Abstract: A liquid crystal display device with improved visual recognition is provided which includes: a first liquid crystal cell; a second liquid crystal cell; two cross polarizers disposed on both sides of a two-layer structure panel including the first and second liquid-crystal cells along a normal direction of the substrates; a light source capable of emitting lights of a plurality of colors; and a control circuit for time sequentially dividing one frame into a plurality of subframes, emitting light of a predetermined color in each subframe, synchronously with light emission, controlling a state of light transmission and light shielding of a plurality of display areas of said two-layer structure panel including said first and second liquid crystal cells, wherein the first and second liquid crystal cells are structured in a mutual optical compensation relation in both a driving state and a non-driving state.

Abstract: A method of making a composite foamed and shaped article including in the first step in which a thermoplastic resin powder is filled in a slush molding die to form a first resin layer, a second step in which a mixed powder consisting of a heat decomposable foaming agent and the thermoplastic resin powder is filled in the die in which the first resin layer was already formed, to form a second resin layer on the surface of the first resin layer, and a third step in which the heat decomposable foaming agent is made to foam by heat treatment to form a final product of a composite foamed and shaped article wherein the slush molding die is pre-heated by an infrared heating method.

Abstract: A method for rotationally molding synthetic resin dolls using an automatic control mechanism, a mold holding mechanism, a robot mechanism having a mold cover opening and closing means, a mold releasing means for releasing a molded product from the mold, mold release detecting and cleaning means; a raw material charging means, and a heating and cooling means. The method includes detecting the mold release of the molds opened by the mold holding mechanism and cleaning the molds. Quantitatively charging a raw material of thermoplastic synthetic resin into the mold in a solid state and closing the cover. Inserting the mold into a heating furnace of a heating mechanism and rotating the mold to form a synthetic resin molten skin layer on the inner wall of the mold. Once the layer is formed the mold is moved into a cooling chamber of a cooling mechanism and the skin layer is solidified while continuing to rotate the mold. When the layer is solidified the mold is moved to the mold releasing unit.
