Abstract: A high voltage generating circuit includes a boosting portion (e.g., a trigger coil (22)) for boosting DC voltage delivered from a DC power supply (26) so as to deliver high voltage at a secondary side, a switching element (e.g., a MOSFET (23)) for turning on and off current flowing in the primary side of the boosting portion, and a pulse signal generating portion (24B) for generating a pulse signal for controlling on and off of the switching element.

Abstract: When first and second images are input, a partial image feature calculating unit calculates feature values of partial images of the two images. A maximum matching score position searching unit searches for a position of the second image that attains to the highest matching score with each of the partial images of the first image. A movement-vector-based similarity score calculating unit calculates similarity between the first and second images, using information related to that partial image whose movement vector has direction and length within a prescribed range, which movement vector representing positional relation between a reference position for measuring, for each of the partial images, the position of the partial image in the first image and the position of the maximum matching score corresponding to the partial image searched out by the maximum matching score position searching unit. The images as the object of collation may belong to the same category classified based on the feature values.

Abstract: An image comparing apparatus receives two images to be compared with each other. For each of the two images, respective feature values of partial images in the image are determined. With respect to each partial image in one of the images, the position of a partial image that is in the other image and that has the maximum score of matching with the partial image in that one image is searched for. The search range is limited to partial images selected according to three or five different feature values determined in advance. Then, the similarity score representing the degree of similarity between these two images is calculated, based on information about a movement vector indicating a relation between a reference position for locating the partial image in one image and the maximum matching score position that is searched for with respect to the partial image. Images to be searched belong to the same category as that of the partial image.

Abstract: A router is formed by an M-input, 1-output junction unit and a 1-input, N-output branching unit. Where M and N satisfy the relation of (M>N), the transfer rate of a path between the junction unit and the branching unit is made the total sum of the transfer rates of inputs of IN1 to INM, whereby N times faster transfer becomes possible.

Abstract: A self-synchronous logic circuit includes scan test compliant registers holding data and forming stages of a pipeline, and scan test compliant self-synchronous signal control circuits corresponding to respective registers and performing handshake to transfer clocks. In accordance with the clocks transferred by the scan test compliant self-synchronous signal control circuits, data processing among the scan test compliant registers proceeds. In addition to normal data processing, the scan test compliant registers have a function of serially transferring contents thereof at the time of a test. The scan test compliant self-synchronous signal control circuits are set to a state that corresponds to the end of a third way of the handshake, at the time of a test.
