摘要:
A fluid flow rate control method is provided that uses a flow rate range variable type pressure type flow rate control device provided with at least two or more parallel fluid passages disposed between the downstream side of a control valve of the control device and a fluid supply pipe passage, and orifices having different fluid flow rate characteristics are respectively interposed in parallel fluid passages to pass fluid in a first flow rate region through one orifice for flow rate control, and to pass fluid in a second flow rate region through at least another orifice for flow rate control. Flow rate characteristics of the respective orifices are selected so that a maximum controllable flow rate of fluid in the first flow rate region at low flow rate is smaller than 10% of a maximum controllable flow rate in the second flow rate region at high flow rate.

A data management apparatus for a data management system including first and second networks interposed by a communication control apparatus includes a reception unit receiving response request data pertaining to an electronic device from an external apparatus and response result data from the communication control apparatus, a transmission unit transmitting the response request data to the communication control apparatus, and a management unit managing a series of response status history data during a period between receiving of the response request data and receiving of the response result data responsive to the response request data based on the response request data and the response result data. The data management apparatus being connected to the first network and managing history data of the response request data. One or more service management apparatuses being connected to the second network and managing a response service corresponding to the response request data.
摘要:
An equipment management system includes an equipment managing apparatus and at least one electronic equipment coupled via a data channel. The equipment managing apparatus holds updating data in a holding part, judges whether the holding part holds the updating data, and sends the updating data to the electronic equipment. The electronic equipment receives the updating data from the equipment managing apparatus, judges whether a software update of the application software is executable, and requests the software update with respect to the application software.
