Title: Manufacture of waveguide
Inventor: FUJIMOTO MANABU
IPC: G02B6/13
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To uniformalize the dimension and the shape of the cross section of a core, even in the case of changing the light advancing direction of the core part of a waveguide by wiping a part of a groove in the different direction at a fixed angle, at least once by a squeegee. SOLUTION: Monomer 4 or a core material on a surface of a clad substrate 1, in which a groove to become a core of a waveguide is so formed as to have not a straight but a bending part in its midpart and include an (a)-directional part and a (b)-directional part, is wiped out by a squeegee 2 or 3. That is to say, when a core material is dripped on the surface of the clad substrate 1, it is wiped parallel to the A direction, namely, the (b)-directional part of the groove and then wiped in the B direction, namely, the (a)-directional part of the groove. When the wiping direction of the squeegee and the groove are in a parallel relation, namely, when the squeegee angle is 0 deg., the filling rate becomes 36%, and when the wiping direction of the squeegee and the groove are in the vertical relation, namely, when the squeegee angle is 90 deg., the filling rate reaches 100%.

Abstract: PROBLEM TO BE SOLVED: To attain improvement in the symmetry or magnetic flux density of magnetic flux distribution in a magnetic gap. SOLUTION: As shown in (a), the top end side of a center pole 23 is protruded from the surface of a plate 25 in a magnetic gap 21 of a magnetic circuit 20 and a protrusion quantity (h) is equal to a radius of curvature R of roundness at the top end of the center pole 23. As shown in (b), the magnetic flux distribution in the magnetic gap 21 is lowered on the top end side and base end side of the magnetic gap 21 while since the center pole 23 is protruded on the top end side and the radius of curvature R at a peripheral edge is equal to the protrusion quantity (h), an interval between an outer peripheral surface 24 of the center pole 23 and an inner peripheral surface 27 of a hole 26 on the plate 25 in the magnetic gap 21 can be fixed.  Thus, concerning the magnetic flux distribution in the magnetic gap 21, uniformity is improved and symmetry between top end side and base end side is improved as well.

Title: Checking devide for laser welding
Inventor: MORI KEIJI
IPC: B23K26/21
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To enhance checking accuracy in a checking device for laser welding. SOLUTION: With this device, welding conditions of plural metallic plates are checked from a color tone on the other side of plural metallic plate polymers 1, to which lasers are radiated from one side A. On the other side of the polymers 1, whether laser welding is correctly performed or not is checked by a degree of occurrence of a portion where the color tone is changed. In this case, not the condition of a welding mark 7 is checked, but a peripheral portion where the welding mark 7 does not occur is checked. Thereby, checking is stabilized. As a result, checking accuracy of the laser welding condition can be heightened.

IPC: B22D11/00
Filed: 1988-02-05
Abstract: PURPOSE:To cast an oil free twin roll by feeding the Al-Mg alloy molten metal whose Mg contg. amt. is more specified value between specified shall thickness rolls and casting an Al-Mg alloy plate by cooling the molten metal by a roll without coating a lubricant. CONSTITUTION:A pair of rolls 1, 2 are of the cylindrical shape having 35-60mm shell thickness (t) and the cooling member 3 circulating a cooling water is fixed onto the cylindrical face thereof. A cylindrical nozzle 4 is arranged at the upperstream side in the turning direction of the rolls 1, 2. The molten metal 5 of the Al-Mg alloy whose Mg contg. amt. is >=3.5wt.% is poured between the rolls 1, 2 via the nozzle 4 and solidified by cooling it by the rolls 1, 2 to obtain a casting plate 7. A solid-liquid coexisting phase exists between the molten metal 5 and casting plate 7. The Al-Mg alloy molten metal is cast by oil free without coating a lubricant on the shell outer peripheral face of the rolls 1, 2. The ununiform cooling due to this coating unevenness is eliminated because of no lubricant being used and the surface defect of the casting plate can thus be prevented.
