摘要:
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.

The invention provides a stick-shaped cosmetic screw-out container including a holding cylinder fitting and holding a stick-shaped cosmetic and having a screwing projection provided from a side wall. The container also includes a shell cylinder including the holding cylinder vertically slidably, having a guide groove through which the screwing projection penetrates provided on a side wall and having an engagement concave portion provided on a lower side wall. The container further includes a sleeve fitted in the shell cylinder, having a screwing groove for screwing the screwing projection provided on an inner wall and having, on a lower inner wall, an inner peripheral rib engaged rotatably with the engagement concave portion so as not to be dropped out, a body cylinder for holding a lower portion of the shell cylinder so as not to be dropped out, and a fitting cylinder fixed onto the body cylinder and provided with a fitting portion in which a cap is removably fitted. The container is made such that at least one of the holding cylinder, the shell cylinder and the sleeve is formed of a different material. The lower portion of the shell cylinder is connected to the body cylinder unrotatably and removably so as not to be dropped out. The shell cylinder is divided into an upper shell cylinder and a lower shell cylinder. The upper shell cylinder is provided with the guide groove. A diameter increasing portion having an outside diameter increased is provided in a lower portion. A pair of window portions are provided in the vicinity of a lower end in a horizontal direction and a tongue piece-shaped inserting portion to enter from the lower end of the upper shell cylinder is linked to the lower shell cylinder. A hook is protruded from the window portion to an outside over a side wall of a tip portion of the inserting portion, and one of end faces of the hook is cut like a taper to constitute a cam portion, and in such a state that the hook is protruded from the window portion of the upper shell cylinder. The engagement concave portion is formed under the hook, and the hook is retracted into the window portion by the cam portion of the hook and is disengaged from the engagement concave portion when the upper shell cylinder and the lower shell cylinder are rotated relatively in a direction of the cam portion.

A slide type cosmetic stick vessel has a middle saucer for holding a cosmetic stick, which has an engaging projection formed on the outer wall thereof, a body cylinder having a longitudinal guide groove through which the engaging projection slides, a threaded cylinder fitted on the periphery of the body cylinder, the threaded cylinder having a right-hand flight groove with which the engaging projection is engaged, a cover cylinder in which the threaded cylinder is inserted and secured, the cover cylinder having a second engaging projection formed on the outer wall of the lower portion thereof, a middle cylinder having a left-hand flight groove with which the second engaging projection is engaged, the left-hand flight groove being formed on the inner circumferential wall of the lower portion of the middle cylinder, and a longitudinal engaging groove formed on the wall of the middle cylinder, a slide cylinder secured to the outer wall of the lower end of the body cylinder and having a rotation-stopping piece formed on the outer wall thereof, and a bottomed outer cylinder in which the middle cylinder is inserted and secured, wherein the middle saucer and the slide cylinder are slidable in the longitudinal direction.
摘要:
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.
摘要:
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.
