IPC: H01F27/32
Filed: 1981-10-30
Abstract: PURPOSE:To improve the cooling efficiency through the reduction of the contact heat resisance between a leaf conductor and an insulating sheet by forming a soft layer therebetween. CONSTITUTION:An aluminum leaf conductor 12 and an insulating polyester sheet 3, together with an extremely thin polyethylene sheet 15 interposed therebetween, are wound on the outside of an iron core 1 to form a low-voltage winding 4 and a high-voltage winding 5.

Title: Fluorescent lamp control device
Inventor: MATSUZAWA SHIGEO
IPC: H05B41/24
Filed: 1992-06-30
Abstract: PURPOSE:To eliminate risk of damage of any circuit component due to failed current in the final lifetime period of the tube of fluorescent lamp and prevent drop of the illumination effect resulting from blinking of the lamp by sensing the final period of the tube, and prohibiting the operations of a modulator circuit and dimming circuit. CONSTITUTION:When a fluorescent lamp 9 launches into its final lifetime period of tube and a large tube current I flows in a load circuit 7, it is sensed by a sensor coil 17, and the voltage V1 of a capacitor 24 rises. Because the capacitance of another capacitor 31 is large, the rise of its voltage V2 remains less, and H-pulses are fed to an output generator circuit 36 from an OP amplifier 28. The circuit 36 counts H-pulses a specified runs and stops the modulating operation of a modulator circuit 10. Also a dimming circuit 15 stops its dimming operation, and the output frequency of an oscillator circuit 2 is returned to the fundamental frequency. Accordingly a voltage with fundamental frequency out of modulation is impressed on the load circuit 7, and the fluorescent lamp 9 can not be re-lighted but extinguishes. Thus large current of the load circuit is suppressed, damage of circuit components is precluded, and drop of the illumination effect resulting from blinking of the lamp is prevented.
