摘要： A hydraulic operation controlling unit where the engine can be driven stably at a target output torque point and reduction in the work speed can be prevented at the time of light load, includes an engine control unit controlling the output of an engine, so that the output properties of the engine become equi-horsepower properties or approximately equi-horsepower properties in a predetermined engine speed range (N2 to N6) that includes engine speed N3, which corresponds to a matching point M3. A controlling unit increases or reduces the absorbing torque of a hydraulic pump in response to an increase or decrease in the engine speed, and thus, controls the absorbing torque of the hydraulic pump so as to make the output torque T3 of the engine, which corresponds to matching point M3, and the absorbing torque of the hydraulic pump coincide with each other.

摘要： A periodic structure is to be successively formed over an extensive area with a uniaxial laser beam. Such method includes irradiating a uniaxial laser beam near an ablation threshold to a surface of a material; and executing an overlapped scanning on the irradiated region, so as to cause an ablation by interference between an incident beam and a surface scattered wave along the material surface; increasing the scattered wave; causing an interference at an interval equal to a wavelength of the laser beam, to thereby cause spontaneous formation of a periodic structure. The periodic structure can be made to have a different ripple spacing by changing an incident angle of the laser beam to the material surface. When the laser incident beam has an angle, the ripple spacing can be changed by changing a scanning direction.

摘要： This invention achieves high-quality separation of mixed signals in situations where the relationship between the number of signal sources N and the number of sensors M is such that N>M. First, the values of the observed signal observed by M sensors are transformed into frequency domain values, and these frequency domain values are used to calculate the relative values of the observed values between the sensors at each frequency. These relative values are clustered into N clusters, and the representative value of each cluster is calculated. Then, using these representative values, a mask is produced to extract the values of the signals emitted by V (1≦V≦M) signal sources from the frequency-domain signal values, and this mask is used to extract the signal values emitted by V signal sources from these frequency-domain signal values. After that, if V=1 then the limited signal is output directly as a separated signal, while if V≧2 then the separated values are obtained from this limited signal by subjecting it to separation techniques such as ICA.
摘要翻译：本发明在信号源数目N与传感器数量M之间的关系为N> M的情况下实现混合信号的高质量分离。首先，由M个传感器观察到的观测信号的值被变换为频域值，并且这些频域值用于计算每个频率下传感器之间的观测值的相对值。将这些相对值聚类为N个簇，并计算每个簇的代表值。然后，使用这些代表值，产生掩模以从频域信号值中提取由V（1 <= V <= M）个信号源发射的信号的值，并且该掩码用于提取信号值由V信号源从这些频域信号值发射。之后，如果V = 1，则限制信号直接作为分离信号输出，而如果V> = 2，则通过对分离技术（如ICA）进行分离，从该有限信号获得分离值。

摘要： In an exhaust gas purification device for an internal combustion engine, a NOX occluding and reducing catalyst is disposed in the exhaust gas passage of an engine. The NOX occluding and reducing catalyst absorbs NOX in the exhaust gas when the air-fuel ratio of the exhaust gas is at a lean air-fuel ratio and releases and reduces NOX when the air-fuel ratio of the exhaust gas is at a rich air-fuel ratio. The air-fuel ratio of the exhaust gas flowing out from the catalyst is detected by an air-fuel ratio sensor disposed in the exhaust gas passage downstream of the catalyst. When the air-fuel ratio of the exhaust gas flowing into the catalyst is changed from a rich air-fuel ratio to a lean air-fuel ratio, the air-fuel ratio of the exhaust gas flowing out from the catalyst stays at a stoichiometric air-fuel ratio before it changes to a lean air-fuel ratio. The length of the period in which the air-fuel ratio of the exhaust gas flowing out from the catalyst stays at a stoichiometric air-fuel ratio corresponds to the magnitude of the ability of the NOX occluding and reducing catalyst as a reducing catalyst. Thus, by measuring the length of the stoichiometric air-fuel ratio period of the exhaust gas flowing out from the NOX occluding and reducing catalyst, the ability of the NOX occluding and reducing catalyst as a reducing catalyst can be precisely evaluated.

摘要： A fuel injection control device in which it is determined whether the air-fuel mixture is lean or rich at a predetermined crankangle during a lean-rich discriminating time at the time of acceleration. The lean-rich discriminating time is shortened as the degree of the acceleration becomes larger, and the times of being lean and the times of being rich within the lean-rich discriminating time are calculated. When the times of being lean are larger than the times of being rich, and the difference therebetween is larger than a predetermined value, the accelerating increasing rate of the amount of fuel fed into the engine cylinder is increased.
