An engine system includes: a reformer including a catalyst for decomposing fuel into hydrogen and configured to reform the fuel to generate a reformed gas containing the hydrogen; a temperature detection unit configured to detect a temperature of the reformed gas; a rotation fluctuation detection unit configured to detect an amount of rotation fluctuation of an engine; and a deterioration detection unit configured to detect whether reforming performance of the catalyst of the reformer is deteriorated based on detection values of the temperature detection unit and the rotation fluctuation detection unit, wherein when, in an idling period of the engine, the amount of rotation fluctuation of the engine is equal to or greater than a second threshold in a state where the temperature of the reformed gas is equal to or higher than a first threshold, the deterioration detection unit determines that the reforming performance of the catalyst is deteriorated.

Engine system

A combustor includes: a housing having an annular shape of which one end side is open and of which the other end side is closed; at least one introduction portion that introduces a fuel and an oxidizing gas into the housing to generate a tubular flow; and an ignition unit that ignites the fuel introduced into the housing. The ignition unit includes a discharge electrode and a ground electrode. A space that the fuel and the oxidizing gas reach is provided between the discharge electrode and the ground electrode.

Combustor

An engine system includes: a combustor including an ignition unit configured to ignite the fuel gas and configured to generate combustion gas that heats a catalyst; an outside air temperature detection unit configured to detect an outside air temperature; a catalyst temperature detection unit configured to detect a temperature of the catalyst; an operating environment detection unit configured to detect an operating environment of the combustor; a combustion time determination unit configured to determine combustion time of the combustor; and a start control unit configured to, at a time of starting the engine, perform ON control on a starter and the ignition unit and control a third fuel supply valve, a first flow rate control valve, and a second flow rate control valve to open, and thereafter when the combustion time elapses, perform OFF control on the ignition unit and control the third fuel supply valve to close.

Provided is a chemical heat storage apparatus that includes a reactor that exchanges heat with a heating object and includes a reaction material generating heat via chemical reaction with a reaction medium, the reaction medium being desorbed from the reaction material when heat is given, a reservoir storing the reaction medium, a reaction medium flow system allowing the reaction medium to flow between the reactor and the reservoir, a heat generation control unit controlling the reaction medium flow system, and an exhaust gas utilization unit desorbing the reaction medium from the reaction material via heat of exhaust gas discharged from an internal combustion engine and heating the heating object via the heat of the exhaust gas when a temperature of the exhaust gas reaches a predetermined temperature or more.

Chemical heat storage apparatus

An anodeof an electrochemical deviceis connected to the cathode of a battery, and a cathodeof the electrochemical deviceis connected to the anode of the battery. An electrolyte layercontaining electrolytes is arranged between the anodeand the cathode. Electrolyte layeris formed by alternately laminating two types of electrolytes formed in the shape of plates. A first electrolyte is a proton conductor, and a second electrolyte is an oxygen ion conductor. A purification apparatusincludes a plurality of electrochemical devices

Electrochemical device and exhaust gas purification apparatus

An organic EL element that is an electroluminescence element has at least an organic layer held between a pair of electrodes. At least an electrode made of material having a higher volume resistivity, of the pair of electrodes, is formed in a flat form. The organic layer is provided with a plurality of non-light emitting portions. The non-light emitting portions are provided so that a larger number of non-light emitting portions exist per unit area at a position physically closer to the position of a terminal portion at which the electrode made of material having the higher volume resistivity is connected to an external connection terminal. As a result, the level of current passing per unit area is substantially uniform at each position on the element.

Electric field light emitting element

A transparent substrate on which a transparent electrode layer is formed is prepared. An insulating layer having a first pattern for exposing a light-emitting region and a first terminal portion and covering a second terminal portion is formed on the transparent electrode layer. Then, an organic layer is formed on the entire surface of the transparent electrode layer and the insulating layer. A reflection electrode layer having a second pattern for covering the light-emitting region and the second terminal portion and exposing the first terminal portion is formed on the organic layer. After that, an exposed portion of the organic layer is removed by dry etching to expose a region of the first electrode layer in the first terminal portion. Finally, a sealing film having a third pattern for covering the light-emitting region and exposing the first terminal portion and the second terminal portion is formed on the resultant transparent substrate, thereby exposing the first terminal portion and the second terminal portion.

Organic EL device manufacturing method and organic EL device

An electroluminescence element includes a first electrode, a second electrode, and a light emission layer arranged between the first electrode and the second electrode. The first electrode is formed of a material having a higher volume resistivity than that of the material of the second electrode. A connector portion electrically connects a feeder portion to the first electrode. The resistance value of the connector portion differs in correspondence with a position at which the connector portion connects the feeder portion to the first electrode. The brightness distribution of the electroluminescence element is thus adjusted to a desired state.
