    • A primary deterioration diagnosis of a front catalyst (8) is performed based on the air-fuel ratio of the exhaust gas downstream of the front catalyst (8) detected in a first period each time the first period elapses when the engine (1) is running in a diagnosis region. A secondary deterioration diagnosis of the front catalyst (8) is performed based on the air-fuel ratio of the exhaust gas downstream of the front catalyst (8) detected in a second period longer than the first period each time the second period elapses when the engine (1) is running in the diagnosis region. When SOx discharge control is performed, primary diagnosis and secondary diagnosis are prohibited, and if it is determined in the primary diagnosis that the front catalyst (8) has deteriorated, SOx discharge control is prohibited to provide an opportunity for secondary diagnosis. In this way, the deterioration diagnosis of the front catalyst (8) can be precisely performed even if there are few opportunities for diagnosis due to lean air-fuel ratio running or SOx discharge control.

    • A joint torque detection system having a plurality of post-like members disposed around an axis of a joint which connects two links. The plurality of post-like members deform or twist when a torque is imparted to one of the links. An electric motor is fixed at one of the links and the motor rotation is reduced by a harmonic-drive speed reducer fixed at the other of the links. The plurality of post-like members are annularly disposed around the joint axis such that they embrace the speed reducer. A gap sensor (displacement detector) is fixed to the second link, close to the speed reducer between the output of the speed reducer and the second link in such a manner that the sensor generates a signal indicative of relative displacement of the speed reducer output (connected to the one of the links) and the second link. With this arrangement, the system can be incorporated in a small link mechanism such as a robot finger link mechanism, with excellent detection accuracy and an elongated service life.
    • 一种联合扭矩检测系统,其具有围绕连接两个连杆的接头的轴线设置的多个柱状部件。 当将扭矩赋予链接中的一个时,多个柱状部件变形或扭转。 一个电动机固定在一个链节上,并且通过固定在另一个连杆上的谐波驱动减速器来减小电动机的旋转。 多个柱状构件围绕接头轴线环形设置,使得它们包围减速器。 间隙传感器(位移检测器)被固定到第二连杆,靠近减速器的输出端与第二连杆之间的减速器,使得传感器产生指示减速器输出的相对位移的信号( 连接到一个链接)和第二个链接。 利用这种结构,该系统可以结合在诸如机器人手指连杆机构的小型连杆机构中,具有优异的检测精度和更长的使用寿命。

    • A tactile sensor device for detecting a state of contact with a workpiece has a base body and a contact member spaced from the base body by a gap, for contacting the workpiece. The contact member is supported on the base body by a thin leaf spring for angular movement with respect to the base body and/or movement across the gap to cause a change in a distance between the contact member and the base body across the gap when the contact member is contacted by the workpiece. A gap sensor is mounted in the base body for generating a signal depending on the distance between the contact member and the base body across the gap at a predetermined region. A state of contact between the contact member and the workpiece can be detected on the basis of the distance across the gap as detected by the signal generated by the gap sensor.

    • A dynamic channel allocation process successively allocates channels of higher priorities to requests for channel allocation. When a priority change count overflows or reaches an upper limit, the priority change count is cleared to zero. However, past data are not eliminated, and a change in a base station service area can be handled. Specifically, when the priority change count reaches an upper limit n, the priority at that time is stored as M.sub.1, and fixed as it is until the priority change count reaches the upper limit n next time. When priority change count reaches the upper limit n twice, the priority at that time is updated to M.sub.2 and stored fixedly for use as the priority until the priority change count subsequently reaches the upper limit n.
    • 动态信道分配过程连续地将更高优先级的信道分配给信道分配请求。 当优先级更改计数溢出或达到上限时,优先级更改计数清零。 然而,过去的数据不被消除,并且可以处理基站服务区域的改变。 具体地说,当优先级改变计数达到上限值n时,此时的优先级被存储为M1,并且直到固定,直到优先级改变计数到达下一次的上限值为止。 当优先级更改计数达到上限值n时,将此时的优先级更新为M2,并固定存储,作为优先级,直到优先级变更计数随后达到上限值n为止。

    • In a dynamic channel allocation system, upon every communication request, selection is made of a channel having a maximum priority degree (step 1004). Judgement is made about whether or not the channel is an idle channel (step 1005). If it is an idle channel, its priority degree P is increased by a priority function .DELTA.P(x) determined by a priority degree modification frequency x and this channel is allocated (steps 1006 and 1007). If it is not an idle channel, the priority degree P is decreased by the priority function .DELTA.P(x) (step 1008). Subsequently, the priority degree modification frequency x is increased by +1. When x reaches an upper limit value xo, the priority degree modification frequency x is not reset but is given as x=xl
    • 在动态信道分配系统中,在每个通信请求中,选择具有最大优先级的信道(步骤1004)。 判断该信道是否为空闲信道(步骤1005)。 如果它是空闲信道,则其优先级P被由优先级修改频率x确定的优先级函数DELTA P(x)增加,并且该信道被分配(步骤1006和1007)。 如果不是空闲信道,则通过优先级函数DELTA P(x)降低优先级P(步骤1008)。 随后,优先级修正频率x增加+1。 当x达到上限值xo时,优先级修正频率x不复位,而是给定为x = x1
