Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to dispense with working in a bad place of the working environment, to efficiently, surely and completely remove shells with a short time of work and to suppress the readhesion thereof. SOLUTION: A spray device 1 arranged in a seawater flow pipe P is held in a hull 11 which is floatable in a liquid reserving section 3 formed across temporarily installed weir plates apart a spacing in a pipe axis direction in the bottom within the seawater flow pipe P. While this hull 11 is pulled and moved in the pipe axis direction via a wire taking-up and unwinding device, an aqueous amidosulfuric acid solution is injected under high pressure toward the inside wall Pw of the seawater flow pipe P from the spray device 1 to dissolve the shells sticking to the inside wall Pw of the pipe by a chemical reaction. The shells are stripped and removed by the synergy of this chemical reaction and mechanical energy by the spray.

Abstract: PURPOSE:To accurately decide a clamp level and an input sesitivity by using one of two comparators so as to set a clamp level and using the other to set the input sensitivity thereby avoiding the peak of an input signal from exceeding the clamp level. CONSTITUTION:When an amplitude VIN of a pulse signal impressed to an input terminal 15 exceeds the input sensitivity (VT-VA) set by a comparator 19, a Schmitt circuit comprising a P-channel MOSFET 26 and N-channel MOSFETs 27, 28 is operated.

The amplitude VIN of the input signal gets higher and reaches a clamp level VC being a reference voltage of a comparator 18, then the output voltage of the comparator 18 transits to a high level. As a result, an N-channel MOSFET 25 is turned on to discharge the electric charge in a coupling capacitor 16 thereby clamping a voltage VA after the capacitor couping to the clamp level VC.
