    • Communication equipment that is provided with an isolating switch, which is operated by placement of a handset, instead of a conventionally used insulating component. The isolating switch constitutes an electrical insulation between a charging, terminal of a base unit and an external electric circuit. This structure eliminates the necessity of providing an insulating component such as a transformer and the like, so as to achieve a cost reduction of the communication equipment, and also improves sound quality of the communication equipment. In addition, the isolating switch is arranged in Such a manner that a direction of tile force applied by the handset to depress the terminal of the base unit and a direction of the force applied by the handset to depress a switch level are separated from each other. The isolating switch has a construction that enables the switch lever to function with a small loading weight, and to keep a contact point of the switch depressed by an intense force. As a result, reliable operation of the switch is attained without increasing, the weight of the handset, since the is available weight of the handset can be utilized efficiently. Further, a mechanical structure for fixing the position of the handset can be eliminated, so as to simplify the overall structure of the communication equipment.
    • 具有隔离开关的通信设备,其通过放置手机而不是常规使用的绝缘部件来操作。 隔离开关构成基本单元的充电端子和外部电路之间的电绝缘。 这种结构消除了提供诸如变压器等的绝缘部件的必要性,以便实现通信设备的成本降低,并且还提高通信设备的声音质量。 此外,隔离开关被布置成使得由手持机施加的按压基座的端子的方向的方向和由手机施加的按压开关水平的力的方向彼此分离 。 隔离开关具有使得开关杆能够以小的负载重量工作并且通过强力保持开关的接触点的结构。 结果,可以在不增加的情况下实现开关的可靠操作,因为可以有效地利用手机的重量,因为手机的可用重量。 此外,可以消除用于固定手机位置的机械结构,从而简化通信设备的整体结构。

    • The present invention provides an image display apparatus equipped with a common terminal section 10 to which a single-density signal and a double-density signal each having different horizontal scanning frequencies to each other are commonly connected. The single-density and double-density signals are selectively inputted to the single-density signal processing circuit 5 or the double-density signal processing circuit 6 by a switching operation of a switch 11. A synch-signal separation circuit 13 separates a synchronous signal carrying the horizontal scanning frequency from the signal inputted to the common terminal section 10. An fV-conversion circuit 14 converts a horizontal scanning frequency of the synchronous signal into a voltage. A frequency discrimination circuit 15 detects the horizontal scanning frequency and memorize it in a look-up table of a memory device 16. A control circuit 17 controls switching operations of the switches 7, 11 on the basis of the horizontal scanning frequencies of the signals memorized in the look-up table of the memory device 16.

    • Piezoelectric crystalline film of zinc oxide with a hexagonal crystal structure and a c-axis substantially perpendicular to the film surface, the crystalline film containing, as additive elements, vanadium and manganese together with or without copper. The piezoelectric crystalline films have high resistivity and a smooth surface, and make it possible to produce piezoelectric transducers with good conversion efficiency which can be used in a wide range of low to high frequencies. Such films can be made by a method comprising sputtering source materials, i.e., zinc oxide, vanadium and manganese together with or without copper onto a surface of a substrate to form a crystalline zinc oxide film, the sputtering being effected by using a film material source consisting essentially of a ceramic of zinc oxide containing vanadium, and manganese together with or without copper.
