Abstract: PURPOSE:To reduce the generation of noise by employing a planetary roller type traction drive for a speed increaser and mounting a resilient damping material on the outer periphery of a ring roller, in a wind mill wherein a wing is coupled to a generator through the speed increaser. CONSTITUTION:When a wing 1 receives wind for rotation, the rotation is transmitted to a speed increaser 2 through a blade input shaft 4 and then transmitted to a generator 3 through an output shaft 5 to generate a power. In this case, a two-stage speed increase planetary roller type traction drive is used for the speed increaser 2. A star type planetary roller type traction drive is used for a speed increase first stage on the wind 1 side and a planetary type planetary roller type traction drive is used for a speed increase second stage on the generator 3 side. Composite type sheet plates 10 and 21 for damping formed such that a viscoelastic high molecular material is nipped between two steel sheets are attached to the outer peripheries of ring rollers 11 and 20 of each traction drive. This constitution reduces the size of the speed increaser and reduces the generation of noise.

Abstract: PURPOSE:To check a cycle variation as well as to secure stable driving, by detecting an actual lift period of a fuel injection valve and thereby compensating a drive pulse signal, in case of a device being supplied with fuel in quantity almost proportional to the lift period of the fuel injection valve. CONSTITUTION:During engine driving, each signal out of respective sensors 12 and 13 detecting a suction air quantity and an engine speed each is set down as a parameter, and furthermore a drive pulse signal of the pulse width based on the target life period tauo operated in adding some compensation by water temperature or the like is impressed on a fuel injection valve 11 of the corresponding cylinder. Next, the actual lift period taur produced by the impression of this drive pulse signal is compared with the target lift period upon being measured from a lift signal and a seating signal out of a lift sensor 15. And, when both these periods are incongruent with each other, pulse width tau of the drive pulse signal is compensated as tau+(tauo-taur), and the fuel injection valve 11 is driven by the drive pulse signal after compensation.
