    摘要: A vehicular power generator control apparatus includes a switching transistor, a voltage control circuit, a high rotation speed detecting circuit, a leakage detecting circuit and a maximum conduction rate restricting circuit. The leakage detecting circuit detects leakage current flowing to a P-terminal. When the leakage current is detected, a maximum conduction rate set by the maximum conduction rate restricting circuit is changed from a small value at low rotation speeds to a large value. Thereby, field current flowing in a field coil is increased, a large voltage is generated at stator coils and current flows to a rectifying circuit to thereby reduce the leakage current which flows to the P-terminal.

    摘要: According to one aspect of the present invention, a resin ferrule, for use in an optical fiber connector, is provided including: a capillary 1 having an axial part 2; and a flange 13 protruding from the axial part 2; the ferrule having an optical fiber insertion hole 3 axially passing through the capillary 1. The capillary 1 and the flange 13 are integrated into a monolithic structure with thermoplastic resin. The capillary 1 has a planar-shaped front end surface 11, and a front end part 10 extending towards the front end surface 11, in a convergent fashion where the front end part 10 has the outer diameter of the radial cross-section thereof reduced along the axial direction thereof towards the front end surface 11 with the cross-section kept concentric. According to another aspect of the present invention, a die is provided for molding a resin ferrule, for use in an optical fiber connector, as defined above. The die has portions defining: a first cavity 21 for forming the capillary 1; a second cavity 22 for forming the flange 13; a core pin 25 for forming the optical fiber insertion hole 3; an internal hole pin 31 for forming the front end part 10 of the capillary 1; and a third cavity 23 for engaging with the internal hole pin 31. The internal hole pin 31 has a recess part 33 for forming the front end part 10 of the capillary 1, the recess part 33 being formed on an end surface of the internal hole pin 31 on the side facing the first cavity 21. The third cavity 23 has an internal circumferential surface 24, having a coating film 30, made of aluminum and titanium nitride, formed thereon. The internal hole pin 31 is engaged with the third cavity 23 by having the coating film 30 positioned therebetween. According to a further aspect of the present invention, the die has only a ring gate 40 as a gate, the ring gate 40 being disposed on an end surface 22a of the second cavity 22 on the side corresponding to the insertion opening 7 of the optical fiber insertion hole 3. With this arrangement, an excellent resin ferrule and a molding die therefor are obtained having advantages in that the ferrule is equipped with a highly increased precision, that the material and working costs of the ferrule are greatly reduced, that the ferrule has an outer diameter of high precision and is enabled to be mass produced stably, and that an optical fiber is kept free from any damage during its insertion into the ferrule.
