  • Publication number: 20240072203
    Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.

  • Publication number: 20180256434
    Abstract: A McKibben type actuator capable of generating at least the same contraction force as that of the related art with an application of a pressure lower than that required for those in the related art is provided. In an McKibben type actuator 10 including an inner tube 11 configured to be expanded when being pressurized, and an outer sleeve 12 covering an outer peripheral surface of the inner tube 11 to limit an expansion of the inner tube 11, the outer sleeve 12 being configured to convert a radial expansion of the inner tube 11 to a longitudinal contraction of the inner tube 11, the inner tube 11 is formed of a resilient material having an expansion rate of at least 100%.

  • Patent number: 5282363
    Abstract: A hydraulic circuit for running a crawler vehicle which comprises a running frame portion provided with motors for running the crawler vehicle and an upper swivel portion turnably disposed on the running frame portion via a swivel joint. Electro-magnetic proportional flow directional control valve (a directional control valves) (15) for controlling the running motors are disposed between the swivel joint (41) and the running motors (19). The number of the high pressure passages in the swivel joint (41) can be reduced, because of increase of pressure resistance, the size of the swivel joint can be small, and accordingly, the hydraulic circuit for running a crawler vehicle can be inexpensive, and possibility for leakage of pressure oil becomes low.
