  • Publication number: 20120312261
    Abstract: A phase adjusting mechanism is engaged with a brake shaft, and adjusts a rotation phase between a crankshaft and a camshaft according to a braking torque acting on a rotor. The rotation phase is adjusted in a predetermined direction when the braking torque is increased. A torque input mechanism inputs a return torque into the phase adjusting mechanism to return the rotation phase in an opposite direction opposite from the predetermined direction. The torque input mechanism increases the return torque corresponding to the rotation phase as an environmental temperature of the variable valve timing apparatus is lowered.

  • Publication number: 20110303171
    Abstract: A valve timing controller has a case which defines a fluid chamber therein. A magnetic viscosity fluid is enclosed in the fluid chamber. The magnetic viscosity fluid including magnetic particles and its viscosity varies according to a magnetic field applied thereto. A coil and a control circuit applies magnetic field to the magnetic viscosity fluid to variably control a viscosity thereof. A brake rotor is rotatably accommodated in the fluid chamber and receives a brake torque from the magnetic viscosity fluid according to the viscosity thereof. A phase adjusting mechanism is connected to the brake rotor for adjusting a relative rotational phase between the crankshaft and the camshaft according to the brake torque. When it is estimated that the engine will be started, the coil is energized to generated heat in the magnetic viscosity fluid.

  • Patent number: 7958934
    Abstract: A counter-stream-mode oscillating-flow heat transport apparatus improves heat transport capability by imparting oscillatory displacement to a fluid located near a heat-generating element such that the fluid is directed toward the heat-generating element. Turning portions of serpentine flow paths are disposed to face the heat-generating element. The flow paths are stacked in multiple layers in the direction from the heat-generating element to the flow paths, and a plurality of flow paths are disposed adjacent to the heat-generating element in the direction of fluid oscillation.

  • Patent number: 7665510
    Abstract: The fluid drive unit includes a cylinder communicating with both end portions of a meandering passage formed in the heat transport device. In the cylinder, the piston is slidably arranged being capable of sliding in the axial direction. Fluid is charged in the spaces, which are provided on both sides of the piston, connected to the meandering passage. The solenoid coil, which is provided in the periphery of the side of the cylinder, periodically inverts the magnetic poles and reciprocates the piston in the cylinder. To drive the piston smoothly and reduce the amount of eccentricity, a pair of sliding members are provided at the end portions of the piston. When the fluid in the passage is vibrated by the movement of the piston, the apparent heat conductivity of the heat transport device is enhanced, and heat is quickly diffused from the heating body to the radiating portion.

  • Publication number: 20050022977
    Abstract: A counter-stream-mode oscillating-flow heat transport apparatus accommodates a change in volume of a liquid while preventing reduction in heat transport capability. A flow path and a buffer tank are placed in communication with each other via a throttle such as a capillary tube. This prevents a channel connecting the flow path and the buffer tank from having an excessively reduced channel resistance (flow path resistance). This prevents the fluid in a heat transport device assembly (the flow path) from only going back and forth between the heat transport device assembly and the buffer tank without experiencing liquid (pressure) oscillations in the heat transport device assembly. Accordingly, the liquid in the heat transport device assembly is prevented from being reduced in amplitude of oscillation, thereby preventing degradation in heat transport capability of the counter-stream-mode oscillating-flow heat transport apparatus.
