Abstract: A polyester container furnished with a flange part having mechanical strength, transparency, and heat resistance through orientational crystallization, which polyester container exhibits low-temperature heat sealability, is provided by forming a projecting portion at an upper surface of the crystallized flange part, the projecting portion at at least a heat-sealing-face constituting region rendered amorphous or of low crystallinity. Further, in order to suppress the unevenness of the strength of sealing with a cover member and stably attain the high sealability, the projecting portion is deformed at the time of heat sealing with the cover member so as to form a resin piece protruding toward the interior of the container while being substantially appressed against the upper surface of an opening rim part. The formed resin piece couples with a sealant layer of the cover member.

Abstract: The present invention provides a redrawing method which comprises holding a preliminarily drawn cup of a covered metal sheet by an annular holding member inserted in the cup and a redrawing die, and relatively moving the redrawing die and a redrawing punch arranged coaxially with the holding member and redrawing cup, said drawing punch being capable of going into the holding member and coming out from the holding member, so that the redrawing die and redrawing punch are engaged with each other, to form a deep-drawn cup having a diameter smaller than that of the preliminarily drawn cup. This redrawing method is prominently characterized in that the radius of curvature of the operating corner portion of the redrawing die is 1 to 2.9 times as large as the bare sheet thickness of the metal sheet.

Abstract: A surface acoustic wave device comprises a piezoelectric substrate, and an input transducer and an output transducer formed on the substrate. Dummy transducers are formed on the substrate and arranged to extend from the ends of the input and output transducers toward the ends of the substrate. The dummy transducers individually include electrodes spaced at the same pitch as the electrode pitch in the input and output transducers. Accordingly, there is no occurrence of reflections of the surface acoustic wave at the ends of the input and output transducers.

Abstract: A surface acoustic wave device comprising a piezoelectric substrate, an input transducer and an output transducer arranged diagonally to each other. A multistrip coupler is interposed between the input and output transducers. A reflecting transducer is placed opposite to the input transducer with the multistrip coupler therebetween. The multistrip coupler includes an adjusted number of conductors. The reflecting transducer includes weighted electrodes, and means for adjusting phase difference, whereby the surface acoustic waves reflected by the output transducer and the reflecting transducer are cancelled by each other. Accordingly, triple transit echo (TTE) can be suppressed without use of external variable resistors and inductors.
