Title: Estimation method of strength of spot welding operation
Inventor: ERIGUCHI TORU
IPC: G01N27/20
Filed: 1995-03-16
Abstract: PURPOSE: To obtain an estimation method in which a welding strength in a spot welding operation can be estimated nondestructively and with good accuracy by a method wherein a correction constant is found on the basis of an electrode displacement amount caused by the expansion of an electrode tip diameter in the case where welding intensities estimated from electrode displacement amounts measured by an electrode displacement sensor are nearly identical and on the basis of an interelectrode resistance. CONSTITUTION: In a spot welding part, electrodes 2 come into contact with surfaces of steel plates 1, and the boundary between the steel plates 1 in electrified parts is heated and fused. A nugget 3 is expanded by an electrified heating operation, and every electrode 2 is pushed up by a stress pn. Every electrode 2 is pushed by a pressurization force Fe in such a way that it comes in contact with every steel plate 1 in every contact area Se, and a stress Pe is applied to every steel plate 1 from every electrode 2. An electrode displacement amount (d) due to the strsses Pn, Pe is expressed by d=c(Pn-Pe)=α-γR, where α and γ represent correction constants, R represents an interelectrode resistance and (c) represents a constant.  The correction constants α, γare found by the method of least squares by using pieces of data on the displacement amount (d) and on the interelectrode resistance R in case where a welding strength at a welding initial stage and that at a welding later stage are equal. The tensile shear strength of a spot welding operation is estimated on the basis of a corrected electrode displacement amount.

Title: Lightweight banking structure
Inventor: YASUNO TAKEO
IPC: E02D17/18
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To improve stability of a banking structure by making a foaming plastic block used for at least one layer containing a hollow lowest bottom part, that of higher density than a foaming plastic block used for an upper part thereof. SOLUTION: According to sharpness of inclination of a rear surface inclination place 2, a banking structure has a high and large scale in the case of the same widened width, and a sliding force is liable to occur more downward in the inclination direction of the rear surface. In this case, the sliding force acts as a compression force on a foaming plastic block 1 and a large compression stress acts dovmward so that a lowest layer in section of the block 1 receives a largest compression force. A high density foaming plastic block 1b is therefore used in one layer containing a hollow lowest bottom part between a front surface wall 3 and the rear surface inclination place 2 so as to cope with the copression caused by the sliding.  It is prefarable that the density of the block 1b is not less than 22 kg/m and a polystylene foaming body exellent in strength and water resistance is used therefor. Accordingly, generation of large plastical deformation can be prevented.

If three kinds of carbon raw materials are used, the grain size is successively adjusted to give a higher grain size to a raw material having lower puffing property. The resultant blended raw materials are used to produce an artificial graphite electrode. Thereby the aimed artificial graphite electrode having both properties of low thermal expansion and low puffing is obtained by an extremely simple method and the production can be carried out by hardly reconstructing the existing equipment.

IPC: B61F5/06
Filed: 1995-03-20
Abstract: PURPOSE: To make natural frequency lower for reducing vibration transmissibility by lessening the apparent spring constant of a main spring used for absorbing the vibration. CONSTITUTION: A precise measuring device 1 having an aversion to vibration is supported on an installation floor 3 through a coil spring 4. A link device with spring 7 composed of a quadrilateral link mechanism 10 and a pair of fixed load tension springs 11a, 11b to connect the diagonal points of the mechanism 10 is provided parallel to the coil spring 4 inside that spring 4. The link device with spring 7 is adjusted so as to turn into an equilibrium state when the coil spring 4 is at a balanced position.
