A headstock 10 having a chuck 12 and a tailstock 20 having a shaft 21 are mounted on a bed 1 and can move with respect to each other in the direction of the Z-axis, A carriage 50 is slidably mounted on the bad 1 and can move in the Z-axis direction with respect to the rotational axis of a spindle 11. A turning device (lathe tool) 30 is provided to perform a turning operation on a workpiece and a gear cutting device 40 is provided to perform a gear cutting on the workpiece. The turning device 30 and the gear cutting device are preferably slidably mounted on the carriage 50 in a side-by-side relationship. The turning device 30 and the gear cutting device 40 may have respective traverse slide bases 31 and 41. The traverse slide bases 31 and 41 are mounted on the carriage 50 and can move independently in the direction of the X-axis perpendicular to the axis of the spindle 11, i.e. in a traverse sliding direction.

A continuously operable fuel injection device comprises a sleeve having a substantially triangular measuring window communicating with the outlet port of a main body, the sleeve being inserted in the cavity of the main body, and a control spool having an annular groove communicating with the inlet port of the main body through an axially extending hole and axially slidably inserted in the sleeve, the substantially triangular measuring window cooperating with the annular groove of the control sleeve to form a variable orifice. By axially sliding the control spool, any desired flow rate can be obtained.

A method of manufacturing a bearing ring of a bearing. This method includes the steps of forming recesses in both ends of an outer peripheral surface of a material ring having fiber flows extending substantially parallel to the outer peripheral surface and cutting into two ring halves the material ring at its center with respect to the direction of width. The ring halves are then brought together with their ends having the recesses facing to each other to form a bearing ring.
