    • The present invention relates to an image data reconstructing apparatus for reconstructing an original image by dividing image data into a plurality of blocks each comprising NXN picture elements, performing two-dimensional orthogonal transform on each of said blocks, quantizing and encoding the result of said transform, decoding the encoded result, dequantizing and two-dimensional inverse orthogonal transforming the above result, wherein an operation associated with the multiplication is skipped if a multiplication by zero is detected when two-dimensional inverse orthogonal transform is performed. Before performing dequantization, two block volume of buffer is provided before or after performing two-dimensional inverse orthogonal transform for executing a pipeline process.Furthermore, two-dimensional inverse orthogonal transform is performed by repeating two times a process of one-dimensional inverse orthogonal transform and matrix transposition, thus the matrix transposition being performed as the result of one-dimensional inverse orthogonal transform which is stored in buffer.
    • 本发明涉及一种图像数据重建装置,用于通过将图像数据分割成包括NXN图像元素的多个块来重构原始图像,对每个所述块执行二维正交变换,对所述变换的结果进行量化和编码 对所述编码结果进行解码,对所述结果进行去量化和二维逆正交变换,其中如果在执行二维逆正交变换时检测到乘以零,则与所述乘法相关联的操作被跳过。 在执行解量化之前,在执行二维逆正交变换之前或之后提供两个块体积的缓冲器用于执行流水线处理。 此外,通过重复两次一维逆正交变换和矩阵转置的处理来执行二维逆正交变换,因此作为存储在缓冲器中的一维逆正交变换的结果执行矩阵转置。

    • In a multiplex communication method for implementing multiplex communication between a plurality of circuit units, a format of a transmitted data signal not only is formed of serial data consisting of first data, second data that has the same content as the first data, and a parity that indicates the number of logical 1s or logical 0s forming the first data and the second data is even or odd, but also selects as regular data in such a manner that when the transmitted data signal is received, if the first data and the second data are compared with each other and judged to be coincident with each other from the comparison, then the coincident data is selected as the regular data and that if the first data and the second data are judged to be different from each other from the comparison, then a logic of the parity is checked and either the first data or the second data corresponding to the logic of the parity is selected as the regular data.

    • A covers opening/closing sequence regulation system includes a first cover and a second cover openably and closably attached to a housing. The first and second covers are provided in a way that the first cover becomes openable and closable while the second cover is in a fully-closed state, and that the second cover becomes unable to be fully-closed from an opened state while the first cover is in a fully-closed state. A regulation mechanism is configured to stop the first cover in a spaced-out position, which is spaced out from a fully-closed position of the first cover, in an operation of closing the first cover toward the fully-closed position with the second cover being in an opened state. The second cover is openable and closable while the first cover is in the spaced-out position.
