  • Patent number: 6299972
    Abstract: The microcapsule magnetic display sheet is sequentially provided thereon with a transparent front sheet, a microcapsule layer coated on the transparent front sheet and then a ultraviolet ray curable resin layer. The ultraviolet ray curable resin layer is formed by painting liquid ultraviolet raycurable resin on the microcapsule layer first and then hardening it by irradiating it with UV rays. As the liquid ultraviolet ray curable resin can fill fine gaps of the microcapsules, no hollows left between the microcapsules and the UV resin layer. As the UV resin filled in gaps shares wording pressure, the microcapsules are fully protected and hardly be destroyed. After painting the liquid UV ray curable resin on the microcapsule layer and before it IS hardened, a separable film is covered on it. While a film is covered on it, the sheet is hard and if the film is separated, the sheet is soft. So the stiffness of the magnetic display sheet can be regulated by covering or not covering a film.

  • Patent number: 6269873
    Abstract: A method for controlling heat exchange in a nuclear reactor. The reactor contains at least one thermal valve, at least one heat exchanger having a coolant flowing therein, with the heat exchanger being immersed in a pool containing a fluid. The heat exchanger is confined by a container having an upper part with an opening therein and a lower part having means for introducing the fluid through such lower part as well as means for partially or totally opening or closing said opening in the upper part and means for partially or totally opening or closing opening in the lower part. The method comprises the steps of closing the opening in the upper part of the container to thereby vaporize said fluid, in order to cause a cessation of heat exchange between the coolant and the fluid; and opening the opening in the upper part of the container to thereby cause the fluid to be heated and to rise by convection, thereby permitting heat exchange to occur between the coolant and the fluid.

  • Patent number: 6271566
    Abstract: A manufacturing method produces a semiconductor IC device which can maintain a low power consumption for electronic circuits and form gate-isolation layers of different thicknesses without increasing the manufacturing cost. The semiconductor IC device has gate-isolation layers of different thicknesses on the same semiconductor substrate surface. To form such gate-isolation layers, a silicon dioxide layer is formed in first and second regions. The dopant-concentration is adjusted in silicon dioxide layer that is to have a thickness different from the above silicon dioxide layer thickness in the second region B. A carbon-containing semiconductor layer is selectively formed in either the first region or the second region. Therefore, there is no need for additional steps for forming silicon dioxide layers of different thicknesses in the first region and in the second region.
