Kyoritsu followed that design with a backpack/blower/misting machine in 1955. in 1968, Kyoritsu applied for a patent on a backpack blower mister design, and in 1972 established themselves in the United States as Kioritz Corporation of America, and is said to have invented the first leaf blower in 1977. The company changed its name to Echo in 1978.

An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
