Publication number: 20150118747Abstract: An in vitro model system that guides the development of microvasculature, recapitulating the detailed organization of both its cellular and a-cellular components is established. Use of electrostretched fibrin microfibers enables both endothelial layer organization and co-culture of supporting perivascular (mural) cells such as vascular smooth muscle cells and pericytes. The fiber curvature affects the circumferential deposition of endothelial-produced ECM independently of cellular organization and induces deposition of higher quantities of vascular ECM proteins. Further, a luminal multicellular microvascular structure is disclosed.Type: ApplicationFiled: October 31, 2014Publication date: April 30, 2015Inventors: Sharon Gerecht, Shuming Zhang, Sebastian F.

Publication number: 20100290159Abstract: A common tray for HGA comprises a frame, a first inner bar, and a second inner bar parallel to and spaced from the first inner bar. Ends of the first and second inner bars connect to the opposite edges of the frame. A plurality of locating pillars and a plurality pairs of first bumps are uniformly-spaced formed on the first inner bar respectively. The first inner bar has portions between each said pair of first bumps recessed for forming spaces under the HGA. A plurality of second bumps are uniformly-spaced formed on the second inner bar for withstanding an edge of the base plate. The present common tray can replace five kinds of trays traditionally used in the HGA manufacturing process, and thus reduce the load/unload operations as well as the no-value stations and operators, thereby the productive efficiency is improved, and manufacturing cost is reduced.Type: ApplicationFiled: May 18, 2009Publication date: November 18, 2010Applicant: SAE Magnetics (H.K.)

Patent number: 7777991Abstract: A head gimbal assembly (HGA) has an improved interconnection between a head slider and a suspension of the HGA. The interconnection is achieved by using a reverse surface of an air bearing surface of the head slider as bonding surface to provide more space for arranging more slider electrical bonding pads thereon. The head slider is mechanically and electrically connected to the suspension at the bonding surface to have good performance on shocking conditions. The suspension further has an attitude control layer located between the head slider and the suspension. The attitude control layer serves as a datum plate for the head slider lying thereon and supporting the head slider so as to ensure the head slider a good attitude and reduce variation of slider flying height. The present invention also discloses a magnetic disk drive with the improved HGA and a fabricating method for the HGA.Type: GrantFiled: January 12, 2007Date of Patent: August 17, 2010Assignee: SAE Magnetics (H.K.)
