A power semiconductor device comprises a semiconductor substrate, a gate electrode region (control electrode region), a cathode electrode region (first main electrode region), an anode electrode region (second main electrode region) and a guard ring. The semiconductor substrate has a side surface portion having a vertical portion formed substantially vertical to a main surface and a mesa portion connected to the vertical portion in a cross section. The gate electrode region is formed in a first main surface of the semiconductor substrate. The cathode electrode region is formed in part of a surface of the gate electrode region. The anode electrode region is formed in a second main surface of the semiconductor substrate. The guard ring is formed in the second main surface of the semiconductor substrate and annularly surrounds the anode electrode region. With this constitution provided is a power semiconductor device which makes the impurity diffusion length of the anode electrode region shallower in order to ensure reduction in recovery loss.

The invention provides a combustion apparatus which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a combustion apparatus provided with a burner burning a fuel within a furnace in a theoretical air ratio or less, and an air port supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region. Further, the invention provides a wind box which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a wind box having an air port arranged in a back flow side of the burner and supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region.

The image reading apparatus for photoelectrically reading an original image includes an image reading device and a detection device. The image reading device has first reading unit for reading a visible image carried by the original image and a second reading unit for reading a reference image in a wavelength different from that used to read the visible image. The detection device acquires correlative pixel distribution information between a visible image signal and a reference image signal using the visible image and the reference image having been read by the image reading device and detects an image defect caused by a foreign particle deposited on the original image and a flaw of an original using the information. The apparatus can detect the image defect of the film with pinpoint accuracy without erroneous detection without depending upon a type of the film and a state of the image, and output in excellent productivity an image of high quality whose image defect has been preferably corrected.

Disclosed is a method for obtaining a precise detected value of a similarity between voices or the like. Standard and input pattern matrices, each having a voice feature amount as a component, are prepared (S1 and S2). A reference shape having a variance different for each specified component of the pattern matrices is prepared, and positive and negative reference pattern vectors, each having a value of the reference shape as a component, are prepared. Then, while the specified component (a center of the reference shape) being made to move to each component position j1=1 to m1, j2=1 to m2 of the standard pattern matrix, a shape change between the standard and input pattern matrices is substituted for shape changes of the positive and negative reference pattern vectors. And, an amount of change in kurtosis of each reference pattern vector is numerically evaluated to obtain a shape change amount Dj1j2 (S3). Then, a value of a geometric distance between the pattern matrices is calculated from Dj1j2 (S4).

A low-cost contact detection sensor and contact detection method for easily detecting a contact by a third party is provided. A contact detection sensor comprises an antireflection structure including structure elements having a predetermined shape which are put in an array periodically at a pitch smaller than a wavelength of visible spectrum; and a substrate including the antireflection structure in at least a part of a surface portion thereof. The antireflection structure distinguishes whether the detection target is contacted by a human body or not based on a change in reflectance which occurs to an area of the detection target contacted by the human body when the detection target is contacted by the human body.
