Title: Diversity receiver and its method
Inventor: SHIBATA KOJI
IPC: H04N5/44
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide the diversity receiver and its method where a correct antenna is selected quickly and accurately in the case a TV tuner is detuned so as to eliminate detuning. SOLUTION: When no vertical synchronizing signal has been detected, that is, no vertical synchronizing signal is detected from an output signal of a level processing, a control section changes setting (change of an antenna that is normally connected) of an antenna that is set to be an antenna connected at all times into a next antenna to the former antenna in a predetermined order (steps U1, U2). Then after waiting for lapse of a time equivalent to, e.g. 3V (3-field) period (step U3), the processing returns to the step U1 and a vertical synchronizing signal is detected. In the case that a deteriorated reception electric field strength continues, no vertical synchronizing signal is detected and the processing in the steps U1, U2, U3 continues successively.

Abstract: PURPOSE: To improve the AC motor driver by an inverter operated in a pulse width modulating mode. CONSTITUTION: A multiphase DC/AC power converting bridge 16 is supplied with a DC power from a DC power source 10. The power converting bridge 16 operates an AC generator, in which the DC is converted into an AC power by a semiconductor device. A motor adjuster 26 receives signals concerning the revolution ω of a motor, the magnetic flux ϕ of the motor, etc., and outputs signals to a current switching block 40. The current switching block sends the output signals, together with another current signal by a current sensor 48, etc., to a gate signal 56, so as to control the power converting bridge. Moreover, a torque command 32 is sent to the current switching block 40 through a function block 60. Hereby, the control is performed by raising the modulation frequency when the torque is small, and lowering the modulation frequency, when the torque is large.  Hereby, the driver can be operated efficiently.
