A computer-implemented method includes identifying a representation of a feature of an animated character by inverting an skinned representation of the feature in one position. The mold includes an upper surface, and a lower surface having an outer peripheral surface and a concave surface surrounded by the outer circumference. There is provided a function of relieving a synchronization determination condition if the synchronization establishment is not detected in any of the synchronizing detection circuits, whereby the output from the proper logical operation circuit can be selected depending on a load on a transmission path. They may yield if an excessive torsional load is experienced, and may be supplied in various interchangeable forms for fitting to a given block so that its characteristics may be adjusted. This avoids a deadlock situation and allows the device to remain operative even in partial recovery situations. The nozzle insert is configured to form a reflux cell in the liquid supply channel upstream of the liquid supply channel exit opening to achieve flow blurring interaction between the liquid product and the gas propellant.
