  • Patent number: 9309827
    Abstract: A fuel injection control device includes a throttle opening read timing setter that sets the timing at which a throttle opening is read. The setter is triggered to detect the throttle opening used for calculation of a basic injection amount by the start of calculation timing of the basic injection amount (FICAL) if the FICAL is at the position corresponding to a toothless part of a crank pulsar rotor. The setter detects the throttle opening based on crank pulse interrupt according to a crank pulse if the FICAL is at a position other than the position corresponding to the toothless part.

  • Publication number: 20140318250
    Abstract: In a butt-welded joint structure in which the entire peripheral edge or both end sides of the abutting surface are welded, first and second cutouts for determining insufficient penetration and determining excessive penetration are formed. After butt welding, ultrasound is beamed onto each of the first and second cutouts of the joint structure and the reflected wave is measured. The acceptability of the weld penetration depth is thus determined on the basis of both of the reflected waves. This determination is performed on the entire peripheral edge portion or both end side portions of the butted face between the welded materials, and the acceptability of the weld penetration depth of the corresponding portions is inspected.
