Title: Flyback transformer
Inventor: IMAMURA NOBUAKI
IPC: H01F38/42
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a flyback transformer by setting the turn ratio of secondary winding to primary winding at a specified value or above. SOLUTION: In the flyback transformer 1, turn ratio of secondary winding 7 to primary winding 2 is set at 80 or above and the peak current flowing through the primary winding decreases as the turn ratio of secondary winding to primary winding increases. Consequently, temperature rise of the core is decreased as the turn ratio is increased. Since the number of turns is increased as the turn ratio is increased excessively and the winding width or the number of layers is increased to cause increase in the overall size of the flyback transformer 1, the turn ratio is preferably set up to about 120. When the turn ratio is 80 or above, temperature rise of the core can be suppressed sufficiently even if the core diameter is decreased and a flyback transformer 1 having small overall size can be obtained.

Title: Solenoid drive circuit
Inventor: SHIMAMURA MASAHIKO
IPC: H03K17/06
Filed: 1988-10-21
Abstract: PURPOSE:To facilitate a high speed control in a duty control by a method wherein the gate and source of a driving stage FET are connected to each other through a different FET and a predetermined electric source is connected to the gate of the different FET and, on the other hand, a constant voltage diode is inserted between the drain and source of the driving stage FET. CONSTITUTION:A driving stage FET 2 is inserted between an electric source VB and a solenoid 1 by connecting its drain D to the electric source side and its source S to the solenoid side. An input voltage VIN which is applied to the gate G of the FET 2 through a charge pump circuit 3 is controlled for the ON-OFF control of the solenoid 1. If the input voltage VIN declines and the gate G voltage of the FET 2 takes an L level, the FET 2 is turned OFF. However, as the solenoid 1 is in an energy discharge state, it tends to keep a current flowing. As a minute current is applied to the source S side of the FET 2 through an FET 4 at that time to keep the potentials of the gate G and source S of the FET 2 equal to each other, the FET 2 is not turned ON. Moreover, by the operation of a constant voltage diode 6, the solenoid 1 can be cut off more quickly by an inductance discharge.
