    • An exhaust gas recirculation control device in a diesel engine, capable of suppressing NOx and smoke discharged. A first temperature sensor (11) is provided at a portion more on the upstream side than a portion where a suction air path (3) joins an exhaust gas recirculation path (4), and a second temperature sensor (12) is provided on the downstream side. Further, an engine load detection sensor (6) and an engine speed detection sensor (7) are arranged. The exhaust gas recirculation control device also has memory means where the temperature of suction air before it is mixed with an exhaust gas and a temperature value at a second temperature sensor installation position are previously memorized, the temperature value corresponding to an appropriate exhaust gas recirculation amount that is uniquely defined by an engine load and an engine speed. Further, judging means is provided. The judging means compares the corresponding temperature value memorized in the memory means and a value detected by the second temperature sensor. When the detected value is within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be appropriate, and when the detected value is not within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be abnormal.
    • 一种柴油发动机中的排气再循环控制装置,其能够抑制NOx排出。 第一温度传感器(11)设置在比吸气通路(3)连接排气再循环路径(4)的部分更靠上游侧的部分,第二温度传感器(11)设置在第二温度传感器 下游侧。 此外,配置有发动机负荷检测传感器(6)和发动机转速检测传感器(7)。 废气再循环控制装置还具有存储装置,其中在其之前的吸入空气的温度与排气混合并且在第二温度传感器安装位置处的温度值被预先存储,对应于适当的废气再循环量的温度值 这是由发动机负载和发动机速度唯一定义的。 此外,提供判断装置。 判断装置比较存储在存储装置中的相应温度值和由第二温度传感器检测的值。 当检测值相对于温度值在预定范围内时,循环排气量被确定为适当,并且当检测值相对于温度值不在预定范围内时,确定循环排气量 异常

    • A cassette loading apparatus of the present invention is capable of loading a plurality of tape cassettes different in size from each other, while achieving the following effects. Tape damage or tape breakage when the lids of the tape cassette are opened/closed can be prevented. The opening height of a rear lid when the lids are opened can be maintained constant, and at the same time, a gap is not produced between the lids when the lids are closed, thereby preventing an increase of drop-outs due to the invasion of dust or the like into the gap. Damage of a rear lid opener or the rear lid when the lids are opened/closed can be prevented. These effects are accomplished by providing the tape cassettes with rear lids each having a laterally extending protruding portion and a bottom end located below the protruding portion. The cassette loading apparatus has the rear lid opener positioned and configured to advantageously abut against the protruding portion of the rear lid in order to open the rear lid.
    • 本发明的盒式磁带装载装置能够将不同尺寸的多个磁带盒装载在一起,同时实现以下效果。 可以防止磁带盒的盖子打开/关闭时的磁带损坏或磁带破损。 当打开盖子时,后盖的打开高度可以保持恒定,同时当盖子关闭时盖子之间不会产生间隙,从而防止由于入口引起的脱落增加 灰尘等进入间隙。 可以防止盖盖打开/关闭时后盖开启器或后盖的损坏。 这些效果通过提供具有后盖的带盒来实现,每个盖具有横向延伸的突出部分和位于突出部分下方的底端。 盒式装载装置具有后盖开启器,其定位和构造成有利地抵靠后盖的突出部分以打开后盖。
