  • Publication number: 20120231298
    Abstract: A method of forming a perpendicular magnetic recording medium. The perpendicular magnetic recording medium comprises a substrate, an underlayer on the substrate, an intermediate layer on the underlayer and a recording layer on the intermediate layer. The underlayer comprises a first soft underlayer, an antiferromagnetically coupled Ru layer on the first soft underlayer, a second soft underlayer on the antiferromagnetically coupled Ru layer, and an orientation control layer on the second soft underlayer, the method comprises applying a negative bias voltage to the substrate during formation of the underlayer.

  • Publication number: 20120115755
    Abstract: A microfluidic device may employ one or more sorting stations for separating target species from other species in a sample. The separation is driven by magnetophoresis. A sorting station generally includes separate buffer and sample streams. A magnetic field gradient applied to the sorting station deflects the flow path of magnetic particles (which selectively label the target species) from a sample stream into a buffer stream. The buffer stream leaving the sorting station is used to detect or further process purified target species labeled with the magnetic particles.

  • Publication number: 20110281560
    Abstract: One embodiment of the present invention provides a system for facilitating cost-optimized mobile messaging. During operation, the system receives an encoded text message at a mobile device. Next, the system replaces a sub-string in the encoded text message with a corresponding sub-string from a data-dictionary to create a decoded text message. Finally, the system displays the decoded text message on the mobile device. Note that this helps to reduce costs since small sub-strings in the encoded text message can be replaced with large sub-strings in the decoded text message, thereby allowing a larger message to be sent via the SMS protocol without sending as many characters.

  • Patent number: 7823479
    Abstract: A vehicle steering column structure includes a movable steering column portion, a tilting mechanism and a telescoping mechanism. The tilting mechanism is configured to selectively adjust an angle of inclination of a tilting part. The telescoping mechanism adjusts the telescopic position of a telescoping part. The telescoping mechanism includes a hand operated release member, an actuation member and a biasing member. The hand operated release member has an actuating end pivotal about first pivot axis between a locking orientation and a releasing orientation. The actuation member has a contact section. The biasing member urges the actuation member to apply an approximately constant return force from the contact section to the actuating end biasing the hand operated release member to return to the locking orientation regardless of the tilt angle of the tilting mechanism.

  • Patent number: 7770487
    Abstract: A vehicle steering column structure includes a fixed steering column portion, a movable steering column portion movably coupled to the fixed steering column portion and a steering column positioning mechanism. The steering column positioning mechanism is operably coupled between the fixed and movable steering column portions for adjusting a relative position therebetween. The steering column positioning mechanism includes a release member and a biasing member. The biasing member biases the release member to a locking orientation such that the biasing force of the biasing member applied to the release member changes with corresponding movement of the release member along a first movement portion of a prescribed movement range and the biasing force of the biasing member is generally constant with movement of the release member along a second movement portion of the prescribed movement range.

  • Publication number: 20100159286
    Abstract: Disclosed is a perpendicular magnetic recording medium on a substrate. The perpendicular magnetic recording medium has a recording layer. The recording layer includes a first granular recording layer and a second granular recording layer. There may be an exchange layer between the first granular recording layer and the second granular recording layer. Additionally or alternatively, the ratio of saturation magnetization of the first granular recording layer and the second granular recording layer may be greater than 1 and/or the first granular recording layer may have a relatively high magnetic anisotropy compared to the second granular recording layer magnetic anisotropy. A forming method is also disclosed.
