  • Publication number: 20250053258
    Abstract: An input apparatus includes a casing having an opening on one side in a first direction, a panel at least partly exposed through the opening and configured to receive a touch operation and a pressing operation, a holder supporting the panel and reciprocating together with the panel along with the pressing operation, a board in the casing, a sensor provided on the panel and configured to detect the touch operation, a pressure detecting portion configured to detect the pressing operation, and a connector that is provided on the board and connects to a signal cable extending from the sensor. The holder includes a temporary holding portion that holds the board in a state where the board is movable at least in the first direction relative to the holder. The casing includes a stopper that comes into contact with the board from the other side in the first direction.

  • Patent number: 9708700
    Abstract: The present invention provides a magnesium-lithium alloy having both corrosion resistance and cold workability balanced at high levels, a certain degree of tensile strength, and very light weight, as well as a rolled material and a formed article made of this alloy. The alloy of the invention contains not less than 10.5 mass % and not more than 16.0 mass % Li, not less than 0.50 mass % and not more than 1.50 mass % Al, and the balance of Mg, and has an average crystal grain size of not smaller than 5 ?m and not larger than 40 ?m, and a tensile strength of not lower than 150 MPa or a Vickers hardness (HV) of not lower than 50.

  • Patent number: 8911610
    Abstract: Provided is a safe and efficient method for producing lithium metal which facilitates efficient production of anhydrous lithium chloride without corrosion of the system materials by chlorine gas or molten lithium carbonate, and which allows production of lithium metal by molten salt electrolysis of the produced anhydrous lithium chloride as a raw material. The method includes the steps of (A) contacting and reacting lithium carbonate and chlorine gas in a dry process to produce anhydrous lithium chloride, and (B) subjecting the raw material for electrolysis containing the anhydrous lithium chloride to molten salt electrolysis under such conditions as to produce lithium metal, wherein the chlorine gas generated by the molten salt electrolysis in step (B) is used as the chlorine gas in step (A) to continuously perform steps (A) and (B).

  • Publication number: 20130324821
    Abstract: The diagnostic device disclosed in this application is a device for diagnosing liver condition. The diagnostic device comprises a nitric oxide sensor and an information output unit. The nitric oxide sensor can be brought into contact with hepatocytes making up the liver and detects the concentration of nitric oxide produced by the hepatocytes. The information output unit, based on the nitric oxide concentration detected by the nitric oxide sensor, outputs information for diagnosing the condition of the liver. The information output unit can, for example, output a graph showing the change over time in the nitric oxide concentration detected by the nitric oxide sensor.
