Title: Generator
Inventor: BABA ISAO
IPC: H02K19/34
Filed: 1983-06-27
Abstract: PURPOSE:To enable to simultaneously generate two types of voltages having high and low frequencies by one generator by winding a low and high frequency armature windings on a stator core. CONSTITUTION:Exciting windings 5a, 5b are radially wound on a rotor core 6 so that salient poles become the same number of two groups 6Aa, 6Ba. The salient poles 6Aa of the portion A of the core 6 are all excited to N-poles by the windings 5a, 5b, and the salient poles 6Ba of the portion B are all excited to S-poles. A single phase AC output can be obtained from the armature winding 12 wound in the slot 2. When the poles 6Aa of the portion A are all excited to N-poles and the poles 6Ba of the portion B are all excited to S-poles, the bottom of the recess 6Ab between the poles 6Aa is slightly excited to the N-pole, and the bottom of the recess 6Bb between the poles 6Ba is slightly excited to the S-poles. High frequency 3-phase outputs are obtained from 3-phase armature windings 4 wound in the slots 2.

Title: Output gate circuit
Inventor: ITOU HIROYUKI
IPC: H03K19/086
Filed: 1983-06-24
Abstract: PURPOSE:To make the circuit suitable for a highly integrated circuit LSI with reduced circuit area without deteriorating the performance such as circuit speed and logical capability or the like by using an output emitter follower transistor (TR) to a base of which an output of a TR is applied and from the emitter of which an output is extracted. CONSTITUTION:An OR or an NOR output is obtained to the emitter of the emitter follower TR47 as same as an internal gate circuit and its output is inputted to a base of a TR59. A linear inverter circuit comprising the TR59 and resistors 56, 57 outputs a high level as a VOUT, because the TR59 is nonconductive and a high level signal is applied to a base of the output emitter follower TR9 when an emitter (NOR output) of the TR47 is logical low level. Conversely, when the emitter of the TR47 is logical high level, the TR59 is conductive and a voltage drop is produced across the resistor 56, then a low level signal is applied to the base of the TR9 and a low level is outputted as the VOUT.
