Title: Device start-up system
Inventor: TAKEKOSHI YUTAKA
IPC: H02J1/00
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a device start-up system for setting information required for the operation of the device in the register in a circuit package in which the time to be elapsed before the actual operating state is brought about is shortened. SOLUTION: Operational information being set in the register in a circuit package inserted into each slot (a) is stored in the memory in a bus interconnection board (s) immediately before the operation. At the time of starting up a device, the operational information stored in the memory is set in the register in each circuit package thus bringing about a temporary operating state. Subsequently, the operational information stored in the memory is compared with information required for current operation and when they do not match each other, the current operational information is set again in the register. Since a temporary operating state is brought about prior to an actual operating state, the time to be elapsed before actual operating state is brought about is shortened.

Title: Chilling unit
Inventor: NIIJIMA HIROSHI
IPC: F25D17/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the air from remaining in a brine tube by evacuating the brine tube and encapsulating brine in the brine tube. SOLUTION: At the time of encapsulating brine in a brine tube 10 during installation or repair work thereof, the brine tube 10 is coupled with a vacuum pump, or the like, and evacuated before brine is encapsulated therein. A large diameter part 10a is provided at a high position H of the brine tube 10. Current velocity decreases at the large diameter part 10a without increasing the flow resistance of brine to cause stagnation of the air (fine bubbles K) being mixed due to insufficient evacuation. The fine bubbles K standing at the large diameter part 10a can be discharged easily by opening an on/off valve 17. Since the air in the brine tube 10 can be purged at the time of encapsulating brine, stagnation of the air in the brine tube 10 can be eliminated.
