    • An improved tape cassette (2) includes a case (4) having an open front end (14) to which a door (16) is pivotally mounted for movement between open and closed positions. The door is a molded plastic part and preferably includes an integrally molded plastic spring (32). The spring is positioned, shaped and sized so that its outer end (34) engages the case to bias the door from the open position to the closed position. The spring is preferably made of a spring quality plastic while the rest of the door is made of a structural quality plastic. This permits the spring to have the desired resilient qualities while the rest of the door can have appropriate structural properties.
    • 改进的带盒(2)包括具有敞开的前端(14)的壳体(4),门(16)枢转地安装在该开口前端(14)上,用于在打开和关闭位置之间移动。 门是模制塑料部件,并且优选地包括一体模制的塑料弹簧(32)。 弹簧的定位,形状和尺寸使得其外端(34)接合壳体以将门从打开位置偏压到关闭位置。 弹簧优选地由弹簧质量塑料制成,而门的其余部分由结构质量塑料制成。 这允许弹簧具有期望的弹性质量,而门的其余部分可以具有适当的结构特性。

    • A telephone answering device (TAD) records incoming messages and notifies a party at a forwarding telephone number when a predetermined number of such incoming messages have been received. The TAD may include remote operation features, allowing a party so notified to play back, store or erase messages received by the TAD, for example. Notification and remote operation may be protected by a security feature, whereby these functions are discontinued if a correct access code is not received. Commands and access codes may be received by the TAD in the form of dual-tone, multi-frequency signals, such as are commonly used to transmit dialing information from a telephone instrument to telephone switching gear.
    • 当接收到预定数量的这样的传入消息时,电话应答设备(TAD)记录传入消息并且以转发电话号码通知一方。 TAD可以包括远程操作特征,例如允许如此通知的一方回放,存储或擦除由TAD接收的消息。 通知和远程操作可能受到安全功能的保护,如果未接收到正确的访问代码,则这些功能将被停止。 TAD可以以双音多频信号的形式接收命令和接入码,例如通常用于将拨号信息从电话乐器传送到电话切换装置。
