摘要： A phase synchronization method uses a removal path for removing an error component contained in an input signal and a delay addition path for adding a delay corresponding to a processing time period taken to remove the error component in the removal path. The removal path includes an averaging section. The averaging section includes a shift register and an obtaining unit. The shift register stores as many data as the maximum number of data to be averaged and successively receives processing data from which the error component has been extracted in the removal path. The obtaining unit obtains, among the successive processing data input to the shift register, as many processing data as the number of data to be averaged from a position near the center toward both ends in the shift register.

摘要： Fibrous boiled fish paste is produced by adding water to minced meat, mixing both with agitation, molding the mixture into a certain shape, subjecting it to setting, dividing it finely into the form of fibers or flat pieces extending in parallel and then heating the resulting finely divided product without separating each fiber or flat piece individually. The resulting boiled fish paste comprises an inner part coated with an outer surface forming a pellicle united to the inner part. The inner part is divided finely into the form of fibers or flat pieces in parallel to such a degree that each fiber or flat piece separates individually with ease in the mouth upon eating. This boiled fish paste is united in a body in appearance, but it loosens immediately in fiber-like manner in the mouth upon eating and it has an improved mouth feel.
