  • Shock absorber
    Patent number: 9695898
    Abstract: A damping force generating apparatus of a shock absorber includes a main flow path through which a working fluid flows, a main valve which generates a damping force by controlling the flow of the working fluid by opening and closing the main flow path, a pilot chamber into which the working fluid branched from the main flow path flows and which applies an internal pressure in a valve closing direction to the main valve by a pressure of the working fluid, and a pilot flow path to which the working fluid flows out from the pilot chamber. In addition, a jet stream which is generated in a flow path narrowed by the main valve in the main flow path joins the flow of the working fluid which flows out from the pilot chamber via the pilot flow path.

  • Imprint method, imprint apparatus, and article manufacturing method
    Patent number: 9566741
    Abstract: An imprint method of forming a pattern of a resin on a substrate held on a holding surface. An uncured resin on the substrate is brought in contact with a mold. A partial region of the substrate is thermally deformed by irradiating the region with light so as to change an outer circumferential shape of the region. The uncured resin is cured on the region by irradiating light having a wavelength different from the deforming light. The mold is released from the cured resin on the region in contact with the mold. In at least a portion of a period during the deforming step, a region different from the region is held at a first suction force, while the region is held at a second suction force less than the first. The first suction force and the second suction force act between the substrate and the holding surface.

  • VEHICLE HEIGHT ADJUSTMENT DEVICE
    Publication number: 20170036503
    Abstract: In a vehicle height adjustment device, an operation amount of an actuator increases in accordance with supplied current, a detector detects a vehicle height, and a changer changes the vehicle height in accordance with the operation amount of the actuator. The changer shifts to a vehicle height increasing state or to a vehicle height decreasing state based on whether the operation amount is not higher than a predetermined amount. A controller controls the current supplied to the actuator to make the relative position have a target value. The controller determines a target current supplied to the actuator based on a control map that correlates a deviation between the target value of the relative position and a detection value to the target current.

  • VEHICLE HEIGHT ADJUSTMENT DEVICE
    Publication number: 20170021688
    Abstract: A vehicle height adjustment device includes an actuator, a detector, and a controller. The actuator is driven when supplied with a current and is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The detector is configured to detect the relative position. The controller is configured to control the current supplied to the actuator to make the relative position a target value so as to adjust a vehicle height of the body. When a detection value of the detector is smaller than the target value of the relative position, the controller is configured to alternately supply an increase current and a maintenance current to the actuator. The increase current increases the relative position to increase the vehicle height. The maintenance current maintains the relative position to maintain the vehicle height.

  • Shock absorber
    Patent number: 9550545
    Abstract: A shock absorber includes: a valve body; a valve seat; an actuator; and a fail-safe valve that is urged by a first elastic body. When fluid does not flow, the fail-safe valve is urged by the first elastic body to come into contact with the valve body and close a channel. When the fluid flows, the fail-safe valve is spaced from the valve body by a fluid pressure to open the channel. When the valve body moves most in a valve opening direction, the fail-safe valve is brought into contact with the valve body and the channel is closed, and a supporting portion supports a part of the fail-safe valve. When the fluid flows in this state, at least a part of the fail-safe valve, which is in contact with a non-supporting portion, is spaced from the valve body by the fluid pressure to open the channel.
