    • There is provided a positioning system which generates an appropriate response according to a positioning accuracy request class from a client device. A client device 101 specifies the positioning accuracy and the request class thereof that it requests to transmit a positioning request of a mobile station 103 to a server device 102. The server device 102 checks the positioning accuracy requested by the client device 101, and, if positioning results which satisfy the requested accuracy exist, responds the positioning results. If the positioning results which satisfy the requested accuracy do not exist, the server device 102 checks the accuracy request class, selects the positioning results with the highest positioning accuracy to respond to the client device 101 in the case of a second class (“Best Effort”), and notifies an error to the client device 101 in the case of a first class (“Assured”).
    • 提供了一种根据来自客户端设备的定位精度请求类产生适当响应的定位系统。 客户端装置101将请求发送移动台103的定位请求的定位精度及其请求等级规定给服务器装置102.服务器装置102检查由客户装置101请求的定位精度,如果 存在满足要求精度的定位结果,对定位结果做出响应。 如果不存在满足要求精度的定位结果,则服务器装置102检查精度请求等级,在第二级的情况下以最高定位精度选择定位结果来响应客户端装置101(“最佳努力” “),并且在第一类(”Assured“)的情况下向客户端设备101通知错误。

    • A buffer circuit is provided between a gate terminal of a pull-down transistor and a threshold circuit receiving a gate signal as an input signal. A voltage applied to an output terminal of a power semiconductor element from an external battery power supply is supplied to the buffer circuit through a resistive element. The buffer circuit converts the level of an on-signal output from the threshold circuit into a voltage higher than the threshold of the pull-down transistor, so that the pull-down transistor operates surely to turn off the power semiconductor element even when the level of the gate signal is low. Thus, there is provided a semiconductor integrated circuit device having a power semiconductor element which can be turned off by sure operation of a pull-down semiconductor element.
    • 在下拉晶体管的栅极端子和接收栅极信号的阈值电路之间设置缓冲电路作为输入信号。 从外部电池电源向功率半导体元件的输出端施加的电压通过电阻元件供给缓冲电路。 缓冲电路将来自阈值电路的导通信号输出的电平转换成高于下拉晶体管的阈值的电压,使得下拉晶体管可靠地工作以关闭功率半导体元件,即使当电平 的门信号为低电平。 因此,提供了具有功率半导体元件的半导体集成电路器件,该功率半导体元件可以通过下拉半导体元件的可靠操作而被关断。
