    • Of margins of a resin molding with an antenna element buried therein which lie around the antenna element, a margin on that side of the resin molding where a gate mark remains is made larger than margins on other sides where there is no gate mark. Particularly, when the antenna element has a line antenna portion and a capacitance-adding portion provided at a distal end of the line antenna portion, the resin molding is injection-molded in such a way that a gate mark can be formed on that side where the capacitance-adding portion is located. Those portions of the resin molding where the terminal portions are led out are dented from levels of portions around those portions. This provides a chip antenna which has a simple structure with a high mechanical strength and does not prevent separation or cracking from occurring in the resin molding in which the antenna element is buried and a method of manufacturing the chip antenna.
    • 在埋设在天线元件周围的天线元件的树脂模制品的边缘处,留下栅极标记的树脂模制品侧的边缘大于没有栅极标记的另一侧的边缘。 特别地,当天线元件具有线天线部分和设置在线天线部分的远端处的电容增加部分时,树脂模制件以这样的方式被注射成型,即可以在那一侧形成栅极标记 电容添加部分被定位。 端子部分被引出的树脂模塑件的那些部分由这些部分周围的部分的凹陷凹陷。 这提供了具有机械强度高的简单结构的芯片天线,并且不防止在埋设天线元件的树脂模制件中发生分离或破裂以及制造芯片天线的方法。

    • A molding method and a mold therefor capable of forming a doll head of a shape exactly conforming to a mold by blow molding using a safe molding material. A split mold (2, 3) which has an inner surface formed to have a configuration conforming to a shape of a doll head (17) is so arranged that a parting line (18) formed by mold members (2, 3) of the split mold may be formed on a hairline of the hair of the doll head (17) or in proximity thereto. A molding material is constituted by a thermoplastic synthetic resin elastomer as a main ingredient thereof and has a plasticizer and a coloring agent added thereto. The molding material is heated and then dropped in as a parison (15) between the mold members (2, 3) of the split mold spaced from each other. Then, the mold members (2, 3) of the split mold are joined together and air is blown into the split mold. Air is removed through at least one projection such as a nose (5) or the like from a cavity during blowing of air into the split mold (2, 3).
    • 一种成型方法及其模具,其能够通过使用安全模塑材料的吹塑成型而形成与模具完全一致的形状的玩偶头部。 具有形成为具有符合人体头部(17)的形状的构造的内表面的分割模具(2,3)被布置成使得由模具构件(2,3)形成的分型线(18) 分开模具可以形成在玩偶头部(17)的头发的发际线上或其附近。 成型材料由热塑性合成树脂弹性体作为其主要成分,并且添加有增塑剂和着色剂。 将成型材料加热,然后在分型模具的模具构件(2,3)之间作为型坯(15)落下,彼此间隔开。 然后,将分模的模具(2,3)接合在一起,并将空气吹入分模。 在将空气吹入分模(2,3)期间,空气通过诸如鼻(5)等的至少一个突起从空腔移除。
