  • Publication number: 20230274441
    Abstract: An analysis apparatus includes a two-dimensional photographing unit 20, a three-dimensional photographing unit 30, and a computer 50 serving as an analysis unit. The two-dimensional photographing unit 20 two-dimensionally photographs a sample, to acquire a two-dimensional image D2. The three-dimensional photographing unit 30 three-dimensionally photographs the sample to acquire a three-dimensional image D3. The computer 50 analyzes the two-dimensional image D2 and outputs a two-dimensional analysis result R2, first. Subsequently, the computer 50 analyzes the three-dimensional image D3 and outputs a three-dimensional analysis result R3. At that time, the computer 50 analyzes the three-dimensional image D3 using an indicator included in the two-dimensional analysis result R2. This can improve the accuracy of the three-dimensional analysis result R3.

  • Publication number: 20230230268
    Abstract: An image display method includes the following operations (a) to (e). The (a) is of obtaining a plurality of two-dimensional images by two-dimensionally imaging a specimen, in which a plurality of objects to be observed are present three-dimensionally in the specimen, at a plurality of mutually different focus positions. The (b) is of obtaining image data representing a three-dimensional shape of the specimen. The (c) is of obtaining a three-dimensional image of the specimen based on the image data. The (d) is of obtaining the two-dimensional image selected from the plurality of two-dimensional images or a two-dimensional image generated to be focused on the plurality of objects based on the plurality of two-dimensional images as an integration two-dimensional image. The (e) is of integrating the integration two-dimensional image obtained in the (d) with the three-dimensional image obtained in the (c) and displaying an integrated image on a display unit.

  • Patent number: 4300381
    Abstract: A method of producing an insert for the combustion chamber of a diesel engine having an oblique injection port comprising inserting a cylindrical work blank into a die, then cold- or hot-compressing such cylindrical work blank between a punch and counter-punch to form a compressed center-recessed shape, forming an oblique recess in at least one side of the bottom of the center recess of said shape at such an end position as to correspond to the injection port to be formed, and then developing a hole in said oblique recess in conformity with the configuration and extent thereof.
