A novel soil conditioning rotary reel comprised of a rotary reel having a plurality of flat bars attached to support plates in a symmetrical helix arrangement is disclosed. The number of bars and the diameter of the reel are determined by the limitation that the straight-line distance between two adjacent bars be less than six inches.

According to one embodiment of the invention, a method for probing a wafer includes positioning a testhead relative to a prober supporting a wafer in a testing position. The method also includes receiving at least one prober signal identifying the angular position of the prober and at least one testhead signal identifying the angular position of the testhead. The at least one prober signal and the at least one testhead signal are processed to determine if the testhead is substantially parallel with the prober, and output is provided to allow for adjustment of the position of the testhead in response to determining that the testhead is not substantially parallel with the prober.

Apparatus and methods are described, including identifying a subject as suffering from hypertension. In response to the identifying (a) a radius of curvature of a first set of at least three regions of an arterial wall of the subject is increased at a given longitudinal location, while (b) allowing the first set of regions of the arterial wall to pulsate. A device is implanted inside the artery at the longitudinal location such that the device applies pressure to the arterial wall at a second set of at least three regions of the artery, but does not contact the first set of regions, the first set of regions and the second set of regions alternating with each other. Other embodiments are also described.

An apparatus for sealing a glass package by applying a force to a glass assembly while simultaneously irradiating a sealing material disposed between the two glass substrates with a beam of radiation. The applied force is translated in unison with the radiation beam. The radiation cures and/or melts the sealing material, depending upon the sealing material. The applied force beneficially improves contact between the glass substrates and the sealing material during the sealing process, therefore assisting in achieving a hermetic seal between the substrates.

An ink jet printer includes an ink container supplying ink through a tube member to a separate print head to form an image. The ink jet printer also includes a supporting portion that supports the tube member. As the print head reciprocates in a width direction of a recording medium, the tube member flexes as the print head mounted on a carriage moves. The tube protruding from the print head is inclined at approximately 30 degrees with respect to a moving direction of the print head, toward the supporting portion. When the tube is pulled toward the supporting portion, resistance to the movement of the print head can be restricted. When the tube bends or curves between the supporting portion and the print head, the tube can be moved smoothly toward the supporting portion. Thus, when the print head reciprocates, the tube can flex smoothly and the resistance applied to the print head by the tube can be restricted, allowing proper ink supply to the print head.

Disclosed herein are a stacking type electrode assembly constructed in a cathode/separator anode structure, wherein the electrode assembly is provided at a predetermined region thereof with at least one through-hole, and a pair of holding members (a male coupling member and a female coupling member) constructed in a male-female coupling type structure is inserted through the through-hole inside a battery case, an outer surface of the female coupling member being brought into tight contact with the through-hole when the male coupling member is inserted into the female coupling member while the female coupling member having an outer diameter less than an inner diameter of the through-hole is inserted through the through-hole, and a secondary battery including the same. The electrode assembly according to the present invention has the effect of restraining the cathodes and the anodes from being moved separately from the separators, when an external force is applied to the electrode assembly, thereby preventing the occurrence of internal short circuits, and eventually, improving the safety of a secondary battery including the electrode assembly. Furthermore, the electrode assembly according to the present invention has the effect of restraining the movement of the electrodes due to repetitive contraction and expansion of the electrode assembly during the charge and discharge of the secondary battery.

An umbilical for use in the offshore production of hydrocarbons, and in particular to a power umbilical for use in deep water applications is described, comprising a plurality of longitudinal strength members, wherein at least one longitudinal strength member comprises rope enclosed within a tube. In this way, the or each longitudinal strength member being a rope and tube combination achieves the synergistic benefit of favorable mechanical properties in the axial direction, with favorable mechanical properties in the radial direction during tensioning or the like of the umbilical, especially during installation.

Drying section of a machine for producing a material web, such as a paper or cardboard web, comprises at least one drying group having at least one drying cylinder and at least one web guidance device around which the material web is guided in a meandering manner. The shrinkage gradient that occurs in the material web transversely with respect to the direction in which the web travels is set or controlled by providing at least one, and preferably several, areas in which an at least mostly free, unhindered shrinkage of the material web is possible.
