Abstract: In a system, a server establishes a session for verification of drawing information and implements information communication between clients connected to the session. The verification in the session is performed by laying out rendering object information used to render an object of the drawing information in a virtual 3D space based on layout information. The system comprises: establishing, upon receiving a session start request from one of the clients storing a verification target drawing information, the session to which the client storing the drawing information is able to connect; managing state information indicating a state of the 3D space for the session; receiving information of a verification input made at the clients; changing the state information upon receiving the verification input; and transmitting, to the connected clients, shared information necessary to render the 3D space.

Abstract: A cyclone separator includes a centrifugal separator which separates solid matters from a fluid mixture containing fluid and solid matters. The centrifugal separator includes a fluid introducing unit which introduces the fluid subjected to the separation of the solid matters. An electric dust collector of the cyclone separator includes a main unit and a container. The container is provided in the fluid introducing unit and houses the main unit. The main unit includes an electrostatic member, an introducing member, a voltage applying unit and a controller. The introducing member is slidable along a longitudinal direction of the electrostatic member. The electrostatic member is switched to an electrically-charged state or a non-electrically-charged state by on and off control of the voltage applying unit using the controller. Minute particles of the solid matters are adhered to the electrostatic member by an electrostatic force generated by electrical charging of the electrostatic member.
