摘要:
An object of the present invention is to separate CO2 gas generated in a cement-manufacturing facility in a high concentration and recover the CO2 gas. The present invention includes: feeding a cement material before calcination and a heat medium which has a particle diameter larger than that of the cement material and has been heated to the calcination temperature or higher in a medium-heating furnace (14), to a mixing calciner (12); and recovering the CO2 gas generated by the calcination of the cement material. The heat medium circulates between the medium-heating furnace and the mixing calciner. Another aspect of the present invention includes: feeding a cement material before calcination to a regenerative calciner (112) which has been heated to the calcination temperature or higher and has stored heat therein; and recovering the CO2 gas generated by the calcination of the cement material.
摘要:
An object of this invention is to provide a mixing calciner that can separate and recover CO2 gas in a high concentration, which is generated when a to-be-calcined cement material is mixed with a superheated calcined portion and calcined, by employing a fluidized-bed type or a spouted-bed type. The invention provides a mixing calciner (12) which mixes the calcined cement material with the superheated calcined portion to cause a calcination reaction, wherein the mixing calciner is the fluidized-bed type or the spouted-bed type, and is provided with a plurality of feed lines (25) for feeding the to-be-calcined cement material. In addition, this invention provides a mixing calciner which easily fluidizes or spouts a cement material even when a heat medium has a particle diameter larger than that of the cement material, and can separate and recover CO2 gas generated in a cement-manufacturing facility in a high concentration.

摘要:
A vehicle drive device configured with reduced axial dimensions, while still having appropriate lubrication. The vehicle drive device is configured with an input shaft coupled to an engine, a rotary electric machine, and an output shaft coupled to wheels. A power transfer mechanism couples input shaft, the rotary electric machine, and the output shaft. A case houses at least the rotary electric machine and the power transfer mechanism. An oil reserving portion capable of reserving oil supplied by rotation of the power transfer mechanism is provided above the rotor shaft inside the case. A communication oil passage is oriented between the oil reserving portion and an inner circumferential space formed inside the rotor shaft. The rotor shaft is disposed to be inserted into the inside housing space, and has a supply communication hole that communicates between the inner circumferential space and the inside housing space.

A power transmission device for a vehicle configured with a rotary power member, and a mechanism configured with a plurality of operational states. A switching shaft changes the operational state of the operating mechanism and is moved by an electric actuator. A control transmission transmits the power from the actuator to the shaft. The housing for the rotary member includes is configured so that the switching shaft projects outwards from the housing. The electric actuator is arranged at a location facing, of a surface of the housing portion of the case, a portion that does not overlap another portion where the switching shaft projects, when viewed in the axial direction of the rotational axis of the rotary member. A part of the actuator is arranged on a case side relative to a vertical line passing through the portion where the switching shaft projects from the housing portion of the case.

A vehicle drive device configured with an input member coupled to an internal combustion engine, a rotary electric machine, an output member coupled to wheels, and a power transfer mechanism that drivably couples the input member, the rotary electric machine, and the output member. An oil collecting portion is configured to collect oil supplied by rotation of the power transfer mechanism, The collected oil falling passage is configured to cause the oil collected by the oil collecting portion to flow downward to be supplied to a portion of a facing wall surface located above a cylindrical member. A communication oil passage communicates between the gap and the inside housing space is formed at a portion of abutment between the subject support bearing and the support projecting portion.

A transmissive phase plate with a function of correcting direction of polarization of light rays in an incident divergent or convergent light flux in addition to functions as a wave plate. Conditions of polarization of incident light rays are corrected by a polarization-correcting optical multi-layer coating which is formed by alternately depositing a high refractivity layer and a low refractivity layer on curved substrative surface of a predetermined radius of curvature. The transmissive phase plate can be applied to correct conditions of polarization of incident light rays of a polarized beam splitter for the purpose of improving contrast ratio of a projection display.

An optical multiplexer/demultiplexer has a plurality of Mach-Zehnder optical interferometer multiplexing/demultiplexing circuits connected in plural stages, at least one of the plurality of Mach-Zehnder optical interferometer multiplexing/demultiplexing circuits including a first optical waveguide, a second optical waveguide disposed along the first optical waveguide, a first directional coupling portion that connects a first part of the first optical waveguide to a first part of the second optical waveguide, and a second directional coupling portion that connects a second part of the first optical waveguide to a second part of the second optical waveguide. A relationship among a coupling portion length LR of at least one of the first and second directional coupling portions, a complete coupling length LC of at least one of the first and second directional coupling portions and a lead portion coupling length Le of at least one of the first and second directional coupling portions, is substantially: π 2 × L e + L R L C = π 4 .
