    摘要: In a process for preparing a one-package RTV organopolysiloxane composition comprising (A) an organopolysiloxane containing at least two Si—OH groups or hydrolyzable groups, (B) an organosilane having at least two hydrolyzable groups or a partial hydrolyzate thereof, and (C) an inorganic filler, components (A) and (B) are premixed in a substantially anhydrous state, and component (C) is then added to the premix. Despite the absence of sag-control agents, the composition in the uncured state has a sufficient viscosity for sag-control, ease of extrusion, and improved slump properties.

    摘要: A work vehicle is provided with an engine, a traveling device driven by driving force from the engine to cause the work vehicle to travel, a first hydraulic pump driven by the driving force from the engine to discharge hydraulic oil, and a cooling device having a cooling fan driven by the hydraulic oil supplied by the first hydraulic pump to cool the engine, and a control unit. The control unit performs a normal cooling control in which an upper limit fan speed is determined based on an engine speed, and a cooling suppression control in which the upper limit fan speed determined based on the engine speed is suppressed to be less than the upper limit fan speed during the normal cooling control when a predetermined operation required to increase the engine speed is performed.
