  • Patent number: 7438476
    Abstract: A hydraulic dynamic bearing has a rotor comprised of a flanged shaft having a thrust ring portion and a cylinder portion, a hub attached to the flanged shaft, and a rotor magnet attached to an inner peripheral face of a skirt portion of the hub. A stator rotatably supports the rotor and comprises a bearing sleeve to which are attached stator coils, and a stator base plate that supports the sleeve. A gap exists between confronting surfaces of the flanged shaft and the bearing sleeve, and lubricating oil is sealed in the gap. Thrust dynamic pressure generating grooves are formed in one or both faces of the thrust ring, and the grooves are in the form of a herringbone pattern having radial inner groove sections and outer groove sections. The depth of the inner groove sections is shallower than that of the outer groove sections, and the depths of both groove sections are constant.

  • Patent number: 7400616
    Abstract: A plurality of data packets that contain sequence numbers, respectively, are transmitted simultaneously between two STAs by using a wireless channel and MIMO. An STA receiving the plurality of data packets transmitted simultaneously by using MIMO generates a single ACK packet containing information that corresponds to a sequence number of each data packet successfully received, and transmits the single ACK packet to a transmit-side STA without using MIMO. Thus, a ratio of successful ACK packet receptions to total receptions can be increased. An effect of improving throughput achieved by simultaneous transmission can also be ensured.

  • Publication number: 20070296940
    Abstract: A method of pattern forming includes forming a resist film on a substrate, transferring a pattern onto the resist film by an immersion lithography method using a liquid immersion fluid to form a latent image on the resist film, conducting a first inspection to inspect whether or not the liquid immersion fluid remains on the resist film after said forming the latent image, developing the resist film after the first inspection, and performing predetermined processing when residual of the liquid immersion fluid is found in the first inspection.

  • Publication number: 20070253651
    Abstract: [Problem] In a hydraulic dynamic bearing comprising a flanged shaft having a thrust ring portion and a cylinder portion, a single bag-like stepped sleeve, a presser ring and a lubricating oil sealed in a fine gap including a thrust gap formed between these bearing constituting members, the lubricating oil in a thrust dynamic pressure generating groove is prevented from being subjected a negative pressure in the vicinity of an inlet. [Means for Resolution] In case of a spiral pattern, the thrust dynamic pressure generating groove G2 is formed such that its depth becomes gradually deep from a side at which a flow velocity of the lubricating oil flowing through the thrust gap is low toward a side at which it is high. Further, in case of a herringbone pattern, the thrust dynamic pressure generating groove G2 is formed such that its depth becomes shallow in an inner peripheral face side than a return point R of the pattern and deep in an outer peripheral face side. An optimum groove depth ratio is 0.6 to 0.7.

  • Patent number: 7191806
    Abstract: The opening of an oil container 11 for storing oil 12 is sealed airtight with a cover member 32. A one-sided-bag-shaped fluid dynamic pressure bearing 10 is seated on an O-ring 25 and fixed airtight onto the upper surface of a bearing seating 30. Inanexhaust position with the distal end portion of an injection tube 36 positioned away from an oil level, the inside of the oil container 11 is evacuated by a vacuum pump 22 through a suction/exhaust passage including a suction/exhaust through-hole 17, thus turning the inside of the one-sided-bag-shaped fluid dynamic pressure bearing (10) into a vacuum. In this state, a control device drives a moving device to raise the oil container 11 to an injection position and releases the suction/exhaust passage to the atmosphere. This causes the oil 12 to be injected into the one-sided-bag-shaped fluid dynamic pressure bearing 10 through an oil injection passage including the injection tube 36.
