Further yield in punching work and laminating work of the polarizing late is improved and a liquid crystal display device which can maintain good visibility in long term use is also provided by the polarizing plate. The acrylic resin containing film is composed mainly of an acrylic resin and is characterized in that the film contains the acrylic resin and the cellulose ester resin in a weight ratio of 51:49 to 95:5 and further contains a retardation control agent.
摘要:
Object of the present invention is to provide an acrylic-resin-containing film which exhibits high transparency, high heat resistance, and markedly improved brittleness, a polarizing plate using the acrylic-resin-containing film which improves a yield of operation such as punching of a polarizing plate or bonding panels and a liquid crystal display device which can keep to exhibit excellent visibility in long-terms usage in harsh environment. These objects have been achieved by the acrylic-resin-containing film comprising a acrylic resin (A) and a cellulose ester resin (B), or comprising the acrylic resin (A), the cellulose ester resin (B) and at least a resin (D) which is other than the resins (A) and (B) and has a glass transition temperature Tg of 120-300° C. The film is characterized in that it has a haze of less than 2%, a tensile softening point of 120-150° C. and undergoes no ductile fracture.

The method to produce the vertical alignment type liquid crystal display employs treating an optical film comprising of cellulous ester with an aqueous solution of sodium hydroxide to prepare an alkali-treated optical film; immersing a polyvinyl alcohol film in an aqueous solution containing iodine and boric acid; stretching the polyvinyl alcohol film to prepare a polarizing film; adhering the alkali-treated optical film onto both surfaces of the polarizing film to prepare a polarizing plate; and providing the polarizing plate on both surfaces of a vertical alignment type liquid crystal cell to providing the vertical alignment type liquid crystal display. At least one of the optical film has a retardation value (Rt value) in the thickness direction of from 60 to 300 nm, Rt=[(nx+ny)/2−nz]×d.

A supporting structure for a fuel tank in a vehicle includes a suspension arm fixing structure provided under the floor of a vehicle body and having a statically sufficient rigidity, the fuel tank being located so as to partially overlap the suspension arm fixing structure in the longitudinal direction of the vehicle, and a supporting member provided under the fuel tank so as to extend in the lateral direction of the vehicle being detachably fastened to the suspension arm fixing structure to bring the fuel tank into pressure contact with the floor of the vehicle body by fixing the fuel tank. The supporting member serves also as a reinforcing member for imparting rigidity to the suspension arm fixing structure so that the suspension arm fixing structure can sufficiently sustain a dynamic load during running of the vehicle.

In a semiconductor device, pining regions 105 are disposed along the junction portion of a drain region 102 and a channel forming region 106 locally in a channel width direction. With this structure, because the spread of a depletion layer from a drain side is restrained by the pining regions 105, a short-channel effect can be restrained effectively. Also, because a passage through which carriers move is ensured, high mobility can be maintained.

A pedometer (100A) includes a sensor unit (150) fixed and arranged so as to detect a body motion in a predetermined detecting axis direction, and a body casing accommodating the sensor unit (150). The detecting axis of the sensor unit (150) is arranged in an inclined manner at an inclination angle with respect to an attachment surface (122) to a body of the body casing, where the inclination angle is within a detectable angle range of the sensor unit (150). According to such configuration, a compact and inexpensive pedometer in which lowering in measurement precision due to variation in the attachment state attributed to the body shape of the user is prevented is obtained.
