    摘要： Disclosed is a process of producing a porous metal body containing a metal component which is likely to be oxidized, by which process the amounts of residual carbon and residual oxygen therein are decreased, and by which the performance of the product porous body can be largely promoted. The process for producing a porous metal body by sintering a material of the porous metal body, which material is obtained by coating a slurry containing a metal powder and an organic binder on an organic porous aggregate, comprises a defatting step of treating the material of the porous metal body at a temperature not higher than 650° C. in an atmosphere containing carbon monoxide and carbon dioxide; a decarbonization step of treating the material of the porous metal body after the defatting step in an inert atmosphere or vacuum atmosphere at a temperature not higher than sintering temperature; and a sintering step of retaining the material of the porous metal body after the decarbonization step in an inert atmosphere, vacuum atmosphere, hydrogen atmosphere, or in a reducing atmosphere containing hydrogen gas and an inert gas at a temperature not higher than the melting point of the metal powder.

    摘要： A fuel cell is disclosed having a water channel and a polymeric material contained in the water channel which minimizes freezing of water in the channel at sub-zero temperatures. Embodiments including attaching a thermo-responsive polymer such as an N-isopropyl acrylamide to the surface of the water channel to cause the thermo-responsive polymer to expand at low temperatures thereby reducing the propensity for water to freeze in the channel and also to cause the thermo-responsive polymer to contract at higher temperatures thereby preventing any restriction in the flow of circulating water in the channel.

    摘要： Before warmup of a fuel cell stack (1) is complete, a cooling water pressure of the fuel cell stack (1) is suppressed lower than the pressure used when the fuel cell system is run in the steady state. In this way, when the system is started from a low temperature state, water in a cathode (2) and anode (3) flows efficiently into the cooling water passage (9), and water clogging is prevented while maintaining a proper water balance in the fuel cell system.

    摘要： First and second guiding passages are defined in a ramp member. The first guiding passage extends along a first inclined plane intersecting with a reference plane by a first inclined angle. The second guiding passage extends along a second inclined plane intersecting with the reference plane by a second inclined angle larger than the first inclined angle. The first guiding passage serves to prevent collision between a recording disk and a head slider in a recording disk drive. The second guiding passage serves to enable a short-distance movement of the head slider on the ramp member. The boundary of a data zone can be located closest to the outer periphery of the recording disk.

    摘要： Methods are provided for complementarily dividing, on a divided stencil reticle as used in charged-particle-beam (CPB) microlithography, certain pattern elements into complementary pattern-element portions, and for exposing the pattern-element portions without significantly reducing throughput. For example, a large-area pattern element, having length and width equal to or greater than a division criterion L, is complementarily divided into linear pattern-element portions each having a width

    摘要翻译： 提供了用于在用于带电粒子束（CPB）微光刻中的分割模版掩模版上将某些图案元素互补地分成互补图案元件部分，并且用于暴露图案元件部分而不显着降低生产量的方法。 例如，长度和宽度等于或大于划分标准L的大面积图形元素被互补地分成各自具有宽度 = L的线性图案元素部分。 每个图案元件部分可以沿着沿着投影的部分结合在光刻基板上的边缘具有相应的重叠区域。 图案元件部分限定在至多两个互补的掩模版（或标线片部分）上，从而比传统方法对生产量施加较小的不利影响。 在其它实施例中，图案元素基于特定阻挡区域与图案元件的非阻挡区域的轮廓和形状分成互补图案元件部分。 图案元件被分割以减小尺寸误差，否则当投影到基底上时，在图案元件的拐角处过大的尺寸误差。 即，当尺寸误差超过预定公差时，则图案元素被互补分割。
