摘要： In forming helical splines with stoppers on a rotary shaft, its large-diameter portion is held between a pair of rolling tools, each of which comprises: a helical teeth forming die having inclined teeth; an aligning teeth die having aligning teeth which are aligned with every other inclined tooth when combined with the helical teeth forming die; and a finishing teeth die having finishing teeth which are equal in pitch to the aligning teeth. Under this condition, the shaft is rolled under pressure by moving the rolling tools, to form helical grooves, and communication grooves communicated with every other helical grooves on the large-diameter portion, leaving stoppers between the communication grooves. Hence, the helical splines are formed by one rolling operation, with burrs formed between the spline grooves and the communication grooves being automatically removed.

摘要： A fuel injector system permits easier control for turning ON/OFF a spill control solenoid valve of a high pressure supply pump. The cam has a greater number of rising slopes for pressurizing the fuel by the plunger than the number of the fuel injection for each rotation of the engine. An electronic control unit controls the closing timing of the spill solenoid valve so that the period of synchronous delivery which is synchronized with the fuel injection is longer than the period of asynchronous delivery which is not synchronized with the fuel injection. Further, the unit adjusts the closing timing of the spill solenoid valve according to engine load.

摘要： A starter device having a reduced output shaft diameter is provided. A stopper mechanism for impeding the outward movement of the pinion (12) along the output shaft (3a) is implemented by forming the helical splines (31) on the output shaft (3a) as being alternately open (31a, 31b) and closed (32a) helical splines. The thrust washer (21), for bearing the outward axial force of the output shaft (3a), is disposed in the front bracket (5) of the starter in front of the front bearing (16) and opposed to the front end (3d) of the output shaft (3a). Both the stopper mechanism and thrust washer configuration according to the invention allow for a reduced diameter of the output shaft (3a). The reduced diameter of the output shaft, in turn, affords the option of making the pinion (12) smaller in diameter.

摘要： A direct-current motor is provided with a field pole including a main magnetic pole having an axial length of Lm and an auxiliary magnetic pole; and an armature core which is rotatably supported opposite to the inner peripheral side of the main magnetic pole and rotated by the excitation force of the field pole and has an axial length of Lc. The direct-current motor which satisfies the relation of Lm>Lc is such that the corner portions of the main magnetic pole are formed so that the relation between the axial length Ln of the straight section of the main magnetic pole and Lc satisfies 1.15 Lc>Ln.gtoreq.Lc. Therefore, a direct-current motor can be made more lightweight without changing its output characteristics by cutting down the corner portions of the main magnetic pole.
