Abstract: A CPAP machine includes a housing, an air pipe, a blower, and a sensor S. The housing includes a first opening and a second opening. The air pipe is disposed in the housing, and has an inlet port continuous with the first opening, and an outlet port. The sensor S measures a temperature or a humidity of a gas that flows through an internal space of the air pipe. The air pipe includes a box that protrudes outward from a wall of the air pipe and a wall disposed in the box. The wall is disposed in the box to define a space continuous with the internal space of the air pipe, a space, and a space that connects the space and the space to each other. The sensor S is disposed at a wall of the box.

Abstract: An inductor includes an annular core, and a first coil and a second coil which are wound around the core. The core has an internal surface, an external surface, a first end surface, and a second end surface. The first coil and the second coil include a first coil piece having a length of one turn and a second coil piece having a length of one turn. The first coil piece and the second coil piece surround the internal surface, the first end surface, the external surface, and the second end surface of the core. The first coil piece has, at its tip, a joint portion to be joined to the second coil piece, and the second coil piece has, at its tip, a joint surface to be in contact with the joint portion. Thus, the resistance value of the coil is reduced.

Abstract: An inductor component includes a core having an annular shape; an insulating member that covers a portion of the core; a coil wound around the core and the insulating member; and a buffer member that is elastic. The core has a first face, a second face that crosses the first face, and a third face that faces the second face and crosses the first face. The insulating member is provided to cover the first face, a portion of the second face, and a portion of the third face. The core and the insulating member are bonded to each other with the buffer member interposed therebetween.

Abstract: A common mode choke coil includes a core, and first and second coils opposed to each other and wound on the core. The core can have a square shape, or an elongated shape having a long axis and a short axis when viewed in a direction along a central axis of the core. Each of the first and second coils is a single-layer coil. An area of a cross-section of the core taken perpendicular to a circumferential direction of the core is constant in the circumferential direction of the core. The cross-section of the core has a quadrilateral shape.

Abstract: An inductor component includes a case; an annular core accommodated in the case; a coil wound around the core; and an electrode terminal attached to the case and connected to the coil. The electrode terminal includes a mounting surface portion that is disposed along an end surface of the core and that is to be mounted on a mount substrate, and a connection surface portion that is perpendicularly connected to the mounting surface portion and that is disposed along an outer peripheral surface of the core. The coil includes a plurality of pin members including a first linear pin member. A connection surface that is a part of an outer peripheral surface of the first linear pin member is in surface-contact with a first main surface of the connection surface portion in a state in which the connection surface is positioned parallel to the first main surface.
