摘要： A method of producing a thin film of an inorganic solid electrolyte having a relatively high ionic conductance is provided. In the method, a thin film made of an inorganic solid electrolyte is formed, by a vapor deposition method, on a base member being heated. The thin film obtained through the heat treatment exhibits an ionic conductance higher than that of the thin film formed on the base member not being heated. The ionic conductance can also be increased through the steps of forming the thin film made of the inorganic solid electrolyte on the base member at room temperature or a temperature lower than 40° C. and then heating the thin film of the inorganic solid electrolyte.

摘要： A sulfide-based inorganic solid electrolyte that suppresses the reaction between silicon sulfide and metallic lithium even when the electrolyte is in contact with metallic lithium, a method of forming the electrolyte, and a lithium battery's member and lithium secondary battery both incorporating the electrolyte. The electrolyte comprises Li, P, and S without containing Si. It is desirable that the oxygen content vary gradually from the electrolyte to the lithium-containing material at the boundary zone between the two members when analyzed by using an XPS having an analyzing chamber capable of maintaining a super-high vacuum less than 1.33×10−9 h Pa and that the oxygen-containing layer on the surface of the lithium-containing material be removed nearly completely. The electrolyte can be formed such that at least part of the forming step is performed concurrently with the step for etching the surface of the substrate by irradiating the surface with inert-gas ions.

摘要： A method of independently producing a negative electrode for a lithium secondary cell having thin films of lithium and a sulfide-based inorganic solid electrolyte begins with a negative electrode base material and an inorganic solid electrolyte source material being removed from closed containers in a chamber space, which is substantially inactive to lithium and insulated from air. The materials are transferred into an adjacent thin film deposition system without being exposed to the air. In the system, the source material is used to form a thin film of an inorganic solid electrolyte on the base material, to make the electrode. The electrode is transferred, without being exposed to the air, into a chamber space, which is substantially inactive to lithium, where the electrode is placed into a closed container. Thus, a negative electrode can be produced without being degraded by air.

摘要： This magnetic sensor comprises a flux transformer 2 having a superconducting thin film 2f formed on a sapphire substrate 2s, and a SQUID 1 disposed on the flux transformer 2 opposite thereto. In this magnetic sensor, since the sapphire substrate 2s, which can be obtained in a large size, is used for the flux transformer 2, even when the SQUID 1 is made smaller, the magnetic flux introduced from the flux transformer 2 into the SQUID 1 can be enhanced so as to increase the effective magnetic flux capturing area, whereby the detecting performance is improved, while the manufacturing cost can be reduced due to the smaller size of the SQUID 1.
