Filed: 2010-01-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a seat cushion material including an antenna electrode at low cost.  <P>SOLUTION: The cushion material 22 including the integrated antenna electrode 21 composed of an aggregate of conductive microparticles 37 on the surface is molded by magnetically attracting ferromagnetic conductive microparticles 37 to a die magnet 35 disposed on a cavity surface 34 of a molding die, collecting the surplus conductive microparticles 37 by a conductive microparticle collecting magnet 39, and foaming an urethane resin stock solution 40 injected into the molding die. With this structure, steps for printing the antenna electrode 21 on an insulation sheet or pasting the antenna electrode 21 to the cushion material 22 are not necessary, and further, positioning of the antenna electrode 21 to the cushion material 22 is not necessary either. As a result, the cost of manufacturing the cushion material 22 can be reduced. Further, as the conductive microparticles 37 magnetically attracted to the die magnet 35 are not moved when the urethane resin stock solution 40 is injected and foamed, the antenna electrode 21 of the uniform thickness can be formed, and voids are not formed on the surface of the cushion material 22.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To produce a cellulose acylate film the Re (in-plane retardation) of which is made larger while increasing the refractive index in the width direction in spite of a cooling flow casting method.  <P>SOLUTION: A wet film 12 stripped from a drum is introduced into a tenter. In the tenter, each side of the wet film 12 is held by a pin. A crystallization step of heating the wet film 12 to the temperature equal to or higher than the crystallization temperature Tc thereof to promote crystallization is carried out in the tenter. A width shrinkage step of shrinking the width of the wet film 12 is started before the crystallization step is completed. The width shrinkage is carried out so that the wet film 12 is not prevented from being shrunken in the width direction due to drying. This width shrinkage is a process where a crystalline portion of cellulose acylate is oriented in the width direction X. After the crystallization step is completed, a width expansion step of expanding the width of the wet film 12 is carried out. This width expansion is a process where an amorphous portion of the cellulose acylate is oriented in the width direction X.  <P>COPYRIGHT: (C)2011,JPO&INPIT
