The present invention has an object of providing a reactor including cores with higher heat dissipation and a coil with less eddy-current loss. A reactor according to the present invention includes: a plurality of divided cores having a shape obtained by dividing an annular core in a circumferential direction, the divided cores being made of a soft magnetic material; a core gap part disposed between the divided cores in the annular core formed by combining the plurality of divided cores, the core gap part being made of a non-magnetic material; annular heat-dissipating cases that house the divided cores and the core gap part; and a coil wound around the heat-dissipating cases, wherein the heat-dissipating cases are made of a material whose thermal conductivity is as high as 100 W/(m·K) or more.

Reactor

The present disclosure relates to an imaging system and a control method that make it possible to implement setting for an external flash by an operation on a camera side. Setting coordination processing is executed in which setting information of an external flash () is transmitted and received between a first communication unit (A) and a second communication unit (). Further, a second display unit is caused to display a setting screen to be used for setting a setting item of the external flash, and the setting information changed by an operation on the second operation unit is caused to be transmitted from the imaging device () to the external flash () via the first communication unit (A) and the second communication unit (), and a setting for the external flash () is caused to be applied.

Imaging system and control method

The invention provides an organic EL device including a pair of electrodes and at least one luminescent layer between the pair of electrodes, the at least one luminescent layer including at least two phosphorescent materials, an electrically inert material, and a charge-transporting material, the at least two phosphorescent materials being selected from a blue phosphorescent material having a luminescence peak in a range of from 420 nm to less than 500 nm, a green phosphorescent material having a luminescence peak in a range of from 500 nm to less than 570 nm, or a red phosphorescent material having a luminescence peak in a range of from 570 nm to 650 nm. The invention also provides a luminescence apparatus including the above organic EL device.
