专利汇可以提供Electronic system module for crystal-controlled watch专利检索,专利查询,专利分析的服务。并且A replaceable module incorporating the electronic systems for a compact crystal-controlled watch wherein the high-frequency of a quartz crystal is scaled down to produce low-frequency pulses. These pulses actuate a time display by means of a tuning fork motor whose sole function is to turn the hands of the watch. The module is constituted by an oscillator circuit, the output of which is fed to a multi-stage frequency divider, the oscillator circuit and divider being embodied in a single package containing integrated circuitry. The module is joined to an incrementallyadjustable capacitor unit for tuning the oscillator circuit. Extending from the module are five terminal lugs and one connecting tab, the first two providing support for and connections to a quartz crystal assembly mounted below the tuning unit. The second and third lugs are connectable to a power cell, while the fifth lug which yields the system out-put pulses, is connectable to the tuning fork motor. The tab serves to connect the tuning unit to the oscillator circuit.,下面是Electronic system module for crystal-controlled watch专利的具体信息内容。
