    • A sensor has an emitting device for emitting radiation pulses repeatedly and a receiving device for receiving these pulses. The receiving device includes a converter such as a photoelectric converter to convert the received radiation pulses into electrical pulses. On the basis of a known waveform characteristic or characteristics of true electrical pulse it is judged if a pulse which appears on the output line of the converter is a true electrical pulse caused by receiving the radiation pulse emitted from the emitting device or a false electrical pulse caused by noise. The result of this judgment is outputted from an output device. The emitting device may serve to emit the pulses according to a specified bit pattern and the receiving device may serve to compare the pattern of received pulses with a standard bit pattern and to thereby distinguish between true and false electrical pulses.
    • 传感器具有用于重复发射辐射脉冲的发射装置和用于接收这些脉冲的接收装置。 接收装置包括诸如光电转换器的转换器,以将接收到的辐射脉冲转换成电脉冲。 基于已知的波形特性或真电脉冲的特性,判断出现在转换器的输出线上的脉冲是否是由接收从发射装置发射的辐射脉冲或假电脉冲引起的真电脉冲 造成噪音 该判断结果从输出装置输出。 发射装置可以用于根据指定的位模式发射脉冲,并且接收装置可以用于将接收的脉冲的模式与标准位模式进行比较,从而区分真假电脉冲。

    • A non-volatile semiconductor memory device includes a substrate and a continuously formed drain diffusion layer and a continuously formed source diffusion layer which are alternately arranged within the substrate. Floating gates are disposed via a tunnel insulating film on the substrate so that they are adjacent to the drain diffusion layer. The floating gates are opposed to each other with the drain diffusion layer therebetween, and spaced away from the source diffusion layer. A control gate extends in a direction orthogonal with a direction in which the source and drain diffusion layers extend, the control gate being formed on the floating gates and the substrate via an insulating film. A select channel is provided between the floating gate closest to the source diffusion layer and the source diffusion layer. A thick insulating film is provided between the drain diffusion layer and the control gate between the floating gates which are opposed to each other with the drain diffusion layer therebetween.
    • 非易失性半导体存储器件包括基板和连续形成的漏极扩散层和连续形成的源极扩散层,其交替地布置在基板内。 浮动栅极通过衬底上的隧道绝缘膜设置,使得它们与漏极扩散层相邻。 浮置栅极彼此相对,其间具有漏极扩散层,并且与源极扩散层间隔开。 控制栅极在与源极和漏极扩散层延伸的方向正交的方向上延伸,控制栅极通过绝缘膜形成在浮动栅极和衬底上。 在最靠近源极扩散层的浮置栅极和源极扩散层之间提供选择沟道。 在漏极扩散层和控制栅极之间的漏极扩散层之间彼此相对的浮置栅极之间设置厚的绝缘膜。
