Inventor: YOSHINO AKIRA
IPC: F17C5/02
Filed: 1982-08-23
Abstract: PURPOSE:To feed a fixed quantity of extremely low-temperature liquid without causing the hunting phenomenon of a feed signal by connecting a device comprised of a liquid reservoir at the upper section and a fixed pressure, fixed quantity liquid reservoir at the lower section to an extremely low-temperature liquid storage tank and changing the inner pressure optionally. CONSTITUTION:Control valves 19, 24 are controlled by means of the signal gas of a liquid level adjusting meter 22 so that the liquid level of a lower tank of a partition plate 14. The increased amount of the inner pressure due to the generated gas is discharged through a control valve 27 by means of the signal gas of a pressure adjusting meter 23. The valve diameter of the control valves 19, 24 and the height of a liquid reservoir 17 are designed so that the flow through the control valves 19, 24 reaches the equilibrium at a certain liquid level of the liquid reservoir 17. Therefore, the liquid reservoir 17 is invariably filled with liquid and only liquid is fed to the fixed pressure, fixed quantity liquid reservoir 18, thereby there is no fear that the liquid surface of the fixed pressure, fixed quantity liquid reservoir 18 surges and the liquid level adjusting meter 22 has a hunting phenomenon. The control valve 27 is used in conjunction with the pressure adjusting meter 23 to keep the inner pressure of a container main body 10 at a fixed (optional) value.

IPC: G06F17/50
Filed: 1988-06-13
Abstract: PURPOSE:To decrease the number of times of starting by showing the layout of a circuit element by a nodal point and a branch, allowing the nodal point to have a root pointer to the branch which is being a factor for determining its own position to the nodal point, and inspecting a positive closed circuit by following a critical branch by this root pointer. CONSTITUTION:A constraint condition is propagated to some branch, for instance, a branch 2 of (A), and position information of a nodal point 1 is changed successively so as to satisfy its constraint. Subsequently, in a state that a root pointer to the branch which is being a factor for determining present its own position is stored in each nodal point 1, a nodal point N shown in the figure in the constraint propagation direction or the branch 2 of (A) is stored in accordance with a fact that a positive closed circuit inspection is started. Thereafter, in case of having encountered the nodal point N which is stored, on the way for following successively the critical branch 2 by the root pointer, it is discriminated that a positive closed circuit exists, and a warning message is displayed. In such a case, to only the branch 2 whose constraint condition is not satisfied in a state of an initial arrangement and in which a violation flag has been set to ON, the positive closed circuit inspection is started.
