    • An optical pickup includes a light source, a light converging portion for converging a light emitted from the light source on the recording surface of an optical disk, a signal detecting portion for detecting a light reflected by the recording surface and converting this light into a specified electric signal, a first optical element, which is arranged between the light source and the light converging portion for forming a plurality of diffracted lights from the light emitted from the light source, and a second optical element, which is arranged between the light source and the light converging portion and in which an optical path for the light reflected by the recording surface of the optical disk and an optical path for the emitted light are different from each other. Thus, without increasing the weight of a movable portion and also without increasing the manufacturing costs of a condenser lens, reproducing is performed from a high density optical disk and a conventional low density optical disk, which are different in standard.
    • 光拾取器包括光源,用于会聚从光源发射的光在光盘的记录表面上的聚光部分,用于检测由记录表面反射的光并将该光转换成指定的光的信号检测部分 电信号,第一光学元件,其布置在光源和聚光部分之间,用于从光源发射的光形成多个衍射光;以及第二光学元件,其布置在光源和 光会聚部分,由光盘的记录表面反射的光的光路和用于发射的光的光路彼此不同。 因此,在不增加可动部分的重量的同时,也不会增加聚光透镜的制造成本,从标准不同的高密度光盘和传统的低密度光盘执行再现。

    • An internal combustion engine according to the present invention includes an exhaust treatment apparatus provided in an exhaust passage, and a burner apparatus provided upstream of the exhaust treatment apparatus to increase an exhaust temperature. The burner apparatus includes at least a fuel addition valve that allows fuel to be added into exhaust and ignition means for igniting the fuel added via the fuel addition valve. The fuel addition valve is driven open when fuel is added via the fuel addition valve. The amount of fuel added via the fuel addition valve per unit time is increased beyond a predetermined reference amount when the detected amount of intake air exceeds a predetermined threshold value. The probability of successful ignition by the ignition apparatus is increased, and a flame is prevented from being blown out. Thus, the burner apparatus can demonstrate sufficient ignition performance and sufficient combustion performance.
    • 根据本发明的内燃机包括设置在排气通道中的排气处理装置和设置在排气处理装置上游以增加排气温度的燃烧器装置。 燃烧器装置至少包括能够将燃料添加到排气中的燃料添加阀和用于点燃通过燃料添加阀添加的燃料的点火装置。 当通过燃油添加阀添加燃料时,燃油添加阀被打开。 当检测到的进气量超过预定阈值时,每单位时间通过燃料添加阀添加的燃料量增加超过预定参考量。 通过点火装置成功点火的概率增加,并且防止火焰被吹出。 因此,燃烧器装置可以证明足够的点火性能和足够的燃烧性能。
