Abstract: A robot system is provided, which includes a paint booth, and a pretreatment robot configured to perform painting pretreatment on a workpiece that is an object to be painted, the pretreatment robot being an explosion-proof robot disposed in the paint booth and including an end effector used for the painting pretreatment.

Abstract: A painting robot includes a base, a swivel base, a lower arm, an upper arm, and a wrist unit. The upper arm includes a first upper arm on a base end side and a second upper arm on a tip end side. The second upper arm is supported, on a base end side, by a tip end side of the first upper arm, the first upper arm being supported by the lower arm on an inner surface that is a side surface of the first upper arm, and pivots about a fourth axis parallel to a third axis. The first upper arm is equipped with a pump for an end effector on an inner surface side.

Abstract: To provide a coating diagnosis system and a coating diagnosis method that allow centralized management over data related to processes in a painting line, including a pretreatment process. The coating diagnosis system includes a data acquisition unit of a pretreatment controller that acquires data related to a pretreatment process when pretreatment for paint is performed on a workpiece in the pretreatment process in a painting line, and a data management unit of a host controller that registers the data related to the pretreatment process in a database in associated with a serial number of the workpiece.

Abstract: A robot system includes a workpiece supplier, a work robot, and a support. The workpiece supplier is to turn a workpiece about a workpiece turning axis to position the workpiece at a work position. The work robot includes a base and a robot arm. The robot arm is connected to the base turnably about an arm turning axis to perform a work on the workpiece at the work position. The arm turning axis crosses the workpiece turning axis. The support connects the workpiece supplier and the base.

Abstract: A robot is provided which has: a first arm portion to which an end effector is attached, a second arm portion configured to support, at a tip portion thereof, the first arm portion swingably about a first axis, a third arm portion configured to support a base end portion of the second arm portion rotatably about a second axis orthogonal to the first axis, a tube arranged from the base end portion side toward the tip portion side of the second arm portion and connected to the end effector; and a first recess portion and a second recess portion, which are formed along an arrangement direction of the tube between the base end portion and the tip portion on one side and the other side in a direction orthogonal to both of the first and second axes, respectively.

Abstract: A connector includes a housing, a plurality of contacts, and a restricting member. The contacts are made of a conductive material. Each of the contacts includes a contacting part and a deformed part. The contacting part protrudes from the housing, is adapted to electrically come in contact with another connector, and is displaced in a first direction when contacts the another connecter. The deformed part is accommodated in the housing and is elastically deformed when the contacting part electrically comes in contact with the another connector. The restricting member is provided in the housing, is contacted to the deformed part, and restricts a displacement of the deformed part in a direction opposite to the first direction.

Abstract: A rubber composition comprising a nitrile rubber (a) having a bound unsaturated nitrile content of 43-60% by weight and a polymer Mooney viscosity (ML1+4, 100°) of 95-140 and a vinyl chloride resin (b).

Abstract: A vulcanizable rubber composition comprising (1) a hydrogenated product of an unsaturated nitrile-conjugated diene-unsaturated carboxylic acid ester copolymer, (2) an ultrafine magnesium silicate powder having an average particle diameter of not larger than 10 .mu.m and (3) a vulcanizer. This rubber composition gives a vulcanizate having good resistance to hydrofluorocarbon gas transmission and good cold resistance, and is useful for a hose for hydrofluorohydrocarbon gas.
