摘要:
A direct-current power source apparatus in which a lithium-ion capacitor unit is used as an electric storage system and which can fully utilize the lithium-ion capacitor unit and maintain the supply of electricity to a load is provided. An electric storage system includes a lithium-ion capacitor unit and a lead-acid battery connected in parallel with a load, and a voltage detecting section that detects the voltage of the lithium-ion capacitor unit. When the voltage detecting section detects that the voltage of the lithium-ion capacitor unit has reached a unit lower-limit voltage, a control circuit outputs a conduction signal for causing a switching circuit to get into a conductive state. When the switching circuit gets into a conductive state, the secondary battery supplies an electric power to a motor. At this time, the secondary battery charges the lithium-ion capacitor unit.

Power supply equipment for a motor vehicle, includes a motor generator, an inverter for driving the motor generator, a battery and a capacitor of an electrical double layer. The capacitor is directly connected to a DC side of the inverter and the battery is connected in parallel with the capacitor via a first switching unit. When an engine is started up, the power stored in the capacitor is used, and the switching units are turned off to separate the battery from the start-up of the engine.

A connector A includes a plurality of conductors. Each conductor consists of a contact 1, a terminal piece member 2, and a connecting conductor 3 connecting the contact 1 with the terminal piece member 2. The conductors are respectively held on a body 10 of the connector. The connecting conductors 3 are arranged in three layers in such a position relationship that can prevent them from short-circuiting each other and also can prevent a crosstalk from being produced between them. In this structure, the connecting conductors 3 are arranged in two or more levels, which makes it easier for the connector to be designed for prevention of the crosstalk when compared with a structure in which the connecting conductors 3 are arranged in one plane.

A modular jack telephone type connector has a housing which is associated with a carrier on which metal conductors are mounted on a top surface of the carrier, a wire positioning fixture which has wire openings for inserting electrical wires and a cavity for receiving terminals of the conductors and is supported in a hole on the top carrier surface allowing the fixture to move vertically in the hole with respect to the carrier, vertical fins which are mounted on the carrier mates vertical grooves which are provided on an opposite side of the wire openings of the fixture for additional secure positioning, a lever which is pivoted at the housing, rotating toward or away from the carrier, and coupled to the fixture via an interlock mechanism in order to transmit a rotational lever motion to the vertical fixture motion. As the lever rotates toward the carrier and pushes the fixture downward, wires inserted into the fixture meets precisely terminals through the cavity of the fixture for insulation displacement electrical contacts without using special termination tools.

In a driving system comprising an engine, a plurality of motor-generators and a plurality of coaxial differential mechanisms, rotating output axes of the plurality of motor-generators are disposed parallel to and opposite to a rotating output axis of the engine. The coaxial differential mechanisms are arranged between the engine and the motors. The coaxial differential mechanisms are disposed so that straight lines passing through rotating axes of at least two of the coaxial differential mechanisms are parallel to each other, and the output power of the engine is transmitted to the coaxial differential mechanisms through gears. It is possible to provide a small sized and high productive driving system.

An expert system in which a plurality of knowledge descriptive layers are provided in a frame system. Each descriptive layer is composed of several frames. The frames of the lower knowledge descriptive layer correspond to the elements of a knowledge processing object system. The content of frames of the upper knowledge descriptive layers is determined as an inference made with reference to the frames of the lower layer. This determination is initiated and executed when the content of slots of the frames is updated.
