  • Patent number: 12037935
    Abstract: A cooling apparatus for a vehicle includes air-cooling first and second heat exchangers that are placed beside each other. A coolant flow-out portion of the first heat exchanger from which a first coolant which is a cooling target of the first heat exchanger flows out and a coolant flow-out portion of the second heat exchanger from which a second coolant which is a cooling target of the second heat exchanger flows out are placed at ends at opposite positions separated along a diagonal line on a parallel placement surface of the two heat exchangers. A first cooling fan is placed opposing the coolant flow-out portion of the first heat exchanger, and a second cooling fan is placed opposing the coolant flow-out portion of the second heat exchanger. With this configuration, cooling performance of two air-cooling heat exchangers placed beside each other can be improved.

  • Patent number: 9896873
    Abstract: A tension applying apparatus includes a tension applying member applying a tensile force to a drive cable by being pressed against the drive cable, a biasing member generating a biasing force for pressing the tension applying member against the drive cable, a holding member including a guide portion which restricts a moving direction of the tension applying member and a housing member housing the tension applying member and the holding member. The holding member is configured to change the moving direction of the tension applying member which is guided by the guide portion in a state where the holding member including a rotation shaft is housed within the housing member. The housing member includes a holding structure holding the holding member at a position to which the holding member rotates in a direction where a pressing angle of the tension applying member relative to the drive cable becomes shallow.

  • Patent number: 9373441
    Abstract: A composite electronic component with a built-in coil is provided which can be produced inexpensively, which can effectively increase insulating reliability, and which has the antistatic function. Coil wirings are disposed inside a sintered body that is formed by stacking a plurality of ferrite layers, which are fired as an integral unit. Voltage nonlinear members are incorporated in the sintered body at a different height position from those of the coil wirings. First inner electrodes and second inner electrodes are disposed in opposing relation with the voltage nonlinear members interposed therebetween. A magnetic circuit forming portion is constituted by a part of the ferrite layers and the coil wirings in a portion in which the coil wirings are arranged, and an antistatic portion is constituted in a portion in which the remaining ferrite layers, the voltage nonlinear members, and the first and second inner electrodes are arranged.
