摘要： A power supply system for supplying a d.c. current from a center equipment to a terminal device through a two-wire line, is capable of properly supplying the current for communicating purposes irrespective of the connection condition of the two-wire line and accurately stopping the supply of current to the terminal device in the non-communicating condition.

摘要： A DC-DC converter in which a DC voltage is intermittently applied to a transformer through a switching circuit performing repeatedly turning on-off operations. An offset is imparted to the voltage waveform applied to the transformer for separating a transition timing of the voltage applied across the switch circuit from that of the current flowing through the switch circuit, to thereby reduce the power loss.

摘要： An electric fan apparatus including connectors that employ male terminals. Intermediate terminals are employed to connect the male terminals of the connectors. A fan motor is located behind a radiator to rotate a fan for producing air flow that cools the radiator. A controller controls the fan motor. A socket connector is provided on the fan motor or the controller. The socket connector has a sink for accommodating a male terminal. A plug connector is provided for engagement with the socket connector. The plug connector also has a sink for accommodating a male terminal. An intermediate terminal electrically connects the socket connector male terminal and the plug connector male terminal when the socket connector and the plug connector are engaged with each other. The intermediate terminal has back-to-back female ends that are fitted onto the male terminals to bridge the male terminals.
