Title: Method of treating oxide superconductive wires and products using the same
Inventor: HAYASHI NORIKI
IPC: H01L39/24
Filed: 1990-03-29
Granted: 1995-01-31
Abstract: ABSTRACT    In a method of treating an oxide superconductive wire having an oxide superconductive layer formed at least by a step of heating on a tape-type flexible base, for example, with the thermal expansion coefficient of the base being smaller than that of the oxide superconductive layer, the oxide superconductive wire is bent with the oxide superconductive layer positioned inside and the base positioned outside about the flexural center. Accordingly, in the oxide superconductive layer, remaining tensile strain is released based on the difference in thermal expansion coefficient, and degradation of superconductivity of the oxide superconductive layer can be prevented.

Title: A method for killing cells without lysis
Inventor: LAWLIS VIRGIL B JR
IPC: C12P1/00
Filed: 1990-06-13
Granted: 2000-03-21
Abstract: This invention provides a method for killing cells in fermentation processes in order to prepare the fermentation mixture for processing to recover or extract a desired product from the fermentation mixture. A preferred method of this invention comprises adjusting the pH of the fermentation mixture to about 4.75 using a mineral acid, then adding sufficient acetic acid to the mixture to affect a substantially complete cell kill in mixture. A salt of the acetic acid can be used. The organic acid or salt can be added, then the pH adjusted to the desired level. Other organic acids can be used, in which case the pH of the mixture is adjusted to the pKa of the selected organic acid before the organic acid is added to the mixture. The method of this invention is useful for stopping the growth and killing the cells of any microorganism utilized in culture or in fermentation procedures such as those containing yeast, bacteria or fungi. This method is particularly useful in systems where it is desired to kill the cells without lysing them.

Title: Locking cap for medical implants

IPC: A61B17/72
Filed: 1991-08-22
Granted: 2001-10-30
Abstract: A locking cap (10) for anchoring an implanted medical device within a bone (suh as an intramedullary fixation rod (14)) has a cylindrical, helically threaded body, a socket (28) concentrically disposed in one end (22), and an interface (26) for coope-rating with a driving tool, such as a wrench or screwdriver. Once a device such as an intramedullary fixation rod (14) has been implanted within a bone, the locking cap (10) is implanted by being threaded into the bone with a driving tool, its socket (28) en-gaging the near end (12) of the device (14). The socket (28) of the locking cap (10) can be smooth, or it can be threaded so as to thread onto the near end (12) of the device (14) as the cap (10) is threaded into the bone. If threaded, the pitch of the cap's outer threads (16) can exceed the pitch of the inner threads (30) so that the cap (10) advances into the bone more quickly than it adv-ances onto the end (12) of the device (14). Alternatively, the inner thread (30) pitch can exceed, of equal, the outer thread (16) pitch so that the cap (10) advances into the bone more slowly than, or at the same rate as, it advances onto the end (12) of the de-vice (14), respectively.

Granted: 2001-11-20
Abstract: A test system directed to apparatus for transmitting and receiving multiple telephone transmission signals over a single twisted pair (100). The system converts an analog signal from a local switching (112) station to an 80 ksymbols/sec signal for transmission over a twisted pair by a line card (104). A remote terminal (102) converts the 80 ksymbols/sec signal back into a con-ventional analog signal for use in conventional telephone (108), facsimile or other related equipment. The test equipment separ-ately tests the entire system, the line card portion of the system, the remote terminal portion of the system, and the twisted pair. An improved 2-to-4-wire hybrid coupling circuit (202) also is disclosed. The improved circuit has 2 extra "wing" coils attached to the known output transformer, the added coils improving the signal strength of the received signal as well as effectively cancelling out feedback from the output amplifier.

Granted: 2003-05-20
Abstract: In a digital time-shared radio transmission system, a radio receiver receives a signal whose symbol frequency is lower than the channel bandwidth of the system. A correlating and sampling circuit receives a baseband signal, samples the signal eight times with each symbol time, performs channel correlation, generates a channel estimate and samples down the once sampled signal to an observed signal with two values for each symbol time. A channel equalizer executes a fractional viterbi algorithm which utilizes two delta-metric values for each state transition and generates estimated symbols. A channel estimating filter receives a symbol sequence of alternating zero-value symbols .OMEGA. and the estimated symbols and generates an estimated signal. The channel estimating filter is adapted with the aid of an error signal and the filter delivers a channel estimate to the channel equalizer. Weighting factors are generated with the aid of the error signal and the two aforementioned delta-metric values are coweighted to a common delta-metric value with the aid of the weighting factors, this common delta-metric value being used to generate the estimated symbols. The use of the weighting factors improves the metric calculation and enables the channel estimating filter and the channel equalizer to be relatively simple.     The insertion of the zero-value symbols simplifies the generation of the weighting factors and the adaptation of the channel estimating filter.

Abstract: The invention relates to a swing phase control device for an artificial knee joint prosthesis facilitating a natural sequence of movements and capable of reacting to abrupt movements. The swing phase control device consists of a piston and cylinder arrangement (2). There is a first chamber (8) on one side of the piston (12) and a second chamber (17) on the other. Both chambers can be interconnected via a first choke (38, 43). There is a second choke on the outlet side of the second chamber (17) which connects the latter to a fluid tank. The pressure in the second chamber (17) is applied to a control piston. It is designed in such a way that the second choke (32) closes when the pressure in the second chamber (17) reaches a predetermined level. Once the second choke (32) has closed, the elastic pressure in the second chamber (17) reinforces the return movement of the piston (12) in the cylinder, facilitating an abrupt stretching of the leg.

Title: Methods and apparatus for preventing rounding errors when transform coefficients representing a motion picture signal are inversely transformed
Inventor: SUZUKI TERUHIKO
IPC: H04N19/91
Filed: 1994-03-01
Granted: 2003-10-14
Abstract: Mismatch error occur in the local decoder of a MPEG-standard compressor for a motion picture signal, and in an MPEG-standard expander for a compressed motion picture signal. This is because of the lack of a standard for rounding results of *.5 (* is an integer) obtained when a set of transform coefficients resulting from compressing the motion picture signal is inversely orthogonally transformed.   The invention prevents mismatch errors by preprocessing the set of transform coefficients prior to the inverse othogonal transform (15).   The transform coefficients in the set are summed (23A) and the parity (odd or even) of the sum is judged (21). When the parity of the sum is judged to be even, the parity of one of the transform coefficients in the set is inverted (28) to provide a parity-inverted transform coefficient. This makes the parity of the sum odd. Then, when the set of transform coefficients indluding the parity-inverted transform coefficient is inversely orthogonally transformed (15), none of the results of the orthogonal transform will have a value of *.5.
