Abstract: A fat cutter and an integrated machine for preparation of in vitro fine-particle fat are provided. The fat cutter includes a fat inlet channel, a fat outlet channel, at least one set of blades disposed between an outlet of the fat inlet channel and an inlet of the fat outlet channel, and a housing that seals a space in which the outlet of the fat inlet channel, the inlet of the fat outlet channel, and the blades are located. A fat inlet of the fat inlet channel is connected to a large-diameter liposuction tube by a liposuction channel, and a fat outlet of the fat outlet channel is connected to a high-negative pressure device. The outlet of the fat inlet channel and the inlet of the fat outlet channel are oppositely provided, and a gap therebetween matches the thickness of the blades.

Abstract: An electronic device having an input control application is disclosed. The input control application is used for enabling the electronic device to execute the following actions: obtaining a member group comprising members lined up orderly and a member as a selection member; pressing a key to generate a first signal for excluding members after the selection member, then determining if only one member left in the member group, if “No”, determining the member of the member group in the middle as the new selection member, if “Yes”, executing the input operation; pressing another key to generate a second signal for excluding the members before the current selection member, then determining if only one last member in the current member group, if No”, determining the member of the member group in the middle as the new selection member, if “Yes”, executing the input operation.

Abstract: A method of manufacturing a light emitting diode (LED) includes growing a light emitting region on a temporary substrate, bonding a metal-coated reflective permanent substrate and then removing the temporary substrate. The reflective metal layer also serves as a bonding agent for bonding the permanent substrate. The bonded LED element and permanent substrate are heated in a wafer bonding tool that includes a graphite lower chamber and a graphite upper cover with a stainless steel screw. Because of the different thermal expansion coefficients between stainless and graphite, the stainless steel screw applies a pressure to the bonded structure during the heating process to assist the bonding of the permanent substrate.

Abstract: A method of manufacturing a light emitting diode (LED) includes growing a light emitting region on a temporary substrate, bonding a transparent substrate of glass or quartz to the light emitting region and then removing the temporary substrate. A metal bonding agent also serving as an ohmic contact layer with LED is used to bond the transparent substrate to form a dual substrate LED element which is then heated in a wafer holding device that includes a graphite lower chamber and a graphite upper cover with a stainless steel screw. Because of the different thermal expansion coefficients between stainless and graphite, the stainless steel screw applies a pressure to the dual substrate LED element during the heating process to assist the bonding of the transparent substrate.

Abstract: A module card retainer includes a base closure having two elongate side walls connected to two U-shaped end walls and defining a slot therebetween. Two clamping arms each have a central plate and two side plates pivotably connected to two side wall portions of the U-shaped end wall, respectively. Each clamping arm defines an inner channel between the central plate and the side plates. A seat is attached to each side wall portion of the U-shaped end wall. A locking member is retained in the seat and cooperates with a bolt to fix the seat onto a mother board.
