    Abstract: An electron beam apparatus comprises a TDI sensor 64 and a feed-through device 50. The feed-through device has a socket contact 54 for interconnecting a pin 52 attached to a flanged 51 for separating different environments and the other pin 53 making a pair with the pin 52, in which the pin 52, the other pin 53 and the socket contact 54 together construct a connecting block, and the socket contact 54 has an elastic member 61. Accordingly, even if a large number of connecting blocks are provided, the connecting force may be kept to such a low level as to prevent the breakage in the sensor. The pin 53 is connected with the TDI sensor 64, in which a pixel array has been adaptively configured based on the optical characteristic of an image projecting optical system. That sensor has a number of integration stages that can reduce the field of view of the image projecting optical system to as small as possible so that a maximal acceptable distortion within the field of view may be set larger.

    Abstract: An electrical contact includes a conductor comprising a series of arch-shaped elements that are formed continuous with one another and extend along a centerline. Optionally, the arch-shaped elements are pitched at an acute angle with respect to the centerline and are arranged in separate parallel planes that are also oriented at an acute angle with respect to the centerline. The arch-shaped elements includes a pair of opposed leg portions, having first ends joined to a bridge portion and having second ends spaced apart to form an opening therebetween. The leg portions of adjacent arch-shaped elements are joined to one another at linking portions. The arch-shaped elements and the centerline can be arranged in a circular geometry about a center point.

  • Patent number: 6811453
    Abstract: An apparatus for forming and disconnecting an electrical path includes a split tine socket that is formed of a high yield strength conducting material or metal and which includes a plurality of tines. Each tine functions as a two stage spring to supply a normal force that urges the tine toward the center of the socket. Each tine includes a first stage that has a smaller inside diameter and is therefore thicker than an adjacent second stage. The outside diameter of both stages includes a taper so that the tines are nearly cylindrical when fully mated with a pin. The second stage includes a reverse taper whereby it has a larger inside diameter proximate the first stage than at an opposite end proximate a tip, which ensures that physical, and therefore electrical, contact with the pin will occur at the tip of the tine. The first stage is in electrical contact with a socket contact portion that is typically crimped or soldered onto a wire. A plurality of sockets are typically included in a connector.

  • Patent number: 6752668
    Abstract: An electrical connector employing a radially resistant barrel socket having a bore extending from one end which slidably receives an electrically conductive pin. A spacer member is disposed to space a stop member from the one end of the barrel socket. An inner diameter of a bore in the spacer member is greater than the inner diameter of the adjacent bores in the stop member and the barrel socket to define a recess which receives a projection carried on the pin which the pin is inserted into the barrel socket. An end cap is fixed over the stop member and the spacer member and to the barrel socket to resist axially outward flexure of an inner edge portion of the stop member upon the exertion of pull-out forces on the pin and the barrel socket tending to disengage the pin from the barrel socket.

    Abstract: The present invention relates generally to male to female contact terminals, particularly those in use with associated wire harnesses or cables involved in higher voltage and current carrying vehicle applications. More specifically, the present invention discloses an improved female terminal design for interengaging with a projecting blade of a male terminal and which in particular provides the combined features of improved contact area and controlled blade insertion. Additional features of the present design include the female terminal exhibiting one or more initial (sacrificial) contact points at the blade insertion end and which functions, with or without the application of a magnetic field inducing Lorentz force, to provide a controlled location at which voltage induced arcing will occur along the female terminal and without compromising the electrical interface created between the male terminal blade and the female terminal beams.
