  • Publication number: 20200017746
    Abstract: A base fluid for heat medium contains a hydrophilic ionic liquid and water. A molecular weight of the hydrophilic ionic liquid is at or below 150. The hydrophilic ionic liquid is methylammonium nitrate. Since the ionic liquid has favorable thermal stability, the thermal stability of the base fluid for heat medium can be secured. Since the molecular weight of the hydrophilic ionic liquid is at or below 150, the base fluid for heat medium has a low kinematic viscosity. Further, since the freezing point depression effect can be obtained by dissolving the ionic liquid in water, a low freezing point can be realized.

  • Patent number: 9754710
    Abstract: The compact for a magnetic core is manufactured by filling a soft magnetic powder in the die hole, pressing it to form a compact at a density ratio of the soft magnetic powder being 91% or more, and extruding it from the die hole. Before filling the soft magnetic powder to the die hole, a lubricating coating containing lubricating oil and molybdenum disulfide particles is formed on the inner surface of the die hole. It is more effective when further containing insulating ceramic particles. On the extrusion-sliding surface, the compact has a surface layer of the structure that molybdenum disulfide particles and the insulating ceramic particles are interposed between the soft magnetic powder particles, and insulation of soft magnetic powder particles in the surface layer is not destroyed by extrusion. This provides a powder magnetic core suitable for high frequency application.
