摘要： An apparatus and method for automatically adjusting the gram load, static attitude and the flying height of the slider in a head suspension assembly comprising one or more lasers, a fiber optic switch, a measurement apparatus and a computer control device. The fiber optic switch includes a plurality of fiber optic lines which direct the output of the laser to well-defined regions on the suspensions in a disk drive. Irradiation of the suspension by the laser causes a load change which alters the flying height, and/or a static attitude change in the slider. In the method of the present invention, the initial gram load, flying height or static attitude of the slider is measured by the measurement apparatus and the control means calculates how much energy is required to cause the change needed to achieve the desired condition. Other information, such as the type of laser to be used is also specified by the control device. The laser then delivers output to the suspension through the fiber optic line and the static attitude, flying height, or gram load is remeasured to determine if additional adjustment is required.

摘要： A joining technique and design for welding hard to weld elements of a disk drive suspension machines or coins the parts to be welded at their weld interface. A small pocket is formed at the weld interface to let evaporated material gases escape during welding and reduce gas bubble trapping in the weld nugget. For laser welding, a pocket is formed in thick parts to control the welded web thickness for fast melting and thorough mixing of top and bottom materials. For resistance spot welding, it may be necessary to form pockets in both materials on the electrode contact side to reduce material thickness. This technique provides a weld interface design that solves joint reliability and dynamic variation problems. This technique can be used to attach aluminum-to-aluminum or other materials that are difficult to weld due to porous welds, and to improve weld quality of both spot and seam welds.

摘要： An MR head receives ESD protection from a mechanism that automatically and releasably shorts the MR head whenever a suspension assembly on which the head is mounted is not installed in an HDA. The suspension assembly includes a flexure underlying a load beam, which is connected to an actuator arm. The MR head is mounted to a distal end of the flexure, leads from components of the MR head being brought out in the form of MR wire leads running along the load beam and the support arm to a nearby terminal connecting side tab. The conductors are separated and exposed at a designated point along the flexure to provide a contact region. A shorting bar, which comprises an electrically conductive member attached to the actuator arm, automatically connects the MR wire leads at the contact region when absence of support for the MR head permits the load beam to bend sufficiently toward the shorting bar. Thus, when the assembly is removed from installation in an HDA, the flexure is permitted to move toward the shorting bar, bringing the contact region and the shorting bar in electrical contact to short the MR wired leads and thereby disable the MR sensor. When the assembly is installed in an HDA, the MR head is supported by an air bearing or the disk itself, depending upon whether the disk is rotating or stopped, respectively. In either case, the load beam is not permitted to droop and the shorting bar cannot contact the conductors, thus activating the MR sensor. Temporary ESD protection mechanisms are also provided, these being removable prior to operation of the HDA by breaking and removing various temporary shorting mechanisms.
摘要翻译：每当安装有头部的悬挂组件未安装在HDA中时，MR磁头可以从机构自动和可释放地短路MR头部获得ESD保护。悬架组件包括连接到致动器臂的负载梁下方的挠曲件。 MR头被安装到挠曲件的远端，从MR头的部件引出的MR导线沿着负载梁和支撑臂延伸到附近的端子连接侧突出部的形式被引出。导体沿着挠曲件在指定点处分离并暴露以提供接触区域。包括连接到致动器臂的导电构件的短路棒在没有用于MR头的支撑的情况下在接触区域处自动连接MR线引线，允许负载梁朝向短路棒充分弯曲。因此，当组件从HDA中的安装中移除时，允许挠曲件朝向短路棒移动，使接触区域和短路棒电接触以缩短MR有线引线，从而禁用MR传感器。当组件安装在HDA中时，MR磁头由空气轴承或磁盘本身支撑，这取决于磁盘是分别旋转还是停止。在任一情况下，负载梁不允许下垂，并且短路棒不能接触导体，从而启动MR传感器。还提供了临时ESD保护机制，它们在HDA操作之前可以通过断开和移除各种临时短路机构来拆卸。

摘要： The invention comprises an accessory for use with a driver for forceably inserting friction rock stabilizers into bores formed in earth structures (such as mine roofs). In the depicted embodiments, the Accessory comprises an elongate body having a driver element with a pin or boss at one, lower, "driven" end of the body for engaging and supporting an end of a stabilizer, and a second driver element with a socket, at the opposite, upper, "driving" end of the body for receiving an insertion tool. The latter driver element can be pivotably offset, to accommodate an angled, unobstructed address of the insertion tool to the upper end of the body, and to enable a linear insertion of a stabilizer, supported on the lower end of the body, into a bore. In accommodating a driver at the upper end of the body, to forceably insert a stabilizer which has its termination supported on the lower end of the body (the insertion force, therefore, being applied through the body), the Accessory facilitates bore insertion of lengthy stabilizers, by means of conventional tools, in low headroom, subterranean openings.

摘要： A hard disk drive suspension having a load beam with an original thickness of 4 mils (approximately 0.1 mm) is simultaneously etched on both sides in selected areas to approximately half of its original thickness. The selective partial etching makes intricate features which are otherwise unattainable by conventional forming operations. These features reduce the weight of the load beam and provide a very stiff structure when the etched features or pockets are enclosed in an extended, box-like fashion by a flexure and mount plate. The only press forming operations remaining are to generate a load/unload tab semicircular cross-section and dimple. This configuration more than triples the first torsion frequency from about 2 to 6 KHz or higher, thereby increasing the servo band width by a multiple of 3. Moreover, when the box-like portion of the suspension is replaced by milliactuator motors, the etched suspension meets the mass, inertia, sag, and servo bandwidth requirements with micro-actuation capability.
摘要翻译：具有原始厚度为4密耳（约0.1mm）的负载光束的硬盘驱动器悬架在选定区域的两侧同时蚀刻到其原始厚度的大约一半。选择性部分蚀刻使复杂的特征成为常规成形操作无法实现的。这些特征降低了负载梁的重量，并且当蚀刻的特征或凹穴通过弯曲和安装板以延伸的盒状方式封装时，提供非常刚硬的结构。唯一的压制成型操作是产生一个装载/卸载片半圆形的横截面和凹坑。这种构造使第一扭转频率大于约2至6KHz或更高，从而将伺服带宽度增加了3倍。此外，当悬架的盒状部分被毫米制电机代替时，蚀刻悬架满足微动作能力的质量，惯性，下垂和伺服带宽要求。
