IPC: H01R12/55
Filed: 1990-09-28
Abstract: A method is described for installing contacts (12) with their rear tail ends (54) soldered to holes of a circuit board (56) and their front mating ends (60) in insulative housing layers, which facilitates inspection of the solder connections to the circuit board (56) and defluxing of the assembly after soldering. The front contact portions (60) are partially inserted into holes (14) in an elastomeric housing layer (50) until a first forwardly-facing shoulder (76) on each contact (12) abuts an abutment (92) on the elastomeric layer. The contact rear ends (54) are inserted into corresponding holes in the circuit board (56) until a second rearwardly-facing shoulder (72) on each contact (12) abuts the front face (74) of the board (56), and the contacts (12) are then soldered to the board (56). Finally, the contacts (12) are pushed further into the housing until the rear face (100) of the elastomeric layer lies facewise against the front face (74) of the board (56).

Abstract: A high voltage, high power DC power supply includes a single turn primary winding driven through a resonating capacitor by an AC source having a frequency in excess of about 100kHz. The primary winding includes a pair of concentric cylindrical metal walls having opposite ends electrically connected to each other. A volume between the walls includes plural secondary winding assemblies, having different axial positions along the walls. Each of the assemblies includes an annular magnetic core surrounding the interior wall, a winding on the core and a voltage doubler rectifier. DC voltages developed across each secondary winding assembly by the rectifier are added together to provide the high voltage, high power output. The power supply energizes an X-ray tube having a grounded anode and a cathode at a DC voltage of approximately -150kV, with a power requirement of between 15 and 60kW. The power supply and X-ray tube are mounted on a rotatable gantry including a slip ring assembly for coupling a relatively low voltage excitation source to the power supply.

Abstract: A color cathode ray tube apparatus is provided with an electron gun assembly which emits three electron beams and focuses and converges the electron beam onto a phosphor screen. In the gun assembly, the electron beams generated from cathodes (2) are accelerated and controlled by first and second grids (3, 4) and pass through third, fourth and fifth grids (5, 6, 7). The third and fourth grids (5, 6) have single rectangular apertures (10, 11) common to the three electron beams, respectively, which are faced to each other and have different heights and widths. Each of the fourth and fifth grids (6, 7) have individual apertures which allow the corresponding electron beams to pass therethrough, respectively. The third and fifth grids (5, 7) is maintained at fixed potentials and a potential of the fourth grid (6) is adjusted. Thus, individual focusing and convergence electron lenses (L120) are formed between the fourth and fifth grids (5, 6). A single and common asymmetrical electron lens (L110) is formed between the third and fourth grids (5, 6), when a potential difference between the third and fourth grids (5, 6) is produced. A misconvergence of three electron beams produced due to the adjustment of the individual electron lenses (L120) is corrected by the common asymmetrical electron lens (L110) in such a manner that the side electron beams are deflected in accordance with the potential difference.

Abstract: The invention relates to a thyristor which has, for example between an emitter region (8) and a support emitter region (7), a resistance zone (5) for the purpose of forming a lateral resistance (R), the resistance zone (5) having a well-defined lower dopant concentration than the layer (2) surrounding it. The well-defined lower dopant concentration is produced by recesses (3) in a coating layer and can be adjusted by the width ratio of alternating recesses (3) and ridges (4). The recess (3) and ridges (4) are formed either by diffusion and subsequent etching or by implantation with an implantation mask before the coating layer is driven into the semiconductor body of the thyristor from a surface (O) by heating.

Abstract: An electrophotographic printing machine is provided with a photoreceptor (1) whereon a transparent electrically conductive layer (1 b) and a photoconductive layer (1C) are successively formed. A visible image is formed on the photoconductive layer (1 c) by exposing the photoconductive layer while applying a voltage across toner (T) supplied onto the surface of the photoreceptor (1) and the transparent electrically conductive layer (1c). The exposing energy of the exposure unit is set so as to satisfy an equation:       
where V D1  designates the surface electric potential of the photoreceptor (1) that is exerted when the surface of the photoreceptor (1), originally having a surface electric potential of virtually zero V, passes by the area in contact with the toner; V D  designates the saturation value of the surface electric potential of the photoreceptor (1) that is attained after the surface of the photoreceptor (1) has successively passed by the area in contact with the toner; and V L  designates a lowered surface electric potential of the photoreceptor that is to be reached by an exposure. Therefore, good picture images without being affected by residual images can be obtained.
