摘要:
A battery monitoring system, comprises a battery state detection circuit that detects battery states of a plurality of battery cells that are connected in series, based on respective cell voltages of the plurality of battery cells, and a control circuit that monitors state of a battery cell, based on each cell voltage of the plurality of battery cells. The control circuit inputs pseudo voltage information to the battery state detection circuit, and thereby diagnoses whether or not the battery state detection circuit is operating normally.

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.

摘要:
Two-wire television interphone system is arranged to discriminate by a line voltage discriminator incorporated in a master device a line voltage variation due to a calling operation on the side of a branch device, to actuate a voltage controller in the branch device to shift the system from standby state to operation state, and to drive a call signal generator in the branch device for actuation of a call signal receiver in the master device. The system is thus made to have a power supply circuit energized for a power supply to the system only when required for effecting the calling operation, talking between the both devices, and so on.
摘要:
This invention relates to an apparatus for thermal diffusion by means of high frequency induction heating suitable for mass production of semiconductor substrates of uniform quality; wherein a plurality of heating bases, each made of a material having good electric conductivity, and carrying semiconductor substrates, are continuously fed through a furnace tube where the bases are heated by means of high frequency wave excitation in order that each semiconductor substrate receives substantially the same thermal treatment.
