The fluid filling system of the present invention includes a fluid storage tank to store fluid therein, a vacuum vessel to receive a hydrodynamic bearing therein, a fluid dispenser for connecting the fluid storage tank to the vacuum vessel and dripping the fluid into a micro-gap of the hydrodynamic bearing, a pump connected both to the fluid storage tank and to the vacuum vessel and separately exhausting air from both the fluid storage tank and the vacuum vessel to the outside, and a nitrogen storage tank for separately controlling pressure in both the fluid storage tank and the vacuum vessel, wherein the fluid storage tank is pressurized using nitrogen such that the pressure in the fluid storage tank becomes higher than the pressure in the vacuum vessel, thus causing the fluid to move to the vacuum vessel and to be dripped into the hydrodynamic bearing received in the vacuum vessel.

  • Publication number: 20080276755
    Abstract: A gear comprised of a tooth surface and a hard carbon film formed on at least a part of the tooth surface. When the gear is used in lubricant including a specific component, a friction of a tooth surface of the gear is largely decreased, and therefore the gear performs an excellent power transmission efficiency. Further, when the gear is employed in a planetary gear mechanism or speed reducing mechanism which has a plurality of meshing portions of gears, the power transmission efficiency of the mechanism is also improved.

  • Publication number: 20080210587
    Abstract: A lubricating pack specifically designed for paper shredders, including a piece of oiled paper saturated with lubricant placed between two jackets that are each provided at an inner layer thereof with an oil-seepage-proof film. The two jackets are then formed with a first seal sealed around their peripheries to form a lubricating pack having a laminating construction. The lubricating pack is fed into the paper shredder through a paper inlet to the paper shredder under auto mode to be shredded by the paper shredder. Accordingly, the cutting blades of the paper shredder would be able to contact the lubricant contained in the oiled paper during the process of shredding the lubricating pack, so as to provide lubrication between cutting blades of the paper shredder thereby extending the lifespan of the paper shredder.

  • Publication number: 20080135340
    Abstract: A fluid reservoir assembly having a pan defining a drain opening and a plug disposed therein is disclosed. The pan includes a pair of ramps disposed on an inner surface thereof adjacent the drain opening. The plug includes a pair of wings in engagement with the ramps. The ramps increase in height relative to the inner surface of the pan along a first direction of rotation about the central axis. The plug is drawn into sealing engagement with an outer surface of the pan by rotating the plug in the first direction of rotation about the central axis thereby moving the wings up the ramps. The pan includes at least one stop to prevent over-rotation of the plug. The ramps define a recess to secure the wings in a closed position.

  • Patent number: 7166561
    Abstract: Paper shredders are maintained using lubrication substrates that have been treated with or that carry a lubricant. The lubrication substrate is fed through the shredding mechanism of a paper shredder. Rather than requiring disassembly of the paper shredder, maintenance and lubrication can be performed by passing the lubrication substrate through the shredding mechanism. The lubrication substrates can take any of a variety of forms, such as a tissue that is encased in a cellophane or plastic envelope and is impregnated with oil. The lubrication substrates can instead have an array of small tubes that carry oil. In another example, the lubrication substrates can take for them of a bubble sheet that carries oil within the bubbles.

  • Patent number: 7134419
    Abstract: Methods and apparatus to flush residual used oil from the lubrication system of an engine during an oil change. The method includes draining used oil from a tank of the lubrication system and then adding fresh oil to the tank. An adaptor or fitting is used to provide an outlet in the lubrication system to flush any residual used oil that may not have been drained along with used oil in the oil tank. The engine may be started such that a scavenging pump of a lubrication system pumps residual used oil out of the system through the outlet. Once a user observes that residual used oil has been substantially flushed from the system, the engine is stopped to terminate the flushing process.
