Abstract
Abstract A semiconductor-type voltage regulator principally constituted by semiconductors such as transistors, diodes, and the like without having any electrical contact, which is adapted to enhance the effect of radiation and to be small in size and is incorporated with a generator without lead wires to thereby simplify the structure of a charging generator apparatus including said generator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
36 words
A voltage regulator as in claim 1 wherein said connecting terminals have a flat rectangular cross section and a hole for receiving a mounting bolt thereby facilitating a good thermal and electrical connection to said generator.
Claim 2
Dependent Claim
87 words
A semiconductor-type voltage regulator for use with a generator, said regulator comprising: an active element integrated circuit including at least one transistor for interrupting a field winding of said generator, and a Zener diode for detecting the voltage of said generator, a passive element integrated circuit including dividing resistors for establishing a voltage to be applied to said Zener diode, and wherein said passive element integrated circuit is in stacked relationship and electrically connected to said active element integrated circuit thereby minimizing the size of said regulator.
Claim 3
Dependent Claim
58 words
A voltage regulator as in claim 3 wherein: said active element integrated circuit includes a plurality of lead terminals extending at an angle with respect to the plane of said active circuit, and said passive element integrated circuit includes a plurality of connecting terminals for mating with said lead terminals when said stacked relationship exists between said circuits.
Claim 4
Dependent Claim
31 words
A voltage regulator as in claim 4 wherein said passive element integrated circuit includes an exposed resistor such that the exposed resistor may be externally adjusted to a set point value.
Claim 5
Dependent Claim
112 words
A charging generator apparatus equipped with a semiconductor-type voltage regulator comprising: a plurality of combined heat radiating and terminal means for serving as heat radiators as well as electrical connectors, each of said combined means attached to an active element integrated circuit or to a separate passive element integrated circuit which elements comprise said voltage regulator, a brush holder having fitting members adapted to mate with fitting terminals for said regulator, said combined means and said fitting members and said fitting terminals being used to integrally fit said voltage regulator and said brush holder with said generator, and said regulator being thermally and electrically connected between said brush holder and said generator.
