Title: Negative charge type electrophotographic toner and its production
Inventor: HATASE YOSHITERU
IPC: G03G9/087
Filed: 1994-09-26
Abstract: PURPOSE: To obtain good electrification property of each toner particle, to maintain images with high image density and no fog and to obtain a toner which can endure for a long-term use by incorporating a charge controlling agent (CCA) for negative charges and a CCA for positive charges into a toner having small particle size (small size toner) and incorporating a CCA for negative charges to a toner having large particle size (large size toner). CONSTITUTION: The toner consists of a small size toner and a large size toner. The small size toner contains a CCA for negative charges and a CCA for positive charges, while the large size toner contains a CCA for negative charges. By preliminarily incorporating CCA for positive charges into the small size toner having bad dispersion of CCA for negative charges to increase charges, the increase of charges of the toner is suppressed for development. The production process of the toner consists of a process to classify a toner having 7-12μm center particle size into the small size toner having <5μm particle size and the large size toner larger than the small size toner, a process to subject the small size toner to surface treatment with CCA for positive charges, and mixing the small size toner after the surface treatment and the large size toner.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain target band blocking characteristics with simple circuit constitution for the band blocking filter of asymmetrical frequency characteristics by cascade connecting serial/parallel resonance circuits through a serial reactance element. SOLUTION: Among respective circuit elements, an ideal reactance or an ideal susceptance are replaced for an inductance or a capacitance provided with the same reactance or the same susceptance at a center frequency. Thus, the plural serial/parallel resonance circuits, composed of a parallel resonance part using a TEM transmission line and a reactance element serially connected to it, are converted to the actual circuit elements cascade connected by the reactance element. For an asymmetrical equivalent band-stop filter circuit, the parallel resonance part of the serial/parallel resonance circuits of a first stage and a third stage is approximated by the λ/4-type TEM transmission line of a short stab and the parallel resonance part of the serial/parallel resonance circuit of a second stage is approximated by the λ/2-type TEM transmission line of an open stab.

Abstract: PROBLEM TO BE SOLVED: To reduce a parasitic capacitance component between secondary winding terminals by making a winding method of a secondary winding part winding or bank winding, in an AC current transformer constituted of an iron core using magnetic material and the secondary winding. SOLUTION: In a secondarily converted simple equivalent circuit of an AC current transformer, a resonance circuit is constituted of the respective reactance components due to exciting inductance 6, secondary leakage inductance 8 and a paracitic capacitance 10 between secondary terminals, and the transmission characteristic becomes the resonance frequency fc[=1/2π√(LCp)], if the secondary leakage inductance value of the inductance 8 is L, and the secondary parasitic capacitance value between terminals of the paracitic capacitance 10 is Cp.
