  • Patent number: 10494985
    Abstract: A warm-up device is provided in a cooling-water circuit, through which cooling water is circulated so as to pass through an engine. The warm-up device has a heat accumulating passage, in which a heat accumulating device is provided, and an accumulating-device bypassing passage bypassing the heat accumulating device. A waste-heat collecting device is provided in the cooling-water circuit so that heat is collected from exhaust gas from the engine and such collected heat is accumulated in the heat accumulating device. The cooling water is circulated through the heat accumulating device during a start-up operation of the engine in order to heat the cooling water flowing into the engine so as to quickly warm up the engine.

  • Publication number: 20190272952
    Abstract: A magnetic core includes a winding core and first and second flanges connected to the winding core. First and second terminal electrodes are connected to a lead frame. The first flange is bonded to the first and second terminal electrodes. Third and fourth terminal electrodes are bonded to the second flange. First and second insulation-coated conductive wires are wound about the winding core. The first and second insulation-coated conductive wires are connected to the first and second terminal electrodes and the third and fourth terminal electrodes. The lead frame is bent so as to rotate the magnetic core by 90 degrees with respect to the lead frame. A magnetic plate is bonded to the magnetic core. The magnetic core is removed from the lead frame by removing the first and second terminal electrodes from the lead frame, thereby providing a common-mode choke coil. The common-mode choke coil having stable electrical performance is produced efficiently by the above method.

  • Patent number: 10378424
    Abstract: The exhaust gas recirculation system comprises an exhaust recirculation pipe configured to recirculate an exhaust gas from an engine into an intake pipe of the engine, an exhaust gas heat exchanger connected to the exhaust recirculation pipe and configured to perform an heat exchange between the exhaust gas and an engine cooling water used for cooling the engine, a cooling water pipe configured to circulate the engine cooling water to the exhaust gas heat exchanger, and a heat insulating member forming a heat insulating layer on a heat transfer path from the exhaust gas heat exchanger to the outside.

  • Patent number: 8305695
    Abstract: The present invention is directed to high magnification compact zoom lenses that are reduced in diameter of groups of lens pieces closer to the imaging plane to provide downsized lightweight zoom lenses of magnification as high as 20 diameters, with an image stabilizer or vibration compensating mechanism being also reduced in dimensions. An exemplary improved high magnification zoom lens has four groups of lens pieces, namely, the first or leading lens group G1 of positive refractivity in the foremost position closer to the subject, the second lens group G2 of negative refractivity, the third lens group G3 of positive refractivity, and the fourth lens group G4 of positive refractivity in the rearmost position closer to the imaging plane, all arranged in this order.
