  • Publication number: 20180351138
    Abstract: A surface-treated steel sheet for a battery container, including a steel sheet, an iron-nickel diffusion layer formed on the steel sheet, and a nickel layer formed on the iron-nickel diffusion layer and constituting the outermost layer, wherein when the Fe intensity and the Ni intensity are continuously measured from the surface of the surface-treated steel sheet for a battery container along the depth direction with a high frequency glow discharge optical emission spectrometric analyzer, the thickness of the iron-nickel diffusion layer being the difference between the depth at which the Fe intensity exhibits a first predetermined value and the depth at which the Ni intensity exhibits a second predetermined value is 0.04 to 0.31 ?m; and the total amount of the nickel contained in the iron-nickel diffusion layer and the nickel contained in the nickel layer is 4.4 g/m2 or more and less than 10.8 g/m2.

  • Patent number: 8097357
    Abstract: A battery can of the present invention ensures a stable and favorable contact with an electrode and thus makes it possible to obtain a highly reliable battery excellent in high rate discharge characteristics. The battery can having an opening, including a cylindrical side portion and a bottom portion, of the present invention is formed from a steel plate. The steel plate has an Ni—Fe alloy layer on the inner face side of the battery can. The Ni—Fe alloy layer has an oxide layer containing iron and having a thickness of 10 to 50 nm on the inner face side of the battery can.

  • Patent number: 5409485
    Abstract: In an electrosurgical power supply apparatus combined with an electronic endoscope system, there is provided an electrosurgical signal generator. The electrosurgical signal generator includes PROM for previously storing data representative of electrosurgical high-frequency currents. In response to a selection signal of an electrosurgical operation mode, the data is read out from PROM to produce the electrosurgical high-frequency current corresponding to the selected electrosurgical operation mode.

  • Patent number: 4576515
    Abstract: A pipe laying apparatus having an excavator for performing excavation in the earth to form a substantially horizontally extending hole, with the excavator having connected to its trailing end a leading end of at least one underground pipe at least partially located in the horizontally extending hole, an injector for injecting a viscosity imparting liquid into the earth in which excavation is being performed by the excavator to produce viscosity imparting liquid containing soil particles. A propelling device positioned against a trailing end of the pipe and is located in a starting pit. The viscosity imparting liquid containing soil particles produced by the excavator and injector are conveyed rearwardly of the excavator past an outer periphery thereof and filled in an annular gap defined between the horizontally extending hole and the pipe while the excavator and pipe are advanced by the propelling device.

  • Patent number: 4167289
    Abstract: In a tunnel boring or shield machine, a method and system for controlling the earth pressure, in which the earth pressure in the chamber of the shield machine body is detected and the detected earth pressure is compared with a reference value to thereby produce a chamber earth pressure deviation signal. In response to the chamber earth pressure deviation signal, means for controlling the amount of conveying earth accumulated in the chamber to the exterior of the machine body and/or means for advancing the shield machine body into the working face are controlled so as to maintain the earth pressure in the chamber within a predetermined range so that the breakdown of the exposed face or earth stratum as well as the rising of the ground are prevented from occurring.In another method and system, the earth pressure at the working face is detected and the detected value is compared with a reference value to produce a signal representing the earth pressure deviation at the working face.
