  • Patent number: 4978998
    Abstract: An image transferring device for use in image forming equipment prevents an image from being omitted in a trailing edge portion of a paper sheet in the event when pre-transfer discharge is applied to a photoconductive element prior to image transfer. The pre-transfer discharge is not effected on an image portion of a photoconductive element that is associated with a trailing edge portion of a paper sheet where a discharge due to separation will be caused by the vibration of the trailing edge portion of the paper sheet.

  • Patent number: 4903333
    Abstract: Disclosed is here an apparatus for automatically adjusting a length of the antenna of the radio receiver in which the antenna is disposed to be integral with a high-frequency circuit section and a tuning circuit is configured to be in a variable capacity system. The apparatus includes a unit for detecting a condition that an intensity of an antenna input electric field is at least an optimal range so as to generate a first signal, a unit for detecting a condition that the intensity of the antenna input electric field is at most an optimal range so as to generate a second signal, a unit for detecting a condition that an interference signal is at least at a predetermined level so as to generate the second signal, a device for elongating the antenna based on the first signal, and a device for shortening the antenna based on the second signal.
