摘要:
An adhesion preventing member 21 formed in a substantially circular-cylindrical shape is provided in an exhaust pipe 2. Urea water injected from an injection nozzle 6 is introduced into an inner peripheral side of the adhesion preventing member 21 through an opening portion 21a, and hence adhesion of the urea water to an inner peripheral surface 2a of the exhaust pipe 2 is inhibited. In the adhesion preventing member 21, there are provided five dispersion members 22 each having a plurality of through-holes 22a and urea water is dispersed in the exhaust pipe 2 by flowing through through-holes 22a. The adhesion preventing member 21 and the dispersion members 22 are arranged at a part spaced apart from the inner peripheral surface 2a of the exhaust pipe 2, that is, at a part which is heated to high temperature in the exhaust pipe 2.
摘要:
An EL device including an anode, an organic light emitting layer, and a cathode is formed on a glass substrate, and a sealing film made of Si and SiN x in which a ratio of the number of silicon atoms bonded to silicon atoms to the number of silicon atoms bonded to nitrogen atoms is equal to or larger than 0.6 but is equal to or smaller than 2.0 is formed on a surface of the EL element so as to cover the EL element.
摘要:
An exhaust gas treatment system for an internal combustion engine includes an exhaust pipe (6) and an energy applying device (12). Exhaust gas discharged from the internal combustion engine flows into the exhaust pipe (6). The energy applying device (12) applies energy to the exhaust gas flowing through the exhaust pipe. The energy applied to the exhaust gas is greater than the energy for decomposing nitrogen monoxide (NO) and less than the energy for decomposing nitrogen (N 2 ).
摘要:
Formed on a glass substrate (1) is an EL element (2) including an anode (3), an organic light emitting layer (4), and a cathode (5). A first protective film (6) is formed on a surface of the EL element (2) to cover the EL element (2) through a dry process. A second protective film (7) is then formed on a surface of the first protective film to cover the first protective film by using polysilazane through a wet process. Even if an uncovered portion is left in the first protective film owing to the existence of a foreign matter thereon, the second protective film covers the uncovered portion to avoid intrusion of oxygen or other gases, moisture, etc. into the EL element from the outside.
摘要:
A method is provided for separating gas including diamagnetic materials and paramagnetic materials containing nitrogen oxides and oxygen into diamagnetic materials, nitrogen oxides, and oxygen. The method includes steps of providing a magnetic device (11) along a gas passage (6), and providing a plurality of flow passages (9a-9f). Each flow passage (9a-9f) has one end that is separately connected to the gas passage (6). The flow passages (9a-9f) extend in a direction that a force due to a magnetic field of the magnetic device (11) is applied to the paramagnetic materials in the gas. The method further includes a step of allowing the gas to flow into the flow passages (9a-9f) so that nitrogen oxides and oxygen in the gas enter into a corresponding flow passage (9a-9f) among the plurality of the flow passages.
