The robot hand includes a plurality of holding parts provided to be holdable of a plurality of workpieces, respectively, and a pneumatic drive for protruding one of the holding parts, when the holding part holds one of the workpieces, toward the workpiece with respect to one or more remaining holding parts by pneumatic pressure.

Abstract: A robot hand and a robot according to an embodiment include a set of sliding parts, supporting units, a rotary unit, and a plurality of holding claws. The sliding parts slide in a direction to come close to or move away from each other. The supporting units are secured to the respective sliding parts. The rotary unit is attached to an end portion of at least one of the supporting units and rotates around an axis of rotation parallel to sliding shafts of the sliding parts. The holding claws are attached in directions orthogonal to the axis of rotation and different from one another.

Abstract: A hand according to an embodiment includes a pair of supporting units, a pair of capturing claws, an opening-and-closing mechanism, and a reciprocating mechanism. The pair of capturing claws are supported on the inner surfaces of the pair of respective supporting units and capture a part. The opening-and-closing mechanism opens and closes the pair of supporting units along a reciprocating axis intersecting with longitudinal directions of the supporting units. The reciprocating mechanism causes the pair of capturing claws to rotate about the reciprocating axis to change the direction of each tip of the capturing claws.

Abstract: A robot system according to an aspect of an embodiment includes a supply unit and a robot. The supply unit is fixedly provided at a predetermined position to supply a feed material that is used for processing a workpiece. The robot transfers the unprocessed workpiece handed from an operator at a predetermined transfer position to the vicinity of the supply unit to process the workpiece by using the feed material supplied from the supply unit and then transfers the processed workpiece to the transfer position.

Abstract: A substrate holding apparatus includes a base plate with a two-pronged portion, a holding plate arranged above the base plate, a driving portion provided therebetween, a holding portion formed by a tip end of the two-pronged portion and a tip end of the holding plate, and a guide portion provided at the tip end of the two-pronged portion for guiding a part of the substrate. The driving portion includes an urging means for always urging a basal end side of the holding plate upward, an electric magnetic portion for drawing the holding plate toward the base plate, and a bearing portion arranged at on the tip end side of the base plate. The guide portion has a guide groove which comes into contact with a part of a periphery of the substrate.

Abstract: A shield case includes first and second side plates formed by blanking a metal sheet. Between the first side plate and the second side plate, two shield plates are formed connected to the side plates through connecting portions. One shield plate has, in one end edge, a protuberance and, in the other end edge, a shield plate formed through a connecting portion. Bending allowances are formed respectively in the first and second side plate in areas between the connecting portions. During assembling, the bending allowances of the first and second side plates are bent inward between the shield plates.

Abstract: A hood or trunk lid is a blow-molded article and includes an outer skin and a stiffener integral with the outer skin. The stiffener has a tub-like molded portion which extends in a widthwise direction of a vehicle body and protrudes toward the outer skin. A ridge of the tub-like molded portion is spaced apart from the outer skin, so that the hood or trunk lid is folded from a start point provided by the tub-like molded portion by a shock force from a collision.

Abstract: A method of lubricating a metal working machine which has (i) at least one sliding machine surface requiring lubrication and (ii) a metal working section wherein metal is worked in contact with a metal working fluid, said method comprises applying a lubricating oil composition to said at least one sliding surface and using as said metal working fluid an aqueous working fluid composition comprising said lubricating oil composition diluted with water, the ratio of water to said lubricating oil composition being at least 3 to 1,said lubricating oil composition comprising:(A) 10 to 90% by weight of at least one oil selected from the group consisting of a mineral oil and a synthetic oil,(B) 0 to 30% by weight of at least one extreme pressure additive selected from the group consisting of sulfurized fat and oil, a phosphate, a phosphite, and an amine salt of phosphate or phosphite and(C) 10 to 60% by weight of an emulsifying agent selected from the group consisting of an anionic surface active agent, a cationic sur
