Title: Conveying mechanism for liquid such as water
Inventor: OGATA HARUKI
IPC: F16L55/07
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To prevent liquid from leaking out even if a device is toppled. SOLUTION: An annular drain passage 121 for guiding water to a tank forms a passage extending from a water receiving drain port 122 to a main body drain port 123 through one round. During the operation of a device, water is contentiously allowed to flow through the annular drain passage 121. When an air cleaner falls caused by some external factors during the operation of the device, flowing water is accumulated on the lower side of the annular drain passage 121, and the annular drain passage 121 is completely blocked. When water leaks out from the main body, it is necessary to allow air to flow into the main body, however, water accumulated in the annular drain passage 121 disturbs inflow of air. Accordingly, leakage of water to the outside is prevented.

Title: Tri-state value detection circuit
Inventor: SUZUKI HIDEHIKO
IPC: H03K19/00
Filed: 1988-01-14
Abstract: PURPOSE:To surely identify the states of high impedance, high potential or low potential by detecting the tri-state value not only depending on the level of the input potential but also an oscillated output of a Schmitt trigger inverter caused at a high impedance input detected by a clock detection circuit. CONSTITUTION:Since the Schmitt trigger inverter 1 is oscillated at a time constant caused due to the delay between the input and output with an input 11 at a high impedance, an output 13 of a clock detection circuit 3 is at a high potential. With the input line 11 at a high potential, the output 12 of the Schmitt trigger inverter 1 goes to a low potential and the output 13 of the clock detection circuit 3 goes to a low potential, and further, with the input line 11 at a low potential, the output 12 of the Schmitt trigger inverter 1 goes to a high potential and the output 13 of the clock detection circuit 3 goes to a low potential. Thus, a stable and sure detection result is obtained against the fluctuation of a power supply voltage and of an input signal level.
