  • Patent number: 7699626
    Abstract: An electrical connector (1) includes an insulative housing (2) defining a mating face (200) thereof. First and second terminals (3, 4) have the same-length received section (30, 40) in the respective passageways, and a leg section (31, 41), wherein the received section (40) of the second terminal (4) extends much closer to the mating face (200) than that of the first terminal (3). The leg section (41) of the second terminal (4) has a transition section (411), and a tailing section (410) located with a same distance away from the mating face (200) with that of the first terminal (3). This configuration of the first terminals (3) and the second terminals (4) can be set on a same carrier tape (6) to be assembled onto the insulative housing (2) in a common working procedure, which will reduce the operation time and manufacturing costs.

The method comprises: forming a bottom electrode; depositing a nanocrystalline PCMO layer; depositing a polycrystalline PCMO layer; forming a multi-layer PCMO film with bipolar switching properties; and, forming top electrode overlying the PCMO film. If the polycrystalline layers are deposited overlying the nanocrystalline layers, a high resistance can be written with narrow pulse width, negative voltage pulses. The PCMO film can be reset to a low resistance using a narrow pulse width, positive amplitude pulse. Likewise, if the nanocrystalline layers are deposited overlying the polycrystalline layers, a high resistance can be written with narrow pulse width, positive voltage pulses, and reset to a low resistance using a narrow pulse width, negative amplitude pulse.

  • Publication number: 20090327181
    Abstract: Disclosed is a behavior-based method which uses each rater's rating behaviors as the criterion to judge unfair ratings. A behavior refers to the action that a rater gives certain rating under specific context. The behavior-based method regards the rating given by a rater with abnormal behavior as an unfair rating, where abnormal behavior is recognized by comparing a rater's current behavior with his behavior history.

  • Patent number: 7625595
    Abstract: A method of monitoring synthesis of PCMO precursor solutions includes preparing a PCMO precursor solution and withdrawing samples of the precursor solution at intervals during a reaction phase of the PCMO precursor solution synthesis. The samples of the PCMO precursor solution are analyzed by UV spectroscopy to determine UV transmissivity of the samples of the PCMO precursor solution and the samples used to form PCMO thin films. Electrical characteristics of the PCMO thin films formed from the samples are determined to identify PCMO thin films having optimal electrical characteristics. The UV spectral characteristics of the PCMO precursor solutions are correlated with the PCMO thin films having optimal electrical characteristics. The UV spectral characteristics are used to monitor synthesis of future batches of the PCMO precursor solutions, which will result in PCMO thin films having optimal electrical characteristics.
