  • Patent number: 10466646
    Abstract: A photosensitive drum is rotatable about a first axis extending in a particular direction. A frame rotatably supports the photosensitive drum. A developing roller is rotatable according to driving force about a second axis extending in the particular direction. A surface of the developing roller contacts a surface of the photosensitive drum through toner. A resistance generating member generates a resistance torque TQ1 serving as resistance between the frame and photosensitive drum in a case where the photosensitive drum rotates relative to the frame. In a case where the developing roller rotates according to the driving force in a state where the surface of the developing roller contacts the surface of the photosensitive drum through toner, the resistance torque TQ1 is smaller than a torque TQ2 that causes the photosensitive drum to rotate due to friction between the surface of the developing roller and the surface of the photosensitive drum.

  • Publication number: 20180266518
    Abstract: A second rotor and a third rotor are accommodated in a first rotor. A fitting portion of the third rotor is located in an engagement hole of the second rotor to engage the third rotor with the second rotor. The third rotor is rotational about an axis, which is eccentric to an axis of the first rotor, to vary a relative rotational phase of the first rotor to the second rotor and to accelerate and decelerate rotation of the second rotor. When friction arises between the second rotor and the fitting portion, a frictional force acts in a direction to reduce a rotational moment acting on the third rotor. A friction coefficient between the second rotor and the fitting portion is greater than a friction coefficient between ferrous objects.

  • Patent number: 10030612
    Abstract: A fuel injection system includes a first injection valve, a second injection valve, a communication pipe, and an ECU. The communication pipe makes a second passage of the second injection valve and a back pressure chamber of the first injection valve communicate with each other. The ECU controls an electric actuator of the second injection valve so as to switch first injection control and second injection control according to the required injection amount. In the first injection control, a second valve body is opened for a predetermined time or more so that back pressure lowers to the pressure of opening a first valve body. In the second injection control, the second valve body is opened for less than the predetermined time so that the back pressure does not lower to the pressure of opening the first valve body.

  • Patent number: 9670880
    Abstract: A gaseous fuel feed apparatus includes a first injector and a second injector which are provided in each cylinder of a gas engine. The first injector injects a gaseous fuel into an intake passage. The second injector injects the gaseous fuel in an injecting direction intersecting with an injecting direction of the gaseous fuel injected by the first injector, such that the gaseous fuel injected by the second injector collides with the gaseous fuel injected by the first injector. Thus, the gaseous fuel injected by the first injector can be forcibly pressed toward a flow of an air by utilizing an injection energy of the gaseous fuel injected by the second injector. Further, the first injector and the second injector may be placed at the same position of the intake passage, and can be placed at a position of the intake passage that is adjacent to a combustion chamber.
