  • Patent number: 7593556
    Abstract: A sample inspection system has line sensors that generate sample picture data for layers of a sample disposed at different depths of the sample. The line sensors are arranged parallel to each other and displaced from each other in a vertical direction relative to the sample. A lens system focuses the layers of the sample at the different sample depths on the respective line sensors so that pictures of the layers at the different sample depths are read as line picture data by the line sensors. The sample inspection system includes an apparatus that stores the generated sample picture data, allows a planar region of the sample to be designated by a user for display, extracts picture data corresponding to the designated planar region for each of the sample layers from the sample picture data in response to designation of the planar region, and stores the extracted picture data as a set.

  • Patent number: 7542396
    Abstract: To achieve stable, high capacity, high speed recording. Of two light beams emitted from a light irradiation means, one or two beams are made pass through an optical path changeable member whereof at least one of the thickness and refractive index changes continuously or in two or more steps immediately after emission from the light irradiation means, so that a difference is introduced into the optical path length of the two beams, and the focusing point of one beam is made to vary to coincide with a position in the recording layer used for playback or recording. Another light beam is used for servo. Converging of light during recording or read of a multilayer recording medium is performed with higher precision than in the prior art, so higher density, higher capacity recording/playback can be performed.

  • Patent number: 7117666
    Abstract: An engine control device is configured to cause an engine to operate at the optimum combustion mode according to the load when warming up of an emissions purification catalyst is required, and to obtain reduced HC discharged from the engine and accelerated warm-up of the catalyst. The engine control device performs stratified combustion with a compression stroke injection in a low-load region according to the engine load, and performs double-injection combustion with an intake stroke injection and a compression stroke injection in an intermediate load region, when warming up of the catalyst is required. In a high-load region, the engine control device performs homogenous combustion with an intake stroke injection.

  • Patent number: 7104249
    Abstract: A control apparatus is configured to achieve considerably delayed ignition timing and combustion stability, and to bring about an increase in exhaust gas temperature and a reduction in HC discharge when the engine is cold. Normal stratified combustion operation and homogeneous combustion operation are carried out when warming has been completed and the coolant temperature of the internal combustion engine has exceeded 80° C. In an injection operation at the top dead center, the injection start timing ITS occurs prior to compression top dead center (TDC) and the injection end timing ITE occurs after compression top dead center (TDC), whereby fuel injection is carried out so as to straddle the compression top dead center. The ignition timing ADV occurs after compression top dead center (TDC) and ignition occurs with a timing that is delayed from the injection start timing ITS.

Upon start-up of the engine (1), intake stroke fuel injection is performed at the first combustion opportunity, and compression stroke fuel injection is switched to from the second combustion opportunity onward. In so doing, switching of the combustion system is performed early and independently of the engine rotation speed.

  • Patent number: 7024851
    Abstract: An engine control device is configured to perform optimum combustion control according to environmental conditions when warming up of a catalyst for emission purification is required. The engine control device performs stratified combustion by the compression stroke injection at the time of startup, when warming up of the catalyst is required. However, under conditions of low air density, stratified combustion by compression stroke injection is prevented, and either homogenous combustion by intake stroke injection is performed, or double injection combustion by intake stroke injection and compression stroke injection is performed. Thus, the engine control device maintains starting properties and prevents adverse effects on engine operability.
