  • Publication number: 20090016039
    Abstract: A structure for attachment of a shield case to a circuit board. Electronic components are mounted at one face of the circuit board. The shield case is for covering the electronic components and blocking electromagnetic waves. The attachment structure includes toe portions, formed to protrude from the shield case, and holes formed in the circuit board, at which the toe portions can be inserted. The toe portions are fixed to the circuit board by being inserted into the holes and soldered to soldering lands at the other face of the circuit board. Thus, it is possible to prevent solder balls and solder flux entering the shield case, it is further possible to reserve space for soldering lands, with sizes that are required for fixing of the shield case, at a rear face of the circuit board, and it is possible to attach the shield case to the circuit board strongly.

  • Publication number: 20080090044
    Abstract: When neighboring ceramic substrates are split apart by linear snaps, through-holes and holes with floors, which are formed across the snaps, are also split apart. By splitting apart such a ceramic aggregate substrate along the snaps, it is possible to obtain numerous ceramic substrates, in end faces of which recess portions are formed. In comparison with a case of splitting apart such that throwaway substrates are formed at surroundings of ceramic substrates, a number of the ceramic substrates that are split apart from one ceramic aggregate substrate is larger. Therefore, it is possible to keep a unit cost for each of the ceramic substrates lower.

  • Patent number: 7242794
    Abstract: Processing, in which a first shape-dependent filter in accordance with a shape of a microcalcification pattern is utilized, is performed on an object image, and a fine structure image, which illustrates a fine structure area embedded in the object image, is formed. Thereafter, enhancement processing, in which a second shape-dependent filter in accordance with the shape of a microcalcification pattern is utilized, is performed on the fine structure image, and an enhancement-processed image, in which the microcalcification pattern has been enhanced, is formed. A microcalcification pattern candidate is then detected by use of the enhancement-processed image.

  • Patent number: 7242795
    Abstract: Prospective micro calcification points in a radiation image of an object are extracted on the basis of image data representing the radiation image and clustered into cluster areas. A plurality of areas are set in the radiation image, and fluctuation in size and/or fluctuation in density of the prospective micro calcification points in each of the areas is obtained. Detected areas are extracted from the plurality of areas on the basis of the fluctuation in size and/or the fluctuation in density of the prospective micro calcification points in each of the areas, and each interconnected area where a predetermined number of or more extracted detected areas are continuous is set as a cluster area.

  • Patent number: 7194123
    Abstract: Processing for detecting an abnormal pattern candidate embedded in a medical image having been obtained from an image recording operation is performed on an image signal representing the medical image. In cases where the image signal is one which has been subjected to predetermined signal processing, correction processing is performed on the image signal such that the abnormal pattern candidate detecting processing performed on the image signal, which has been subjected to the predetermined signal processing, does not depend upon the predetermined signal processing. The abnormal pattern candidate detecting processing is then performed on the image signal, which has been obtained from the correction processing.

  • Patent number: 7027631
    Abstract: An anomalous shadow detection system capable of obtaining stable detection capacity across all facilities into which the system is introduced, regardless of variations in the conditions of the image obtaining environments of each facility is provided. An image obtaining means obtains an image of a standard-phantom, and an image readout means obtains phantom-image data thereof. Said phantom-image data is input to an evaluative model detecting means which detects evaluative models contained within the image of the standard-phantom. An evaluating means compares the detected evaluative models to a desired detection level. If the detected evaluative models are of a different detection level than the desired detection level, a parameter setting means resets the detection parameter, depending on the result obtained by the evaluating means 32, and the above processing of the phantom-image data is repeated until the detection result and the desired detection level are the same.
