Filed: 1988-05-26
Abstract: PURPOSE:To execute a delay test by a ring oscilloscope in a logic circuit containing an FF by connecting an output terminal of a 2-multiplying circuit to a clock input terminal and connecting an input terminal of the 2-multiplying circuit to a data input terminal. CONSTITUTION:A data input D of an FF 1 is connected to an input of a 2-multiplying circuit 8, and a clock input terminal CP of the FF 1 is connected to an output of the circuit 8. In this state, the circuit 8 operates so that an output frequency becomes two times of an input frequency. When an output terminal of this circuit 8 is connected to a clock input of the FF 1, and the input terminal CP of the circuit 8 becomes a data input, the frequency of the clock input terminal of the FF 1 operates by two times of the input frequency. An output waveform of the FF 1 which has been operated by this clock waveform becomes 1/2 of a clock waveform frequency, and becomes the same frequency as that of an input waveform. As a result, the frequencies of the input waveform and the output waveform of the FF 1 coincide, and by returning this output to the input terminal CP, a ring oscillator can be constituted easily.

IPC: E03D9/08
Filed: 1995-05-29
Abstract: PURPOSE: To detect whether a water storage volume is at a suitable level or not by internally fixing an electrode to a tank body made of an insulation raw material, detecting an alternating current flow across the electrode, and outputting the prescribed control signal, depending on the existence or non-existence of the current flow. CONSTITUTION: Water is supplied to a tank 1 and, then, alternating current is made to flow across electrodes 2 and 3 laid therein. In this case, the constants of resistors R1 and R2 are decided, so that suitable bias is applied to a detector circuit, due to a current amount and suitable base current flows. When the resistor R1 is kept in a half-fixed state with a constant resistor and a variable resistor connected in series, a water level is properly detected by adjusting sensitivity to a level suitable for water quality. Also, an air pocket is formed to prevent the adhesion of water scale around the fixed sections of the electrodes 2 and 3. In addition, the occurrence of improper electric conduction via water scale adhering to the inner side of the tank 1 is prevented.  According to this construction, a water level can be easily and properly detected without any trouble due to water scale or the like in the tank 1.
