  • Patent number: 10509357
    Abstract: At the time of an end of an image forming job (YES of S1), a controller causes a blade and a developing roller to be separated from a photosensitive drum (S2). At that time, the controller controls separation timing of the belt and the developing roller so that the developing roller is separated from the photosensitive drum before a surface position of the photosensitive drum contacted to the developing roller at a contact position at the time of a start of separation of the blade from the photosensitive drum reaches a developing position with the separation of the blade. According to this, even when a liquid accumulation reaches the developing position depending on the separation of the blade, the developing roller has already been separated from the photosensitive drum before the liquid accumulation reaches the developing position and therefore, the liquid accumulation is not collected by the developing roller.

  • Patent number: 10416252
    Abstract: A magnetic resonant device includes a receiving antenna, a detune circuit, and an energy harvesting circuit. The detune circuit is coupled to the receiving antenna for switching the receiving antenna between a resonant mode and a non-resonant mode. The receiving antenna in the resonant mode receives a magnetic resonant signal of a magnetic resonant examination. The energy harvesting circuit is coupled to the detune circuit for inducing a harvesting current flowing through the receiving antenna in the non-resonant mode to harvest electric power from the receiving antenna. Advantageously, with this simple and low cost power scheme, traditional cumbersome and expensive DC cablings can be eliminated from the magnetic resonant device.
