Patent number: 11703076Abstract: A press-in fastener has from top to bottom: a head, a clinch feature, and a spiral, knurled shank. The fastener can hold two parts together by first clinching with a first metal panel, and then being pressed into a hole in a second, less ductile panel having a uniform interference between the knurled fastener shank and the hole. The knurled shank has a helix configuration that allows for use in non-ductile materials and eliminates the need for tapered holes and screws for applications that do not require disassembly.Type: GrantFiled: June 21, 2019Date of Patent: July 18, 2023Assignee: Penn Engineering & Manufacturing Corp.Inventors: Qiang Sun, Dapeng Duan, Larry Zhang

Patent number: 7551406Abstract: A recording head comprises a write element, including a coil and a dynamic fly-height heater, and two electrical lapping guides. The head also comprises a number of bonding pads including a DFH bonding pad and a shared bonding pad both electrically connected to the dynamic fly-height heater. Each lapping guide defines a circuit between the shared bonding pad and a dedicated bonding pad and each includes a resistive element. The resistive elements of the two lapping guides can be vertically aligned to be used to control a lapping tilt angle when a bar of unfinished heads is lapped. After lapping, a channel is defined into the transducer of the recording head. Forming the channel can remove at least a portion of each lapping guide in order to break the electrical circuit of that guide.Type: GrantFiled: April 28, 2006Date of Patent: June 23, 2009Assignee: Western Digital (Fremont), LLCInventors: Mark D.
