摘要： A fuel injector includes a valve seat member formed with a valve seat and a valve element including an abutting portion to abut on an abutting portion of the valve seat. One of the abutting portions of the valve seat and the valve element includes a surface layer which is softened by heat treatment, and which is pressed by abutment between the valve seat and the valve element.

摘要： A driving apparatus electrically drives first and second components built in an industrial instrument. The first component drives a first element, and the second component drives a second element at a velocity higher than that of the first component. The driving apparatus includes a housing including a supply inlet and an exhaust outlet. A fan forms an air current so that air is taken into the housing through the supply inlet and is exhausted from inside the housing through the exhaust outlet. A driving circuit block is accommodated in the housing so as to be cooled by the air current, and includes a first driving circuit to electrically drive the first component, and a second driving circuit to electrically drive the second component. The second driving circuit is inserted upstream of the first driving circuit along the air current in the housing. A cooling unit regulates a temperature of the air exhausted from inside the housing through the exhaust outlet so as to decrease a temperature difference between the air taken into the housing through the supply inlet and the air exhausted from inside the housing through the exhaust outlet.
