摘要： A downsized chip antenna having a large bandwidth ratio is disclosed. The chip antenna has a rectangular prism-shaped base member providing a mounting surface. A conductor is formed inside the base member in such a manner that it is spirally wound around a winding axis, for example, a winding axis parallel to the mounting surface, i.e., in the longitudinal direction of the base member. One end of the conductor is extended to a surface of the base member to form a feeding section, which is connected to a feeding terminal, disposed over the surfaces of the base member to apply voltage to the conductor. In one embodiment, the other end of the conductor is connected to a midway portion of the conductor within the base member, thereby forming a loop in said conductor.

摘要： A chip antenna capable of reducing the spiral pitch of an antenna line to be smaller than that of a conventional one. Conductor patterns are electrically connected sequentially in series through via holes so as to form a spiral antenna line. The antenna line has a winding axis which is arranged either in a zigzag manner or along a straight line. Adjacent wound portions have an equal diameter or width or the adjacent portions may have unequal widths. Since adjacent via holes are arranged in a staggered arrangement with each other, the distance between the adjacent via holes is larger than the spiral pitch of the antenna line, allowing the adjacent portions to be closer together than a conventional chip antenna, thereby allowing the resonance frequency to be reduced.

摘要： The average friction factor between the contact surfaces of a drive roller and an intermediate transfer belt is set to not more than 0.45 and not less than 0.1, and before the primary transfer of the toner image of the last color is finished, a cleaning blade is separated from or comes into contact with the intermediate transfer belt with the drive roller as a backup member. The peripheral length of a photoconductor is greater by not more than 10% than the value obtained by dividing the length on a transfer member necessary for a predetermined image length by an integer n which is not less than 3 and not more than 9, and the ratio between the numbers of rotations of the transfer member and the photoconductor is 1:n.

摘要： An image forming apparatus includes a photoconductor, a developing electrode, at least a magnet disposed in the developing electrode, and a developer. The developing electrode is reciprocally movable against a rotation axis of the photoconductor. Thus, a setting angle of a magnetic pole of the magnet is not varied, even when the developing electrode is moved for cancelling decentering and deflection of the photoconductor and the developing electrode.

摘要： Disclosed is an electrophotographic apparatus capable of producing a high-quality image free from image defects such as fine line dropouts. A photoconductor drum is used that has a magnet mounted therein in immovable fashion. After an electrostatic latent image is formed, the image is brought into contact with magnetic developer in a developer reservoir, causing the developer to be attracted to the photoconductor surface by magnetic force. When the photoconductor drum is rotated past an electrode roller to which an AC voltage is applied, toner is left only in image areas and the latent image is developed into a visible image. A sheet-like sealing member contacting the photoconductor is disposed on the upstream side of the developer reservoir in the rotating direction of the photoconductor drum. A conductive layer is provided on the surface of the sealing member opposite the surface thereof contacting the photoconductor.

摘要： An antenna for receiving electromagnetic waves in a desired frequency band, includes a radiating conductor and a ground conductor, a feeder part, a wavelength-shortening section, and a magnetic field applying section. The radiating conductor and a ground conductor resonate at a resonance point frequency. The feeder part is configured to feed the radiating conductor with electricity. The wavelength-shortening section in which a magnetic body having both a dielectric property and a magnetic property is disposed close to the radiating conductor shifts the resonance point frequency into a band lower than the desired frequency band by a wavelength-shortening effect obtained based on the dielectric property and the magnetic property. The magnetic field applying section is configured to apply a magnetic field to the magnetic body so as to reduce a magnetic loss due to the magnetic body.

摘要： When an image forming apparatus, after a feeding error of a recording material occurs in a fixing device, re-forms on the recording material an image corresponding to image data which image was formed on a sheet which caused the feeding error, an image forming condition is caused to be different from an operation condition used when the feeding error has occurred. This makes it possible to prevent a JAM corresponding to the same image from recurring in the fixing device.
