Abstract: Supporting force for an information display panel is increased to reduce troubles such as displacement and removal of the panel, and attachment and detachment of the information display panel are facilitated. An electronic shelf label (1) includes an electronic shelf label body (2) having a liquid crystal panel (21), and a shelf label frame (3) for housing the electronic shelf label body (2). The shelf label frame (3) includes a frame-like portion (32), which is arranged on a display portion surface side and has a window for an electronic display portion formed therein, and a pair of opposing guide rails (33A and 33B), which are provided on a surface of the frame-like portion (32) and are capable of holding a window frame display panel (4) capable of displaying arbitrary information with the window frame display panel (4) inserted thereinto from above the display portion surface.

Abstract: According to the present invention, in the PFC (planar flow casting) method, He gas at room temperature is blown onto the surface of a cooling roll at a flow rate of 0.1 to 5 liters/min.multidot.cm.sup.2 through a He gas blow nozzle provided upstream of a molten alloy (a puddle) ejected through a molten alloy ejection nozzle onto the surface of the cooling roll at a distance from the ejection nozzle, the distance from the surface of the cooling roll and an angle of inclination of the nozzle within respectively specified ranges, thereby forming a He gas atmosphere around the puddle, and a thin strip is dragged out of said puddle. This enables a thin amorphous alloy strip having a very small thickness and a smooth surface free from significant uneven portions and pores to be easily produced at a low cost without use of any vessel for regulating the atmosphere or an apparatus for heating the blown gas.
