Abstract: Provided is a battery armoring stainless steel foil which, without the need for a special treatment such as corona discharge, has excellent adhesiveness to resin after being thermally shocked and after being immersed in an electrolyte solution. A battery armoring stainless steel foil (1) includes an oxide film (1a), having a thickness of not less than 2 nm, which contains (i) one or more metallic elements, existing as a hydroxide, in an amount of not less than 35 mol percent and (ii) SiO2 in an amount of not more than 40 mol percent, the battery armoring stainless steel foil (1) having an arithmetic mean roughness Ra of less than 0.1 ?m but not less than 0.02 ?m in a direction orthogonal to a direction in which the battery armoring stainless steel foil (1) has been rolled.

Abstract: The purpose of the present invention is to provide a method for recovering calcium-containing solid components from steelmaking slag, with which it is possible to easily increase the calcium recovery rate. With the method, steelmaking slag is immersed in an aqueous solution containing carbon dioxide, and calcium in the steelmaking slag is made to leach out into the aqueous solution. Next, the immersed steelmaking slag is removed from the aqueous solution, and, subsequently, the pH of the aqueous solution is increased. When solid components precipitated by doing so are recovered, it is possible to recover solid components containing 20% or more by mass in terms of calcium atoms.

Abstract: An aqueous solution containing 30 ppm or more of carbon dioxide is brought into contact with a steel-making slag to elute phosphorus and calcium contained in the steel-making slag into the aqueous solution. Subsequently, carbon dioxide is removed from the aqueous solution to precipitate a mixture comprising a phosphorus compound and a calcium compound. In this manner, a mixture comprising a phosphorus compound and a calcium compound and containing phosphorus in an amount of 1% by mass or more in terms of phosphorus atom content can be produced.

Abstract: An interface apparatus comprises a plurality of contact pins, an upper housing, a lower housing, a plurality of conductive members and a resilient supporter. The upper housing holds the contact pins with their upper end portions upwardly projecting from the upper housing, respectively. The resilient supporter is held by the lower housing and movably supports the upper housing. Upon a test of an IC package, package terminals of the IC package are brought into contact with the upper end portions of the contact pins generally by the resilient supporter; its spring force is independent from the sizes of the package terminals, resulting reliable contacts between the contact pins and the package terminals even if the package terminals become smaller.

Abstract: A semiconductor device is provided with a memory cell array, an interface circuit portion and a control circuit. The interface circuit portion controls input and output of a signal between the memory array and an external circuit. The control circuit controls operating states of the interface circuit portion independently of the memory cell array based on an externally inputted signal.

Abstract: The object of the present invention is to improve working efficiency in system construction works. This is accomplished when a customer 1 makes a request for system construction to a provider of the infrastructure construction service 2, and the service provider 2 conducts a consultation. The service provider 2 uses the e-editor to create a configuration drawing, then sends data that has been input to the e-editor to a server of the configuration file generation service 3. The server automatically generates a configuration file with macro expansion of a template, and then after customization as needed, sending the configuration file back to the service provider. The service provider installs the configuration file in the customer's system.
