Inventor: MITA KAZUTOSHI
IPC: H02M7/48
Filed: 2002-05-31
Abstract: <P>PROBLEM TO BE SOLVED: To surely and stably reduce an output with a simple constitution.  <P>SOLUTION: When excessively deeply dimmed, a voltage of an electrolytic capacitor C9 of a partial smoothing circuit 36 is lowered. Since a field effect transistor Q6 is turned on, an auxiliary resonance is 24V. If a voltage of a capacitor C16 becomes lower than 15V, a Zener diode ZD3 is turned off, a parallel capacitor C12 is connected to a capacitor C11 in parallel, an amplitude is made smaller while making the auxiliary resonance frequency of field effect transistors Q4, Q5 higher, an output of a main circuit for an inverter 37 is made smaller, and an arc tube 18 is turned off. Unless a voltage of the capacitor C16 of the partial smoothing circuit 36 becomes higher than 19V by enlarging again a dimming degree, since the Zener diode ZD3 is turned on and the field effect transistor Q6 is not turned on, the parallel capacitor C12 is not connected to the capacitor C11 in parallel. A hysteresis is given to the voltage when the arc tube 18 lights off and relights.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-06-05
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a switching device capable of improving operability of a remote switch.  <P>SOLUTION: For the switching device 10, an adjusting value is changed according to the change of the attitude of a regular switch 12 or the remote switch 30 depending on a rotational operation. When one switch out of the regular switch 12 and the remote switch 30 is rotated to change the adjusting value, The other switch is rotated and the attitude is made to correspond to the adjusting value after the change.
