Title: Roller burnishing method and device thereof
Inventor: HAGA KATSUTOSHI
IPC: B24B39/04
Filed: 1986-12-24
Abstract: PURPOSE:To perform burnishing on the outer periphery or a work efficiently without leaving indentations by pressing the work rotated around an axis at the finish start position on oblique finishing rollers, starting the roller processing, and relatively moving it under the pressed state. CONSTITUTION:When finishing rollers 18 are brought into contact with a work 14 being rotated by a work drive device, the first and second roller units 70, 71 are expanded against the energizing force of a pressing device 64 because the outer diameter of the work 14 is larger than the distance between both finishing rollers 18 when a stopper 65 hits it. At the same time, the pressing between the work 14 and the finishing rollers 18 is started, the finishing rollers 18 and backup rollers 20 start to be rotated by the rotation of the work 14, a feeding device 22 slowly continues to feed a roller holding device 16, thus the pressing position between the work 14 and rollers 18 is moved in the axial direction. Next, as the pressing position is moved, the roller processing is applied to the whole outer periphery of the large-diameter section of the work 14 to obtain the predetermined smooth surface.

The diode bridge DB attains an off state, i.e., reverse biased state and the voltage value of the signal appearing at an input terminal Vin does not affect the hold capacitor CH any more and, therefore, the voltage value of the input terminal Vin at the moment when the strobe signal of the strobe terminal VS turns from H to L is held by the hold capacitor CH as the hold voltage value. The high-speed sample-hold circuit suitable for circuit integration is obtd. at a low cost in this way.

Title: Connecting device of wire end
Inventor: TSUZUKI CHOHEI
IPC: H01R4/50
Filed: 1988-12-09
Abstract: PURPOSE:To hold down the cost and obtain a connecting device of wire end with good workability by installing a wedge-type chuck which has an opening to expand when a wire end is inserted and increases in restraint after insertion. CONSTITUTION:When a worker operates an opening means to move a chuck means 13 in such a direction that the inside diameter of a tapered hole in a guide member 19 increases, an opening section 15A of a wire insertion inlet 15 is expanded. In this condition, the conductor (17) end of a wire 16 is inserted into an insertion hole 15 and an operation by the worker is released; thereupon, a means 13 moves due to an elastic force of a holding spring in such a direction that the inside diameter of the tapered hole becomes small. As the result, a restraint force is generated between the conductor 17 and the means 13; thereupon, the wire is temporarily held. When a tensile force is applied to the wire 16 in this condition, a wedge effect is produced between the means 13 and the tapered surface of the member 19 with the result that a restraint force increases and a wire connection portion which has a sufficient holding force can be obtained.

Abstract: PURPOSE:To perform the singular integration on a general curved surface at a high speed and with high accuracy by providing a means which performs the transformation of the variable in the radial direction so as to eliminate the singularity in the function and then integrating the function over the transformed variable in the radial direction. CONSTITUTION:Equation I shows the integration over a curved surface element S in a three-dimension, where (f) means a function containing no (quasi) singularity of a point (x) on the element S and (r) means the distance between a source point xs fixed the space and the point (x). In other words, a point x' is obtained on the element S nearest from the source point xs and the element S is approximately project ed to a polygon S' formed on the tangential plane at the point x' of the element S. Then a polar coordinate system centering on the point x' is introduced on S'. Then the singularity or the quasi singularity of the equation I is eliminated by a transforma tion for the variable in the radial direction together with the elimination of the quasi singularity in the argument direction by a transformation for the variable in the argument direction respectively. These converted variables are integrated for integra tion for the equation I. Thus it is possible to perform the singular integration produced by the boundary element method, etc., at a high speed and with high accuracy.
