A winding component includes a core that surrounds an outer circumference of a coil and end surfaces of flanges to form a closed magnetic circuit, in which notches through which end portions of the coil are drawn outward are so formed in the flanges that each of the notches extends radially inward from an outer circumferential edge of the corresponding flange, a wall that surrounds each of the notches such that the wall stands axially outward on the flange, a thick portion in a winding part in correspondence with the notches and thicker than other portions of the winding part, and a lid formed of a sidewall between an outer circumferential surface of the wall and the core and covers the outer circumferential surface of the wall and a top plate at an axially outer end of the sidewall and covers an opening in the wall.

Winding component

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.

Transformer

Provided are a manufacturing method of a semiconductor device and a substrate processing apparatus. The manufacturing method of the semiconductor device includes: loading a plurality of substrates into a reaction vessel, which is configured by a process tube and a manifold that supports the process tube, and arranging the loaded substrates within the reaction vessel; pre-processing the plurality of substrates by supplying a pre-process gas from the manifold side toward the process tube side within the reaction vessel; main-processing the plurality of pre-processed substrates by supplying a main-process gas from the manifold side toward the process tube side within the reaction vessel; and unloading the plurality of main-processed substrates from the reaction vessel, wherein in pre-processing the plurality of substrates, the pre-process gas is supplied from at least one position in an area corresponding to the manifold, and at least one position in an upper area of an area corresponding to a substrate arrangement area.

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%.

Choke coil

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.
