摘要:
A substantially tubular iron tip (5) that can be heated and that is extended vertically and a solder piece supply portion that supplies a first solder piece (Whl) and a second solder piece (Wh2) in which a layer of a flux (72) is provided within a tubular solder layer in this order from above into the iron tip are provided, within the iron tip, the solder pieces are erected such that on the first solder piece, the second solder piece rides and the heat of the iron tip is used to melt the first solder piece and the second solder piece such that the molten solder is supplied downward. In this way, it is possible to more reliably heat and melt the solder pieces in a posture in which they are erected within the iron tip.
摘要:
In a solder processing device (A) which includes: a substantially tubular iron tip (5) that can be heated and that is extended vertically; and a solder piece supply portion (2, 6) that supplies a solder piece (Wh) from above into the iron tip (5), and in which the heat of the iron tip (5) is used to melt the solder piece (Wh) such that the molten solder is supplied downward, the supplied solder piece (Wh) is forcefully brought into contact with the inner wall of the iron tip (5). In this way, it is possible to more reliably heat and melt the solder piece (Wh) by use of the heat of the iron tip (5).

A device and method for controlling light by wavelength in a device with a switch plane and a dispersion plane uses optics providing an imaging function in the dispersion plane, and a Fourier transform function in the switch plane, so as to enable crosstalk to be reduced
摘要:
A method of operating a pixellated liquid crystal spatial light modulator comprising: numerically determining a hologram cell pattern for a portion of the pixellated liquid crystal spatial light modulator (200), whereby the pattern provides a desired replay intensity distribution in a Fourier plane (202); writing the determined hologram pattern to one region of the portion of the pixellated liquid crystal spatial light modulator (200); illuminating (201) the portion of the pixellated liquid crystal spatial light modulator (200) whereby the desired replay intensity distribution is attained; numerically translating or scrolling the determined hologram pattern to form at least one shifted version of the pattern for said portion of the pixellated liquid crystal spatial light modulator (200); and writing the at least one shifted version of the hologram pattern to one shifted region of the portion of the spatial light modulator (200).
摘要:
Apparatus and methods are described for calibrating an optical system having a Spatial Light Modulator, SLM, the method comprising a comparison of: a phase and/or amplitude distribution of at least one beam incident on the SLM, this phase and/or amplitude distribution measured by means of phase modulating elements on the SLM; with at least one known feature of the beam.
摘要:
The present invention relates to methods for inhibiting cathepsin K activity in a mammal in need thereof comprising administering a nitric oxide donor compound having cathepsin K inhibition activity. The present invention also relates to methods for inhibiting bone resorption in a mammal comprising administering to a mammal in need thereof a therapeutically effective amount of such a nitric oxide donor. The present invention also relates to compositions comprising such a nitric oxide donor.
摘要:
In a process for the hydroformylation of alkanes, alkenes or trialkylboranes under supercritical or near-critical conditions, hydroformylation is effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near-critical reaction medium. Selectivity of product formation may be achieved by independently varying one or more of the temperature, pressure, catalyst, mole ratios of hydrogen and carbon monoxide and flow rate.

摘要:
A curing agent for an epoxy resin based coating composition comprises at least one polyfunctional carboxylic acid having not less than three carboxyl groups together with a nitrogen containing accelerator, provided that, in the case where the accelerator is an imidazoline, the accelerator is not present as a salt of the acid.
摘要:
Un agent de polymérisation pour une composition de revêtement à base de résine époxy, comprend au moins un acide carboxylique polyfonctionnel comprenant non moins de trois groupes carboxyles ainsi qu'un accélérateur contenant de l'azote, à condition que, dans le cas où l'accélérateur ait une imidazoline, l'accélérateur n'est pas présent comme un sel de l'acide.
