Title: Method for determining crystal orientation of single crystal ingot
Inventor: USUI MAKOTO
IPC: G01N23/207
Filed: 1992-09-28
Abstract: PURPOSE:To discriminatingly determine a plurality of equivalent lattice planes by utilizing X-ray diffraction. CONSTITUTION:In order to determine crystal orientation of a <111> drawn Si ingot 28, a first X-ray detector 40 is placed in a plane perpendicular to a center axis Z1 of the ingot 28. A second X-ray detector 44 is placed in a plane gradient to the above plane. The detector 40 measures reflection from a {110} face, while the detector 44 measures reflection from a {311} face. When the ingot 28 is rotated once while X-rays are applied to an outer peripheral face of the ingot 28, the detector 40 observes six diffraction peaks while the detector 44 observes three diffraction peaks. By examining mutual positional relation between two systems of diffraction peaks, the six diffraction peaks originated from {110} can be classified into two kinds of lattice planes each containing three peaks.

Title: Arc spot welding method
Inventor: KITAHASHI YOSHIYUKI
IPC: B23K9/00
Filed: 1984-12-29
Abstract: PURPOSE:To improve the operating efficiency of welding by detecting the difference of the arc voltages between an electrode and an upper work and lower work in the stage of main welding and determining welding conditions in accordance with such voltage difference. CONSTITUTION:A welding power source 4 passes the prescribed main welding current between the work 1 and the electrode 2 upon receipt of the command from a controller 5. The potential difference of the voltages V1 and V2 between the upper work 1 and the lower work 1 and the electrode 2 is calculated successively by a CPU7 via an A-D converter 6. The welding conditions corresponding to such potential difference are drawn out of a memory 8 and are applied via an interface 9, sequence 10 and controller 11 to the welding power source 4. The power source 4 passes the crater current corresponding to the gap between the works 1 and 1 after a pause time according to the above-mentioned method. The optimum welding is thus made possible even if the gap between the works 1 and 1 changes and therefore the working efficiency is improved.

Title: Edge reinforced end mill
Inventor: SHIMA NOBUHIKO
IPC: B23C5/10
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To exhibit the natural performance of a wear resisting and oxidation resisting film and reinforce the cutting edge of an end mill by partially removing at least the film of a cutting edge part where the face and flank are crossed after covering. SOLUTION: Two-blade square type twist end mill (made of ultra fine particle cemented carbide) is covered with a laminated coating of TiN-TiAlNO by ion plating, and its cutting edge part where a face 2 and a flank 3 are crossed is circularly chamfered by use of a brush. The coating layer structure is formed of a two-layer structure, for example, consisting of a first layer of TiN and a second layer of TiAlN. When the thickness of the coating layer is 0.2 μm or less as the whole, the effect is small, and the coating layer is apt to peel with 20 μm or more. Accordingly, the wear resistance and oxidation resistance are improved to prevent the face crater damage caused by that a cutting edge such as ball end mill is nonlinear and apt to be concentrated.

Abstract: PROBLEM TO BE SOLVED: To carry out the smooth settlement of an underground construction and reduce costs by setting sheets at substantially constant distances from the outer circumferential surface of an underground construction to be settled, and filling skids having low circumferential friction force into a space defined between the sheets and the circumferential surface. SOLUTION: Each magazine 2 is arranged on an projection expanded in the radial direction from the outer circumferential surface 9 of a caisson (underground construction) 14, and a roll with a sheet 6 comprising a thin steel plate wrapped therearound is accommodated therein. The sheet 6 is delivered successively with the settlement of the caisson 14, and then skids 12 having low circumferential friction force is poured into a space defined between the outer circumferential surface 9 and the sheets 6. Since the caisson 14 never come in direct contact with the earth by means of the skids 12, its circumferential friction force lowers, so that the caisson 14 is not required to have steel material or the like placed thereon; thus, settlement and excavation are executed simultaneously through its deadweight.  Also, a press-fitting machine is not necessary in particular; which caisson settlement can be done without vibration and noise, and its execution can also be made possible in the neighborhood of a residential area.
