Title: Water overflow preventive mechanism for flush toilet stool
Inventor: IKEDA SHUJI
IPC: E03D11/13
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the overflow of water from a flush toilet stool by setting a water level sensor at the flush toilet stool, issuing an alarm in response to the detection of the water level exceeding a predetermined level by the water level sensor, and maintaining a flush valve in an opening-disabled-state. SOLUTION: When a flush toilet stool 3 is clogged by a foreign matter, the water level in the toilet stool 3 ascends relative to a normal state when water is flushed, thereby energizing a water level sensor 4. Then, a water level detecting section 9 of a main body device 1 detects a predetermined water level and generates a detection signal, and a warning device 11 is activated by the detection signal, thereby sounding a buzzer. Further, a power source control section 8 is activated to interrupt power supply to a flush valve device 2 and to light up an indicating lamp 10. Since the power source control section 8 interrupts power supply to the flush valve device 2, a protective function for power failure is activated whereby the flush valve is forcedly kept in a closed state.  Accordingly, even if a signal device 5 is operated, flush water is not supplied, thereby preventing overflow of water.

Title: Power source system
Inventor: MASUO YOSHIAKI
IPC: H02J3/38
Filed: 1983-05-27
Abstract: PURPOSE:To prevent an excess cross current due to refiring of an output switch by connecting an auxiliary switch in parallel with an output switch through a serial impedance and delaying to open the auxiliary switch to the output switch. CONSTITUTION:An auxiliary switch 10 is connected through a serial impedance 9 in parallel with an output switch 6. The switch 10 is closed simultaneously with the switch 6, but the opening operation is formed to have a certain time delay to the switch 6. When the switch 6 of one constant voltage frequency power source A is opened, a voltage between the terminals of the switch 6 becomes a voltage divided by a series impedance 9. Accordingly, the level is low, and the possibility of the refiring is eliminated. Even if the refiring occurs at the opening time of the switch 10, the magnitude of a cross current can be suppressed to the detecting level or lower if the value of the impedance 9 is suitable.
