Title: Ringing choke converter
Inventor: KOBAYASHI YASUO
IPC: H02M3/338
Filed: 1992-07-02
Abstract: PURPOSE:To prevent a switching element from repeating ONs and OFFs due to a resonance generated when the switching element is in an off-state by connecting a parallelly-connected resistor and diode or inductor to a driving circuit in series. CONSTITUTION:A resistor 12 and a diode 13, which are connected in parallel, are connected to a driving circuit serially. A resonance voltage which is induced in an auxiliary winding A when a MOSFET1 is in an off-state is added to a gate of the MOSFET1 through a resistor 4B of the driving circuit 4 and the newly set-up resistor 12. Therefore, a charging current of a gate capacitance 11 of the MOSFET 1 due to the resonance voltage is limited by the resistor 12 and thereby a rise of a gate voltage is prevented, resulting in preventing the MOSFET1 from repeating ON and OFF. By this method, an accident that the MOSFET1, a switching element, overheats and is eventually destructed is avoided.

Title: Call-processing method for wll system, subscriber equipment and access controller
Inventor: NOBUYASU YASUSUKE
IPC: H04B7/24
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To reduce load for call processing by returning a dial tone from subscriber equipment itself to a user, then the user performs off-hook. SOLUTION: A dial tone(DT) reception guarantee means 20 is provided for letting a user terminal 11' receive a DT without fail, in spite of the line conditions on the side of a subscriber exchange 9 after the off-hook of the user terminal 11'. This DT reception guarantee means 20 has a DT-generating part 21 for generating the DT and sending it out to the user terminal 11', when the off-hook is detected. Then, when the user terminal 11' performs the off-hook, the DT is outputted from user equipment 11. When a first dial number is transmitted from the user terminal 11' after the output of DT, the output of DT is stopped. Therefore, since the generation of DT and the transmission/stop control of that DT become close terminal processing near the user terminal 11', control is simplified and the load of call processing is reduced.
