An air conditioning system is arranged to use a power line for communication. The air conditioning system includes one or more indoor units, one or more outdoor units, and a system controller for controlling the indoor units or outdoor units and executes communications between the indoor units and the outdoor units as overlapping a signal on the power line for supplying electric power. The outdoor units are connected with the system controller through a leased communication line. The indoor unit provides a power line communication device being connected with the power line. The outdoor unit provides a leased communication device being connected with the leased communication line. A bridge is also provided for connecting the leased communication line and the power line. The control information is exchanged mutually between the indoor units, the outdoor units and the system controller through the power line.

A demodulator device of the present invention receives a propagation signal including a plurality of channel signals multiplexed with each other, that is modulated by using an orthogonal code sequence, through different propagation paths. The demodulator device includes propagation path estimators for performing operations including propagation path estimation and demodulates the received propagation signal by subjecting outputs of the propagation path estimators to multi-path combination. More specifically, for information obtained by correlators corresponding to operations, the demodulator device performs the multi-path combination by combining results of multiplications of the outputs of the propagation path estimators for correlation values and then separate the plurality of channels.

In an electromagnetic induction heating apparatus, a cooking vessel made of a nonmagnetic metal, which has conventionally been incapable of magnetic inducting heating, is provided adjacent a heating coil which applies an alternating field with a high-frequency of at least 50 kHz. An inverter circuit for supplying the heating coil with a high-frequency current operates in response to an output signal from a detector which automatically detects the magnetic characteristics of the metallic material of the cooking vessel. As the high-frequency magnetic field is applied, a skin effect is produced within the metallic material of the vessel, so that the impedance for the magnetic field of the vessel is substantially fixed without regard to the wall thickness of the vessel.

摘要:
An improved anti-skid system for a vehicle which effectively utilizes an approximated slip ratio between vehicle or body velocity and wheel velocity to generate a brake release signal for a brake release valve but without actually utilizing a vehicle or body velocity detector. Storage apparatus is used to store a reference signal representing vehicle velocity but actually corresponding to a present or just past maximum value of wheel velocity. Control apparatus is then utilized for removing energy from the storage apparatus at a controlled predetermined rate chosen to approximate the expected vehicle deceleration (but without using an actual vehicle or body deceleration detector) such that the reference signal (capacitor voltage) will continue to accurately represent approximate vehicle velocities even during periods of deceleration. Various exemplary embodiments are described for the control apparatus which may be used to hold the discharge rate constant, to change it from a first low rate to a second high rate during brake release (for compensating inherent time lags in the vehicle brake system) and/or to continuously change the rate in an inverse dependency upon wheel deceleration to even more closely approximate actual vehicle deceleration under variable road conditions. Other features of the improved system may be used to result in rapid oscillatory brake releases as a transition both before and after a more prolonged brake release period to provide for smoother operation of the anti-skid system. Spurious influences of any A.C. ripple components on the detected wheel velocity signal may also be substantially eliminated by using some of the features of this system.
