A packet processing type determiner includes a non-secure packet processing module configured to process packets received over a single socket using a non-secure protocol. These compounds have ORL1-receptor agonist activity, and are thus useful as analgesics or the like in mammalian subjects. The workers determining section can determine the worker of the objective work appropriately based on set worker information, current worker information, the worker intension, and the like. A first type of the output signal is proportional to the sum of the first signal frequency-converted to a third center frequency f3 and the second signal frequency-converted to said third center frequency f3. Furthermore, the invention is applicable to general integrated-circuit processes as well as various ESD protection devices. The advance groove and the retard groove are spaced apart from each other along a longitudinal axis of the housing.
