A light-emitting device includes an HTL including a metal chalcogenide between an anode and an EML, with an IL including an organic material at least between the HTL and the EML. A distance between the HTL and the EML in a light-emitting element that emits light in a wavelength band having the shortest light emission peak wavelength is greater than a distance between the HTL and the EML in each of the other light-emitting elements.

Light-emitting device

A light-emitting element is provided with an anode, a light-emitting layer including quantum dots, and a cathode. The light-emitting element includes: an electron transport layer provided between the cathode and the light-emitting layer; and a hole tunneling insulating layer provided between the anode and the light-emitting layer and in contact with the anode and the light-emitting layer.

Light-emitting element and display device

An optical disk () of the present invention includes (i) a medium information region () (a) in which type identification information is recorded by recesses and/or protrusions which are formed by a given modulation method and whose lengths are longer than a length of an optical system resolution limit of a playback device and (b) in which first address information is recorded in a first address data format and (ii) a data region () (a) in which content data is recorded by recesses and/or protrusions which are formed by the given modulation method and which include a recess and/or a protrusion whose length is shorter than the length of the optical system resolution limit and (b) in which second address information is recorded in a second address data format.

Method for playing back information recording medium

Information recording medium and reproduction device

A reproducing device () includes (i) an optical pickup () for irradiating, with reproduction light, an optical disk () which is a super-resolution medium, (ii) an RF signal processing circuit () for converting, into a reproduction signal, light which reflected off optical disk (), (iii) an i-MLSE detecting section () for evaluating quality of the reproduction signal, and (iv) a spherical aberration correcting section () for correcting a spherical aberration by using a result of evaluation of the quality of the reproduction signal.

Reproducing device

A carbon dioxide concentration control device () is provided with a control unit () that controls an absorption amount of carbon dioxide of a carbon dioxide absorbent () per unit hour, and a regeneration control unit () that generates the carbon dioxide absorbent (), and a second drive energy supply unit () which is different from a first drive energy supply unit () that supplies power to the control unit () supplies power to the regeneration control unit (), and thus a carbon dioxide concentration in a space is controlled to be an appropriate value for long periods of time.

Carbon dioxide concentration control device and apparatus

Consumed energy and cost relating to control of a carbon dioxide concentration is reduced. Each of COconcentration control systems (to) includes a measuring unit () that measures a COconcentration, a COabsorption unit () that has a COabsorption material () for absorbing COat a rate depending on the temperature thereof, and a control unit () that controls the temperature of the COabsorption material () by using exhaust heat of a power system (), so as to control a COabsorption rate of the COabsorption material ().

Carbon dioxide concentration control system and carbon dioxide concentration control device

In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (Pmax) or a longest space (Smax) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (Pmax) or a longest space (Smax) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.
