A suture anchor includes a threaded anchor body having a bore for receiving a driver, and at least two distal passageways extending from the bore to corresponding apertures at the distal end of the suture anchor. The apertures are provided as pairs with a corresponding groove formed between the apertures of the pair. Suture strands can be inserted into the suture anchor through the apertures, the distal portion of the sutures seated in the grooves between the apertures being protected from abrasion during installation of the suture anchor.

The invention discloses a plunger pump hydraulic end with long service life. The plunger pump hydraulic end comprises a valve box, a plunger, and a packing assembly; the valve box serves as a container for liquid conveying; the plunger is connected to the valve box through the packing assembly; the packing assembly comprises a packing component, a packing sleeve, a packing pressing cap, and a packing sleeve pressing cap; the packing sleeve is connected to the valve box in a sealed manner; the packing component used for sealing fills between the packing sleeve and the plunger; the packing sleeve pressing cap is used for fixing the packing sleeve; and the packing pressing cap is used for fixing the packing component. The plunger pump hydraulic end with the long service life has the beneficial effects that the service lives of the valve box, a suction pressing cover, a suction pressing cap, and a discharging pressing cap are prolonged through optimization design of each of the plunger, the suction pressing cover, and the suction pressing cap, thereby prolonging the service life of the plunger pump hydraulic end.

A shoelace reel includes a support seat, a spool rotatably mounted in the support seat, a shoelace having two distal ends each secured to the winding zone of the spool, a limit sleeve mounted on the support seat, a drive member rotatably and movably mounted in the limit sleeve, and a control knob rotatably and movably mounted on the limit sleeve and connected to the drive member. Thus, the user only needs to rotate the control knob to tighten the shoelace and to pull out the control knob to loosen the shoelace. In addition, the user only needs to operate the control knob to tighten or loosen the shoelace, so that the user can tighten or loosen the shoelace by his one hand only.

A wearable caddy for a personal audio device (PAD) adapted to mount at least one PAD and store excess earphone cord. The caddy comprises a front plate and a back plate joined by a plate separating member that creates a space between the plates adapted to store the excess cod by spooling the excess cord around the separating member. The PAD is mounted to the front surface of the front plate using a double-sided adhesive pad. A clear self-adhesive plastic cover is placed over the face of the PAD. More than one pad may be mounted to the same caddy. The caddy clips to the belt of the wearer and can be used to store earphone cord or heavier head-set cord.

The present invention relates to a hydraulic-transmission- braking three-use lubricating oil composition, which is prepared by mixing the following raw materials, by weight, 85-98% of high viscosity index base oil, 0.1-5% of an extreme pressure wear resistance agent, 0.1-4% of an antioxidant, 0.1-3% of a metal deactivator/antirust agent, 0.1-5% of a friction modifier, and 0.1-2% of a dispersing agent. The hydraulic-transmission- braking three-use lubricating oil composition has beneficial effects of good low temperature fluidity, friction reduction, wear resistance, corrosion resistance, rust resistance, emulsification resistance and foaming resistance, and can meet requirements of universal hydraulic transmission oil used by large-medium-sized tractors and construction machinery so as to achieve complete lubricating protection on hydraulic parts, transmission parts, gear parts, power output parts and braking parts, such that a long service life is provided, equipment operation stability is easily improved, and energy saving and consumption reduction are provided.

The invention discloses a method for preparing a bimetal composite plate by stirring friction braze welding. The method comprises that: a plate with small hardness is used as a covering layer metal plate; a plate with high hardness is used as a base layer metal plate; the covering layer metal plate and the base layer metal plate are horizontally fixed on a working platform surface in a lap joint mode; solders which can generate eutectic reaction with one of the upper/base layer metal plates are preset between the upper/base layer metal plates; a non-needle type cylinder friction device is arranged over the covering layer metal plate; the non-needle type cylindrical friction device is made to rotate and be pressed to be closely contacted with the surface layer of the covering layer metal plate, but not penetrate the covering layer metal plate, and the non-needle type cylindrical friction device rotates in the original position or moves forward along the surface of the covering layer metal plate while rotating; by utilizing frictional heat to melt the solders, the upper/base layer metal plates are both quickly melted in the solders, thereby achieving excellent interface combination; and the excessive solders are squeezed out, and a thin and dense soldering seam is formed, so that the bimetal composite plate is prepared. Compared with the braze welding in a furnace, the method has the advantages of high efficiency, energy conservation, pressure lead-in, unnecessary soldering flux and gas protection and short holding time at a high temperature.

A flash memory device with a wear-levelining mechanism includes at least one flash memory, a hot list, a bitmap, a source pointer, and a controller. The controller obtains a physical memory block with high erase count through the hot list, an erase count of the physical memory block, and an overall average erase count of the flash memory device. The controller further finds out a physical memory block which stores static data through managing the bitmap and the source pointer. The controller moves the static data to the physical memory block with high erase count, and releases the physical memory block which stores the static data to avoid the physical memory block with high erase count being worn down increasingly more seriously.

An optically clear encapsulant for optoelectronic packages exhibits a suitably high viscosity both to replace a silicon nitride passivation layer required on a VCSEL die and to fill a gap between the die and an optical coupler, preventing light signal degradation. The encapsulant exhibits optical transparency to light having a wavelength of about 850 nanometers (nm) with substantially no Mie scattering since particulate fillers are not required to modulate viscosity in the encapsulant. Also, the encapsulant further seals wire bonds between the die and a cable header to prevent abrasive wear. The gap-filling encapsulant is particularly suitable for use with vertical cavity surface emitting laser (VCSEL) technology. The encapsulant includes prior to curing, a difunctional acrylate epoxy resin exhibiting pseudoplastic flow and a viscosity of greater than about 0.7x106 centipoise. Accordingly, a method of manufacturing an optical subassembly may eliminate a separate passivation step and instead fill the gap between the die and optical coupler with an optically clear encapsulant.

A flexible heat pipe is disclosed for use with evaporator and condenser elements for removing heat from electronic components. The flexible heat pipe comprises a bellows member fixed at one end to a condenser member and at an opposite end to an evaporator member. A cable artery is disposed within the bellows and is fixed at one end to the evaporator, and slidingly engages the condenser at the opposite end. The bellows acts as a flexible vapor envelope, and the cable artery acts as a flexible wick for directing condensed working fluid from the condenser back to the evaporator. The sliding connection between the cable artery and the condenser allows relative axial movement, and the inherent flexibility of the cable artery allows relative lateral movement. Thus, the condenser and evaporator can move in all directions with respect to each other, which can provide desired vibration isolation of the two components.
