  • Publication number: 20210328480
    Abstract: A motor oil-cooling structure for cooling, with oil, coils wound around split stator cores of a motor includes injection holes arranged in a circumferential direction of the split stator cores. The motor includes a motor case, a rotor rotatably supported by the motor case, and a stator including the split stator cores fixed to the motor case and arranged along a cylindrical outer periphery of the rotor. Each of the injection holes is structured to inject oil toward a corresponding one of coil gaps each of which is formed between two of the split stator cores adjacent to each other. Furthermore, each of the injection holes is structured to inject oil in a direction inclined by a circumferential inclination angle with respect to a direction of a motor axis, wherein oil injected to the coil gaps in the direction of the motor axis passes straight through the coil gaps.

  • Patent number: 9523397
    Abstract: A breather structure is provided with: a communication passage which communicates a cylinder oil chamber with the atmosphere; and a stem which is disposed in the communication passage. A stem receiving section is formed in the side of the connection passage on the side of the cylinder oil chamber, the stem receiving section allowing the stem to be disposed inside with a clearance which allows air to be discharged from the cylinder oil chamber while maintaining the hydraulic pressure within the cylinder oil chamber. An air discharge section opened to the atmosphere is formed on the side of the atmosphere in the connection passage. Also, a pit section which releases the clearance to the air discharge section and a restricting section which restricts the movement of the stem toward the air discharge section are respectively formed in the inner peripheral surface of the communication passage.

  • Publication number: 20100142541
    Abstract: A media gateway is configured to include a subscriber loop interface circuit, and TDM data-IP packet convert modules #0 and #1 having a redundant configuration and connected to an Internet protocol network via routers. The TDM data-IP packet convert modules #0 and #1 have a function of conducting communication of communication information, a synchronize signal, and IP packet data received from the Internet protocol network, between their active system and standby system. In system changeover, the TDM data-IP packet convert module #0 functioning as the active system transmits the IP packet data received from the Internet protocol network, to the block #1 functioning as the standby system, and both systems execute IP packet data communication synchronously. When IP packet data communication of the standby system is ensured, the standby system and the active system are changed over to vice versa.
