Abstract: In a cellular phone terminal, a bit error rate measurement section measures a bit error rate of broadcast data received by a broadcast reception section for receiving a digital broadcast to output broadcast data while a transmission operation of a communication transmission section for wirelessly communicating with a broadcasting communication network is performed. When the measured bit error rate is equal to or higher than a predetermined threshold, stopping of the transmission operation of the communication transmission section is instructed. Thus, a failure such as interruption of television broadcasting reproduction can preliminarily be prevented by avoiding error occurrence in reception of the 1 segment broadcasting service due to an influence of a transmission electric wave in data communication. As a result, stable reception of the 1 segment broadcasting service can be executed.

Abstract: A lay-flat device of a blown film extrusion installation includes brush rollers in the upper half entirely or partly. The brush rollers include bristles which are directed obliquely outwards and which, on contact with an extruded film tube, exert a slight spreading force on the film, by which folding is avoided.

Abstract: In an apparatus and method for measuring retardance and slow axis azimuth in sample specimens, a sample is illuminated by circularly polarized monochromatic light which is then analyzed by an elliptical analyzer at different settings. In another embodiment, light conditioned by an elliptical polarizer at various settings illuminates a specimen and the beam exiting the sample is analyzed by a circular analyzer. The elliptical analyzer/polarizer may have selectable ellipticity and azimuth angle, including in some cases a setting of circular polarization. Background images obtained with selected settings of the elliptical analyzer/polarizer, but without the sample present, are used in some embodiments to improve the measurement.
