Abstract: A driving tool is provided with a driver for driving out a fastener from a nozzle, a balancer, and a balancer biasing member for biasing the balancer in a direction away from the nozzle. The balancer moves in the direction away from the nozzle by a biasing force of the balancer biasing member when the driver moves toward the nozzle.

Abstract: A striking tool includes: a striking mechanism configured to strike a fastener into a member to be struck; a motor configured to drive the striking mechanism; and a clutch provided between the striking mechanism and the motor and configured to switch transmission and interruption of a drive force of the motor to the striking mechanism.

Abstract: A driving tool is configured to drive fasteners shot from an ejection port into a driving target. The driving tool includes a trigger configured to carry out a driving action, a nose part formed with the ejection port, a contact member provided to be slidable relative to the nose part and is capable of being pressed against the driving target, and a contact detecting part configured to detect that the contact member is pressed against the driving target. The driving action is carried out when the contact detecting part detects that the contact member is pressed against the driving target and when the trigger is operated. The contact member is slidable to a side opposite to and beyond a tip of the nose part.

Abstract: The present invention relates to a method for producing a polyolefin porous film, the method including the steps of: (a) melt-kneading a solution containing a polyolefin having a weight average molecular weight of 500,000 or more and a solvent to obtain a kneaded product; (b) extruding and cooling the kneaded product to obtain a gel-like molded product; (c) drawing the gel-like molded product to obtain a drawn sheet; (d) removing the solvent from the drawn sheet, followed by drying to obtain a film in which fine pores are formed; (e) conducting heat treatment, while fixing the film in both directions of a MD and a TD thereof and drawing the film at a draw ratio of exceeding 0% to less than 0.1% in at least one direction of the MD and the TD thereof; and (f) conducting heat treatment while decreasing a width of the film in at least one direction of the MD and the TD of the film.

Abstract: A wired-circuit-board-assembly sheet includes a plurality of wired circuit boards arranged in parallel in one direction, which are regularly omitted at given intervals, and a plurality of units defined by margin portions where the wired circuit boards are omitted.

Abstract: A spiral wound type membrane element is formed by superposing gas-liquid contact membranes on both surfaces of a first fluid passage forming member, superposing a second fluid passage forming member on the surface of one of the gas-liquid contact membranes and spirally winding the gas-liquid contact membranes around a second fluid supply pipe along with the first fluid passage forming member and the second fluid passage forming member. A side portion on the inner peripheral side and a side portion on the outer peripheral side of a first fluid passage formed by the first fluid passage forming member between the gas-liquid contact membranes are sealed. Both end portions of a second fluid passage formed by the second fluid passage forming member between the gas-liquid contact membranes are sealed. The spiral wound type membrane element is stored inside a cylindrical container. The gas-liquid contact membranes are formed by PTFE (polytetrafluoroethylene) porous membranes having hydrophobicity.
