Inventor: NAKAGAWA KENICHI
IPC: E02B3/06
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a multiple nature type steel sheet-pile revetment having a positive function of purifying water in addition to structural functions and being excellent in the function of improving a view and that of protecting and raising an ecosystem. SOLUTION: A cage-shaped frame 3 filled with gravel 4 is inserted into the water- area-side recess part of a steel sheet-pile revetment comprising asymmetrical U-shaped steel sheet-piles 1 connected together. A guide member 2 for insertion is mounted in the position of a water-area-side opening in each asymmetrical U-shaped steel sheet-pile 1. Water purification is effected by the packed gravel 4 through oxidation due to contact between pieces of the gravel. Aquatic plants are placed on top of the gravel 4 to provide the effect of improving a view and that of protecting an ecosystem. Since the subterranean stems of the aquatic plants grow by absorbing organic matter and nutrient salts between the pieces of the gravel 4, the need to add fertilizer is eliminated, and clogging between the pieces of the gravel 4 and the anaerobic state of biofilms on the surfaces of the gravel 4 are prevented, whereby the effect of oxidation due to contact between the pieces of the gravel is maintained over a long period. When the gravel or the plants need to be replaced because of clogging of the gravel 4 or the poor development of the plants, the cage-shaped frame 3 is easily removable.

Abstract: PROBLEM TO BE SOLVED: To enhance the adhesion strength of core material and a porous body so as to suppress the pole plate deformation or the falling-out of the active material at an active material impregnation time and to enhance an efficiency discharge characteristic by forming fine recesses and protrusions of a specific diameter and depth on the surface layer of conductive core material. SOLUTION: Nickel porous bodies 2 contained in a nickel slurry are hooked with fine recesses and protrusions 1 on the core material surface of a bored steel plate 3, so that the contact area of the bored steel plate 3 and the nickel porous bodies 2 is increased. Therefore, substrate strength after sintering is enhanced, and the deformation of an pole plate or the falling-out of active material in respective processes such as active material impregnation, formation, battery group constitution can be suppressed.  With respect to 2 to 3μm average particle diameter of the nickel porous bodies 2, when the diameter of the core material surface recesses and protrusions 1 is 0.01μm or less, a pore diameter is too small, and reversely, when the diameter is 10μm or more, the pore diameter is too large so that the nickel powder 2 cannot be efficiently hooked with the core material surface. Therefore, the diameter of the recesses and protrusions is set to be 0.01 to 10μm, and the depth, to be 0.1 to 5μm.

IPC: F24H1/14
Filed: 1989-02-17
Abstract: PURPOSE:To prepare desired temperature hot water during a short period of time by forming a first passageway of water circulating through a hot water storing insulating container and a second water circulating passageway for bypassing said hot water storing insulating container on the downstream side of a heat exchanger, and providing an electric heater on said hot water storing insulating container. CONSTITUTION:Even when hot water is not supplied, an electric heater 6 is operated to raise hot water in a hot water storing insulating container to a predetermined temperature and keep the same at that temperature. Once a hot water outlet 8 is opened for the hot water to start the effluence thereof, first and second water circulating passageways 4, 5 become a water circulating state, the hot water in which passageways is stored and discharged from the hot water outlet 8. Additionally, once a flowing water switch and the like detects water flowing through a water circulating system 2 owing to the start of the effluence of the hot water, a burner 9 is actuated to start temperature rise in a heat exchanger 1. Thus, the hot water rising to the predetermined temperature is discharged from the hot water outlet 8. Since remaining water in the water circulating system 2 is stirred with the hot water stored in the hot water storing insulating film 3 in the first water circulating passageway 4 and discharged, there is not fear that the cooled remaining water is discharged at the same temperature as it is.
