A container lid is composed of a synthetic resin inside plug to be mounted on the mouth of a container, and a synthetic resin lid to be mounted on the inside plug. A breakable thin-walled line formed in a closing wall has an outer arcuate portion extending from a breakage start end portion, and an inner arcuate portion extending from the breakage start end portion, and defines an arcuate deformation region. A locked element is annexed to the deformation region, and a locking element is in the lid. When the lid is rotated in a predetermined direction, the locking element is locked to the locked element. When the lid is rotated further in the predetermined direction, a force is exerted on the deformation region via the locking element and the locked element, so that the breakable thin-walled line of the inside plug is broken and the deformation region is deformed.

Non-contact type data carrier

Provided is a non-contact communication device including an antenna configured to transmit data through non-contact communication after load-modulation of an RF signal from a reader/writer (R/W), wherein the antenna includes: a standard coil having an aperture with a predetermined size; and a small coil having an aperture with a size smaller than a size of the standard coil, wherein the standard coil and the small coil are connected in series or in parallel, and the small coil is arranged such that the aperture of the small coil overlaps a winding part of a coil that is an antenna of the R/W when the non-contact communication device is caused to face the R/W by matching a predetermined position of the non-contact communication device with a reference position of the R/W determined in advance as a position with which the predetermined position of the non-contact communication device is to be matched.

[Problems to be Solved] In a synthetic resin container closure of a type which includes a body and a tamper evident bottom portion connected to the body via a plurality of breakable bridge portions arranged with spacing in a circumferential direction, and in which the body continues to be connected via unbroken connecting pieces to the tamper evident bottom portion continuously mounted on a mouth-and-neck portion of a container even after the bridge portions are broken to remove the body from the mouth-and-neck portion of the container, an improvement is made so that the container closure can be applied, without posing problems, even when the ascent distance of the body when removed is relatively long. [Means to Solve the Problems] Each of the unbroken connecting pieces is in such a form as to include two tilting portions whose tilting directions are opposite to each other.

A composite spout obtained by injection forming a spout body 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 method for making a combination IC card comprising the steps of forming antenna leads and patterned connection leads, forming a hole for mounting an external electrode chip on a sheath on at least one side of the antenna substrate, mounting an IC chip on the antenna substrate having the antenna leads and the patterned connection leads, mounting the external electrode chip on the antenna substrate having the antenna leads and the patterned connection leads, and attaching the sheath having the hole on the antenna substrate.

Method for making IC card

An IC card having high reliability, which is not only in that printing can be surely conducted with respect to the reversible display layer provided on the surface of the card substrate, but also in that the IC chip is surely protected by the reinforcing sheet. An IC card which has: an IC module () including an IC chip () mounted on an insulating substrate (), and a reinforcing sheet () provided over the IC chip () through a sealing resin () for sealing the IC chip (); a card substrate () comprised of a resin for sealing the IC module (); and a reversible recording layer () provided on at least one surface of the card substrate (), wherein reinforcing film patterns (), (') having openings (), (&#x2032;) which expose the IC chip () mounted portion are provided on at least one of the IC chip () mounted surface and the non-mounted surface of the insulating substrate ().

The present invention relates to an electronic device that suppresses reduction in reception sensitivity and occurrence of distortion when IC cards are used while stacked. A loop antenna equipped on the IC card has up to four turns, and is designed so that one turn, for example, has a first linear portion, a first curved line portion, a second linear portion, and a second curved line portion. When two electronic devices having a first loop antenna and a second loop antenna, respectively, are stacked onto one another, the corners of the loop antennas do not overlap. For example, the corner formed by first curved line portion and the second linear portion of the first loop antenna is overlapped with the first curved line portion of the second loop antenna. The first and second loop antennas are shaped such that when two electronic devices are stacked, their respective loop antennas are superimposed in the opposite direction so that the corners are not overlapped and the amount of overlap as a whole is reduced. The present invention may be applied to an IC card for receiving/transmitting data under non-contact state.

Noncontact type IC card

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 powder beam etching machine, slopes are formed in upper and lower edge surfaces of a rib formed along an outer margin of a platen and through-holes are formed around four corners. With such an arrangement, the powders adhered work may readily be removed by injection of air during a cleaning operation.

A method for preparing ultrathin piezoelectric resonator plates having an ultrathin vibrating portion enclosed by a thick periphery portion, comprising a forming process which forms a plurality of depressions in one side of a wafer of a piezoelectric material to form ultrathin vibrating portions as the bottom wall of each depression and a trimming process which trims the thickness of each vibrating portion by etching to adjust the resonance frequency, characterized by bonding a comparatively thick plate with a plurality of holes formed at the positions corresponding to the depressions in the wafer to the depressed side of the wafer or forming a layer with a plurality of holes formed at the positions corresponding to the depressions in the wafer over the depressed side of the wafer, and putting an etching liquid into the depressions through the holes in the thick plate or layer. By this method, excessive or incomplete trimming in the trimming process can be prevented and hence the yield rate of product increases.
