Inventor: MOON RONALD R
IPC: G11B5/596
Filed: 1992-06-02
Abstract: A method and apparatus are provided for recovering servo information in a disk drive for positioning a data transducer head relative to concentric data tracks wherein the head reads user data encoded in a predetermined data code and reads servo information within plural servo sectors embedded in each data track defined on a storage surface of a rotating disk. The data tracks are arranged in plural groups of concentric tracks within concentric zones wherein each zone has a user data transfer rate selected in relation to disk radius, the servo information being recorded in at least three patterns within each embedded servo sector: a servo sync pattern, a user data code violating pattern, and a servo data bit pattern. A servo data recovery circuit implements the method comprising the steps of: 
   timing expected arrival of a servo sector with a sector timer, 
   at the expected arrival of the servo sector detecting a said servo sync pattern with a servo sync pattern detector, 
   detecting at least one said user data code violating pattern with a user data code violating pattern detector, 
   detecting recurrent servo data bit patterns as binary data bits with a data reader, 
   determining presence of a servo address mark with a master state machine following detection of said at least one user data code violating pattern, 
   upon detection of a servo address mark, restarting said sector timer, 
   accumulating within the master state machine the detected binary data bits in order to detect a track identification number, and 
   providing the track identification number to a head position servo loop for use in positioning the head relative to the data tracks during track seeking operations of the disk drive. The data reader forms an independent aspect of the present invention.

Abstract: An infusion sleeve for an ultrasonic tissue removal surgical tool includes a sleeve designed to surround the ultrasonically driven tip of the surgical tool and create an irrigation fluid channel thereinbetween. The sleeve includes a flexible portion which permits retraction of the distal end thereof to permit contact between the tip of the surgical tool and body tissue to be destroyed or removed. The infusion sleeve also includes a rigid portion which is designed to prevent collapse of the sleeve around the ultrasonically driven surgical tip and prevent blockage of irrigating fluid flow and subsequent overheating of the tip and damage to adjacent body tissue.

Abstract: In a sidelobe canceller, a main channel multiplier (11) operates on the baseband output signal of a main antenna (10) with a weight signal to produce a weighted main channel signal. The baseband output signals of auxiliary antennas (16₁∼16 n ) are adaptively weighted so that the auxiliary antennas have a first directivity pattern (44) whose main lobe oriented toward an undesired signal and summed togeher to produce a first sum signal (y s ), and further adaptively weighted so that the auxiliary antennas have a second directivity pattern (45) whose main lobe is oriented toward a desired signal, and summed together to produce a second sum signal (y d ). The second sum signal (y d ) is summed with the weighted main channel signal to produce a diversity combined signal (y c ), and the first sum signal (y s ) is subtracted from the diversity combined signal (y c ) to produce a sidelobe cancelled signal (y z ). An adaptive equalizer (14) is provided for removing intersymbol interference from the sidelobe cancelled signal (y z ). The main channel weight signal is derived by correlating the output of the adaptive equalizer with the output of the main antenna.

Abstract: The invention concerns a process for the formation of an electroless copper deposit from a plating bath comprising an aqueous solution containing a copper compound, a complexing agent for copper, a reducing agent for copper, a pH-adjusting agent, an additive selected from the group consisting of soluble inorganic silicon compounds and soluble inorganic germanium compounds, and in which process an oxygen containing gas is injected into the solution. Electrolessly deposited copper with improved properties of smoothness and elongation is obtained by controlling one or more of the plating bath parameters pH, complexing agents, sources of iron so as to limit the content of trace iron in the deposited copper layer to a value below 1.5 mg per mole of copper. Printed wiring boards manufactured in accordance with the invention display improved resistance to thermal stress and thermal cycling of copper plated-through holes. The achieved improvements are enhanced by the addition of vanadium to the plating bath.

Abstract: A method of assaying analytes using a rate procedure is described where the change in density over time has a variable rate. The method features the steps of depositing the sample on to a dried slide-like test element, making an initial rate reading during an early time window, using the initial rate readings in a comparison study with rates from known low and high concentration results to predict whether the sample rate will be sufficiently low as to be ascertainable during a later time window or not, and then calculating a rate of reaction and concentration during either the early time window or the early time window with a portion of the later time window respectively. To avoid the possibility of a consistent bias, the initial rate readings are used directly in the comparison study without first calculating a concentration, by comparing the initial rate reading of a sample against known rates corresponding to samples with low and high concentrations to determine the length of the time window to be used in the rate calculation.

Abstract: This invention prevents terminals 4 and 5 from being abraded or ground at contacting portions due to vibrations. An end of a male terminal 5 is secured in a part of a stepped hole 16 in a rear wall portion 12 and the other end of the terminal 5 is coupled to a female terminal 4. Even if the female terminal 4 is displaced due to vibrations in a coupled position relative to the male terminal 5, the male terminal 5 can elastically deflect in another part of the stepped hole 16 in accordance with a displacement of the female terminal 4. Consequently, an abnormal contacting pressure caused by vibration at contacting portions of the male and female terminals 5 and 4 can be absorbed to reduce wear or abrasion between them.
