground planar surface to smoothen the brush traces.

Abstract: A liquid discharge head includes a nozzle plate having a nozzle from which a liquid is discharged, a housing holding the nozzle plate, a valve that opens and closes the nozzle, an expandable driver disposed inside the housing, and a restraint. The expandable driver has a first end that supports a rear end of the valve and a second end fixed to the housing. The expendable driver moves the valve in a longitudinal direction to push a leading end of the valve against the nozzle to close the nozzle. The restraint positions the second end with respect to the housing in the longitudinal direction. A difference between ΔL1 and ΔL2 is equal to or less than a predetermined value, where ΔL1 represents a thermal deformation amount of a first length due to temperature change, and ΔL2 represents a thermal deformation amount of a second length due to the temperature change.
