    Abstract: Disclosed is an efficient heat treatment method which can be performed in a short time. Specifically disclosed is a method for heat-treating a steel material wherein a plastically deformed steel work is introduced into a heat treatment furnace when the work still retains the heat applied thereto during the plastic deformation, then the work is heated preferably at a heating rate of 15-50 DEG C./min and held at a temperature between Ac1 and Ac3 for 10 minutes or less, and then the work is slowly cooled at a cooling rate of 5-45 DEG C./min. This heat treatment method enables to easily produce a steel material having a uniform metal structure by simple facilities.

  • Patent number: 7396797
    Abstract: A method for producing a catalyst for a fuel cell is provided which is capable of improving output characteristics of the fuel cell. Metal fine particles making up the catalyst for the fuel cell to be used as a fuel electrode and air electrode are formed by reducing platinum salt with molybdenum carbonyl. The catalyst for the fuel cell is formed by supporting platinum-molybdenum fine particles on carbon particles. By employing this reducing method, platinum-molybdenum fine particles being small in size and high in dispersibility can be obtained, making the catalyst for the fuel cell highly active. By constructing the fuel and air electrodes using the catalyst for the fuel cell, high outputs from the fuel cell are made possible.

  • Publication number: 20080127000
    Abstract: A closed-loop IC design optimization process by automatically or manually creating design-specific cells with desired characteristics (e.g., performance, area, power, noise, etc.), which will be then implemented as a standard cell (also known hereafter as metacell), from a set of post-layout patterns. A post-layout pattern represents a part or whole of a standard cell and contains information regarding the pattern including, but not limited to, layout, timing, area, power and noise. As the metacells are created from post-layout patterns, the inaccuracies of prior dynamic library techniques are easily avoided. Such metacells, being design-specific, are optimized to satisfy the constraints imposed by the design context, thus bringing the powerful design-specific customization to standard cell-based design methodology.

  • Publication number: 20080111889
    Abstract: Movement of an imaging device is detected using a camera shake detection sensor or a motion vector obtained from an image signal, and camera shake correction is performed by shifting an extraction frame (valid photographing region) within a photographable maximum region based on the motion detection result. When movement of the imaging device is causing a face region located at the edge of the extraction frame to move towards out of the frame, it is determined that the movement is due to camera shake, and the extraction frame is moved so that the face region can stay within the frame. Meanwhile, when movement of the imaging device is causing the face region to move inward within the frame, it is determined that the movement is due to a pan or tilt operation, and position control is performed so that the deliberate movement is not inhibited.

  • Publication number: 20080024620
    Abstract: An image-taking apparatus generates an output image from a photographed image obtained by photographing and displays this output image on a display screen of a display section. The image-taking apparatus includes a recognition processing section for recognizing a specific subject (facial region of a person, or a facial component such as eyes) included in the photographed image. Referring to results of this recognition, the image-taking apparatus evaluates the dimension of the specific subject in each photographed image. If the dimension evaluated is relatively large, a relatively small magnification ratio to be employed upon the generation of the output image from the photographed image is provided. If the dimension evaluated is relatively small, a relatively large magnification ratio to be employed upon the generation of the output image from the photographed image is provided. As a result, the dimension of the specific subject in the output image is kept substantially constant.

  • Publication number: 20070222884
    Abstract: Based on, for example, the image at the start of a movie, a thumbnail image is tentatively generated and is stored in a header file. If a predetermined triggering condition is fulfilled during movie shooting, a thumbnail image is generated from the frame image at the timing that the triggering condition is fulfilled, and the thumbnail image existing in the header file is replaced with the newly generated thumbnail image. The triggering condition is fulfilled, for example, if, after zooming-in, the angle of view has been kept fixed for a predetermined period or longer, or if the focus has been kept locked for a predetermined period.
