Abstract: A detection processing unit detects an obstacle in the traveling direction of a work vehicle. A bypass setting processing unit sets a bypass starting position which is a starting position of a bypass route (Rse) for the work vehicle to travel while bypassing the obstacle detected by the detection processing unit, and a bypass end position which is an end position of the bypass route. When the detection processing unit detects the obstacle, a travel processing unit causes the work vehicle to travel on the bypass route.

Abstract: A fruit vegetable harvesting device includes an operating tool (e.g., a cutting mechanism that operates a fruit vegetable (e.g., cuts a stalk), a fruit vegetable holding mechanism that sucks and holds the fruit vegetable, and an advance and retreat mechanism that advances and retreats the cutting mechanism to and from the fruit vegetable held by the fruit vegetable holding mechanism. The advance and retreat mechanism includes an extendable arm unit having a tip end to which the cutting mechanism is attached, and the cutting mechanism is held to be rotatable about a second rotation shaft with respect to the arm unit.

Abstract: A suction pad configured to suck and hold a fruit includes a pad main body made from an elastically deformable member and having a held base end portion; a hollow formed inside the pad main body so as to extend from a base end side to a tip end side; and a hole configured to communicate with the hollow and being open to a tip end portion of the pad main body, and an opening diameter of the suction hole is smaller than an inner diameter of the hollow.

Abstract: A sealing device includes a plurality of non-contact seals provided along a sealed shaft; a contact seal provided on at least one of two sides of the plurality of non-contact seals; an injection part that supplies purge gas into a first space of spaces arranged in an axial direction of the sealed shaft, the spaces being between the plurality of non-contact seals and the contact seal; and a collector that collects the purge gas from a second space of the spaces between the plurality of non-contact seals and the contact seal, the second space being positioned to be next to the first space in the axial direction.

Abstract: A connector adapted to be detachably connected to a flat electric cable having terminal members including contact portions and legs connected to the contact portions which are bent in such a manner that the end portions of the legs are staggered alternately in a zigzag manner forming two lines of legs. The end portions of the legs extend either in the axial or the direction perpendicular to the axial direction of the connector. The legs may be made of equal length before bending and or bent preferably such that the ends of all of the legs flow substantially in the same plane.
