  • Patent number: 11015322
    Abstract: A control device for a hydraulic machine such as a revolving excavator work machine having a structure that can cope with such an engine output decreasing environment as a work under a low atmospheric pressure at a high altitude without generating noise caused by engine rotation number increase. The control device corrects a control output value to be applied to an electromagnetic proportional valve for load-sensing valve control in a load-sensing type pump control system, based on a detected state quantity related to the engine output decreasing environment. When an engine speed-sensitive pump control system is adopted, a control output value generated based on a detected decrease in the actual engine rotation number is combined with a control output value generated by the load-sensing type pump control system.

  • Publication number: 20210152498
    Abstract: An information management apparatus starts a conversation with a chatbot on an information processing terminal in response to a received chat start instruction, and based on the content of the conversation, sends recommend information related to a service to the information processing terminal. The information management apparatus sends pass information that enables access to user information received from the information processing terminal, the pass information being sent to an information processing device that corresponds to a provider of the service, when information indicating a desire to use the service is received from the information processing terminal in response to the recommend information. The information management apparatus deletes the user information when receiving from the information processing device, acknowledgment indicating that the service can be provided to the user that corresponds to the user information accessed using the pass information.
