A pulse forming circuit for a vibration type actuator apparatus. This circuit forms pulses by shifting an output from a frequency dividing circuit while changing the shift amount of a time delaying circuit using a ring oscillator for shifting an output from the frequency dividing circuit every time an output is generated by a frequency dividing circuit. With this arrangement, the actuator can be driven by using high-resolution pulse signals.       Recently Added Patents Crosstalk cancellation for a common-mode channel Electro-optical device and electronic apparatus Asymmetric coil spring Connection management system for multiple connections Card reader terminal Filter cigarette Nonaqueous electrolyte solution and lithium secondary battery using same   Randomly Featured Patents Circuit and method for protecting motherboard Memory shared between processing threads Connection assembly for spinal implant systems Memory system having magnetic disk drive implemented as cache memory and being integrated with optical disk drive in a hierarchical architecture Light on a stick Security bars and barrier grids incorporating same Apparatus for the continuous desublimination of vapors of subliming substances Pultrusion method for condensation resin injection Coding system for an alarm system and the like Prediction apparatus for predicting based on similar cases and method thereof © 2006-2008 PatentGenius.
