    摘要: A tool holder, for mounting a bit formed with a groove onto a power tool, includes a tool-holding tool, an engagement member, and a resilient member. The tool-holding tube defines a bit insertion hole that extends in an axial direction. The tool-holding tube is formed with an elongated hole that is in connection with the bit insertion hole and that extends in the axial direction. The engagement member is disposed in the elongated hole and partially protrudes into the bit insertion hole. The engagement member is movable, by abutment with and pressing force from the bit being inserted into the bit insertion hole, in the axial direction and, when located at a retraction position in the axial direction, also outward in a radial direction of the tool-holding tube. The resilient member is disposed to an outer periphery of the tool-holding tube at the retraction position. The resilient member increases in radial dimension from an initial state by pressure from the engagement member moving outward by pressing force from the bit. The resilient member resiliently returns to the initial state when pressure from the engagement member stops because the groove of the bit is located at the retraction position. As a result, the resilient member presses the engagement member inward in the radial direction into engagement with the groove of the bit.

    摘要: The invention provides an apparatus, and a method, for detecting the tread profile of a tire mounted about an X-axis comprising a non-contact Y detection means movable in parallel to the X-axis for measuring the distance at a right angle between such means and the peripheral surface of the tread profile in the direction of the Y-axis, X detection means for detecting the position of the Y detection means along the direction of the X-axis, data memory means for storing X and Y data pairs obtained by both such detection means, and radius calculating means for calculating the radius of the article from the X and Y data stored in the data memory means. The radius calculating means includes division means for dividing the X and Y data for a plurality of portions of the tread profile based on predetermined reference values for the tread profile of the tire being measured and arithmetic means for determining the radii of the respective portions each from the corresponding data divided by the division means, the arithmetic means determining the circle equation of: x.sup.2 +y.sup.2 +ax+by+c=0, from the X and Y data to calculate the radius of the tread profile, the coefficients a, b and c of the circle equation being determined by least square approximation.

    摘要: A telephone exchange system useful for a bank or brokerage house speech system or the like, which can accommodate a large number of lines (or trunks) and permit improvement of the reliability and call connection processing capacity. The system comprises exchange sub-systems A (EX-A) and B (EX-B) capable of independently executing an exchange operation and each accommodating a terminal. The terminal, on the other hand, has a speech channel switch for connecting a speech channel including a handset to either exchange sub-system A (EX-A) or B (EX-B). When a process of connecting a call is brought about in the terminal, that terminal selects one of the exchange subsystems and controls the speech channel switch for connecting the call to the selected exchange sub-system.
