摘要： A soft magnetic material is a soft magnetic material including a composite magnetic particle (30) having a metal magnetic particle (10) mainly composed of Fe and an insulating coating (20) covering metal magnetic particle (10), and insulating coating (20) contains an iron phosphate compound and an aluminum phosphate compound. The atomic ratio of Fe contained in a contact surface of insulating coating (20) in contact with metal magnetic particle (10) is larger than the atomic ratio of Fe contained in the surface of insulating coating (20). The atomic ratio of Al contained in the contact surface of insulating coating (20) in contact with metal magnetic particle (10) is smaller than the atomic ratio of Al contained in the surface of insulating coating (20). Thus, iron loss can be reduced.

摘要： Disclosed is an Internet FAX apparatus which, after receiving an Internet address from a certain destination, can communicate with the same destination in later transmission or during communication by connecting to a LAN and switching to an Internet FAX mode requiring no communication charge. An Internet facsimile apparatus on the receiving side transmits its Internet facsimile function and Internet address on an NSF signal in a standard protocol of G3 facsimile transmission and/or transmits its telephone number, Internet facsimile function, and Internet address on TSI and NSS signals in the standard protocol of G3 facsimile communication. The Internet facsimile apparatus registers an Internet facsimile function and Internet address of a partner apparatus as destination data. The Internet facsimile apparatus communicates with the partner apparatus by using the Internet address in the destination data in later transmission or by disconnecting ordinary facsimile mode communication and switching to the Internet FAX mode.

摘要： A bonding apparatus including a capillary 40 having a high-frequency coil 50 on its tip end portion and allowing a bonding wire 2 to pass therethrough, a position changing unit for changing the position of the tip of the bonding wire, a gas supply unit for supplying gas into the capillary, and a high-frequency power supply unit for supplying high-frequency power to the high-frequency coil. When the bonding wire is outside a plasma region 52 in the capillary, a microplasma generated in the plasma region is ejected out of the capillary and removes foreign matter or contaminants on the surface of a bonding subject. When the bonding wire is inside the plasma region, the material of the bonding wire is turned into fine particles, and a microplasma 303 containing sputtered fine particles is ejected from the capillary, allowing the material the same as the bonding wire to be deposited on the bonding subject.
