Abstract: A cleaning system encompasses a solution reservoir to reserve a pH-adjusted solution, a gas-filling path connected to a top of the solution reservoir, to send a CO2 gas in a hollow space of the solution reservoir, a CO2 gas-cylinder connected to the gas-filling path, a solution-sending path to send the pH-adjusted solution to a pipeline of a Device-to-be-Cleaned, a cleaning-solution introduction-path connected to the solution reservoir, to introduce an original cleaning solution to the solution reservoir, for generating the pH-adjusted solution, a stock-solution tank provided at an input side of the cleaning-solution introduction-path, configured to the original cleaning solution, and a filling-pressure adjuster provided in the gas-filling path and a solution-sending-pressure adjuster provided in the solution-sending path for adjusting a filling pressure of the CO2 gas-cylinder.

Abstract: There are provided a fluid-path tester and a fluid-path testing-method capable of performing classification of abnormal-modes into a problem in a system, a leakage in a dedicated tube, a problem of a failure in a suppression pressure, and the like, an analysis of the abnormal-modes, and the like in a simplified manner. PAPS valves are included, and an abnormality emulator inspecting an abnormal condition in a fluid path of a DUT by emulating characteristics of the fluid-circuit represented by each of a plurality of abnormal-modes having possibilities of occurring in the fluid path of the DUT through pressurization of a fluid pressure using a compressor-under-test and adjustment of the fluid pressure using the PAPS valves.

Abstract: Power-feeding units to which charge-scheduled devices are connected, charge-end-point detecting-circuits detecting charging-start timing and charging-end timing, reference-charge-period determining-circuits measuring reference-charge-periods, a priority-determining circuit determining priority orders of uses of charge-scheduled devices based on the charging-periods of the charge-scheduled devices, and charging-state displaying circuits displaying under-charging or charge-completed and the priority in the use order of the charge-scheduled devices are included.
