Abstract: A verification apparatus acquires a source code for multiparty computation, while changing a combination of options settable to a multiparty computation compiler, compiles the source code for each combination of options to generate a plurality of multiparty computation executable codes, selects at least one multiparty computation executable code from the plurality of multiparty computation executable codes as a verification code and provides the at least one verification code to a verification environment of multiparty computation, generates an evaluation index with respect to an execution result of at least one verification code in the verification environment, and selects at least one recommended code from the plurality of multiparty computation executable codes, based on the evaluation index corresponding to at least one verification code and outputs the selected recommended code.

Abstract: Provided is a powder (A) for a magnetic core for producing a powder magnetic core, the powder (A) for a magnetic core including: as a main component a granulated powder (1) obtained by granulating iron-based amorphous powder having been subjected to insulation treatment and having a particle size distribution falling within a range of from 1 ?m to 200 ?m; and glass powder having a softening point lower than a temperature of the annealing treatment. The granulated powder (1) is obtained by binding particles (2) of magnetic powder each formed of a particle (3) of the iron-based amorphous powder and an insulating coating (4) configured to coat the surface of the particle (3) to each other through use of a PVA aqueous solution having a viscosity of from 3 mPa·s to 25 mPa·s.

Abstract: Provided is a powder for a magnetic core (1), including a soft magnetic metal powder (2); and an insulating coating film (3) covering a surface of the soft magnetic metal powder (2), in which the insulating coating film (3) is formed of an aggregate of crystals (4) obtained by cleaving a layered oxide. The crystals (4) are obtained by, for example, cleaving a swellable smectite-group mineral, which is one kind of swellable layered clay mineral as the layered oxide.

Abstract: Provided is a powder (1) for a magnetic core, including: a soft magnetic metal powder (2); an insulating coating (3) for covering a surface of the soft magnetic metal powder (2); and a lubricating coating (4) for covering a surface of the insulating coating (3). The lubricating coating (4) is formed by eliminating a solvent component and causing a lubricating component to adhere to a coated powder (1?) in a lubricant solution (26) supplied into a container (21) in which the coated powder (1?) is being stirred in a floating state, the coated powder being formed by covering the surface of the soft magnetic metal powder (2) with the insulating coating (3).

Abstract: An eddy current loss at a frequency of 3,000 Hz is set to less than 150 W/kg by setting a single particle diameter-equivalent diameter dS of soft magnetic metal powder represented by the following formula to 210 ?m or less. In the formula, dS represents a single particle diameter-equivalent diameter of the soft magnetic metal powder [m], dMN represents a number average particle diameter of the soft magnetic metal powder [m], and ? represents a standard deviation of the particle diameter of the soft magnetic metal powder [m].

Abstract: A sintered gear serving as a mechanical structure component is a mechanical structure component made of a metal sintered body, and includes a base region; and a high density region formed so as to include a maximum stress position at which a maximum tensile stress or a maximum shear stress is applied, and to include a surface, in which the high density region is lower in porosity than the base region. A surface hardened layer is formed in a region including the surface by performing a hardening process.
