Title: System for descrambling scrambled television signal
Inventor: KARIYA TETSUO
IPC: H04N7/167
Filed: 1991-02-27
Abstract: PURPOSE:To prevent scrambled data from being easily descrambled by a person other than a specific contractor by extracting a synchronous(SYN) pattern signal during the period of a compressed vertical SYN signal and forming a horizontal SYN signal extracting window from the prescribed position of the extracted signal up to a position covering at least a horizontal SYN signal. CONSTITUTION:A SYN width information signal/SYN pattern information signal checking circuit is activated by a scrambling signal 1 and a horizontal SYN signal extracting window is generated from a horizontal SYN signal extracting window generating circuit (t1) 8 through a horizontal SYN signal extracting window position generating circuit 3 to execute descrambling operation. On the other hand, a descrambling signal is inputted to a horizontal SYN signal extraction detecting circuit 5 as an AND input together with an output from the circuit 3 to check whether a horizontal, SYN signal is or not. When the signal is not extracted yet, an output from the circuit 5 is inputted to the circuit 3 through circuits 6, 7 to determine the succeeding window position. The output of the circuit 5 is also inputted to a horizontal SYN timing signal generating circuit 9 and timing is generated from the circuit 9 and inputted to a horizontal SYN signal extracting window signal (t2) generating circuit to generate a signal (t2).

Abstract: PURPOSE: To avoid excessive consumption of power by operating the variable speed pump by constant pressure control within the range of setting time, and at the outside of the range, by operating said pump together with the pressure tank by the constant speed pump.  
     CONSTITUTION: The signals from the flow rate detector 6 and the pressure switch 8 are interlocked within the setting time band (ex. 5:00W23:00), and the pressure in the feeding pipe 5 is detected by the pressure detector, and the pressure signal from said detector is sent to the controlling device 10 to control the operation of the pump at the constant pressure as the variable pump.

IPC: F25D17/02
Filed: 1989-02-13
Abstract: PURPOSE:To sort the malfunction of a pump and the malfunction of a flow rate due to a momentary interruption of a power source by generating a power interruption display by control means when a counted value of counter means exceeds a predetermined counted value, and generating a pump malfunction display by the control means when the counted value does not exceeds a predetermined counted value. CONSTITUTION:When cooling operation of a unit 2i to be cooled by a cooling controller is started, whether the output value of each flowrate sensor 4i corresponding to the unit 2i is lowered to a predetermined value or less or not is checked at each predetermined period. If it is lowered, the number of loops in which the flowrate is lowered is counted up by counter means 8. When the counted value of the counted means 8 exceeds a predetermined counted value corresponding to a predetermined period of time, control means 6 generates a power interruption display. If the counted value of the counted means 8 does not exceed the predetermined counted value, the means 5 generates a pump malfunction display.
