Abstract: PROBLEM TO BE SOLVED: To smoothly perform the virtual activity of a relevant participant when a terminal computer is connected to a central computer again even after the virtual activity processes or stops in the central computer while the virtual activity is separately performed in the state of temporarily disconnecting the terminal computer from the central computer. SOLUTION: Among terminal computers 21, 22 and 23 connected through a communication network 11 to a central computer 10, the terminal computer 21 is temporarily disconnected from the communication network 11. In this case, a virtual space/virtual time concerning the virtual activity cooperatively performed before is applied to a storage device 21d and the terminal computer 21 performs the virtual activity separately from the central computer 10. The local condition of the virtual space provided as a result is integrated into the central condition of the virtual space on the side of the central computer 10 in the case of new connecting to the central computer and the virtual activity to be newly cooperated is continued.

Title: Method and article for improving cooling efficiency of flow of gaseous coolant flowing inside substrate
Inventor: FRIC THOMAS FRANK
IPC: F23R3/42
Filed: 2000-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce the separation of coolant flow from the high temperature surface of a substrate, by tilting a passage hole at a specific angle to the substrate, by making the depth of an exit point smaller than the length of the passage hole, and by contacting the coolant flow with the area which is larger than that of the high temperature surface. SOLUTION: The surface 12 of a substrate 10 is a hot surface, while a surface 14 is a cold surface. A passage hole 16 passes through a hole length part 18, and comes out on the cold surface by a hole bottom 20. The distance between both surfaces is equal to the thickness of a normal substrate, and this distance is within the range of about 20 to 2000 mil. The hole is located at a certain angle to the horizontal surface of the normal substrate, and it is in the range of about 20 to 45 deg. in many cases. The angle of the hole is determined by the shape of parts, cooling conditions, the air flow on the substrate, and so on. In order to maximize the cooling efficiency, the coolant flow coming off of the hole preferably contacts with the hot surface 12 as much as possible.  Moreover, it is important that the exit point, for example the depth of a crater, is smaller than the length of the passage hole. This depth is preferably reduced about 50% of the length of the passage hole.

SOLUTION: An analytic model provided with a virtual slot having its upper end closed is used as a waterway, and a continuous equation and an equation of a motion of water regarding the analytic model and a continuous equation and an equation of motion of air are used to estimate the state quantity of water. To estimate the state quantity, the mentioned four equations are differentiated by the Preissman four- point implicit finite-difference scheme, the differentiated equations are processed by Taylor expansion nearby an estimated value of the state quantity and linearlized, and unknown state quantities at points in the waterway are erased, thereby obtaining the linear characteristic equation of the waterway.  According to the linear characteristic equation, state quantities corresponding to the respective positions corresponding to the time elapse are obtained through convergence operation based upon the Newton- Paphson method. Thus, the virtual slot having its upper end closed is used to estimate the state quantities of the water while the behavior of air is taken into consideration even if the waterway has an air pool on the top surface of the liquid.
