Abstract: A sensory control method includes a step of receiving, a step of converting, and a step of outputting. In the step of receiving, a sensitivity parameter is received. In the step of converting, the received sensitivity parameter is converted into, among a plurality of physical parameters included in physical properties relating to a sensory presentation, a physical parameter correlated with the sensitivity parameter. In the step of outputting, a sensory presentation signal based on the physical parameter obtained as a result of the conversion is output.

Abstract: In a magnetic core including a core assembly having a structure that multiple thin strip blocks are arranged, the thin strip blocks being formed of multiple laminates of nanocrystalline thin strips made of a nanocrystal-containing alloy material, the thin strip block includes a fixedly joined portion in which the nanocrystalline thin strips adjacent to each other in a lamination direction are fixedly joined together. The fixedly joined portion may include side surfaces of the nanocrystalline thin strips and may be a laser welded portion.

Abstract: In a magnetic core including a core assembly formed of multiple arranged thin strip blocks, each of the thin strip blocks has a structure that multiple nanocrystalline thin strips having a bcc-Fe phase as a main phase are laminated one above another, and an iron loss in the nanocrystalline thin strip positioned at a center of the thin strip block in a thickness direction thereof is lower than an iron loss in the nanocrystalline thin strip positioned in a surface layer of the thin strip block. The nanocrystalline thin strip may be a heat-treated product of an amorphous thin strip made of an amorphous alloy material, and the thin strip block may include a fixedly joined portion in which the nanocrystalline thin strips adjacent to each other in a lamination direction are fixedly joined together.

Abstract: In a magnetic core including a laminated core in which multiple core thin strips are laminated, the magnetic core includes a cutting mark region formed by cutting tie sticks 212, connected to the core thin strips 511, in a lamination direction of the core thin strips 511, and the cutting mark region 51C is positioned on an inner side than outer peripheries of the core thin strips 511. The core thin strip 511 may include a portion made of a nanocrystal-containing alloy material that is obtained by nano-crystallizing an amorphous alloy material with heat treatment.
