  • Patent number: 10066532
    Abstract: An object is to improve fuel consumption, drivability and exhaust gas purification by efficiently converting waste heat of the engine into electrical power and storing the electrical power in a dedicated electric storage so that the boost pressure from the electric air compressor can be flexibly outputted. The electric supercharging device includes a steam cycle device configured to expand the steam generated by waste heat of an engine to rotate an expander, a first generator connected to the expander and configured to generate an electrical power by torque of the expander, a dedicated battery which stores the electrical power generated by the first generator, and an electric supercharger configured to drive a compressor with a motor driven by the electrical power of the dedicated battery to generate compressed air.

  • Patent number: 6710479
    Abstract: Cooling oil passes through a cooling oil passage (28) on the inside of an iron core (7), and cools the inside of the iron core (7). Further, cooling air passes through a cooling air passage (31) in the inside of the iron core (7) and a clearance (5) between the internal periphery of the iron core (7) and the external periphery of a rotor (4), and cools the inside of the iron core (7) and the rotor (4). Therefore, it is possible to effectively cool the internal periphery side of a stator (6) and the rotor (4). When a cooling oil is sprayed from the cooling oil passage (28) into the cooling air passage (31), it is possible to obtain a more effective cooling effect by utilizing the latent heat of vaporization of the mist of the cooling oil.

  • Patent number: 6161528
    Abstract: A recirculating exhaust gas cooling device is provided for cooling exhaust gas of a vehicle engine while the exhaust gas is recirculating through an EGR system designed to lower NOx emission levels. The cooling device includes a housing in which an exhaust gas recirculation passage and a cooling fluid passages are located next to each other, to extend in parallel with each other, and a heat-exchange core member rotatably provided in the housing and defining a multiplicity of passages that extend in substantially parallel with a rotational axis of the core member, and a rotating mechanism that rotates the core member. The multiple passages of the core member communicate with both of the exhaust gas recirculation passage and the cooling fluid passage. With the core member being rotated, EGR gas passing through the exhaust gas recirculation passage is cooled by a part of the passages of the core member that has been cooled by a cooling fluid passing through the cooling fluid passage.

  • Patent number: 5058516
    Abstract: An apparatus for automatically positioning welt portions and garter lines of pantyhose materials by aligning upper and lower positions in relation to each other for carrying out a pantyhose panty part seaming process, in which when detection sensors detect materials roughly fitted to respective upper and lower template assemblies, plates for positioning garter lines cause a panty part to move backward to be inserted deeply onto the template assemblies and the garter lines of the upper and lower materials are positioned by aligning with each other through detection sensors for positioning garter lines, and successively, a plate for positioning welt portions causes the panty part to move backward, stretching the panty part to a prescribed length so that the welt portions of the upper and lower materials are aligned with each other, thus fully fitting the upper and lower materials to the template assemblies and, at the same time completing the positioning of the welt portions and garter lines by aligning upper a

  • Patent number: 4881959
    Abstract: An exhaust emission purifier for a diesel engine has a particulate trap disposed in the exhaust emission passage of the diesel engine for entrapping particulates contained in exhaust gases emitted from the diesel engine, the particulate trap being housed in a canning container. An electric heater is disposed in the canning container upstream of the particulate trap for heating the exhaust gases to a temperature which is high enough to burn particulates entrapped by the particulate trap. A heat conductor/converter device disposed in the canning container upstream of the electric heater for absorbing heat radiated from the electric heater and discharging the absorbed heat into air flowing from a position upstream of the canning container into the particulate trap. The heat generated by the electric heater is efficiently utilized to heat the air introduced into the particulate trap for reliably and quickly igniting and burning the entrapped particulates.
