Abstract:
There is provided a method of manufacturing a vitreous body surgical probe that is easily manufactured and has a flat end outer surface and a flat end inner surface. A method for manufacturing a vitreous body surgical probe (10) includes the steps of: bringing a steel plate (30) in contact with an end surface of a steel pipe (20); and irradiating an energy beam (50) from the steel plate side along the outer circumference of the pipe end surface. The steel plate is cut through irradiation of the energy beam (50), and the pipe (20) and the steel plate (30) are welded together simultaneously. Alternatively, a step of using the same energy beam for cutting and welding the steel plate may be added.
Abstract:
The present invention relates to: a method for cutting a separation membrane for a battery, in which the separation membrane is cut by laser radiation on the separation membrane, wherein the pulse repetition rate of the laser is 10 to 500 kHz; a separation membrane manufactured by the method; and a battery comprising the separation membrane. The present invention, in contrast with physical cutting, has the advantage of being capable of cutting a separation membrane for a battery so as to have a uniform cut surface, which was impossible by conventional physical cutting methods.
Abstract:
An additively manufactured component is provided. The additively manufactured component includes an additively manufactured first part (11) defining a first trench, an additively manufactured second part (12) defining a second trench and a fiber optic sensor (13). The additively manufactured first and second parts (11, 12) are additively manufactured together with the first and second trenches corresponding in position such that the additively manufactured first and second parts form an assembled part with a fiber channel cooperatively defined by the first and second trenches. The fiber optic sensor (13) includes a first sensor part embedded in the fiber channel and a second sensor part operably coupled to the first sensor part and extendible at an exterior of the assembled part.
Abstract:
This invention relates to a laser soldering device (1) for laser soldering an electric circuit of a heating portion (100) of an electronic cigarette, the soldering device (1) comprising a laser soldering head (2) having an emitting area (3) where a laser beam (4) is emitted and a feeding device (5) configured to feed a heating portion (100) of an electronic cigarette along a feed path (P) at least as far as a soldering position, where the heating portion (100) faces the laser soldering head (2) at the emitting area (3). Movement means (6) are provided which are operatively connected to the laser soldering head (2) and which are configured to move the laser soldering head (2) between a first point and a second point of the electric circuit in such a way that the laser beam (4) is perpendicular to the respective surface to be soldered at the first point and at the second point to form a first connection and a second connection, respectively. The laser soldering head (2) comprises means for generating two distinct pulses of the laser beam (4) at the first point and at the second point.

[Object] To provide an Au-Ag-Sn-based solder alloy for high temperature use that is so good at reflow wettability as to be sufficiently usable in reflow bonding of crystal quartz devices, SAW filters and MEMS, wherein, in particular, the solder alloy costs low and is excellent in solderability, reflow wettability and reliability. [Measures for Solution] An Au-Sn-Ag-based solder alloy containing Sn, Ag, Au and elements that are inevitably contained owing to manufacture procedure, characterized by having a composition adjusted so that a solidus temperature is within a range of 280-400°C with a gap between the solidus temperature and the liquidus temperature being within 40°C.
Abstract:
The present application relates to laser welding methods, wherein an irradiation with a laser beam is started at a welding start position of two members that are stacked together, and the output of the laser beam is set so that spatter is not generated. After the start of the irradiation, the output of the laser beam is gradually increased so that a penetration depth from an irradiated edge to a deeper location between abutting surfaces of the two members falls within a predetermined penetration depth range while the laser beam is not moved. After the output of the laser beam is gradually increased, the laser beam is moved toward a welding end position so that the penetration depth is maintained within the penetration depth range.
Abstract:
An induction heater having inner and outer chamber cylinders connected in an air tight manner to a base and cover with an inner chamber being formed within the inner chamber cylinder and an outer chamber being formed between the inner and outer chamber cylinders, a heat exchange core disposed in the inner chamber, and an induction heater coil disposed in the outer chamber extending around the inner chamber cylinder. A flow path is provided from a cool air inlet in the base, along the outer chamber, into the inner chamber and through the inner chamber and core to a heated air outlet in the base in a counterflow direction relative to the flow along the outer chamber. The heater is especially well suited for use in convective soldering and rework apparatus.
Abstract:
A welding process (S1), which uses a welding device (1) that welds a welding object using a pulse laser, wherein a first light-receiving unit (20) receives only infrared rays having a wavelength that allows detection of the keyhole formed in the molten pool from among the infrared rays emitted from the welded portion of the welding object during welding and an analysis unit (40) assesses the quality of the welded portion on the basis of the intensity of the infrared rays received by the first light-receiving unit (20).
