Abstract: A method of stopping vibration of a columnar work during processing thereof, includes the steps of providing a cylindrical columnar work having an outer circumferential surface divided into a non-processed region and at least two recessed processed regions with a circumferential cross-section forming a perimeter including two spaced apart non-processed perimetric segments separated by two spaced apart processed perimetric segments, providing a vibration stop including only two holding parts having arc shaped surfaces, locating the columnar work between the arc shaped surfaces of the holding parts adjacent the perimeter with each processed region radially inward, orienting the columnar work such that each arc shaped surface contacts the outer circumferential surface at both spaced apart non-processed perimetric segments with one processed perimetric segment located therebetween, each arc shaped surface, and holding the columnar work with the holding parts to prevent vibration of the columnar work during proces

Abstract: A tail stock moving mechanism, in which a tail stock that holds a work with a predetermined pressure force is moved by a ball screw and in which control required for holding the work with the predetermined pressure force is implemented, is accomplished in a predetermined order wherein, the tall stock 1 holds a position of the work 5 and is supported by a ball screw 2, torque generated by a drive motor 3 that drives the ball screw 2 is detected, and when the torque reaches a predetermined reference value, then operation of a brake 4 to limit rotation of the ball screw 2 and cutting off of an input from a power supply to the drive motor 3 are performed.

Abstract: An object of the present invention is to provide a configuration of a vibration stop device that can prevent a problem caused by intrusion of a pressure contact region of a holding part of the vibration stop device into a recess of processing region of a work. The object can be achieved by the vibration stop device, in which a plurality of holding parts for vibration stop holds an outer circumferential surface of a columnar work in a process stage under a pressure contact state with pressure supplied from a hydraulic cylinder, and a pressure contact position on the outer circumferential surface is changed by rotation of the work, wherein an angular range formed by both ends of each of the holding parts for vibration stop is larger than an angular range of the processing region regarding an angular range based on a position of an axis of the rotation.

Abstract: In accordance with the present invention, the gate length and the gate insulation film thickness are different between the p-channel MOS field effect transistors serving as the driver gates and the n-channel MOS field effect transistors forming the flip flop. Namely, the p-channel MOS field effect transistors serving as the driver gates have a larger gate length and a smaller gate oxide film thickness than the n-channel MOS field effect transistors forming the flip flop.
