Abstract: A sheet feeding apparatus comprises a conveying path formed between an upper and a lower units facing each other; a feed roller which feeds a sheet by a portion partially exposed from an upper surface of the lower unit to the conveying path; a separation member disposed to oppose the feed roller; a stopper which stops entrance of the sheet into the conveying path by abutting against a sheet end in a closed state in which the stopper is moved in a direction to intersect with an exposed surface of the feed roller; a driving unit which drives at least the feed roller and the stopper; and a control unit which controls the driving unit to rotate the feed roller through a predetermined angle in a sheet feeding direction and to then open the stopper when feeding of the sheet is started from the closed state of the stopper.

Abstract: A clearance is set between a nail feeder and an outer profile portion so that the nail feeder can turn. A pin as a first restriction member that inhibits movement of the nail feeder to an ejection portion by engaging with the nail feeder and can release the engagement with the rotation of the nail feeder is provided to the outer profile portion. The position at which the nail feeder and a spring engage is set in deviation from the position at which the nail feeder and the pin engage, in a reciprocating direction of the nail feeder and in a vertical direction.

Abstract: The nailing machine (1) comprises an air passage (510) allowing communication between a cylinder (200) and a return air chamber (500) in which compressed air for returning a piston (300) to the initial position is accumulated. The air passage (510) is provided with a control valve (520) controlling entry of compressed air into the return air chamber (500) from the cylinder (200). The control valve (520) opens the air passage 510 and allows entry of compressed air into the return air chamber (500) in the case wherein the nailed object produces a small reaction force upon driving the nail, namely when the upward moving distance of the body (100) relative to the push lever (700) is smaller than a predetermined distance. The compressed air that has entered the return air chamber (500) further enters a below-the-piston chamber and serves as air damper, reducing excess energy absorbed by a piston bumper (360).

Abstract: The magnitude of an amplitude waveform of an electromagnetic wave generated when irradiating a pulse laser beam to a structure A including diffusion regions provided in the structure of a semiconductor device to be inspected is compared with the magnitude of an amplitude waveform of an electromagnetic wave radiated when irradiating the pulse laser beam to a structure A of a reference device measured in advance, and the detection sensitivity of the electromagnetic wave is corrected (S14). Thereafter, measurement errors caused by variations in the detection sensitivity of electromagnetic waves of an inspecting apparatus are eliminated by inspecting the semiconductor device as an inspection target, so that the quality of the semiconductor device is precisely determined (S16).
