Abstract in simplified Chinese:本发明揭示使用薄膜沸腾制程改善多孔基材密实化之方法及设备。具体而言,所揭示方法及设备借由提供一种降低待密实化基材表面冷却之屏障以允许基材更完全密实化(即更靠近该基材表面之密实化),该冷却系借由与所密实化材料(例如碳)之相对较冷沸腾液态前体接触而达成。具体而言,使用物理屏障(例如筛网材料)或可在该基材与该液态前体间促进形成隔离气体层之结构(例如距离多孔基材表面较近间隔之板)之一或二者来减少基材与液态前体之间之接触。
Abstract in simplified Chinese:一种用于馈给一气体至一炉、熔炉或其类似物(例如CVI/CVD炉)中,且尤其系馈给一气体至该炉内部之一反应室结构(16)中之管道(12)具有一气密管状密封设备(32),该密封设备在该管道外部径向延伸且界定一实际上的气密路径,该气体馈给管道沿该路径延伸。该管状密封设备较佳地为在横向方向及/或轴向方向上至少部分可挠,以便适应在该反应室内之一位置与气体馈给管道穿入该炉所经由之一置置之间的定位缺陷(该等缺陷可能系由于例如不对称热膨胀/收缩)。
Abstract in simplified Chinese:在制造方法,如致密化,期间由穿孔金属材料制造的一件式或单一环状分隔片组件被用于维持堆栈环状预成型体物间的空间。所使用金属材料较佳为能耐至少在致密化期间遭遇的温度。该一件式结构有利地简化该预成型体在加工室的排列及引起在该预成型体的较少变形。在一个实例中,该分隔片组件系由金属网制造及使用卷曲纹织结构。
Abstract in simplified Chinese:一种由碳材料制成的单片或其他单元环形分隔片组件用于在制程(如致密化)期间保持堆栈的环形预型件间之间隔。单片式结构有利在处理室中简化预型件之布置,并产生较小预型件变形。碳组合物亦提供改良致密化制程的有利热效应。为便于自分隔片组件分离环形预型件,在环形分隔片组件上提供剥离涂层。
Abstract in simplified Chinese:本发明揭示一种制造纤维预成型之方法,其尤其系借由针织纤维材料(例如,沥青基或PAN基不连续纤维)而达成。本发明提供一种针可刺入模板(10),其中具有至少一用于收纳纤维材料之模穴(12)。针可刺入模板之使用允许其中具有纤维材料之模板随意地穿过线性针织设备,例如线性针织机,而不必如习知技术那样严格地小心限制至不连续纤维材料之针织路径。相对于针织设备移动模板一或多次直至达到所要程度之材料密度(有时借由纤维含量百分比来量测)。较佳地,沿一通常与模板移动之方向横向的方向相对于针织设备额外地移动模板及/或使其移动,以避免针"迹"之习知问题,且借此产生更好的针织效果。

PROBLEM TO BE SOLVED: To reduce the vibration generated by electromechanical brake without making its structure complex and without increasing its weight or cost.SOLUTION: The invention relates to a braking method for an aircraft having at least one electromechanical brake 2 fitted to at least one braked wheel of the aircraft. The brake 2 has friction members 3 and a plurality of electromechanical actuators 4. Each actuator 4 includes a pusher 5 suitable for being moved by an electric motor 6 to selectively apply a pressing force on the friction members 3. According to the invention, for a given braking operation, a total braking force to be applied against the friction members 3 of the brake is distributed in a non-uniform manner among the actuators 4 of the brake such that at least two actuators 4 apply respective different forces.
Abstract:
The actuator has brake units (106, 110) e.g. magnetic braking units, to brake sliding of an auxiliary rod (20) in a main rod (2) in an extension direction. The auxiliary rod comprises a thread (101) on an outer surface. The main rod has an end carrying a rotary bearing (102), which centers the auxiliary rod in the main rod and co-operates with the thread via a reversible helical connection such that extension of the auxiliary rod causes the bearing to rotate. The brake units brake the rotation of the bearing during extension of the auxiliary rod.
Abstract:
The device has a hydraulic block (1) receiving a removable hydraulic filter (2), where the filter is screwed in an inlet of an internal thread (8) of the hydraulic block. The block has a clamp (101) for axially retaining the filter, when the filter is screwed on the hydraulic block. The block has a base coaxial to the inlet of the thread. A nut (102) fixes the clamp on the hydraulic block and is screwed in a base of the thread. The clamp has a base supported on a shoulder of the block.
