Abstract: A flowable, (e.g., screen printable, stencil printable and/or dispensable) thermally conductive paste is disclosed and provide low temperature curing or firing. The pastes are useful in forming thermally conductive pathways for electronic type applications, such as, providing thermal conduction between a semiconductor chip and its associate semiconductor chip packaging (e.g. power electronic applications), which can be useful in power converters, electrical power steering modules, car head lights (LEDs), solar cells, printed circuit boards (PCBs), plasma display panels (PDPs), and the like. The pastes have a combination of conductive flakes and particles in a minimal amount of carrier fluid and carrier resin to provide advantageous deposition and heat melding properties.

Abstract: A process for the production of a MWT silicon solar cell, wherein a conductive metal paste with no or only poor fire-through capability is applied, dried and fired to form a continuous metallization comprising a top set of conductive metal collector lines and a metallization of the inside of the holes of a p-type MWT silicon solar cell wafer, wherein the top set of conductive metal collector lines superimposes a bottom set of conductive metal collector lines on the front-side of the p-type MWT silicon solar cell wafer, said bottom set of conductive metal collector lines having no contact with the inside of the holes.

Abstract: A process for the production of a MWT silicon solar cell, wherein a conductive metal paste with no or only poor fire-through capability is applied, dried and fired to form a continuous metallization comprising a top set of conductive metal collector lines and a metallization of the inside of the holes of an n-type MWT silicon solar cell wafer, wherein the top set of conductive metal collector lines superimposes a bottom set of conductive metal collector lines on the front-side of the n-type MWT silicon solar cell wafer, said bottom set of conductive metal collector lines having no contact with the inside of the holes.

Abstract: A networking service that receives information about behaviors of the users, such as behaviors in which a user is engaging now or will engage in the future. The networking service compares the behavior information to identify matches between two or more users. When a match is detected, the networking service may form a network (e.g., a social network) between the two or more users by connecting the users in a network. The users may then communicate in the network, and additional users may be added to the network when those users are determined to be engaging in the behavior. When the networking service detects that the users are no longer engaging in the behaviors on which the match was identified, the networking service may disconnect users from one another or the network, and the networking service may eliminate the network.

Abstract: A stud driver has threaded jaws with thread relief provided on a leading edge area of the jaws to reduce thread marking or deformation of the thread on the stud when the stud is driven under high torque conditions. The thread relief in the leading edge area of the jaws creates a shallower angle and increases contact area. If the stud driver is subjected to unusually high torques, the increased contact area prevents shearing of the thread on the stud.

Abstract: There is provided a connector for use between rotatably driven tools, preferably an upper tool which is a torque limiting device, and a lower tool which is a stud driving tool. The connector has a driven head disposed within a socket of an adapter housing, the driven head further being disposed within the body of the lower tool when the combination is assembled. The connector can also allow the body of the lower tool to be freely rotatable with respect to both the adapter housing and the driven head when assembled. Both the torque limiting device and the stud driving tool can be of improved configurations themselves.

Abstract: An automatic stud driving tool is provided having a carriage, and a set of jaws disposed within the carriage. The jaws and carriage are provided with permanent contours that prevent the jaws from being withdrawn from the carriage when the jaws are open, but which do not prevent such withdrawal when the jaws are closed. The carriage and jaws are rotationally interlocked, and the carriage is capable of axial movement within a body element only when the jaws are closed, and axial movement of the carriage within the body results in the engagement and disengagement of a rotational drive from the carriage. Automatic operation of the tool can be enhanced through the use of a depth gauge.

Abstract: A stud driver for the insertion of studs into a workpiece. The stud driver automatically grasps the stud once the stud is inserted into the stud driver. Once the stud is inserted into the workpiece, the stud driver automatically releases the stud. The stud driver employs a set of jaws to grasp the stud. The jaws, which are biased open by a plunger means, are enclosed with a carriage. In the peripheral wall of the carriage, two sets of balls are held. The balls prevent the jaws from sliding out of the carriage and from rotating in the carriage. The carriage is driven by a driven head which is connected to the driving means. The carriage and driven head are held in an uncomplicated hollow cylinder which is the body.

The carriage and driven head are held in an uncomplicated hollow cylinder which is the body. Grooves in the faces of the jaws cooperate with the balls and allow a limited amount of reciprocation of the jaws within the carriage. Movement of the carriage within the body is not essential, so that the body serves to hold the balls in the carriage and to provide structural support.

Abstract: A controlled-torque apparatus having a first cylindrical member and a second cylindrical member held together by means of a ball bearing positioned in a hole in the sidewall of the second cylindrical member cooperating with a bearing race on the interior sidewall of the first cylindrical member, thus longitudinally securing while allowing relative rotation. The torque control is provided by a spring which exerts vertical pressure on ball bearings extending through apertures in the base of the second cylindrical member into part-spherical recesses in the base of the first cylindrical member.
