摘要:
A composite spout which does not permit a sleeve fitted onto the core to be deviated during the injection forming and does not permit end surfaces of the sleeve to be exposed in the spout body. A spout body is injection-formed in a state where a sleeve having a functional resin layer disposed as an intermediate layer is fitted as a core onto the core member of an injection-forming metal mold such that the inner peripheral surface only of the sleeve is substantially exposed on the inner peripheral surface of the spout body. A tilted surface is formed on the inner peripheral surface at one end of the spout body in at least a portion thereof in the circumferential direction, the tilted surface being tilted outward in the radial direction from a position in agreement with the inner peripheral edge at the one end of the sleeve or from the inside thereof in the radial direction facing the one end of the spout body.

A cap having biodegrading property comprising a cap shell including a top panel and a skirt portion, and a liner member applied to the inner surface of the top panel of the cap shell, wherein the cap shell is made of a resin composition of a hard aliphatic polyester resin (A) and a soft aliphatic polyester resin (B) which are blended at a weight ratio of A:B=20:80 to 80:20, and the liner member has biodegrading property. A container with cap is provided effectively preventing the generation of resin powder at the time of the opening/closing operation even when the cap is used for a container made of a rigid biodegradable resin such as of polylactic acid, exhibiting excellent sealing and formability. Besides, the packing container as a whole features biodegrading property and is environmentally friendly.

Electromagnetic noise absorbing material and filter, which are small, light, and effective even with respect to unwanted electromagnetic waves of a few hundred MHz or more, are provided. A small and flexible electromagnetic noise filter cable and tape-shaped electromagnetic noise filter, as well as a manufacturing method and manufacturing apparatus therefor, are also provided. The electromagnetic noise absorbing material has a thickness or particle diameter of the alloy magnetic substance which is within a range of from 1/10 to 10 times the skin depth thereof, and thereby, a large eddy current loss can be generated, so that it is possible to manufacture electromagnetic noise filters having various shapes, which are small, light, and which realize a large electromagnetic noise suppression effect as a result of eddy current loss, and these possess a large relative magnetic permeability even at levels of a few hundred MHz or more. According to the thin film manufacturing method and apparatus, it is possible to easily manufacture an electromagnetic noise absorbing material having small hysteresis, possessing a hard axis of uni-axial magnetic anisotropy, which is superior in high-frequency response, and has a large electromagnetic noise suppression effect.

A plastic cap having a peripheral band 4 which is provided at the lower end of the skirt-like side wall portion of the cap body, wherein the lower end of the skirt-like side wall portion outwardly protrudes, the peripheral band 4 downwardly extends from the protruded portion 10 at the lower end via a breaking line 11 that is circumferentially formed leaving a plurality of bridges 12, a downwardly extending stopper piece 20 is disposed on the side of closing the cap with respect to at least one of the bridges 12, the stopper piece 20 comes into contact with the bridge 12 at the time of closing the cap, and the cap body and the peripheral band 4 turn together. There is no need of providing space for forming stoppers between the lower end of the skirt-like side wall and the upper end of the peripheral band portion. Therefore, the coupling portion between the two is easily formed by providing a breaking line in the subsequent working of cutting. The cap is integrally molded without the need of using a metal mold having complex surface shapes or a split mold, and the rate of production can be enhanced.

In a resonator which has an ultrathin vibratory portion formed integrally with a thick frame-like rib surrounding it, a pair of opposed thick marginal portions of the frame-like rib are formed so that their widths gradually decreases toward another marginal portion of the rib from the other remaining one perpendicular to the above-noted pair of opposed marginal portions and to be fixed to a resonator case. This structure substantially increases the mechanical strength of the piezoelectric resonator, even if it is held in a cantilever fashion, and protects it from breakage by an external vibration or shock.

.gamma.-Fe.sub.2 O.sub.3 film added at least one selected from the group consisting of Pd, Au, Pt, Rh, Ag, Ru, Ir, Os as additive, especially Os are disclosed. Reduction from .alpha.-Fe.sub.2 O.sub.3 to Fe.sub.3 O.sub.4 is accelerated by additive Os to accompany to a uniform reduction and increased the ratio of magnetic phase in the film. .gamma.-Fe.sub.2 O.sub.3 film medium added Os improves the saturation magnetization and increases the coercive force in proportion to amount of additive Os. Application of an external field to said film introduced magnetic anisotropy into said film, therefore said film medium improves coercive force and squareness of hysteresis loop by the grant of anisotropy. .gamma.-Fe.sub.2 O.sub.3 crystal grain is prepared by additive Os to obtained fine grain. The resultant .gamma.-Fe.sub.2 O.sub.3 film medium decreases the noise.
