Abstract: A retractable needle-type syringe having a maximum amount of safety features, including maintaining the needle of the syringe in a retracted and totally shielded position prior to use. After an injection has been given, the plunger rod of the syringe can be operated by one hand of the user in such a manner as to completely and totally disable the syringe and thereby render secondary use of the syringe practically impossible. This feature leaves the other hand of the user out of danger and proximity to the syringe and available to perform other patent-assisting functions. The above multifunctional nature and operation of this invention is accomplished through the use of a minimum number individual components which are uniquely adapted for packaging and cooperative interaction within an elongated cylindrical housing of the syringe.

Abstract: A method and system for continuously correcting for errors in color output of a color copier or printer and caused by events that occur between the input of a color image scanner and the output of a copier or printer driven thereby. This method and system includes, among other things, the continuous comparison of input test pattern data, TP.sub.in, from a small color gamut or "patch" having only a selected few number of color pixels therein with the output test pattern data, TP.sub.out, from a color printer or copier to generate a color correction conversion factor, H. Then, H is used to continuously update an initial full scale look up table which was initially prepared from a full scale color gamut. The initial look up table has a color conversion factor, F.sub.old, and H is used to convert F.sub.old to F.sub.new where F.sub.new =H.multidot.F.sub.old.

Abstract: In a plasma reaction chamber or the like having a supporting electrode for receiving a selected substrate to be etched, a coolant gas is introduced into one region between this substrate and electrode for increasing the heat transfer capacity therebetween. Differential sealing means are provided adjacent to the coolant gas receiving region and define an enclosed space between the substrate and its supporting electrode to which a partial vacuum may be applied. This partial vacuum prevents any cooling gas from by-passing the sealing means and entering the plasma reaction chamber and producing deleterious chemical reaction effects therein.

Abstract: A trash compactor or other materials loading assembly wherein a flexible memory containing ramrod and associated platen may be flexibly driven against a trash load in such a manner as to assume its general contour and provide good trash compacting efficiency. In a preferred embodiment, the ramrod is made of relatively low cost polyvinylchloride (PVC), thereby avoiding the high costs associated with metal components. In addition, the ramrod is flexibly driven by slidable engagement with a PVC piston driver in a seal tight arrangement so as to maintain good liquid tight hydraulic fluid sealing at the side walls of the piston driver. This assembly may be used either in a trash compacting operation or in the high density compacting of new and recyclable materials. The present invention is also directed to a new and improved method of compacting materials in a high density, low cost and efficient mode of operation.

Abstract: A method and system and associated circuitry for controlling and stopping the motion of dangerous moving parts such as power saw blades substantially instantaneously in response to body or human capacitance produced by an operator coming with a predetermined critical distance from the moving part. This method includes, and this system provides for, among other things, connecting an antenna to the moving part and then coupling a tunable circuit to the antenna so that the antenna provides a variable lumped capacitance parameter (dependent upon human body capacitance) within the tunable circuit. This lumped capacitance parameter is variable in response to body or human capacitance produced when an operator comes within a predetermined critical proximity to the moving part.

Abstract: A single series electrical circuit for cooling an electronic device while simultaneously providing series electrical current through the device to provide operational power. In this manner, increases or decreases in operating current through the device causes proportional increases or decreases in Peltier cooling current through one or more Peltier cooling junctions within the circuit to produce a desired increased or decreased cooling of the device with increases and decreases of heat dissipation from the device. The series electrical circuit and method of operation includes the provision of first and second power supply terminals and an electronic device connected to one of the power supply terminals. A Peltier cooling junction is connected to one side of the electronic device where a Peltier heating junction is connected to one side of the Peltier cooling junction.

Abstract: Apparatus for dispensing chlorine pellets and the like into a well or other liquid container. The apparatus comprises a hollow cylindrical body having a grooved passageway therein and further having an end plate with a gate opening therein communicating with the passageway. The gate opening has a cross sectional dimension which is greater than that of the diameter of a single chlorine pellet, but smaller than that of two chlorine pellets, thereby allowing the removal of a single chlorine pellet from the gate opening once during each 360.degree. rotation of the cylindrical body. This motion further causes the next-in-line pellet to drop back into the cylindrical body once each such rotation thereof. A removable cap is mounted at the other end of the cylindrical body and is used for loading pellets into the cylindrical body.

