Patent number: 9640307Abstract: A transformer in which the high-voltage and low-voltage coils are easily laminated when they are alternately laminated in their axial directions, improving power efficiency. The transformer includes: a high-voltage coil including a wire wound around a cylindrical winding drum of a bobbin which is provided with flanges on both ends of the winding drum; a low-voltage coil formed of a flat plate member having an open ring shape, the low-voltage and high-voltage coils being alternately laminated in their axial directions; and a cover member which has a ring plate shape and is coaxially laminated on an outside of a laminate in an axial direction. The low-voltage coil is between the high-voltage coil and the cover member, and a wall portion protruding in the axial direction from the bobbin of the high-voltage coil and a wall portion protruding in the axial direction of the cover member are alternately disposed.Type: GrantFiled: October 29, 2013Date of Patent: May 2, 2017Assignee: FDK CORPORATIONInventors: Masami Miyamoto, Yutaka Ikeda, Akihiro Fujii

Patent number: 6617949Abstract: A choke coil has small difference of wire wound resistances between coils to obtain sufficient unbalance attenuation amount, superior in workability in winding and reduced leakage inductance and line capacity. The choke coil includes first and second coils divided into first and second segments wound on a single spool disposing intermediate insulations layers between respectively adjacent coil segments. The coil segments of the first and second coils are wound alternately. The first coil segment of the first coil and the second coil segment of the second coil being wound in a first winding number and the second coil segment of the second coil and the first coil segment of the second coil being wound in a second winding number. The second winding number being greater than the first winding number for reducing difference of winding resistance between the first and second coils less than or equal to 4%.Type: GrantFiled: September 5, 2002Date of Patent: September 9, 2003Assignee: FDK CorporationInventors: Atsushi Ishizuka, Masami Miyamoto, Masami Nonaka, Tadashi Sato

Patent number: 6262651Abstract: A coil device includes a coil body with a wiring coil wound therearound. The coil body is composed of an insulative core cover with a core received therein. An insulative base is provided with terminals, which the coil body is to be mounted thereon. The core cover includes a planar support portion to be attached to the base, and one of the support portion and the base has, at areas in the vicinity of opposite end portions thereof, engagement grooves, and the other has, at areas in the vicinity of opposite ends thereof, ridges engageable with the engagement grooves. Thus, the support portion can be engaged with the base through a combination of the engagement grooves and the ridges.Type: GrantFiled: September 30, 1999Date of Patent: July 17, 2001Assignee: FDK CorporationInventors: Masami Miyamoto, Yoshiyuki Suzuki, Yoshihiro Mochizuki, Tetsuya Suzuki
