Title: Drive circuits for a magnetic recording device
Inventor: MIYAKE SHIGEKAZU
IPC: G11B5/09
Filed: 1998-06-26
Granted: 2001-03-27
Abstract: A drive circuit for a magnetic recording device is provided in which the stray capacitance and stray inductance of the peripheral wiring of the drive circuit is reduced.  Also, the drive circuit increases the read/write frequency of data and the recording   density   of   the   magnetic   recording   device.          Specifically, the drive circuit contains a write driver, a read preamplifier,  a write predriver,  a read postamplifier,  and a current signal detecting circuit.  The write driver inputs write data and outputs a corresponding writing current to a write head to store information onto a magnetic disk.  The read preamplifier supplies  a bias  current  to  a  read magnetic  head to  sense information  stored  on  the magnetic  disk  and  amplifies  the information as output data.  The write predriver inputs a write data signal via a data signal line and a write mode signal and supplies the write data to the write driver based on the write mode signal.  The read postamplifier inputs the output data and a read mode signal and amplifies the output data to produce a read data signal based on the read mode signal.   The current signal detecting circuit inputs an external  current setting signal via the data signal line and generates a current value signal based on the external current setting signal.

Title: Hardfacing compositions and hardfacing coatings formed by pulsed plasma-transferred arc
Inventor: FANG ZHIGANG
IPC: C22C29/02
Filed: 1999-01-13
Granted: 2008-07-29
Abstract: A new hardfacing composition is disclosed. In addition, a pulsed plasma transferred arc method for depositing hardfacing material with a higher content of carbide and lower dilution by a substrate metal is disclosed. The disclosed method produces a hardfacing coating which has a strong metallurgical bond to the substrate metal. The method includes the following steps: (1) establishing a transferred plasma arc between an electrode and an area of a work piece, (2) optionally preheating the work piece to at least 250°F, (3) forming a plasma column of inert gas in the arc by passing an electrical current between the electrode and the work piece, (4) feeding a stream of hardfacing material in powder form into the plasma column, and (5) pulsing the current between a pre-selected high pulse current value and low pulse current value while feeding the powdered hardfacing material. In this method, the low pulse current is selected to be sufficiently high to melt at least one component of the hardfacing material. The pulse rate and the high pulse current are selected to minimize the formation of a weld pool on the metal substrate during the hardfacing process. This method has applications in hardfacing any metallic work piece which requires wear resistance or erosion resistance. This method is especially effective in hardfacing roller cone surfaces and the milled teeth of a rock bit for erosion and wear protection.

Abstract: Polymeric articles, including membranes, with surfaces having a desired chemical functionality are created by surface segregation of a branched component blended with a compatible, matrix base component, the branched component having the desired chemical functionality. In particular, hydrophilic surfaces are created via surface segregation of a branched hydrophilic copolymer blended into a polymer matrix. The use of branched molecular architecture provides a thermodynamic mechanism for the segregation of the hydrophilic species to the surface and a means for achieving a high surface coverage of the hydrophilic moiety. The branched hydrophilic copolymer can be defined by a random copolymer including two or more methacrylate or acrylate monomers, at least one of which features a short hydrophilic side chain, such as a polyethylene glycol side chain. The branched hydrophilic copolymer is compatible, and well-entangled, with the acrylate polymer matrix.

Patent CA-2266277-C (CA)
Inventor: DAL FARRA DAVID
IPC: H04M1/74
Filed: 1999-03-23
Granted: 2008-11-18
Abstract: The invention relates to an acoustic echo canceller particularly well suited for use in a hands-free terminal or teleconference system. The echo canceller is designed to assess the inherent signal attenuation occurring in the analog loop that connects the terminal to the switch mechanism of the PSTN domain or the PBX domain. The echo canceller is then adjusted in accordance with the degree of signal attenuation manifested by the loop. For high signal attenuation levels, the degree of echo control at the terminal is reduced since the signal attenuation occurring in the loop itself will compensate for the reduction, allowing to reach the echo control target at the far end of the loop (switch side). This feature avoids overly attenuating the echo at the terminal by taking advantage of the inherent echo control provided by the local loop conductors.
