  • Publication number: 20150017390
    Abstract: According to a molding method for a fiber reinforced composite material, a cavity forming surface 13 of a second mold 12 with a recessed portion 14 for molding a thick portion is brought into contact with a fiber reinforced composite material 15. The fiber reinforced composite material 15 is heated in a state in which the temperature of the cavity forming surface 13 is higher than that of a cavity forming surface 11 of a first mold 10. After that, the first mold 10 and the second mold 12 are closed with a pressure to the fiber reinforced composite material 15 so as to pass the fiber reinforced composite material 15 into the recessed portion 14. This can integrally mold the thick portion with the main body of a molded component.

  • Patent number: 8350976
    Abstract: A liquid crystal display device includes an array substrate, a counter substrate and a liquid crystal layer having liquid crystal molecules interposed therebetween. The liquid crystal molecules are aligned in a direction normal to a surface of the substrates under a condition where no electrical voltage is supplied between a picture electrode and a counter electrode. An alignment control device is provided at the counter substrate and configured to control the alignment of the liquid crystal molecules under a condition where an electric field is applied between the picture electrode and the counter electrode. A scanning line crossing a pixel is divided into first and second segments.
