  • Patent number: 11151815
    Abstract: A key information sharing system includes a delivery device that delivers key information as first information for a control device equipped in an object and a user terminal that receives the first information delivered from the delivery device. The delivery device adds second information that allows the first information to be transferred between the user terminal and a third-party terminal without the delivery device, to the first information to be delivered to the user terminal. The user terminal transmits the first information to the third-party terminal in response to an input operation by a user, when the user terminal receives the first information to which the second information has been added.

  • Patent number: 5224845
    Abstract: A refrigerant circulation pump for circulating a liquid refrigerant through an air-conditioner has a small lubrication hole extending through a bearing by means of which a shaft for driving a compressor unit of the pump is rotatably supported. The lubrication hole communicates at one of its opposite ends with a compression chamber of the compressor unit, the other of the opposite ends communicating with a friction point between the shaft and the bearing. While the pump is operating, a part of the liquid refrigerant is fed under pressure from the compression chamber to the friction point between the shaft and the bearing, thereby lubricating the friction point. With this lubrication, the pump is able to operate reliably for a prolonged period of time without causing wear of the shaft and the bearing.
