  • Publication number: 20250067254
    Abstract: A shape memory alloy (SMA) actuator can include an element (e.g., an SMA wire) configured to actuate when provided a current. The SMA element can be joined to the beam (e.g., made of stainless steel) using a resistance welding process that includes joining two metals by passing electrical current through them. A resistance welder, with smaller step sizes of power, lower total power, smaller step sizes of electrode clamp force, and lower time to time variability can produce additional test samples. Further, an approach can be taken to rebalance the heat of the system. The bottom electrode resistance (R6) can be increased by changing the electrode material from tungsten copper to a more resistive tungsten alloy. Further, a tungsten alloy can be used. The short duration pulse weld recipe with the higher resistivity bottom electrode can be the baseline resistance welding process for attaching SMA wire to stainless steel.

  • Publication number: 20240344505
    Abstract: The present embodiments relate to a shape memory alloy (SMA) actuator with a reduced number of materials for manufacturing the actuator. In some instances, elements of the SMA actuator can comprise a dielectric material disposed on the actuator via an injection molding process. In other instances, the SMA actuator can dispose SMA wires above a base of the SMA actuator without the use of any dielectric material. In a first example, an SMA actuator can include a carriage and a base. The base can include a fixed end fixed to the carriage, a free end, a beam connecting the fixed end and the free end, and at least one SMA wire. The SMA actuator can also include an insulator comprising a dielectric material electrically isolating a set of electrical contacts at the fixed end.

  • Patent number: 8051553
    Abstract: Apparatus for adjusting the static attitude of a head suspension having a gimbal with at least one gimbal arm. One embodiment of the invention includes a pair of first contacting members contacting a first side of the gimbal arm at a pair of spaced apart locations, and a second contacting member contacting a second side of the gimbal arm at an intermediate location between the spaced apart locations. The first and second contacting members move together relative to each other, plastically deforming the gimbal arm by the relative movement between the second and first contacting members while the spaced apart location between the first contacting members is maintained during the plastic deformation such that at least one of a pitch and roll parameter of the gimbal is adjusted to a desired amount.

  • Patent number: 7330338
    Abstract: Apparatus and method for adjusting at least one of a pitch and roll parameter of a gimbal for a head suspension assembly having a pair of members contacting at least one gimbal arm at spaced apart locations and having an additional member contacting the gimbal arm intermediate the spaced apart locations and wherein the members move together to cause plastic deformation of the gimbal arm. A like apparatus and method may be used sequentially or concurrently on a second gimbal arm, and may have an inverted orientation with respect to the first apparatus.
