  • Method and apparatus for LWD shear velocity measurement
    Publication number: 20050078555
    Abstract: The logging tool of this invention includes a transmitter conveyed on a drilling collar for exciting a quadrupole signal in a borehole being drilled by a drill bit and a receiver for receiving the signal. The transmitter is operated at a frequency below the cut-off frequency of the quadrupole collar mode. The received signal consists primarily of the formation quadrupole mode which, at low frequencies, has a velocity that approaches the formation shear velocity. The transmitter, in one embodiment, consists of eight equal sectors of a piezoelectric cylinder mounted on the rim of the drilling collar. The value of the cut-off frequency is primarily dependent on the thickness of the drilling collar. Alternatively, the transmitter may be operated to produce both the collar mode and the formation mode and a processor may be used to filter out the collar mode.

  • Thick film magnetic nanopaticulate composites and method of manufacture thereof
    Publication number: 20050074600
    Abstract: Thick film magnetic/insulating nanocomposite materials, with significantly reduced core loss, and their manufacture are described. The insulator coated magnetic nanocomposite comprises one or more magnetic components, and an insulating component. The magnetic component comprises nanometer scale particles (about 1 to about 100 nanometers) coated by a thin-layered insulating phase. While the intergrain interaction between the immediate neighboring magnetic nanoparticles separated by the insulating phase provides the desired soft magnetic properties, the insulating material provides high resistivity, which reduces eddy current loss.

  • Ink cartridge for a printer
    Publication number: 20050068387
    Abstract: The ink cartridge comprises a cartridge body with an ink chamber. On one side of the cartridge body is provided an ink supply port, and an air channel is positioned on the opposite side. The ink chamber is composed of a main chamber and a communicating sub-chamber, and ink-out inspection prism being provided close to the communicating portion. A check valve through which the sub-chamber is communicated with the ink supply port is provided sideways between the sidewalls adjacent to the ink supply port. In this invention, the nominal volume of each ink cartridge is increased, and there is no such problem that a certain amount of ink continues to be fed after the ink-out indicative signal being sent out in case of no porous material. Further, the technical solution of the sideways-provided check valve improves the manufacturability and the ink supply stability.

  • Slider fabrication system for sliders with integrated electrical lapping guides
    Publication number: 20050070206
    Abstract: A slider is described with a resistive electro-lapping guide (ELG), which is aligned with a structure in the write head such as the throat height or trailing shield thickness and extends from the lapping region through the ABS and is connected to pads on the surface of the slider. In a second embodiment the ELG is disposed entirely in the section of the slider which will be removed by lapping. Another embodiment of the invention is a system for single slider lapping which simultaneously monitors the resistance of the read sensor or a read head ELG and at least one ELG that is aligned with a structure in the write head. A controller uses the resistance information to implement an algorithm which decides when lapping should be terminated.
