  • Patent number: 9454002
    Abstract: A wavelength selection switch (1) equipped with: an input/output unit (10) having multiple input/output ports that input/output signal light; a light-collecting mirror (14) arranged in the light path of the signal light from the input/output unit; a dispersion element (13) having a dispersion part and a non-dispersion part that does not have a dispersion effect; and multiple deflection elements (16) arranged in the direction in which the signal light is dispersed. The light-collecting mirror (14) causes the signal light from the input/output unit (10) to enter the dispersion part of the dispersion element (13), and the light that is dispersed by the dispersion element (13) is collected in the deflection elements (16) through the non-dispersion part of the dispersion element (13). Furthermore, the deflection elements (16) deflect the collected light such that the light is emitted from a prescribed input/output port of the multiple input/output ports.

    Abstract: An apparatus (2) includes: a first tank (4); a line mixer (6); a second tank (8); a cooling jacket (10); a first tube (12); a second tube (14); and a third tube (16). In the first tank (4), (i) sodium persulfate serving as a polymerization initiator and (ii) water are fed so as to obtained an aqueous solution. The aqueous solution is continuously taken out and transferred via the first tube (12) to the line mixer (6). Between the first tank (4) and the line mixer (6), water is injected into the first tube (12). The water and the sodium persulfate aqueous solution are stirred together in the line mixer (6). This stirring decreases a concentration of the aqueous solution. The resulting aqueous solution is continuously fed to the second tank (8) via the second tube (14). The aqueous solution is then continuously taken out via the third tube (16) and is continuously added to an acrylic acid (salt) aqueous solution.

  • Patent number: 8864530
    Abstract: The invention relates to a jack having a switch mechanism SW of the single-butt contact type in which an ON/OFF operation is performed by insertion/extraction of a plug P. When the plug is inserted, a displacement load is applied by the separator to a middle portion in the length direction of the movable contact piece to flex the movable contact piece while setting a basal end portion of the movable contact piece as a fulcrum, whereby a tip end portion thereof is contacted with the stationary contact piece. Thereafter, the middle portion in the length direction of the movable contact piece is flexed while setting the tip end portion as a fulcrum, to apply a contact pressure on a contact. As a result, miniaturization of the jack, and reduction of the production cost can be realized.
