Title: Automatic drainage system
Inventor: ANDO IWAO
IPC: F24F13/22
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an economical automatic drainage system. SOLUTION: When a liquid level in a liquid storage tank 4 goes up to the specified normal drainage starting level L2, a valve gear 20 interposed in a piping system of a siphon type drain pipe 12 is opened into operation. In succession, the liquid level in the tank 4 goes up to the specified forced drainage starting level L1, a forced drainage means 7 starts its operation. After the liquid is filled up in the drainage pipe 12, this forced drainage means 7 comes to a stop. Supposing the liquid level in the tank 4 goes down up to the specified normal drainage stop level L3, the valve gear 20 is closed of operation.  When the liquid level in the tank 4 goes up to the specified normal drainage starting level L2 again, the valve gear 20 is reopened into operation, and thereby gravitational drainage continues until the liquid level in the tank 4 goes down up to the normal drainage stop level L3 by a siphon action in the drainage pipe 12. Subsequently, the gravitational drainage due to this siphon action is repeated by operational control alone of the valve gear 20.

Title: Mobile communication system and simple synchronization method between base stations used therefor
Inventor: NORIMATSU HIDEHIKO
IPC: H04W92/12
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a simple synchronization method between base stations that can reduce search time and suppress unnecessary signaling in the case of hand-over. SOLUTION: Each receiver of a plurality of base stations detects an incoming signal from a mobile set, to calculate a distance function with the mobile set (step S15), and transmits the value to a base station controller (step S16). Upon the receipt of the difference between respective received times of outgoing signals of the base stations from the mobile set (steps S17, S18) the reference base station transmits the difference between the respective, received times to the base station controller (step S19). The base station controller calculates the difference of transmission timing between the reference base station and an object base station on the basis of data from the object base station, and informs base stations other than the reference base station about the difference, so as to make the other base stations change the transmission timing of the outgoing signal.
