Abstract: A front cowl covers a front portion of a vehicle provided with a headlight. The front cowl including: an intake port that takes in traveling wind from a front side of the vehicle; and a wind guide passage that allows the traveling wind to flow from the intake port toward a rear side of the vehicle. A bottom surface of the wind guide passage is inclined to be higher from the intake port toward the rear side of the vehicle, and the traveling wind is guided outward in a vehicle width direction from the intake port toward the rear side of the vehicle.

Abstract: A cowling structure for a straddle-type vehicle. The cowling structure includes a front cowling covering a vehicle front portion from a front side, and a pair of side cowlings covering the vehicle front portion from lateral sides. The pair of side cowlings each includes an outer cowling forming an outer surface of the side cowling, and an inner cowling forming an inner surface of the side cowling. The outer cowling at least includes a first outer cowling facing a first region of the inner cowling, a second outer cowling facing a second region of the inner cowling, and a third outer cowling covering, from an outer side in a vehicle width direction, a joint between the first outer cowling and the second outer cowling.

Abstract: A cowling structure includes a front cowling covering a vehicle front portion from a front side, and a pair of side cowlings covering the vehicle front portion from lateral sides. The front cowling is fixed to the pair of side cowlings, and is supported by a vehicle body frame via a cowling brace.

Abstract: A delay diagnosis method is proposed that can avoid design steps from being retraced or repeated uselessly due to defective delay when we design a semiconductor integrated circuit including a plurality of blocks. This delay diagnosis method has the steps of inputting logic information and floor plan information, finding the number of start points connected to the end point of a path from the logic information, computing the logic stage number of the path from the number of start points, finding block-to-block distances from the floor plan information, computing intra-block delays from the logic stage number and gate unit-value delays, computing inter-block delays from the block-to-block distances and routing unit-value delays, and diagnosing if the delay of the path after logic synthesis can be converged within a target path delay from the relation among the computed intra-block delays and inter-block delays and the target path delay.

Abstract: Each flip-flop-to-flip-flop path delay and a target machine cycle obtained in the stages of physical design and packaging design are used as input, and with respect to a path in which the path delay is not less than the target machine cycle, a closed loop including the path is extracted, and the timing of a clock signal of each flip-flop is adjusted so as to permit data transmission along the closed loop in a required cycle-number. At this time, a path along which data transmission is impossible in the target machine cycle or a closed loop including the path is listed in order to be modified. As methods of supplying a clock signal to each flip-flop, a plurality of methods different in the adjustable range of clock timing are combined and used.
