Abstract: Provided is a work machine with a display device capable of reducing the usage of the capacity of a memory without increasing the cost while realizing display using image data in which the sharpness when being displayed is ensured. A hydraulic excavator 1 comprises: a monitor 4 for displaying a plurality of work mode screens 401 used during work and a plurality of service mode screens 402 used during maintenance; and a controller 6 for controlling display of the monitor 4, wherein the controller 6 stores first image data to be displayed on the plurality of work mode screens 401 and second image data to be displayed on the plurality of service mode screens 402, and the second image data includes specific image data X1 having a quality set to be different from a quality of the first image data.

Abstract: A saddle-riding type vehicle includes a seat, a fuel tank including a vent and disposed below the seat, a canister connected to the vent, and an overflow prevention valve provided in a fuel vapor passage connecting the vent and the canister. The overflow prevention valve is positioned higher than the vent.

Abstract: A vehicle includes a storage case. The storage case includes an opening. The storage case is disposed above a cylinder portion, and the opening is disposed farther forward than the front end of the upper surface of the seat. An air cleaner and a fuel tank are disposed below the seat. According to such a vehicle, it is possible to ensure a space for the storage case anterior to the seat. As a result, it is possible to readily increase the capacity of the storage case. In addition, a rider is able to access the opening while sitting on the seat.

Abstract: Disclosed are alloying elements and microstructures suited for realizing a marked increase in strength of low-carbon or ultra-low-carbon steel plate using a high-density energy source such as a laser. Steel blanks satisfying both high formability and high strength requirements are provided which show sufficient press formability and yet can be markedly increased in strength by laser treatment or which have been markedly increased in strength by laser treatment in areas not to be subjected to severe forming.
