  • Patent number: 6303422
    Abstract: A semiconductor memory in which a layout margin at the contact hole between wiring layers of a SRAM does not need and the wiring capacity at bit lines is reduced and the high speed processing is made to be possible is provided. The SRAM is constituted of a pair of driving transistors Qd1 and Qd2, a pair of transferring transistors Qt1 and Qt2, high resistance loads R1 and R2, a pair of bit lines BL1 and BL2, and a VCC line and a GND line. Gate electrodes of each transistor and word lines are formed at a first layer, the high resistance loads are formed at a second layer, the VCC line and the GND line are formed at a third layer, and the bit lines are formed at a fourth layer. A shared contact hole using for connecting the high resistance loads to the source/drain area of transistors does not penetrate the other conductive layers. Therefore, the layout margin between the shared contact hole and the other conductive layers becomes unnecessary and the reduction of the cell size becomes possible.

  • Patent number: 5407610
    Abstract: In a method for molding a sheet which includes thermosetting resin materials reinforced with glass fiber or carbon fiber, the sheet includes a covering film always existing in a side which is not in contact with a mold face and, when the sheet and covering film are shaped along a mold face and the sheet is thermally cured, apparatus for dealing with an accidental breakage of the covering film is arranged on the side of the sheet which is covered by said covering film.

  • Patent number: 5237950
    Abstract: An astride-type small boat sails on water under propulsive forces generated by a propulsion unit driven by an engine mounted in a hull assembly. A driver's seat is disposed on the hull assembly rearwardly of a steering device mounted thereon, with foot spaces defined on opposite sides of said driver's seat. A passenger's seat displaced from the driver's seat in a transverse direction of the hull assembly. The passenger's seat is displaced from the driver's seat in a fore-and-aft direction of the hull assembly.

  • Patent number: 5234756
    Abstract: This invention provides a sheet for molding a fiber-reinforced resin finishing the fiber-reinforced resin moldings surface under an excellently colored condition.A sheet for molding of this invention comprises a fiber-reinforced resin layer and a colored surface resin layer being laminated and has, in the fiber-reinforced resin layer, a fiber-reinforced colored resin layer adjacent to said surface resin layer and colored in a color similar to that of the surface resin layer, and a fiber-reinforced transparent resin layer arranged on a surface in a side reverse to the surface resin layer and having a curing character by ultraviolet rays.

  • Patent number: 5211893
    Abstract: The method for molding a resin reinforced with fiber wherein a resin sheet reinforced with fiber is positioned juxtaposed a face of a mold, which is either one of a female mold or a male mold, and then hardened, but before molding, modifying the viscosity to different levels in different portions of the resin sheet. Thus, it is possible to surely prevent occurrence of a partial difference in thickness of the moldings or, if necessary, to partially change these thicknesses according to predetermined values.
