  • Publication number: 20070270987
    Abstract: The minimum value detecting circuit detects a minimum value, excluding zero, of a coefficient according to a dequantized acoustic signal. The correction coefficient computing circuit computes a correction coefficient based on the minimum value and white noise outputted from the white noise storage which stores white noise. In this process, a correction coefficient is computed by, for example, dividing the minimum value obtained by the minimum value detecting circuit by a value which is twice the maximum value or the mean value of white noise stored in the white noise storage. The correction value computing circuit computes a correction value by multiplying the correction coefficient computed by the correction coefficient computing circuit by white noise stored in the white noise storage. A corrected coefficient is computed by adding the correction value obtained as described above to a frequency band having a null coefficient according to a dequantized acoustic signal.

  • Patent number: 7150084
    Abstract: Machining portions such as a cutter portion, a slider inserting portion and an upper stopper attaching portion are provided around the vertical axis of a fixed table portion in order of machining. A fastener chain cut to have a predetermined length is held by the fixed table portion and a gripper of a rotator provided around the same vertical axis. The fastener chain is rotated and transferred to each of the machining portions based on the intermittent rotation and control of the rotator in the holding state in the gripper. Every time a predetermined machining is completed in each of the machining portions for the fastener chain rotated and transferred intermittently, it is possible to rotate and transfer the fastener chain simultaneously and intermittently to the next machining portion, thereby carrying out the necessary machining continuously.

  • Patent number: 7137177
    Abstract: Coil-like or zigzag-like linear fastener elements formed of synthetic fiber mono-filaments are attached such that coupling heads project from a side edge of a fastener tape and at least one coupling head thereof located at a top end is moved to the inside of the fastener tape so as to substantially coincide with the side edge. Then, the fastener element is fused to the fastener tape in a state in which an inverted portion project inwardly while the coupling heads are in a non-coupling condition, so as to form a top end stop. The top end stop formed of the linear fastener element includes plasticity and provides an excellent tactile feeling without any burr on the surface thereof.
