Title: Wire for welding having excellent feeding property
Inventor: MATSUMOTO TAKEO
IPC: B23K35/00
Filed: 1985-04-18
Abstract: PURPOSE:To improve the feeding property of a wire by controlling the ratio between the average thickness of an intergranular oxide layer of a wire surface layer and average crystal grain size within a specific range in the stage of intermediate annealing. CONSTITUTION:The same charge samples of the wire subjected to the intermediate annealing are drawn randomly from plural points and the intergranular oxide layers viewed from the cross section are measured. The average value thereof is determined. The value A of the ratio between the thickness of the average intergranular oxide layers and the average crystal grain size is controlled in a >=0.4-<=1.8 range. The intergranular oxidation arises over the entire surface of the crystal boundaries when the value A exceeds 1.8 and therefore the intergranular oxide part has the more tendency to exfoliation in the stage of drawing. Oil film breakage arises during the wire feeding when the value A is <0.4. The value A is therefore controlled within the above-mentioned range and the wire feeding property is improved by making combination use of lubricating oil coating.

Abstract: PURPOSE:To eliminate the need for a camp-on setting again with the telephone set of a moving destination by setting a camp-on by means of the extension telephone set as the setting side of a camp-on setting object to be dialed in the middle of the camp-on setting. CONSTITUTION:The operator of a telephone set 2 in the middle of the camp-on setting dials the particular number of a camp-on reservation, a camp-on starting time and the number of an objective telephone set 4 of the camp-on setting.

Abstract: PURPOSE:To prevent mistracking and accurately track a real target by tracking a clutter with clutter position information obtained by comparing target position information with clutter prediction position information in a clutter area. CONSTITUTION:A clutter area decision part 5 outputs target position data Ri and thetai, received from a target data buffer 3, to a wake target correlation pat 4 when the target position data Ri and thetai are outside the preset clutter area or to a clutter tracking part 7 when they are inside the clutter area. A tracking part 7 compares the data Ri and thetai with clutter prediction positions Rcpi-1 and thetacpi-1 from a clutter tracking buffer 10, and outputs target position data Xi and Yi as a clutter to a clutter prediction part 9 when the difference is less than a reference value or the data Ri and thetai as a real target to the correlation part 4 when not. The prediction part 9 outputs a clutter prediction position, etc., obtained next according to the data Xi and Yi to the buffer 10. Consequently, even when the real target enters the clutter area, the clutter is accurately tracked in the clutter area and removed.

Abstract: PURPOSE:To aim at a V-drive adoption for a ship which fails to take a large-sized engine room in the stern, by setting up a clutch shaft at the upper side of an output shaft, and also an input shaft, which is tilted to the output shaft and one side of the ends is projected to the same direction, in the upper part, while making gears of both input and output shafts so as to be engaged with each other. CONSTITUTION:When a shaft coupling 30 at the rear end side of an input shaft 25 is set to the input side and a shaft coupling 42 at the one end side of a connecting shaft 41 is connected to the input side, power is horizontally transmitted to the input shaft 25 from the connecting shaft 41, and it is transmitted to a forward clutch shaft 13 as being bent in acute angle form obliquely downward in the rear between a driving gear 26 of the input shaft 25 and a driven gear 31 of the forward clutch shaft 13. Afterward, power out of an output shaft coupling 5 of an output shaft 2 is transmitted to a propeller 39 via a propeller shaft 37. Hereat since an intershafting distance be tween the output shaft 2 and the input shaft 25 grows large, even if an engine 40 is made to come nearer to a deceleration reversing gear 35, it will not interfere with a body case of the reversing gear and the output shaft 2 or the like, V-drive specifications are adoptable even in case of such a ship which fails to take a space of an engine room so largely at the stern.
