Abstract: Provided is a high-quality fuel delivery pipe that is formed by stacking, braze-joining and integrating upper and lower cases, and is provided with excellent pressure resistance by reinforcing a portion having a low braze joint strength. This fuel delivery pipe formed by stacking, braze-joining and integrating the upper and lower cases is characterized in that a reinforcement member is provided on a side wall portion of the lower case that overlaps a side wall of the upper case separately from or integrally with the lower case, both the reinforcement member and the lower case are fitted into the upper case so that the reinforcement member and the lower case overlap the upper case, and the overlapping portions are joined and integrated together by copper brazing.

Abstract: A robot arm apparatus includes a base structure, a first arm, a first actuator, and an assisting device. The first arm is pivotable relative to the base structure about a first pivot axis. The first actuator is configured to pivotally actuate the first arm relative to the base structure. The assisting device is configured to apply an assist rotational force to the first arm to assist the first actuator.

Abstract: A robot system includes a robot arm including arms and joint parts such that each of the joint parts is connecting two arms, and an auxiliary arm including links, joints and sensors such that each of the joints is connecting two links and that the sensors detect rotation angles of the joints. The auxiliary arm has an end attached to the robot arm at a position which includes multiple joint parts of the joint parts from a base end side to a front end side of the robot arm such that the auxiliary arm follows movement of the robot arm.

Abstract: A robot includes: a base portion to be installed on an installation surface; an arm portion having a base end coupled to the base portion, the base end being rotatable around a rotation shaft disposed approximately parallel to the installation surface; and a balancer having one side rotatably coupled to the base portion and another side rotatably coupled to the arm portion. The arm portion includes a pair of arm constituting plates each coupled to the rotation shaft and facing each other, and at least a part of the balancer is arranged between the pair of arm constituting plates.

Abstract: A joint mechanism includes a motor including a motor shaft and a hypoid pinion provided at a tip end of the motor shaft and a speed reducer configured to reduce a rotation speed of the motor at a speed reduction ratio. The speed reducer includes a screw-shaped input shaft and a ring-shaped gear meshing with the screw-shaped input shaft and three-dimensionally intersecting the screw-shaped input shaft at a right angle. Further, the screw-shaped input shaft includes a shaft body provided with a screw portion and a hypoid gear arranged at one end of the screw-shaped input shaft and configured to mesh with the hypoid pinion. Furthermore, the screw-shaped input shaft has an axis three-dimensionally intersecting the motor shaft at a right angle.

Abstract: A backlight unit has an external electrode fluorescent lamp in an housing. The external electrode fluorescent lamp includes a glass bulb having a discharge space inside, and electrodes around both ends of the glass bulb. A protective layer and a phosphor layer are formed on an internal surface of the glass bulb in this order. The glass bulb is made of soda glass, and sodium oxide precipitated from this soda glass appears on part of the internal surface of the glass bulb where the protective layer is not formed, so as to be exposed to the discharge space.
