    • Printed wiring boards (PWBs) applied to this inspection system are previously formed with marks in prescribed positional relation to wiring patterns. Deviation of PWBs with respect to absolute coordinates of the inspection system is detected by reading the marks. The PWBs are sequentially set one by one on a movable table, to be subjected to image acquisition of the marks and inspected areas. A first PWB is image-acquisited whereby obtained binary image data of the inspected area are stored in a memory unit. Thereafter a second PWB is image-acquisited, and in advance to the image acquisition of its inspected area, relative misregistration of the both PWBs is found by deviation data on respective marks of the first and second PWBs. The binary image data of the first PWB is read from the memory unit on the basis of the binary image data of the second PWB. When the binary image data of the first PWB are read, positional correction, i.e., time base correction is performed on the read data to correspond to pixels of the second PWB under image acquisition on the basis of data on the previously found amount of relative misregistration. The data on corresponding pixels of the both PWBs are compared with each other thereby to inspect difference between the patterns of the PWBs on the basis of the result of the comparison.
    • 应用于该检查系统的印刷电路板(PWB)预先用与布线图案规定的位置关系的标记形成。 通过读取标记来检测PWB相对于检查系统的绝对坐标的偏差。 PWB在可移动台上依次依次设置,对标记和检查区域进行图像采集。 第一PWB被图像采集,由此获得的被检查区域的二进制图像数据被存储在存储单元中。 此后,第二PWB被图像采集,并且预先对其检查区域进行图像采集,通过第一和第二PWB的相应标记上的偏差数据,发现两个PWB的相对重合。 基于第二PWB的二进制图像数据,从存储器单元读取第一PWB的二进制图像数据。 当读取第一PWB的二进制图像数据时,基于关于先前发现的相对重合的数量的数据,对读取的数据执行位置校正,即对于与图像采集期间的第二PWB的像素对应的时基校正 。 将两个PWB的对应像素的数据进行比较,从而根据比较结果来检查PWB的图案之间的差异。

    • A transmission power control method in a mobile satellite communication system implementing accurate control of transmission power of a base station by obtaining an average received signal level at a mobile station at high accuracy. The mobile station measures an average received signal level Q.sub.k in a predetermined period (step SP2), and informs the base station of the average received signal level Q.sub.k and an actual measuring time T.sub.k (step SP3). The base station calculates a total measuring time t.sub.k which is the sum total of the actual measuring time T.sub.k (step SP16), a corrected average received signal level R.sub.k associated with the average received signal level during the total measuring time t.sub.k (step SP18), and a measuring error .DELTA.D.sub.k (step SP17), and controls the transmission power on the basis of these values (step SP21). Estimating the measuring error .DELTA.D.sub.k in the total measuring time t.sub.k longer than the individual actual measuring time T.sub.k makes it possible to reduce the measuring error, thereby implementing highly accurate transmission power control.
    • 一种移动卫星通信系统中的发送功率控制方法,其通过以高精度获得移动站的平均接收信号电平来实现基站的发送功率的精确控制。 移动台在规定时间内测量平均接收信号电平Qk(步骤SP2),向基站通知平均接收信号电平Qk和实际测量时间Tk(步骤SP3)。 基站计算作为实际测量时间T k(步骤SP16)的总和的总测量时间tk,与总测量时间tk期间的平均接收信号电平相关联的校正平均接收信号电平Rk(步骤SP18) 和测量误差DELTA Dk(步骤SP17),并根据这些值控制发送功率(步骤SP21)。 在总测量时间tk中估计测量误差DELTA Dk比单个实际测量时间Tk长,可以减少测量误差,从而实现高精度的发射功率控制。

    • Disclosed herein is an image pickup apparatus for a printed wiring board comprising a solid state image sensor whose light receiving surface is set to be opposed to the surface of the printed wiring board, a main illumination source arranged to satisfy the law of regular reflection on the surface of the printed wiring board with respect to the light receiving surface of the solid state image sensor and a subsidiary illumination source arranged not to satisfy the law of regular reflection with respect to the light receiving surface of the solid state image sensor thereby to supply the light receiving surface with scattering light by strias formed on copper patterns. The amount of regularly reflected light, which is changed depending on the strias formed on the copper patterns, is substantially compensated by the scattering light, so that the amounts of light received by the solid state image sensor relating to the copper patterns are made substantially constant regardless of the radiation pattern of the strias. In addition, the main and subsidiary illumination sources are formed by light emitting diodes thereby to attain technical and economical advantages.
