  • Patent number: 7687216
    Abstract: A two-component developer is provided in which the reduction of the hot offset occurrence temperature due to detachment of the coating layer, image density insufficiency, image fogging and toner scattering and the like can be suppressed. In the two-component developer including a toner and a carrier, the content of acrylic resin in a coating layer of the carrier is in a range from 5 to 50% by weight based on the total amount of the coating layer, and the dielectric loss (tan ?) is in the range from 4.0×10?3 to 15.0×10?3. By using the two-component developer, the reduction of the hot offset occurrence temperature in a fixing apparatus can be prevented. Further, image density insufficiency, image fogging and toner scattering and the like can be suppressed, with a result that images having high quality and sufficient image density can be obtained.

  • Patent number: 7690009
    Abstract: An electromagnetic field generating element restrains magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for thermally assisted magnetic field recording/reproduction using a near field. An information recording/reproducing head and an information recording/reproducing apparatus carry out high frequency magnetic recording/reproduction. The electromagnetic field generating element includes: (i) a substrate, (ii) conductors each provided on the substrate and each serving as a supporting section, (iii) a plate-like-shaped conductor provided on the conductors and (iv) a semiconductor laser element provided on the substrate. The semiconductor laser element irradiates laser light to the plate-like-shaped conductor substantially parallel to an extending flat surface of the plate-like-shaped conductor. This causes generation of a near field in the plate-like-shaped conductor.

  • Patent number: 7688302
    Abstract: A shift register includes plural stages of flip-flops. The last-stage flip-flop Fn and the flip-flop Fn?1 that is the preceding flip-flop thereof are reset by inputting thereto an output signal from the last-stage flip-flop. A delaying means is provided, between an output terminal Q of the last-stage flip-flop for outputting the output signal and an input terminal R of the last-stage flip-flop for receiving the output signal, for delaying an input of the output signal to the input terminal R. The flip-flop Fn is reset at same time or after the preceding flip-flop Fn?1 is reset. With this arrangement, it is possible to prevent malfunctions of circuits due to a failure to reset the flip-flops.
