摘要:
The length portion of part of a multiband superconductor line 10 is used as a closed circuit line part Rc that constitutes part of a closed circuit allowing passage of an electric current Io generated by an electric current source 12. Meantime, the line part extending and continuing into the closed circuit line part Rc is used as an open circuit line part Ro adapted to serve as an open circuit regarding the electric current source 12. By keeping the multiband superconductor line 10 under a temperature environment falling short of the critical soliton temperature and injecting a nonequilibrium electric current Io from the electric current source 12 into the closed circuit line part of the multiband superconductor line, it is rendered possible to induce generation of an interband phase different soliton So. The generated interband phase difference soliton So is forwarded as separated from the electric current Io to the open circuit line part Ro and is made to run therein. The open circuit line part Ro is provided with a Josephson junction 15 and consequently enabled to induce extinction of the interband phase different soliton So that has advanced thereto, during which time the voltage generated by the AC Josephson effect is detected with the voltage detecting device 13.

摘要:
A control method is proposed that controls inter-component phase difference solitons by using splitting or fusion caused by the interaction between inter-component phase difference solitons themselves, without the need for application of external energy. By using a line structure (10) in which an inter-component phase difference soliton propagation line through which an inter-component phase difference soliton (So) which can exist in a superconducting environment can travel is divided into a plurality of branch lines (10-1 and 10-2) at least at a branch end (Po) set in the middle of the line, an inter-component phase difference soliton (So) in a main line (10M) which is an undivided line portion is allowed to be split and to enter the plurality of branch lines (10-1 and 10-2) without a supply of external energy, or inter-component phase difference solitons (So1 and So2) in the respective branch lines (10-1 and 10-2) are fused together without a supply of external energy, whereby an inter-component phase difference soliton (So) is allowed to propagate through the main line (10M).

摘要:
Outer cables disposed in a box girder in the longitudinal direction of a box girder bridge to prestress the box girder each have a transparent sheath made of a transparent polyethylene resin, vinyl chloride resin, polypropylene resin or the like, thereby allowing the grouting condition in the sheath to be inspected reliably and easily. If a colored grout is filled, the filling condition can be inspected even more reliably and easily. In addition, it is possible to readily find a portion left unfilled after the grout has hardened and to refill it for repairing by using openings for injection and ejection made at each side of the void left.
摘要:
A joint made between prestressing strands with a prestressing strand coupler is covered with a transparent coupler sheath having a retarded-hardening resin filling material injection opening and discharge opening provided in a tube wall thereof, and a resin filling material is injected into the transparent coupler sheath from the injection opening to fill the coupler sheath with the filling material. Thereafter, the whole outer peripheral portion of the prestressing strand joint, including the coupler sheath, is embedded with placed concrete. Tension is applied to the prestressing strands after the concrete has hardened and before the resin filling material hardens, thereby completing an excellent prestressing strand joint structure. According to the present invention, the filling condition of the resin filling material in the coupler sheath around the prestressing strand joint can readily be confirmed by visual observation. Therefore, the operation of filling the filling material can be carried out completely. Further, the wedges present in the prestressing strand coupler are allowed to properly bite into the prestressing strands in response to the prestressing strand tensioning operation performed before the filling material hardens. Thus, a superior joint structure is provided.

A variable gain amplifier has a first amplifier circuit whose gain is A/n times (A being a real number excepting "0", and n being a real number larger than 1); a second amplifier circuit whose gain is A(n-1/n) times; level converter for level converting an output signal from the second amplifier circuit at a ratio corresponding to a level of a gain control signal having a predetermined level controllable range and at a ratio of 1/(n+1) at a central level within the level controllable range of the gain control signal; and an adder circuit for adding together an output signal from the level converter and an output signal from the first amplifier circuit at the ratio of 1:1. The variable gain amplifier has a gain controllable range of among 1/n.about.1.about.n times as the level of the gain control signal changes among the minimum level.about.the central level.about.the maximum level. When the gain of the second amplifier circuit is set to A(m-1/n) times (m being a real number larger than 1) and a level conversion ratio of the level converter is set to (1-1/n)/(m-1/n) at the central level of the gain control signal, the variable gain amplifer having the gain controllable range of among A/n.about.A.about.mA times is realized.
