摘要： A system for a direct digital down conversion of a 10.8 MHz intermediate frequency signal in the personal handy phone system. The present invention includes a system that enables a direct digital down conversion of a 10.8 MHz intermediate frequency signal into a digital baseband signal within cell stations and portable stations of the personal handy phone system. To perform this direct digital down conversion of a 10.8 MHz intermediate frequency signal, one embodiment of the present invention uses a hard limiter circuit, a sampler circuit and a digital down converter circuit. The hard limiter circuit of the present invention receives a 10.8 MHz intermediate frequency signal, utilized within cell stations and portable station of the personal handy phone system, and provides a threshold for it. The sampler circuit uses a 19.2 MHz oscillating clock signal to sample the intermediate frequency signal that is output from the hard limiter circuit. Due to spectral leakage, the 10.8 MHz intermediate frequency signal that was input into the sampler circuit is output as an 8.4 MHz intermediate frequency signal. The digital down converter circuit uses an 8.4 MHz signal to perform a digital down conversion of the 8.4 MHz intermediate frequency signal into a digital baseband signal. The present invention provides a system that utilizes only one digital down conversion stage to perform a direct digital down conversion of a 10.8 MHz intermediate frequency signal into a digital baseband signal.

摘要： A toner for developing electrostatic images is formed from toner particles containing at least a binder resin, a colorant, and a wax. The binder resin comprises a vinyl polymer component and a polyester component. The binder resin contains 40-99 wt. % of a component A, 0-20 wt. % of a component B, and 0-60 wt. % of a component C, the components B and C providing totally 1-60 wt. % of the binder resin. The component A comprises low- and medium-molecular weight components having molecular weights of below 10.sup.6, and the component B comprises high-molecular weight components having molecular weights of at least 106, respectively, based on a chromatogram obtained by gel permeation chromatography of a tetrahydrofuran (THF)-soluble component of the binder resin, and the component C is a THF-insoluble component of the binder resin. The GPC chromatogram of the THF-soluble component of the binder resin exhibits a main peak in a molecular weight region of 3.times.10.sup.3 -5.times.10.sup.4. The toner particles have a shape factor SF-1 of 100-160 and a shape factor SF-2 of 100-140.

摘要： The present invention relates to a method of producing a plurality sets of prints from a plural-page original in an image forming apparatus having an endless transfer member onto which images are transferred from an image retaining member. The endless transfer member is operable to support a predetermined number (X) of images during one cyclic movement thereof. In this method, a first printing operation is executed in which the predetermined number (X) of images of a first page of the original are formed on the endless transfer member during one cyclic movement thereof when a desired number (Y) of sets of prints exceeds said predetermined number (X). Second, the first printing operation is repeated until a remaining number (M) of image(s) of the first page becomes less than said predetermined number (X). Third, a second printing operation is executed in which the remaining number (M) of image(s) of the first page and a calculated number (X-M) of image(s) of a second page of the original are formed on said endless transfer member during one cyclic movement thereof after the remaining number (M) of image(s) of the first page becomes less than the predetermined number (X).
