  • Patent number: 10274870
    Abstract: A developer collection device includes a container, a frame, a first fin, and a second fin. The container has an opening, and contains a developer introduced into the container from the opening. The frame extends in a first axis direction, and is attached, to the container, swingably relative to the container in the first axis direction. The first and second fins are provided in the container, and are attached to first and second base points of the frame, respectively. The first and second fins extend in third and fourth directions from the first and second base points, respectively. The third and fourth directions are directions inclining downward and thereby forming angles that are smaller than ninety degrees relative to first and second directions, respectively. The first direction extends along the first axis direction. The second direction is a direction opposite to the first direction.

  • Patent number: 10241437
    Abstract: An exposure device irradiates a light beam to the photoconductor drum and thereby forms an electrostatic latent image on a photoconductor drum. A developing roller causes toner to adhere to the electrostatic latent image and thereby develops a toner image. A development bias power supply circuit applies a development bias to the developing roller. A direct current detection circuit detects a direct current that flows between the development bias power supply circuit and the developing roller. A control circuit (a) causes the exposure device to form an electrostatic latent image of an adjustment patch for toner density adjustment, (b) measures a value of the direct current at a timing when the developing roller causes the toner to adhere to the electrostatic latent image of the adjustment patch, and (c) performs the toner density adjustment on the basis of the measured value of the direct current.

  • Patent number: 10215566
    Abstract: An oscillator includes a substrate, a detection flap plate which is disposed facing the substrate, and an elastically deformable beam portion which displaceably supports the detection flap plate in a Z axis direction with respect to the substrate, in which the detection flap plate is displaced to the substrate side in a range in which recovery force of the beam portion is larger than the electrostatic force which is formed between the substrate and the detection flap plate. That is, when a boundary at which electrostatic force and recovery force are equal is a pull in critical point, the detection flap plate is displaced within a region above the pull in critical point.

  • Patent number: 10209157
    Abstract: A microelectromechanical sensor (MEMS) package includes a gyroscope and an accelerometer. The gyroscope is located within a low-pressure cavity that is sealed from an external pressure. The accelerometer is located within a cavity, and the seal for the accelerometer cavity is entirely within the gyroscope cavity. Under normal operating conditions, the accelerometer seal holds the accelerometer cavity at a higher pressure than the pressure of the enclosing gyroscope cavity. In the event that one of the gyroscope seal or the accelerometer seal is broken, the gyroscope senses the change in pressure.
