  • Publication number: 20110207284
    Abstract: A method of at least one embodiment of the present invention of manufacturing a solid-state memory is a method of manufacturing a solid-state memory, the solid-state memory including a recording film whose electric characteristics are varied by phase transformation, the method including: forming the recording film by forming a laminate of two or more layers so that a superlattice structure is provided, each of the layers having a parent phase which shows solid-to-solid phase-transformation, the recording film being formed at a temperature not lower than a temperature highest among crystallization temperatures of the parent phases. It is thus possible to manufacture a solid-state memory which requires lower current for recording and erasing data and has a greater rewriting cycle number.

  • Publication number: 20100315867
    Abstract: A solid-state memory device includes: a superlattice laminate having plural crystal layers laminated therein, the crystal layers including first and second crystal layers having mutually opposite compositions; a lower electrode provided on a first surface in a laminating direction of the superlattice laminate; and an upper electrode provided on a second surface of the superlattice laminate in the laminating direction. The first crystal layer included in the superlattice laminate is made of a phase change compound. According to the present invention, the superlattice laminate laminated in opposite directions of the upper and lower electrodes is sandwiched between these electrodes. Therefore, when an electric energy is applied to the superlattice laminate via these electrodes, a uniform electric energy can be applied to a laminated surface of the superlattice laminate. Accordingly, fluctuation of a resistance is small even when information is repeatedly rewritten, and data can be read stably as a result.

  • Publication number: 20100284218
    Abstract: To include a superlattice laminate having laminated thereon a first crystal layer of which crystal lattice is a cubic crystal and in which positions of constituent atoms are reversibly replaced by application of energy, and a second crystal layer having a composition different from that of the first crystal layer, and an orientation layer that is an underlaying layer of the superlattice laminate and causes a laminated surface of the first crystal layer to be (111)-orientated. According to the present invention, the laminated surface of the first crystal layer can be (111)-orientated by using the orientation layer as an underlaying layer. In the first crystal layer of which laminated surface is (111)-orientated, a crystal structure reversibly changes when a relatively low energy is applied. Therefore, characteristics of a superlattice device having this crystal layer can be enhanced.

  • Publication number: 20100194007
    Abstract: An improved filter assembly for molten metal is described. The assembly has a canister with at least one port wherein the port allows filtered molten metal to flow from the canister. A plurality of filter elements is in the canister wherein the filter elements separate a volume of the canister into a primary chamber and a secondary chamber wherein the secondary chamber is in direct flow communication with the port. A ported cover is over the canister wherein the ported cover prohibits unfiltered molten metal from flowing directly into the secondary chamber. The molten metal flows from the primary chamber to the secondary chamber through a filter element.

  • Publication number: 20070181867
    Abstract: A new class of phase change materials has been discovered based on compounds of: Ga; lanthanide; and chalcogenide. This includes compounds of Ga, La, and S (GLS) as well as related compounds in which there is substitution of S with O, Se and/or Te. Moreover, La can be substituted with other lanthanide series elements. It has been demonstrated that this class of materials exhibit low energy switching. For example, the GLS material can provide an optical recording medium with erasability 3-5 dB greater than the erasability of GeSbTe (GST) material which is the standard material for phase change memories.

  • Publication number: 20070160120
    Abstract: An embodiment generally relates to a method of processing direct-sequence spread spectrum signals for temporal alignment between a received direct sequence spread spectrum (DSSS) signal and a local reference signal. The method includes receiving the received DSSS signal with bandwidth to resolve at least N samples per code chip and de-spreading the received DSSS signal to recover an elemental waveform within the received DSSS signal for an interval greater than one code chip interval as a first processing stage. The method also includes determining a discriminator value based on the elemental waveform as a second processing stage and operating a delay-locked loop based on the discriminator value to adjust an alignment between the received DSSS signal and the local reference signal.

  • Patent number: 7233628
    Abstract: A circuit for receiving multiple serial datastreams in parallel is disclosed. A bit clock is recovered from each data stream, there being one data bit for each transition of the clock signal both positive and negative going. The phases of the bit clocks are compared and are adjusted by 180 degrees so that the positive going edges of all occur close to each other. The bits of each stream are assembled into words under the control of a word clock. In one embodiment a common word clock is derived form the set of bit clocks as a whole. In another embodiment each stream is provided with its own word clock which is aligned to positive edges of the respective bit clocks that are close to each other.

  • Publication number: 20070121708
    Abstract: Embodiments of the present invention pertain generally to methods and systems of processing a global positioning satellite (GPS) signal. More particularly, embodiments of the present invention provide an improved discriminator function that utilizes the early, prompt, and late correlator values. For example, the improved discriminator function may be normalized based on all three of the early, prompt, and late correlator values. The improved discriminator function behaves linearly across a prescribed region whose width depends on the separation between correlators.

  • Publication number: 20070083184
    Abstract: An epidural injection is used in medical procedure to administer medication to a patient's epidural space in the spine, usually to alleviate pain. Although effective in purpose, current medical procedure to administer an epidural injection does contain a flaw that exposes the patient to possible infection, usually manifested as an epidural abscess or bacterial meningitis. A source for infection stems from the manner the epidural catheter, specifically the proximal end not being inserted into the patient, is traditionally handled throughout the procedure—usually freely hanging, susceptible to breaking the sterile field and becoming contaminated. The current invention, an epidural catheter dispenser system, seeks to eliminate this risk of epidural catheter contamination by maintaining the epidural catheter, especially the proximal catheter end, in a sterile dispenser that can be easily manipulated by a physician.
