    • A photosensitive member for use in an electrophotographic apparatus in which a bias potential is applied to the member during development. The member comprises a conductive support having at least one support edge and a photosensitive layer formed on the surface of the support and extending up to a point substantially coincident with the support edge. A tapered surface is formed at the extremity of the photosensitive layer adjacent to each support edge which extends from the top of the photosensitive layer to the support edge. The maximum angle between a tangent of the tapered surface and the surface of the conductive support is less then 45.degree. thereby preventing an edge effect by which a background smearing in the form of a black band may appear on copied paper obtained. Such a tapered surface can be easily formed through a vaporizing technique with a special masking in accordance with the present invention.
    • 一种用于电子照相设备的感光构件,其中在显影期间将偏置电位施加到构件。 该构件包括具有至少一个支撑边缘和形成在支撑件表面上的感光层并且延伸到与支撑边缘基本一致的点的导电支撑件。 锥形表面形成在感光层的与感光层的顶部延伸到支撑边缘的每个支撑边缘相邻的末端处。 锥形表面的切线与导电支架的表面之间的最大角度小于45°,从而防止了在获得的复印纸上可能出现黑带形式的背景污迹的边缘效果。 根据本发明,通过具有特殊掩模的汽化技术可以容易地形成这种锥形表面。

    • A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (10A) with a first transmitter (40A) for transmitting a first data indicative of a specific event, and a second radio terminal (40A) with a battery (14B) and a receiver (20B). The first radio terminal (10A) includes a first bit interpolator (32A) which inserts a check bit pattern of “01010101” at a predetermined cycle into one frame of the first data. The second radio terminal (10B) has a second power controller (60B) which intermittently activates the second receiver (20B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter. A check bit detector (24B) is included in the second radio terminal (10B) to detect the check bit pattern from within the bit interpolated data and to issue a stop signal immediately upon occurrence of that the check bit pattern fails to appear at said predetermined cycle within a predetermined time frame shorter than one frame length of the first data. In response to the stop signal, the power controller of the second radio terminal terminates a current receiving operation.
    • 无线电通信系统最小化对噪声的功耗。 该系统包括具有用于发送指示特定事件的第一数据的第一发射机(40A)和具有电池(14B)和接收机(20B)的第二无线电终端(40A)的第一无线电终端(10A)。 第一无线电终端(10A)包括第一比特内插器(32A),其将预定周期的01010101的校验比特模式插入到第一数据的一帧中。 第二无线电终端(10B)具有以预定间隔间歇地激活第二接收机(20B)的第二功率控制器(60B),以便从第一发射机接收位插值数据。 检查位检测器(24B)包括在第二无线电终端(10B)中,以从位内插数据内检测校验位模式,并且在发生校验位模式不能出现在所述预定位置时立即发出停止信号 在比第一数据的一帧长度短的预定时间范围内循环。 响应于停止信号,第二无线电终端的功率控制器终止当前接收操作。

    • A magnetic read head having a novel magnetic bias structure that provides improved magnetic biasing for improved free layer robustness and reduced Barkhausen noise. The bias structure includes hard magnetic layer formed over first and second under-layers. At least a portion of the first under-layer is formed as discrete islands of material, and the second under-layer is formed over the first under-layer. The first under-layer has a thickness of 0.25 to 0.75 nm. The novel seed layer structure causes hard magnetic layer to have a magnetic anisotropy that is substantially parallel with the free layer of the sensor stack even in regions adjacent to the sensor stack.
    • 具有新的磁偏置结构的磁读头,其提供改进的磁偏置,以改善自由层鲁棒性和降低的巴克豪森噪声。 偏置结构包括在第一和第二下层上形成的硬磁性层。 第一底层的至少一部分形成为离散的材料岛,并且第二底层形成在第一底层之上。 第一底层具有0.25至0.75nm的厚度。 新颖的种子层结构使得硬磁性层具有磁性各向异性,即使在与传感器堆叠相邻的区域中,磁各向异性基本上与传感器堆叠的自由层平行。
