Abstract: PURPOSE:To form a secure nugget near the central part of a lap width and to prevent the generation of splashes at side edge parts by using electrode wires each having a convex lens-like sectional shape having a thick-walled part to the center of the width of the position adjacent to the center. CONSTITUTION:A pair of electrode rollers 1a, 1b are provided with hollow grooves 8 having the recessed surface corresponding to the sectional shape of the electrode wires 10 on the respective outside peripheries. The electrode wires 10 are tightly fitted into said grooves. The centers of the wires 10 are aligned to the center of a lap seam 3 and the joint edge of a can body consisting of a tin plate, etc., is welded. The lap seam 3 welded in the above-mentioned manner has the max. point of the quantity of the electricity to be conducted and the quantity of the electricity to be generated at the intersected point of the center line YY connecting the transverse centers of the upper and lower convex lens-shaped electrode wires 10 and the joint surface 9 of inside and outside blanks 2. The secure nugget 4 is thus formed. Projecting iron 5 appear at the side edges on both sides of the lap seam 3 but the generation of the splashes is decreased and therefore, the mending after welding is easy.

Filed: 1988-05-06
Abstract: PURPOSE:To certainly strip off a photosensitive material and image receiving material carried without wrinkles by causing the 2nd carrying rollers to carry the materials faster than the 1st carrying rollers. CONSTITUTION:This stripping-off device is constituted of a pair of 1st carrying rollers 56j, a stripping-off pawl 110 which is provided on the downstream side of the rollers 56j and pushes the photosensitive material A or image receiving material C carried through the rollers 56j toward one of the rollers 56j, and two pairs of 2nd carrying rollers 56r and 56s which are provided on the downstream side of the pawl 110 and respectively carry the materials A and C in different directions. The 2nd carrying rollers 56r and 56s are driven so that they can carry the materials A and C faster than the 1st carrying rollers 56j do. Therefore, the leading edges of the materials A and C are carried faster than the tailing edges of the materials after stripping off. Accordingly, the photosensitive material A is certainly carried and stripped off with no wrinkle which tends to be produced due to the load of the stripping-off pawl 110.

Abstract: PURPOSE: To reduce the displacement of a head, at the time of a change in regenerated tape speed ratio, to a needed and irreducible value, by making a decision on the track jump of a helical scan rotary head under fixed conditions.  
     CONSTITUTION: On a boundary line where ratio (n) of the regenerated-tape speed to the recording tape speed and head displacement P at a position of (d)% from the initial point of a track satisfy a condition expressed by formula I at the time of regeneration, a fly-back pulse voltage is determined corresponding to a small jump and large jump, depending upon whether displacement P of the head at the terminal point of the track is in a region above or below the boundary line. Then, shifting the head through a bimorph plate causes the head to jump to another track corresponding to the regeneration speed change ratio with the needed and irreducible displacement and, in consequence, the wear of the head is reduced, so that response deterioration in regeneration can be prevented.

Title: Atomic force microscope and adjusting method for irradiation position of laser beam
Inventor: FURUKAWA YUTAKA
IPC: G01N37/00
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To easily adjust the position of a laser beam by installing a display which displays that a quantitiy of light incident on a photodetector from a cantilever-type detection part (a cantilever) is a quantity of light which can measure the uneven image on the surface of a sample. SOLUTION: A display which displays that a quantity of light incident on a photodetector 24 from a cantilever 1 is a quantity of light which can measure the uneven image on the surface of a sample S. In order to adjust the position of a laser beam L, an irradiation-position adjusting mechanism 4 is operated while the display is being observed after the display has performed a prescribed display, the adjusting mechanism 4 is operated again while the tip of the contilever 1 is being observed under a magnifying microscope, and the position of the laser beam L is adjusted in such a way that the tip part of the cantilever 1 is irradiated with the laser beam. Thereby, irrespective of whether a quantity of received light is maximum or not, the position of the laser beam can be adjusted, and the position can be adjusted easily.  In this adjusting method, a high resolution cannot be obtained, but an operator who does not require a high resolution can observe the sample sufficiently.
