Abstract: In a method for producing hydrophilic polymer particles, a dispersion in which an aqueous-phase component including hydrophilic monomers and a polymerization initiator is dispersed in an oil-phase component including a hydrophobic solvent is prepared. Thereafter, the hydrophilic monomers are polymerized in the aqueous phase by supplying oxygen to a reaction vessel and, while oxygen is being supplied, heating the dispersion having a reduced dissolved oxygen concentration in the reaction vessel so that the temperature of the dispersion is increases. The time from the start of reduction of the dissolved oxygen concentration of the dispersion to the start of the heating is 0.1 hour or more and 3.5 hours or less. The amount of oxygen supplied to the reaction vessel is greater than or equal to 0.02 volume %/h and less than or equal to 0.9 volume %/h with respect to the volume of the dispersion under standard conditions.

Abstract: The present invention includes two pairs of positive and negative cables are led out by dividing a pair of positive and negative terminals of a solar cell modules, and dipole connectors to which terminals are connected are formed on ends of the cables. The terminals in the dipole connector disposed on one side of the solar cell module form positive and negative plugs, while the terminals in the other dipole connector disposed on the other side of the solar cell module form positive and negative sockets. The cables include an inverse connection preventing portion which allows connection between the dipole connectors on a plug and socket side disposed between each adjacent solar cell modules when the polarities of the negative and positive terminals are the same, but which restricts connection therebetween when the polarities of the negative and positive terminals differ from each other.

Abstract: Terminal plates (30) are juxtaposed on a base plate (11) for electrically connecting positive and negative electrodes of a solar battery module (90) to cables (80) for external connection. A rectifying device (50) spans between adjacent terminal plates (30). Each rectifying device (50) has a bypass diode (52) and a metal clip (53) resiliently holds the bypass diode (52). A heat discharging sheet (40) is attached to the lower surface of the clip (53) for discharging heat generated by the bypass diode (52). Heat discharged from a heat discharging surface (40A) of the heat discharging sheet (40) is received by a heat receiving surface (90A) of the solar battery module (90) via a through hole (11B) formed in the base plate (11) and is discharged efficiently from the solar battery module (90).
