This invention is a highly insulating film, which is characterized by including a biaxially stretched film containing a styrene polymer having a syndiotactic structure as a main component, containing a thermoplastic amorphous resin Y having a glass transition temperature Tg by DSC of 130 C. or higher in an amount of 5% by mass or more and 48% by mass or less, and having a plane orientation coefficient (AP) represented by the following equation (1) of 0.027 or less: P=(Nx+Ny)/2Nz (1). In equation (1), Nx represents the minimum value of the refractive index in the plane direction of the film, Ny represents the refractive index in the direction perpendicular to Nx in the plane direction of the film, and Nz represents the refractive index in the thickness direction of the film.

Novel extruded ceiling fan blades, compositions and methods of making the blades from plastic material such as polystyrene are disclosed. The blades can be formed from two extruders so that different colors and/or finishes, such as wood grain looks can be formed on the upper and lower surfaces of the blades.

Materials for use in 3D printing comprising a color shift pigment that change colors when viewed at different angles. More specifically, the materials comprise a color shift pigment being a silicon oxide core with metal oxide shell disposed thereon and a polymeric component.

Systems and methods for joining blade components of a rotor blade are provided. A method includes positioning a first blade component and a second blade component such that a joint location of the first blade component and a joint location of the second blade component are proximate each other. The method further includes applying a force to an outer surface of the second blade component and an opposing force to an inner surface of the second blade component. The force and opposing force maintain an aerodynamic contour of the second blade component. The method further includes connecting the joint location of the first blade component and the joint location of the second blade component together.

A method of sealing a container and a lid by melt adhesion by laser. Either the container or the lid has a thermoplastic resin that permits the laser beam to transmit through and the other one has a resin composition of the thermoplastic resin containing a heat-generating substance. Further, the laser beam applies a rectangular beam having a uniform intensity distribution. The upper-limit of temperature is not lower than a melting point of the thermoplastic resin but lower than a thermal decomposition start temperature thereof in the melt adhesion interface between the container and the lid, and the temperature reaches the upper-limit in a heating time t (msec) represented by the following formula (1),

A wave guide face plate for transmitting an image formed in a scintillating material included as part of a transmitting medium is disclosed. The transmitting medium includes a random distribution of different refractive index regions in two orthogonal dimensions, and an essentially consistent refractive index in a third orthogonal dimension. The third orthogonal direction is aligned with a transmission axis of the wave transmitter extending from an input location to a wave detector location. The transmission efficiency of the wave guide faceplate is improved in situations where the entry angle of the input radiation is different from the axis of the wave transmitter as compared to conventional faceplates.
