Abstract: An electrical connector assembly (20) includes a two piece die-cast conductive shell (30) that is adapted to be clamped onto a shielded electrical connector (22). The electrical connector may be formed of a dielectric housing (24) with four sidewalls extending between a mating end (44) and a wire receiving end (46). A plurality of contacts (26) disposed in the housing are adapted to be connected to conductors (50) extending into the wire receiving end of the electrical connector. A stamped and formed conductive shield (28) surrounds at least a portion of the housing sidewalls. The two piece die-cast or molded plastic shell is formed by the mating of two shell portions (80,90) with a set of screws projecting through one of the shell portions into the other of the shell portions. When so mated, the shell engages the connector shield (28) to thereby couple the shell (30) to the connector shield and a pocket (164) is formed adjacent the wire receiving end of the electrical connector for enclosing splices between the shielded conductors (32) in a cable and the conductors (50) extending out from the wire receiving end of the electrical connector (22). In addition, the rear end of the mated shell portions form a wire clamping section (102,134) for coupling the shell (30) to a braided shield (84) of the cable and for providing a strain relief for the cable. The wire clamping section may be disposed so that the cable is held at a desired angle with respect to the electrical connector housing.

Abstract: Representative pixel data is extracted for each predetermined region in an original image according to priority of color codes representing colors. The representative pixel data constitute a reduced image. The reduced image is a clear and complete reproduction of the original image without line missings and distortion of a desired linework. M pieces of pixel data on each scanning line are successively read until the pixel data reaches a maximum value Xmax in a main scanning direction. One pixel data having a color code with the highest priority is selected from the read pixel data according to a priority code table TBL. The results of selection for two adjacent scanning lines are compared based on the priority code table TBL, and final representative pixel data is selected.

Abstract: A programmable processing device has a built-in a program memory (14) for storage of data including program instructions for controlling a functional unit (20) of the device. The device also includes signature generating means (18) for combining data read from all locations of the memory (14) during a memory test sequence, to generate a signature word which can be used to verify correct programming and operation of the memory. The device includes means for supplying the generated signature word to an instruction decoding means (20) at the end of the memory test sequence for execution as a normal program instruction. The signature word thus directly determines subsequent operation of the device, enabling the verification result to be communicated externally without the need for a dedicated data path for communicating the signature value itself outside the device. Any desired signature word/instruction can be achieved by including a seed word in the stored data.

Abstract: Difunctional halo silicon amide compounds are prepared by cleaving the nitrogen-silicon bond in a nitrogen-silicon heterocycle with a reactive halide. The reaction is straight forward with no intermediates or byproducts. The halo functionality is capable of capping any SiOH group. When the other functionality is an acrylamide, the capped entity may be polymerized or crosslinked by free radical initiators of the acrylamide functionality thereby producing useful products such as paper release coatings and photoresists.

Abstract: A thermal technique for reducing print density shifts due to print wait time in thermal ink jet printers. The ink jet firing resistors of the printhead are driven with warming pulses having a pulse width insufficient to cause ink drop firing at the warming pulse frequency. They are driven for an interval that depends on the amount of time that has elapsed since printing by the printhead last occurred, or an interval that depends on the amount of decrease in the printhead temperature since printing stopped. In a particular embodiment of the printhead warming technique, the warming pulses have the same amplitude as the ink drop firing pulses, and a higher frequency.

Abstract: Non-linear effects in an optical fiber used for communicating AM signals at high power levels are reduced by increasing the linewidth of the pump laser output signal. The linewidth can be increased by optically broadening the laser output signal by driving an optical angle modulator with broadband electrical noise. The optical signal is then externally modulated with an AM information signal for transmission over an optical link fiber. The optical modulation can be provided using either an FM or PM optical modulator. A desired linewidth can be provided by controlling the optical modulation index during the optical modulation step and/or by controlling the bandwidth of the noise source. Other techniques for broadening a laser output signal, including modulating the signal by a periodic function such as a sine wave, or injecting spontaneous emissions into the laser cavity, are also disclosed.

Abstract: The specification describes and claims a method of making silicone foam compositions comprising the steps of introducing into a moulding cavity a quantity of foamable silicone compositions which is curable at room, or slightly elevated, temperature and bring about curing in the cavity to produce a cured silicone foam. The moulding cavity is closed prior to foaming thereby restricting expansion of the foam. The volume of the closed moulding cavity is a minimum 10% less than that which would be occupied by the composition if it foamed and cured at room temperature without restriction. Lower density foams formed by the above procedure may be converted into rigid elastomeric low density materials by a heat or microwave post cure. For a given composition and foam density the fire resistance of a foam produced by a method according to the invention is greater than a foam which is allowed to foam freely.

Liquid is dispensed through an orifice (69) via a dispensing channel (67) which in one embodiment is purged during a terminal part of the actuating stroke by the release of air through the dispensing channel. In a second embodiment air and liquid are mixed during the actuating stroke so as to be dispensed together and during a return stroke air is sucked through the dispensing channel to remove residual liquid. The air purging action prevents the build-up of deposits in the dispensing channel and orifice.

Abstract: In a wafer fabrication process in which a photoresist stripper must be removed from the surface of a semiconductor wafer, the photoresist stripper is rinsed by inserting the wafer in a vessel (23, FIG. 3) filled with water and simultaneously pumping carbon dioxide and water into the vessel to cause the water to overflow the vessel. Preferably, the wafer is contained within the vessel for at least five minutes, and, during the rinsing step, the water completely fills the vessel and overflows at a rate of at least fifty percent of the volume of the vessel each minute. We have found that this method of rinsing photoresist stripper from semiconductor wafers significantly reduces or eliminates the incidence of corrosion pitting on aluminum conductors (12, FIG. 1) of the wafer (11).
