A feeding device for independently feeding, by a preparatory device, a binder strip and flap strips to a garment held by a base presses. There are eight types of combination in feeding fashions, whether or not the binder strip is to be fed, whether or not one flap strip is to be fed, and whether or not another flap strip is to be fed (2.sup.3 =8). Various feeding fashions are provisionally set in order prior to actual sewing, and control means controls actual operations of the preparatory device in accordance with the feeding fashions and every feeding fashions.

A contactless power transfer core used for a power transmission coil or a power reception coil of a contactless power transfer apparatus includes: a winding core part wound by an electric wire; and a magnetic pole core part constituting a magnetic pole portion provided at both sides of the winding core part. A height of the uppermost part of a ferrite plate arranged on a face of the magnetic pole core part at a side opposing a counterpart coil is equal to or greater than a height of an outer circumference of the electric wire wound around the winding core part, and a height of the ferrite plate of a face at a side not opposing the counterpart coil is lower than the height of the outer circumference of the electric wire wound around the winding core.

Provided is a contactless power transfer device for a moving object. Each of a power transmission coil and a power receiving coil comprises an H-shaped core, and first, second and third search coils are installed on a magnetic pole object of the H-shaped core of the power transmission coil. A y-direction positional deviation between the power transmission coil and the power receiving coil is detected using voltages measured at the first and second search coils, and an x-direction positional deviation is detected using voltages measured at the third search coils.

[Problems]To provide a non-contact power feeder that is high efficient and high power factor and has no load dependence.[Means for Solving Problems]A series capacitor Cs1 is connected to a primary winding 1 driven by an AC power supply 3 and a parallel capacitor Cp2 is connected to a secondary winding 2. The capacitance Cp is set to Cp≈1/{2πf0×(x0+x2)} and the capacitance Cs converted to the primary side is set to Cs≈(x0+x2)/{2πf0×(x0×x1+x1×x2+x2×x0)}, where f0 is the frequency of the power supply, x1 is a primary leakage reactance of the primary winding 1, x2 is a secondary leakage reactance of the secondary winding 2 converted to the primary side and x0 is an excitation reactance converted to the primary side. By setting Cp and Cs to the above values, the transformer of the non-contact power feeder is substantially equivalent to an ideal transformer. If it is driven by a voltage type converter, the output voltage (=load voltage) becomes substantially constant voltage regardless of the load. In case of a resistive load (ZL=R), the power factor of the power supply output always remains 1 even if the load may vary.

[Problems] To provide a series electric double-layer capacitor device having a simple structure eliminating nonuniform voltages induced among electric double-layer capacitors (C1 to C6).[Means for Solving Problems] A series electric double-layer capacitor device comprises 2n capacitors (C1 to C6), 2n diodes (D1 to D6), a transformer (T1), and an inverter (31). Secondary wirings (N1 to N3) of the transformer supply the induced voltages to a capacitor module (30) composed of sets of two capacitors and two diodes. The capacitors are charged when the diodes included in the capacitor module are conductive. The series electric double-layer capacitor device further comprises voltage adjusting means (32) for changing the DC voltage level between terminals (1, 2), and the inverter converts the voltage-changed DC voltage into an AC voltage. A voltage for canceling the forward voltage drops of the diodes is added to the induced voltages of the secondary wirings by the operation of the voltage adjusting means. The influence of the diodes of when the capacitors are charged is eliminated, and the voltages among capacitors are made uniform.
