  • Patent number: 11081683
    Abstract: A method for predicting the likelihood of coagulation of active material particles contained in a slurry for electrode preparation includes measuring rheological properties before and after the slurry is subjected to a shear. The estimation method enables a prediction of filter clogging with a slurry, and thus makes it possible to estimate the likelihood of filter clogging with a slurry without passing the slurry directly through the filter, thereby improving the efficiency of a battery manufacturing process.

  • Patent number: 11070190
    Abstract: The disclosed technology generally relates to packaging a quartz crystal, and more particularly to bonding a quartz crystal using sintering silver paste. In one aspect, a method of packaging a quartz crystal comprises attaching a quartz crystal to a package substrate using one or more silver paste layers comprising silver particles. The method additionally comprises sintering the silver paste in a substantially oxygen-free atmosphere and at a sintering temperature sufficient to cause sintering of the silver particles. The sintering is such that the quartz crystal exhibits a positive drift in resonance frequency of the quartz crystal over time. The method further comprises hermetically sealing the quartz crystal in the package substrate.

  • Patent number: 10829838
    Abstract: The present invention addresses the problem of providing a novel, sold metal alloy. Provided is a metal alloy containing two or more types of metal, wherein an equilibrium diagram of the metal alloy shows the two or more types of metal in a finely mixed state at the nanolevel in a specific region where the two types of metal are unevenly distributed. This metal alloy has a substitutional solid solution of the two or more types of metal as the principal constituent thereof. This metal alloy is preferably one obtained by precipitation after mixing ions of two or more types of metal and a reducing agent in a thin-film fluid formed between processing surfaces, at least one of which rotates relative to the other, which are arranged so as to face one another and are capable of approaching and separating from one another.
