Title: Method for driving ultrasonic system to improve retention of blade resonance frequency in starting
Inventor: FRIEDMAN ALLAN L
IPC: A61B18/00
Filed: 2001-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for driving an ultrasonic system to improve retention of resonance of a hand-piece/blade in starting. SOLUTION: The resonance frequency of the blade to which heavy load is applied in starting is swept, and the capability of the ultrasonic wave system for locking to sweeping is improved by feeding high driving voltage or high driving current while the level of a feed signal is systematically heightened. The driving signal to the hand-piece is increased to obtain improved and clarified impedance spectrum. That is, in loading, the increased driving signal is further heightened in the maximum phase margin to further clarify the magnitude of the minimum/maximum impedance. In starting, an excitation driving signal to the hand-piece/blade is increased to thereby remarkably relax a limit factor of an ultrasonic generator, so that the maximum load in starting can be increased.

IPC: G06F13/36
Filed: 2001-10-25
Abstract: PROBLEM TO BE SOLVED: To improve transmission efficiency of a bus by allowing, even lead requests with burst lengths exceeding a buffer capacity (number) of a target device to output burst outputs, without inserting a wait. SOLUTION: A DMA control part 33 of an initiator 3 makes lead access request via a PCI (Peripheral Component Interconnect) bus 1, a control part 23 of a memory target device 2 which has determined that the lead access requests are made to the control part 23 itself stores lead data from a memory 4 into an inner buffer and executes burst transmission from the inner buffer. The memory 4 can transmit only a predetermined number at one time, due to boundary and deasserts inner access permissions, when the lead data is transmitted but maintains assertions of inner access requests. Then the lead data can be transmitted concurrently with the inner access permissions, when free space is generated in the inner buffer during the burst outputs and output the burst outputs with burst lengths exceeding the buffer capacity.

Title: Method and apparatus for manufacturing bolt
Inventor: KURIYAMA MASAE
IPC: F16B39/282
Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To increase the working degree in a method and an apparatus for manufacturing a bolt having a flat plate-like seat plate at the other end of a shaft having threads formed at one side. SOLUTION: The apparatus for manufacturing the bolt comprises the flat plate-like seat plate provided at the other end of the shaft 3 having the threads formed at the one side. The apparatus further comprises a die 11 for heading which is energized by a coiled spring 19 to compress the other end of the shaft 3 made of a metal to thickly form the other end. The other end is formed further in the flat plate-like state and the threads 2 are formed at the one end of the shaft 3. Since the die is buffered by the spring 19 at the time of compressing, a plastically working speed can be decelerated so that a craze or the like is hardly brought about with the result that the plastically forming degree can be increased.  The other end of the shaft 3 is cold-forged, and hence even when a facility such as a heating furnace or the like is not necessary to hot work, the working degree can be increased.
