An electrospray ion source for a mass spectrometer capable of generating ions from samples dissolved in a solution comprises a capillary tube through which the said solution is pumped into a first chamber maintained substantially at atmospheric pressure and in which an inert gas is flowing in a direction counter to the flow of the solution, and a small orifice in the end wall of the chamber opposite to and aligned with the capillary. A high potential difference is applied between the capillary and the end wall so that the solution is electrosprayed into the chamber and ions characteristic of the sample are formed. These ions are desolvated to a controllable extent by the inert gas, which may also be heated to improve the efficiency of the process and increase the maximum permissible flow rate of solution. The ions so formed pass through the small orifice into a second chamber maintained at a reduced pressure, and into a mass spectrometer. Alternatively an additional pressure reduction stage can be included, so that the ions pass into a third chamber maintained at a still lower pressure in which the mass spectrometer is situated through a conventional nozzle and skimmer arrangement. The ion source is particularly effective for the production of unfragmented and unsolvated ions from thermally unstable or involatile samples, and may be used as a liquid chromatograph--mass spectrometer interface.

A method of changing the energy of charged particles contained in a gas comprises allowing the gas to flow into a region of reduced pressure through a tube like member so that viscous forces exerted on the charged particles by the flowing gas molecules determine the kinetic energy of the charged particles. A potential gradient is maintained along the length of the tube so that the potential energy of the charged particles is changed as they pass through the tube. At the end of the tube a free jet expansion occurs so that the kinetic energy of the charged particles is no longer determined by the flowing gas, so that they can be accelerated to any desired kinetic energy by means of another potential gradient.The invention can be used to interface any high pressure ion source to a magnetic sector mass spectrometer, or to permit the operation of an electrospray ion source with an earthed inlet capillary with either a quadrupole or a magnetic sector mass spectrometer.

There is provided a melt spinning apparatus capable of reducing the unevenness of fineness of a yarn. The nozzles of the spinning plate are arranged annular in at least one circle, and a cylindrical filter is disposed at an exit of a cooling wind in the cooling device so as to enclose around a spun yarn discharged from the spinning plate. The annular diameter of the nozzles is from no less than 0.6 times to no more than one time of the internal diameter of the cylindrical filter, and the flow velocity of the cooling wind blown from the cylindrical filter is distributed gradually higher according to the downstream of the spun yarn.

A document processing apparatus reads document data and carries out a preflight check. In the preflight check, the content of the document is interpreted page by page to determine resources that are needed for output. Then, it is determined for each page whether the resources needed for output are available in a printing system. If a resource that is not available is needed, a warning is issued for the page. If the resources are available, intermediate data for a printed output is generated for the page. Then, a result of the preflight check is output.

摘要:
A solar battery module has a structure in which a solar battery cell formed by a transparent electrode, a power generating element, and a back electrode is formed on a substrate, and it is sealed with a resin material such as EVA. However, there has been a problem that water enters from a gap between the substrate and a resin sealing material, thereby resulting in the corrosion of the resin or the solar battery cell. A barrier layer made of inorganic substances having portions in contact with the substrate and the second electrode is provided. Here, the barrier layer is formed by laminating at least SiO2 and an inorganic layer having a lower density than SiO2, and the film having a lower density than SiO2 is directly formed on the substrate and the second electrode.
