  • Patent number: 8141413
    Abstract: A particulate matter concentration measuring apparatus is configured to measure a concentration of particulate matter in exhaust gas flowing through an exhaust line of a diesel engine. The apparatus includes an exhaust gas extraction line diverging from the exhaust line and having a flow passage cross-sectional area smaller than a flow passage cross-sectional area of the exhaust line. A particulate matter detection filter has a cell wall and is provided in the exhaust gas extraction line. A flow velocity of the exhaust gas passing through the cell wall is more than or equal to approximately 0.02 m/s and less than or equal to approximately 2.0 m/s. A differential pressure sensing part is configured to sense a differential pressure generated between an inlet and an outlet of the particulate matter detection filter.

  • Publication number: 20090272725
    Abstract: A difference processing circuit receives input of welding images taken by a CCD camera in real time and then differentiates power monitoring images recorded in a memory from welding images to obtain difference processing reflected light images. Due to the difference processing performed by a difference processing circuit, foreign matter images included in welding images and power monitoring images are eliminated and the difference processing reflected light images that are obtained do not include any foreign matter images. A quality judgment device uses the difference processing reflected light images obtained by a difference processing circuit and conducts a quality judgment. As described above, since difference processing reflected light images do not include any foreign matter images, a quality judgment device does not receive any influence from the foreign matter that is adhered to the protective glass and can conduct an excellent evaluation of the welding quality.

  • Patent number: 6728258
    Abstract: In a multi-processor system interconnecting processor units, memory units, and input/output units connected to input/output devices via a crossbar switch having a plurality of ports, the transmitter of each processor unit has a circuit for determining a destination of an access request in the following manner. For an access request to a main memory, the access request is transferred to all processor units and one memory unit storing the data to be accessed. For an access request to a memory mapped register of the input/output device, the access request is broadcast to all input/output units. For an access request to a memory mapped register belonging to any one of the processor units, memory units, and input/output units, the access request is broadcast to all units via the crossbar switch.

  • Publication number: 20040055527
    Abstract: A Czochralski method of producing a single crystal silicon ingot having a uniform thermal history. In the process, the power supplied to the side heater is decreased during the growth of a latter portion of main body, and optionally the end-cone, of the ingot, while power supplied to a bottom heater is gradually increased during growth the same portion. The present process enables a substantial portion of an ingot to be obtained yielding wafers having fewer light point defects in excess of about 0.2 microns and improved gate oxide integrity.
