    摘要： The problem to be solved by the present invention is to provide a method for continuously and effectively producing an aliphatic polyester having an increased molecular weight which prevents evaporation of diisocyanate at the step of mixing the diisocyanate with the aliphatic polyester prepolymer in a molten state at a temperature not lower than the melting point of the prepolymer and enables uniform mixing of the diisocyanate with the aliphatic polyester prepolymer. In order to solve this problem, the present invention provides a method for producing an aliphatic polyester having an increased molecular weight comprising the steps of: (i) quantitatively injecting a diisocyanate into an aliphatic polyester prepolymer which has a number average molecular weight of 5000 or higher and has terminal hydroxyl groups and in which at least one acid component is a succinic acid compound, in a molten state at a temperature not lower than the melting point thereof, wherein the amount of diisocyanate is equivalent to between one tenth and two times the amount of the hydroxyl groups in the aliphatic polyester prepolymer, (ii) quantitatively and continuously mixing the diisocyanate-containing aliphatic polyester prepolymer obtained at step (i) by a static mixer, discharging same from the static mixer, and then supplying same to a coupling reaction tank, and (iii) reacting the aliphatic polyester prepolymer with the diisocyanate in the coupling reaction tank.

    摘要： A fuel cell system is provided with a plurality of cell units, a feeding channel, a bypass channel and a control unit. The cell units generate power by feeding hydrogen-containing gas an oxygen-containing gas separated from each other and then having them flow and join with each other. The feeding channel has an ejector arranged therein for refluxing exhausted hydrogen-containing gas exhausted from the cell units back to the cell units. The bypass channel has the hydrogen-containing gas flowing to the cell units bypass the ejector. The control unit includes a gas feeding pressure varying section that is programmed to make the hydrogen-containing gas flow in the bypass channel, and, at the same time, vary the pressure of the hydrogen-containing gas flowing in the feeding channel upon determining a flow rate of the hydrogen-containing gas flowing in the feeding channel is over a prescribed level.

    摘要： Generally disclosed is a golf ball having a core and a cover layer. The cover layer includes areas that are hard corresponding to the dimples, and areas that are soft corresponding to the land between the dimples. The cover layer may be selectively treated, such as by heating, to achieve a difference in hardness using a single cover layer material. Alternatively, the cover layer may be selectively coated with a coating material having a different hardness. As a result of the arrangement of the hard dimples and the soft land, the golf ball achieves reduced spin, and greater distances, when struck with a larger force (such as during a dive) while also achieving increased spin, and better control, when struck with a smaller force (such as during a chip).

    摘要： A multi-piece golf ball includes a core 30–40 mm in diameter, an intermediate layer including an outermost layer 0.5–2.0 mm thick, and a cover 0.5–2.0 mm thick. The core is a rubber composition mainly containing polybutadiene. The outermost layer is a resin material containing an ionomer resin in an amount of 30% by weight or more. The cover material is obtained by dispersedly blending a silicone powder in a main resin containing an ionomer resin in an amount of 50% by weight or more. The hardness of the outermost layer is harder than the hardness of the core's a center portion. The hardness of the cover is harder than the hardness of the outermost layer. A difference in hardness between the cover and the center portion of the core satisfies a relation of 10≦(Durometer D hardness of cover−Durometer D hardness of center portion of core≦40.