Abstract: An integrated combination of a headlamp section and a sidelamp section for a vehicle, with the sidelamp section being oriented and rotatable at a predetermined wrap-around side facing angle with respect to the forward lighting direction of the headlamp section. This angle may be typically on the order of 90.degree. so that the sidelamp provides good continuous wrap-around side lighting and good night vision for persons riding in the vehicle or exiting therefrom. The sidelamp section may be operated in response to the turning on and off of the dimmer bulb within the headlamp section or it may be operated independently of the operation of the dimmer bulb by the use of an OR gate logic circuit in combination with an electro-mechanical relay and switch. This circuit is operable for energizing and de-energizing the relay and switch in response to power applied to any one of a plurality of parallel connected inputs of the OR gate logic circuit.

Abstract: A process for forming silicon nitride layers on silicon substrates which includes initially heating the silicon substrates in a rapid thermal processor and in a substantially oxygen-free and residual moisture free environment to form a thin Si.sub.3 N.sub.4 layer directly on the silicon surface which is free of any measurable native SiO.sub.2 thereon. Then, the nitridized wafers are transferred into a conventional nitride furnace where the thin Si.sub.3 N.sub.4 layers may be increased in thickness by a desired amount. Typically, the initial or first Si.sub.3 N.sub.4 layer thickness will be about 10-30 angstroms and the second Si.sub.3 N.sub.4 layer will be on the order of 80 angstroms or more to form a composite Si.sub.3 N.sub.4 layer of about 100-150 angstroms in total thickness.

Abstract: A two-terminal, alternating current power control device connected in an electrical path between a load and a remote switch, comprising a current switching device, a controlling device and a direct current power supply device. The current switching device provides a low impedance electrical path in response to the application of triggering signals thereto, and provides a high impedance electrical path in the absence of the triggering signals. A control circuit is provided for applying triggering signals to the current switching device as the proper time in the AC cycle, and is responsive to a momentary interruption in the applied AC voltage so as to effect change in the power intensity or timed duration of power delivered to the load. A remote switch in the electircal path can be the source of a momentary power interruption.

Abstract: A method and apparatus for rapidly determining the print quality of a porous material which includes contacting a porous surface with a source of ink, and then providing a known relative acceleration between the ink source and the porous surface. In this manner, a predetermined volume of ink is transferred from the ink source to a known area of the porous surface. Then, the amount of ink transferred into the porous surface area per unit of time is measured to thereby determine the time between initial ink contact and the initial ink penetration, referred to as the wetting delay, the penetration rate of ink into the porous surface, and the volumetric roughness of the porous material. All of these latter parameters are closely correlated to print quality.

Abstract: A monolithic thermal ink jet printhead is presented. This monolithic structure makes page-width array thermal ink jet printheads possible. The monolithic structure can be manufactured by standard integrated circuit and printed circuit processing techniques. A nickel-plating process constructs a nozzle on top of resistors, thereby eliminating adhesion and alignment problems. A rigid substrate supports a flexible cantilever beam upon which the resistors are constructed. The cantilever beam, together with the ink itself, buffers the impact of cavitation forces during bubble collapsing and results in a better resistor reliablility. The monolithic printhead allows a smoother ink supply since the ink is fed directly from the backside to the resistor through an opening in the rigid substrate. The orifice structure is constructed by a self-aligned, two-step plating process which results in compound bore shape nozzles.

Abstract: A low noise floor phase detector is designed with a transmission line coupler to take advantage of the low noise characteristics of such couplers and their improved operational characteristics relative to a transformer. The preferred detector circuitry also utilizes amplitude detectors that include signal terminating means to operate the diodes at a conduction angle for maximum signal to noise ratio and effective impedance matching between the circuit components.

Abstract: The use of lumped resistive elements (28) in an ink feed channel (10) between an ink-propelling element, such as a resistor, (12) and an ink supply plenum (14) provides a means of achieving resistive decoupling and meniscus resonance control with a minimum of deleterious side effects and design compromises typical of prior art solutions. A secondary constriction (30) in the ink feed channel is defined by a width W.sub.2 sufficient to provide physical support for the resistive elements while avoiding resistance to ink refill. The printhead further comprises lead-in lobes (38) for assisting in purging any bubbles in the ink. The lobes are disposed between the projections and the plenum chamber and separate one pair of projections from a neighboring pair.
