  • Patent number: 9066469
    Abstract: A riding lawn mower includes: a delivery passage for delivering cut grass from a housing to a receptacle; and a shutter mechanism provided on a lower portion of the delivery passage for switching the mower between a bagging mode in which cut grass is delivered from the housing to the receptacle and a mulching mode in which cut grass is discharged downward of the housing. The shutter mechanism includes a horizontal pivot shaft disposed on the lower portion of the delivery passage, and a shutter plate pivotable about the pivot shaft between a fully closed position where the shutter plate closes the delivery passage to place the mower in the mulching mode and a fully opened position where the shutter plate is laid down toward a discharge side of the delivery passage to place the mower in the bagging mode.

  • Patent number: 7845442
    Abstract: A handle structure of a walk-behind working machine includes: a handle having left and right raised portions extending upward from a handle frame and a cross portion interconnecting the left and right raised portions; and a main clutch lever shiftable from a clutch-OFF position to a clutch-ON position by being pivoted into pressed abutment against the cross portion. The main clutch lever is constructed in such a manner that, when the main clutch lever is in abutment against the cross portion, a space for allowing a human operator to grip the left and right raised portions is secured between the left and right raised portions and the main clutch lever.

  • Patent number: 7760963
    Abstract: A method employing a statistic means to test whether or not luminance signals around a point of interest are distributed according to the same probability distribution with respect to luminance signals of respective pixels constituting the image; determining a range where the same probability distribution can be regarded as being satisfied, estimating the true luminance value of the point of interest by using the luminance data of the range. Especially when the image signals are faint to such an extent that the intensity of the luminance signal is based on the Poisson distribution, it is effective to perform a smoothing processing for each of the probability distributions of the signals and the noises by a test of a uniformity of the Poisson distribution, enabling a clear and denoised image to be obtained.
