Abstract: Provided is a work-machine erroneous forward/backward travelling operation notifying device capable of improving safety by notifying, when a travel direction inputted to an operation input unit does not conform to the condition of a transmission clutch, an operator of the non-conformance. Whether the conditions of clutches 121 to 124 conform to a travel direction inputted to a selection lever 141 is determined on the basis of a pressure Pf sensed by a first pressure sensor 133a or a pressure Pr sensed by a second pressure sensor 134a and the travelling direction inputted to the selection lever 141. When it is determined that the conditions of the clutches 121 to 124 do not conform to the travel direction inputted to the selection lever 141, a vehicle 10 is notified that an erroneous operation will occur.

Abstract: A component fastening structure has a first component and a second component connected by a bolt and a nut. The first component includes a through hole through which a bolt is inserted, a seating face on which the bolt head is mounted near an upper end opening of the through hole, two rotation preventing wall portions which are formed near the seating face at both sides of the head to position the head between them, and lifting suppressing portions which are formed at positions apart above the seating face on the individual rotation preventing wall portions and protruded toward the head side. The interval between the two rotation preventing wall portions is smaller than the distance between the tip ends of two arm parts formed on the bolt head, and the seating face sides of the lifting suppressing portions are opposed to the upper surfaces of the arm parts.

Abstract: A layered three-dimensional radiation position detector includes two-dimensional scintillator arrays that are pixelated by optically discontinuous surfaces and stacked on a light receiving surface of a light receiving element, responses of scintillator elements detecting radiations being made identifiable on the light receiving surface to obtain a three-dimensional radiation detection position. A scintillator array lying on a radiation incident surface side has a pixel pitch smaller than that of a scintillator array lying on a light receiving element side so that the scintillator array on the radiation incident surface side has increased resolution. A layered three-dimensional radiation position detector achieving both low cost and high resolution can thus be provided.
