Filed: 1979-12-17
Abstract: PURPOSE: To reduce extremely the start/stop frequency of a pump and thus increase the storing effect of a storing tank, by giving a start/stop or speed reduction to the pump installed to the specified drainage route so as to secure a convergence to a specified water level.  
     CONSTITUTION: The drainage routes 1W3 are installed in parallel to the water storing tank 4. These drainage routes contain the pumping pipes 1aW3a with their lower ends opened in the tank 4 and the upper ends connected to the common water pipe 5. When the water level of the tank 4 is lower than the lower limit value 1' the pumps 1pW3p of the routes 1W3 have no working. Then the pump 1p of the route 1 starts working when the water level of the tank 4 increase up to the upper limit value h 1 . Thus the water in the tank 4 is exhausted. Then the motor 2m of the pump 2p on the route 2 is also driven to be then stopped with a reduction of speed when the water increasing speed of the tank 4 exceeds the exhaustion capacity of the route 1 in spite of the full-speed rotation of the pump 1 and then the water level 6 increases up to the upper limit h 2 . As a result, the start/stop frequency of the pump can be reduced greatly to increase the storing effect of the tank 4.

Title: Alarm sending-out digital repeater system
Inventor: KINOSHITA KATSUMASA
IPC: H04J3/08
Filed: 1993-07-02
Abstract: PURPOSE:To constituts the repeater system so that it is small in size and can be arranged in many parts, and a spot in which a fault is generated can be grasped in an early stage and precisely by imparting an alarm sending-out function instead of a disdcriminating and reproducing means in a fundamental function of a reproducing repeater system. CONSTITUTION:A receiving signal is applied to a signal switching means 13, and also, subjected to waveform shaping and amplified by a shaping and amplifying means 2, and timing information is extracted by a timing restoring means 3. In the case the timing information cannot be extracted, a timing loss detecting means 10 outputs a timing loss signal, and also, impresses it as a switching signal to the signal switching means 13. An alarm generating means 12 generates an alarm signal by this timing loss signal and applies it to the signal switching means 13. The signal switching means 13 allows a normal time signal to pass thorugh as it is, when the timing is extracted normally, but is switched so as to allow the alarm signal from the alarm generating means 12 to pass through, when the timing information cannot be extracted, and sends out the alarm signal to a transmission device of the post-stage instead of the normal time signal.
