Abstract: An image processing device includes a processor, in which the processor is configured to acquire a flow velocity vector of a fluid in a structure, generate a flow velocity vector image obtained by visualizing a spatial distribution of the flow velocity vector, and perform display control for changing a display aspect according to a magnitude of fluctuation of the flow velocity vector, in the flow velocity vector image.

Abstract: A cooling structure of an on-vehicle projector, includes: a projector including: a light source; an image projection part configured to project an image based on the light emitted from the light source and an image signal; and first and second vent holes configured to ventilate the internal space, in which the light source is arranged, with the outside; and an air introduction part configured to introduce conditioned air, sent from an air conditioner mounted in a vehicle, to the internal space through the first vent hole.

Abstract: Provided is power work equipment using a fuel container and/or a lubricating oil container that is/are easily replaced for the power work equipment, and supply(ies) liquid fuel and/or lubricating oil optimized for driving. A chainsaw (1A) (power work equipment) includes a main body (10) having an internal combustion engine (50), and a fuel container (90A) and/or a lubricating oil container (100A) detachably attached to the main body (10). A connection part (92) of the fuel container (90A) is connected with the fuel suction unit (60) in a liquid-tight manner, and the bag (91) is configured to collapse as liquid fuel (F) in the bag (91) decreases. A connection part (102) of the lubricating oil container (100A) is connected with a lubricating-oil suction unit (70) in a liquid-tight manner, and a bag (101) is configured to collapse as lubricating oil (L) in the bag (101) decreases.

Abstract: A compartment temperature adjustment switch 12 is provided for successively switching a target temperature of a compartment air conditioner through pushing operation of a push button 12a. The switch 12 includes the push button 12a, a substrate 22 fixed to the push button 12a, and light emitting elements 23 mounted on the substrate 22. The segments are selectively illuminated when the light emitting elements 23 are turned on, and a target temperature is numerically displayed on the push button 12a by a combination of illuminated ones of the segments. An information display portion is integrally formed with the push button 12a.
