摘要： The inclination of a reflecting surface of a mirror is adjusted such that light outputted from an input optical fiber is reflected by the mirror so as to be fed into an output optical fiber. The normal direction of the reflecting surface of the mirror vibrates about a predetermined direction at a predetermined frequency. A part of the light propagating through the output optical fiber is taken out by a light-branching part, so as to be received by a photodiode, whereby an electric signal having a value corresponding to thus received quantity of light is outputted from a detection circuit. Whether or not the electric signal includes a component of the predetermined frequency or whether the component is strong or weak is detected, whereby whether or not there is optical coupling from the input optical fiber to the output optical fiber or the extent thereof is determined.

摘要： A fluorescent lamp operating apparatus comprises a power switching element electrically connected to a fluorescent lamp having a pair of electrodes, and means for limiting the current flowing through the power switching element by controlling its conductance so as to prevent the power switching element from being broken by a large current flowing from the power line through the fluorescent lamp when the impedance between the pair electrodes decreases from infinity at the start-up of the fluorescent lamp.

摘要： A protection circuit has a series combination of a p-channel enhancement type field effect transistor, a first node and a first resistor connected between a high voltage line and a low voltage line and a series combination of a second resistor, a second node and an n-channel enhancement type field effect transistor also connected between the high voltage line and the low voltage line, and the first node and the second node are respectively connected to the gate electrode of the n-channel enhancement type field effect transistor and the gate electrode of the p-channel enhancement type field effect transistor; when one of the field effect transistors is broken down between the source node and the drain node due to abnormal voltage applied between the high voltage line and the low voltage line, the associated resistor varies the potential level at the gate electrode of the other of the field effect transistors due to the break-down current passing therethrough, and causes the other of the field effect transistors to turn on so as to increase the current discharging capability of the protection circuit.
