摘要： A manufacturing method of monolithic integrated thermal bubble inkjet print heads and the structure for the same. The method utilizes semiconductor manufacturing technologies to configure various elements in a thermal bubble inkjet print head, such as ink channels, an ink slot, an energy transducer, an orifice plate, on a single substrate. The ink channels are formed on an top surface of the substrate using the anisotropic etching technique. The ink slot is formed on a back surface of the substrate using the anisotropic etching technique. The energy transducer and the orifice plate are formed in order above the ink channels using the coating and etching techniques. This thermal bubble inkjet print head manufacturing method is particularly useful in the all batch process without employing the steps of precision alignment joint for the orifice plate in a conventional inkjet print head. Therefore, the method can greatly increase production efficiency and lower production costs.

摘要： An ink print head has an ink container for storing fluid, a chip installed at a bottom of the ink container having a central slot for passing fluid, and a dry film formed on the chip having a plurality of ink chambers. The ink print head also has a nozzle plate formed below the dry film, a middle portion of the nozzle plate protruding above the nozzle plate so as to form a central refill chamber, a plurality of nozzles corresponding to the ink chambers of the dry film, and a plurality of heaters set on the chip for heating fluid inside the ink chambers so that the fluid can be ejected from the nozzles of the nozzle plate. The fluid inside the ink container will flow through the central slot into the central refill chamber and then into the ink chambers.

摘要： To install a hard disk drive in a portable computer base housing, an upwardly opening well area is formed within the base housing and is sized to closely receive the disk drive. An electrical connector projects horizontally inwardly through one end of the well area and is operatively mateable with a corresponding connector on the front end of the disk drive. A flexible lowering strap is secured to the rear end of the disk drive. To install the disk drive, its front end is lowered into the well area while holding the strap to keep the rear end of the disk drive elevated. The strap is then used to controllably lower the balance of the disk drive into the well area to prevent installation shock to the disk drive that might occur if it were simply dropped into the well area. The lowered disk drive is then slid along the bottom of the well area to mate the well area and disk drive connectors. A clamping bar member is then extended along a rear top end portion of the installed disk drive and used to hold the disk drive firmly against the bottom side of the well area, thereby rigidly coupling the installed disk drive to the balance of the base housing in a manner eliminating the necessity of a separate shock and vibration isolation apparatus for the disk drive.
摘要翻译：为了将硬盘驱动器安装在便携式计算机基座壳体中，在基座壳体内形成向上开口的井区，并且其尺寸被设计成紧密接收磁盘驱动器。电连接器通过井区的一端水平向内突出，并且可操作地与盘驱动器的前端上的对应连接器配合。柔性降低带固定到磁盘驱动器的后端。要安装磁盘驱动器，将其前端降低到井区，同时握住磁带，以保持磁盘驱动器的后端升高。然后，该带用于可控制地将磁盘驱动器的平衡降低到井区域，以防止如果将其简单地落入井区域则可能发生的磁盘驱动器的安装冲击。然后，下降的磁盘驱动器沿着阱区域的底部滑动以与阱区域和盘驱动器连接器配合。然后，夹持杆构件沿安装的盘驱动器的后顶端部分延伸，并用于将盘驱动器牢固地保持在井区的底侧，从而将安装的盘驱动器刚性地联接到基座壳体的平衡消除了用于磁盘驱动器的单独的冲击和隔振装置的必要性。
