  • Patent number: 9093857
    Abstract: When the charge level of a fully-charged rechargeable battery decreases due to quiescent power drain, in order to recharge it is necessary for the user to pick up and again place the mobile device in which the rechargeable battery is inserted onto a charging apparatus and issue instructions to start recharging. To address this issue, a charging controller applies control to disconnect a capacitor from a receiver coil with a switch in the case where the charge level of a rechargeable battery is equal to or greater than a given threshold value, and additionally applies control to connect the capacitor to the receiver coil with the switch in the case where the charge level of the rechargeable battery is less than the threshold value.

  • Publication number: 20150206732
    Abstract: Provided are an ion source, an ion gun, and an analysis instrument, which are capable of performing sputtering without damage to a surface of a sample and improving detection sensitivity in mass spectroscopy. In the ion source, an emission opening to which ionization liquid is supplied is disposed in an electric field formed in vacuum environment by an extracting electrode so that super large droplet cluster ions are generated from the emission opening. When the sample is irradiated with a super large droplet cluster ion beam, the sample surface is subjected to sputtering without damage, so as to remove contamination substances or to expose a new surface of the sample. In mass spectroscopy, detection sensitivity is improved.

  • Publication number: 20110064198
    Abstract: The object of the present invention is to analyze a functional organic compound with high accuracy. In the present invention, cluster ions are accelerated so that the kinetic energy of cluster ions is less than 3.1 eV per one atom that makes up the cluster ion and the cluster ions enter a sample. Since the functional organic compound in the sample is etched without the breakdown of the chemical structure, the functional organic compound, which has not been chemically denatured, is exposed on the surface of the sample. By alternately performing the etching and the surface analysis of the sample, or performing the surface analysis of the sample while performing the etching, the sample can be accurately analyzed in the depth direction.
