Articles entered into a sorting system are identified by means of an article identification device . An allocation ratio is selected from an allocation ratio table based on the identifying information from the article identification device . Chute selection information is obtained for a sorter based on the allocation ratio by means of a calculator , which in one embodiment uses a random number generator to make a weighted calculation and a deviation reduction mechanism to reduce the deviation of the accumulated weighted calculation results. A controller selects a chute such that the articles entered into the system will be distributed in accordance with the article allocation ratio, and provides the chute selection information to the sorter . The sorter , based upon the chute selection information, conducts sorting by dropping the articles entered into the system into the appropriate chute

For one of memory divisions that is selected at a time as a selected division N(m) in a memory for use in putting a sound processing device in operation of generating a three-dimensional image of an acoustic field, a difference signal is produced to represent a clock count minus a delay count n(m) specific to the selected division and to have more and less significant bits. For use as an address signal supplied to the memory, a part of the more significant bits is changed to a like part of a memory space address specific to the selected division. As usual, the less significant bits are used to indicate read aR(i(m)) and write W(i(m)) pointers which are spaced in the selected division by the delay count. The part may be specified to be wide and narrow when the selected division is narrow and wide. Alternatively, the part may have a predetermined bit width.

A digital vertical synchronization system for use in a television receiver is disclosed. A vertical synchronization separator circuit receives a composite synchronizing signal and separates a vertical synchronizing signal from the composite signal. A clock counter receives a clock input signal having a frequency equal to a positive integer N times as high as the frequency of a horizontal synchronizing signal separated from the composite signal. The clock counter produces a first output signal having a repetition frequency substantially equal to the vertical synchronizing signal and having a pulse width required for generating a vertical deflection signal and a second output signal having a pulse width equal to or smaller than the pulse width of the vertical synchronizing signal. A phase comparator compares the phases of the second output signal of the clock counter and the vertical synchronizing signal and produces a reset signal when the phases of the two signals are not coincident. The reset signal is applied to the reset terminal of the clock counter.
