摘要： A chip-like printed antenna in which an open end is formed by at least two antenna conductors separated from each other is mounted on a printed-circuit board. A ground required by one or plural other modules is disposed and mounted on the printed-circuit board so as to surround a remaining area of a surrounding area of the printed antenna except a partial area as indicated by oblique line parts. By this, in the printed-circuit board , a radiation electric field does not come to have a dipole mode, but is formed into a balloon shape and is radiated in one direction as indicated by a broken line.

摘要： A PDA includes a printed-circuit board on which at least one printed antenna pair having two chip-like printed antennas, which receive linearly polarized signals and are disposed along axes orthogonal to each other, is mounted. In each of the printed antennas, an open end is formed of at least two antenna conductors separated from each other. Besides, in the printed-circuit board, a ground required by one or plural other modules is disposed so as to surround a surrounding area of at least three sides of four sides forming a rectangular section in each of the printed antennas, and each of the printed antennas is disposed and mounted so that a remaining one side faces an edge portion of the printed-circuit board. While the PDA can receive circularly polarized signals very effectively, the degree of freedom in layout is greatly expanded and miniaturization can be realized.

摘要： In a fixing apparatus and an image forming apparatus of the present invention, an external heating section is provided that includes: an external heating belt; two heat rollers suspending the external heating belt and pressed against a fixing roller via the external heating belt; and a release/contact mechanism for causing the two heat rollers to separate from or contact with the fixing roller. With the heat rollers separated from the fixing roller by the release/contact mechanism, the external heating belt and the fixing roller are in contact with each other and the external heating belt follows rotation of the fixing roller. As a result, a fixing apparatus is provided that includes an external release/contact mechanism that can quickly operate in a small space and at low power without encouraging deterioration of the belt member. An image forming apparatus provided with such a fixing apparatus is also provided.

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： A helical antenna is provided in which a predetermined resonance frequency can be determined at the design stage. The helical antenna includes a conductor which is formed from copper or a copper alloy inside a base in the shape of a rectangular parallelopiped formed from a dielectric material having barium oxide, aluminum oxide and silica as main constituents and which is wound in a helical shape along the length of the base. In such a case, the resonance frequency f0 of the helical antenna and the inductance components L of the conductor satisfy the relationship: ln (L)=A0+A1.times.ln (f0), where ln is a natural logarithm, and A0 and A1 are constants. One end of the conductor is extended onto the surface of the base and forms a power feeding terminal connected to a power feeding terminal formed on the surface of the base for applying a voltage to the conductor, and the other end thereof forms a free end inside the base.
