A construction having a damping device for damping vibration having steel wire cables 20 having both ends fixed on the sides of the building 10, the steel wire cables 20 are tautly and obliquely provided on the building 10 so that one side and the other side of the steel wire cables 20 cross at only one point in front view. Since the steel wire cables 20 do not exist in the horizontal direction, the length of the steel wire cables 20 is shorter as compared with the prior art. Accordingly, extension of the steel wire cables 20 decreases, the mechanism is simpler, and maintenance is also simplified.

Construction having a damping device

A method of manufacturing extruded flat multihole aluminum tube for heat exchangers is disclosed, which is characterized in that, in the hot extrusion of flat multihole Al-Cu or Al-Cu-Mn tubes, a plurality of tubes are extruded side by side in the longitudinal direction and Zn is flame sprayed onto both even surfaces of the tubes in the vicinity of the extrusion exit of the tubes to cover both even surfaces of the extruded tubes with Zn. The covering level of Zn is 3 to 30 g/m.sup.2.

Method of manufacturing extruded flat multihole aluminum tube for

Al and Al alloy materials for a fin are disclosed which contain Fe of 0.2% or less and Si of 0.1% or less and exhibit improved thermal conductivity, sacrificial anode effect and sagging resistance. Also, a heat exchanger having a fin made of the Al and Al alloy material incorporated therein is disclosed. The heat exchanger is lightweight and excellent in corrosion resistance and heat radiation.

A heat exchanger made of aluminum alloys comprising a tube made of an aluminum alloy consisting of 0.2 to 1.0 wt % of Cu and the balance Al and inevitable impurities, and fins jointed to the tube, at least a portion of each fin being formed from another aluminum alloy exhibiting and electrochemical potential value lower than that of the aluminum alloy from which the tube is made, so as to provide a sacrificial corrosion effect. Disclosed also is an aluminum alloy material having superior hot-extrusion characteristics and pitting corrosion resistance suitable for use as the material of heat exchanger tubes, the aluminum alloy material consisting of 0.2 to 1.0 wt % of Cu and the balance Al and inevitable impurities.

Heat exchanger made of aluminum alloys and tube material for the heat

A root canal irrigation means for treating decayed teeth including a liquid vessel filled with water, antiseptic solution or some other kind of liquid, a pumping means for pumping the liquid from the liquid vessel under pressure, and a discharge needle shaped like an injection needle coupled to the outlet of the pumping means and which feeds the liquid under pressure to a dental focus when the pumping means is operated. The pumping means comprises a reciprocating pump which is coupled to the outlet of the liquid vessel.

Method and apparatus for root canal irrigation
