IPC: G06F12/00
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To delete an unused program in its saved state or after a fixed period and to attain the effective use of resources by saving once an installed program and then restoring and executing it at need. SOLUTION: The installed resources 2 include an installed program and consists of files F21 and F22. A resource saving means 3 saves the resources 2 into a storage as the saved resources 4 consisting of both files F21 and F22. The resources 4 are not executable as they are and then can be executed when they are restored into their original directory such as the installed resources 7. A location management means 5 produces a management list F23 at the unsaved original directory position when the executable resources 2 are saved, and then registers the file directory of the saving destination in the list F23. A resource restoration means 6 refers to the list F23 to restore the resources 4 into the resources 7 which are executable. Then, an OS 8 performs the general control.

Title: Water level control system for bath tub
Inventor: KAGEYAMA NAOKI
IPC: F24H1/46
Filed: 1989-06-02
Abstract: PURPOSE:To remove air in a piping and provide a stable water level control by a method wherein a bath tub is connected to a water supplying part, a pressure sensing means for use in sensing a water pressure through a piping to supply water to the bath tub and a water level control means for supplying auxiliary water to the piping are provided. CONSTITUTION:A pressure sensor 14 for use in sensing a pressure of a piping 8 for expressing a water level of a bath tub 2 is connected to a branch pipe 12. As air enters a piping 8, a detected pressure of a pressure sensor 14 may detect a pressure differing from an actual water level within the bath tub 2. In order to prevent this erroneous operation, a hot water feeding control 16 may compare a detected water level hS of he pressure sensor 14 with a set water level hF. In case that it is judged that the detected water level hs is lower than the set water level hF, a three-way valve 45A is opened toward the piping 8 so as to perform an auxiliary supplying of water from the piping 8. This auxiliary water is such an amount as one capable of removing air from the piping 8. After this operation, the three-way valve 45A is closed to detect the water level and if the detected water level hS is equal to the set water level hF, the water supplying control is completed.
