5results about How to "Minimize changes" patented technology

A flux and a solder paste capable of minimizing the time-dependent changes in viscosity when stored at 30°C and minimizing the coloration of flux residues while having favorable reflow properties and favorable cleanability of flux residues are provided. As such a flux, a flux containing a rosin, a thixotropic agent, an activator, and a solvent is adopted. The rosin includes one or more selected from the group consisting of an acid-modified rosin, a hydrogenated rosin, and an acid-modified hydrogenated rosin, and the thixotropic agent includes a compound represented by General Formula (1). In General Formula (1), R11 and R12 each independently represent a hydrocarbon group which has 1 to 3 carbon atoms and may have a substituent, or a single bond. R21 and R22 each independently represent a hydrocarbon group which has 7 to 29 carbon atoms and may have a substituent. R13 represents a substituent, n represents an integer of 0 to 4.

A driveline and constant velocity joint for a recreational vehicle are disclosed. The universal joint includes a housing, a bore connected with the axle, and an inner member rotatably connecting the axle to the housing. The retention mechanism improves retention of the constant velocity joint, including hydraulic-based, disc-based, pin-based, spline-based, and spring ring-based mechanisms. The hydraulic-based system maintains engagement with an adjustable hydraulic pressure. The disc-based mechanism employs a conical disc that provides additional friction to resist the pull-out force. The pin-based retention involves corresponding tracks or grooves in the drive pad or pin and in the shaft interface gear. The spline-based mechanism includes a tool-free locking axle shaft retention system having a rotationally interrupted spline. The spring ring-based retention is a plurality of flexible retention rings placed axially along the spline, providing improved shaft retention. The retention mechanism enhances the performance and reliability of the driveline by securing the connections of the constant velocity joints.

An in-line manufacturing apparatus for a lithium metal battery comprises: a lithium foil tape unwinder peeling a release film on the lithium foil tape and transferring the lithium foil tape peeled off the release film to a notching part; the notching part forming an anode plate having an electrode tab by processing the lithium foil tape; and a stacking part inserting a separator film between the anode plate and a cathode plate directly transferred from the notching part in a zigzag manner to alternately stack the separator film.

Disclosed are a method for making a planting surgery plan and an apparatus thereof. In the present invention, when making a planting surgery plan, individual teeth are grouped, and crown arrangement information of a target tooth is determined using tooth axis information of teeth belonging to the same tooth group as the target tooth. Accordingly, the accuracy of crown arrangement is improved, and user modification can be minimized.

Disclosed is to a negative electrode composition, a negative electrode for a lithium secondary battery including the same, and a lithium secondary battery including a negative electrode.
