  • Patent number: 7677875
    Abstract: A method for controlling measurement in a motor-driven in-line screw type injection molding machine using servo-motors as a measurement driving source and an injection driving source. Control is made so that all of a measured value of back pressure controlled by the measurement servo-motor, a measured value of an astern speed of a screw controlled by the injection servo-motor, and a measured rotational speed of the screw turn zero concurrently at timing when the screw reaches a measurement completion position. Thus, suck-back can be made dispensable.

  • Publication number: 20090297038
    Abstract: Up and down directions of an image are to be precisely judged without a special equipment installed in an image pickup device. An object candidate detecting means detects object candidates from an input image and their angles in the input image. A similarity calculation means calculate the degree of similarity between each detected object candidate and each object stored in advance. An input image angle calculating means judges up and down directions of the input image based on the calculated similarity of each object candidate and the angle of the input image. The input image angle calculating means carries out weighting for the angle of each object candidate in the input image based on its similarity and calculates slant angles with respect to the up and down directions of the input image by using the weighted angles.

  • Publication number: 20090132074
    Abstract: A segment automatic extracting system provides applications with an impressive segment of a musical composition as metadata on the composition by extracting a portion of the composition likely to be widely known by general users irrespective of the number of appearances in the composition. Associated method and program are also described. A first acoustic signature (AS) creating section creates an AS representing the feature value of the acoustic signal of each of contents. An important segment extracting section creates an acoustic segment signature representing the frequently appearing feature value from searching all created ASs. A second AS creating section creates an AS from the composition signal. A common segment extracting section judges whether each acoustic segment signature agrees with a part of the AS of the composition signal and outputs time information by which the AS of the musical signal agreeing with the AS can be specified.

  • Patent number: 7442947
    Abstract: A multicolumn electron-beam exposure system includes: a plurality of column cells, which are arranged above a wafer, and each of which includes an electron gun and deflection means which deflects an electron beam irradiated from the electron gun; common storage means which stores common exposure data used by the plurality of column cells; and size data correcting means which is provided to each of the column cells, and which receives size data on a variable-shaped beam from the common storage means, thus outputting an amount of correction to the size data. The amount of correction is the size data on the variable-shaped beam, which corresponds to the difference between the size of a resist pattern, which has been formed by specifying an intended pattern size and a reference light exposure, and the intended pattern size.

  • Publication number: 20080214031
    Abstract: An electrical connector includes a plurality of contacts to be connected to a cable, a housing for arranging and holding the contacts, a shell dividable into two shells covering the housing and having a holding device for holding the cable, and an insulating member covering the shell. One of the shells is provided with anchoring portions and the other shell is provided with engaging portions so that when both the shells are fitted with each other, the anchoring portions and the engaging portions are engaged with each other to bring both the shells into electrical continuity with each other. Therefore, the shells can be securely held together to achieve reliable electrical continuity between the shells, and at the same time grounding between the cable and the shell and between the shells themselves can be achieved.

  • Patent number: 7354299
    Abstract: An electrical connector includes a plug connector and a receptacle connector detachably fitted with each other. The plug connector comprises a plurality of coaxial cables, a flexible printed circuit board and a ground bar. Each of the coaxial cable has a center conductor, an insulator covering the center conductor, a braid as an external conductor covering the insulator, and a sheath covering the braid. The flexible printed circuit board has lands each connected to the center conductor of the coaxial cable and land portions to which the ground bar is connected. The grand bar has a main portion adapted to contact the braids of the coaxial cables, and fixed portions each positioned contiguously with the main portion and connected to the land portion. The electrical connector achieves the low height geometry of the plug connector and hence that of the receptacle connector and precludes any failed connection between the ground bar and the coaxial cables.
