摘要:
Medical image data is utilized, physical values are assigned to body parts based on image information, and the target organs are separated from the image data to prepare a 3D biodata model to thereby realize a data model unique to a patient, having an internal structure, and enabling dynamic simulation of a live body. The same target part of a body is captured by CT and MRI to obtain medical images. Sets of pairs of CT images and MRI images are set, a plurality of features showing the same locations are selected and set from the sets of CT images and MRI images, a conversion coefficient between the CT images and MRI images is obtained, and this conversion coefficient is used to rearrange the MRI images by projection transforms and linear interpolation, combine them with the contours of the CT images, and correct their positions in the contours. Further, the images are used to prepare a 3D data model.

This invention provides a pull-out device for pulling out a connector from an apparatus to which the connector is connected, including a pulling member having one end attached to the connector and the other end with a locking portion, a locking unit arranged to face the connector and to which the locking portion is locked, and a moving unit arranged to move the locking unit and the apparatus relative to each other so as to separate from each other in a pull-out direction of the connector, thereby causing the pulling member to generate tension that pulls out the connector, wherein the locking unit locks with the locking portion such that, as the tension is generated, the locking portion is freely movable within a plane substantially perpendicular to the pull-out direction.

According to the invention, the rear end of a preceding metal piece and a front end of a succeeding metal piece are heated, pressed and joined prior to the finishing hot rolling. An alternating magnetic field running through the metal pieces in the thickness direction thereof is generated in an end region on opposed faces of the respective metal pieces to perform heating. Another alternating magnetic field whose direction is reverse with respect to that of the former alternating magnetic field is partially generated in the end region on the opposed faces of the metal pieces and in either a region where the metal pieces exist or a region outside width ends of the metal pieces. This assures a uniform heating of the end region on the opposed faces of the metal pieces over their full width to reliably join the both metal pieces to each other.

Method and apparatus for joining metal pieces using induction heating. Metal pieces to be joined are placed end-to-end with a gap between them and induction heated in the thickness portion. To maximize speed and even heating edge-to-edge of the ends, members of a magnetic substance are provided in a gap between the inductor and the piece to be heated, thereby enhancing local heating effect by increasing magnetic flux density. Once heated, the ends are pressed together end-to-end for joining.

A motion picture data decoding system extracts motion picture data from transmitted MPEG data and decodes the extracted motion picture data. A multi-media communication terminal includes a data buffer portion storing the extracted motion picture data per predetermined data unit, the data buffer portion having a capacity of storing a plurality sets of the data unit, motion picture data being accumulated in the data buffer per data unit, and motion picture data being taken from the data buffer portion per data unit and decoded by said decoding portion. In concrete, when the amount of the motion picture data transmitted per data unit and sequentially accumulated in the data buffer exceeds the threshold value and amount of the motion picture data accumulated in the data buffer and being sequentially decoded per data unit, is reduced across the threshold value, to issue a demand for transmission of next data unit for monitoring the data buffer portions and making the decoding process efficient. By this, even when transmission efficiency is fluctuated due to load or go forth on a CPU, the motion picture can be smoothly reproduced and displayed.

A semiconductor device of the SOP type packaged on a lead frame and separated individually is fed into a lead-forming position by a holder, and the distal ends of leads arrayed on one side of the semiconductor device are imaged by a camera. The image data from the camera is processed by a recognition unit, which outputs the actual position of the semiconductor device. If the recognized actual position is different from the position to start forming leads, then a controller actuates the holder to eliminate the positional error and to position the semiconductor accurately in the lead-forming position. Based on data corresponding to the type of the semiconductor device, the lead bases of the leads are held by a lead-fixing finger assembly, and the distal end portions of the leads are bent arcuately by a lead-forming finger assembly, thereby forming the leads to a predetermined shape. Then, the leads on the opposite side of the semiconductor device are similarly formed to shape after the semiconductor device has been turned 180.degree. by the holder. To form the leads arrayed on four sides of a semiconductor device of the QFP type, two arrays of leads are simultaneously formed to shape by lead-forming devices disposed one on each side of the lead-forming position, and then two other arrays of leads are simultaneously formed by the lead-forming assemblies. Therefore, the leads can be formed to shape in two cycles of operation.
