Abstract: The present disclosure provides a slat unit for a livestock barn that significantly reduces efforts in a laying operation and that is hygienic and highly durable. A slat unit 10 for a livestock barn made of stainless steel that is a preferable floor material at an excretion area in a livestock barn includes at least a plurality of elongated slat panels 12, one or more horizontal members 14 that connect the plurality of slat panels 12 arranged side by side in a crosswise direction and in parallel in a longitudinal direction of each slat panel 12. Both longitudinal sides of each of the slat panels 12 are mountain-folded to form side wall portions 16. An angle between a planar portion 15 of each of the slat panels 12 and the respective side wall portions 16 is smaller than 90°.

Abstract: A fuel control apparatus of an engine comprises fuel control means for controlling fuel supply means so that an amount of fuel supplied to the engine corresponds to an intake pressure on the basis of a signal outputted from intake pressure detecting means for detecting the intake pressure of an intake passageway, intake resistance changing means for changing a resistance of the intake air flowing through the intake passageway correspondingly to the operating condition of the engine, and correction means for correcting a supply amount of the fuel to be controlled by the fuel control means when the resistance of the intake air flowing through the intake passageway is changed by the intake resistance changing means.
