    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: In a golf ball comprising an elastic core, an intermediate layer of at least one layer, and a cover which is provided on its surface with a plurality of dimples, wherein the cover has a gage of 1.0–1.5 mm, the intermediate layer has a gage of 1.0–2.0 mm per layer, the golf ball in its entirety has a specific gravity of 1.128–1.145 g/cm3. On account of an optimum specific gravity in a relatively high range, the ball is improved in flight performance.
