    • Provided is a system event logging system for recoding a log of system events which relate to a process being monitored, the logging system having the aim of selectively recording system events that are necessary for purposes such as the reproduction of operations and excluding system events that are outside the intended purpose. Flag conditions and flag operation instructions are provided for each of the filters in a filter list, and the system event logging system uses the flag conditions as the conditions for applying the filters. When applying the filters, the logging system operates the flags according to the flag operation instructions. Thus, interrelated operation between the filters can be achieved by means of the flags, and also, interrelated operation can be achieved by means of the flags even between the processes performed for the system events.
    • 提供了一种系统事件记录系统,用于重新编码与所监视的进程相关的系统事件的日志,记录系统的目的是选择性地记录为诸如操作的再现所必需的系统事件,并且排除系统事件 超出预定目的。 为过滤器列表中的每个过滤器提供标志条件和标志操作指令,系统事件记录系统使用标志条件作为应用过滤器的条件。 应用过滤器时,记录系统根据标志操作指令操作标志。 因此,可以通过标志来实现滤波器之间的相互关联的操作,并且即使在为系统事件执行的处理之间也可以通过标志来实现相互关联的操作。

    • The invention discloses a single cone earth boring bit which is adapted to be used for boring in oil fields, mining and geological prospecting. The single cone earth boring bit is composed of a bit body (1), gauge blocks (2), active cutting gauge teeth (4), passive gauge teeth (3) and knobby cone (6) etc. On the knobby cone (6), there are inserted wear-resistant teeth intermittently or successively, so as to make the wear resistance of the bit cutting system to be matched with the service life of the bearing. At the same time, gauge blocks (2) are provided on the bit body which may be directly made on or welded to the bit body. On the gauge blocks (2), there are inserted common carbide or wear-resistant active cutting gauge teeth (4) and the passive gauge teeth (3) to enhance the gauge-protecting effect of the bit. Such a single cone earth boring bit can significantly increase the footage of the bit and reduce the cost for drilling.
    • 本发明公开了一种适用于油田镗孔,采矿和地质勘查的单锥钻地钻。 单个锥形钻头由钻头体(1),量块(2),有效切割表齿(4),被动测量齿(3)和旋钮锥(6)等构成。在圆锥体(6) ),间歇或连续地插入耐磨齿,以使钻头切削系统的耐磨性与轴承的使用寿命相匹配。 同时,钻头体上设置有可以直接制成或焊接在钻头体上的钻头块(2)。 在仪表块(2)上,插入普通碳化物或耐磨有源切割表齿(4)和被动测齿(3),以增强钻头的防护等级。 这种单锥钻地钻可显着增加钻头的镜头,并降低钻孔成本。
