Abstract: An anti-decoupling mechanism for preventing unwanted decoupling of an electrical connector as a result of vibration. The decoupling mechanism includes a one-piece gull-shaped spring (400) mounted to a connector coupling ring (300). The spring (400) includes a central portion (410) having an arcuate groove (411) formed thereon and a pair of wing members (420, 430) extending outwardly therefrom, the arcuate portion being secured in place by a pin (600) interference fit through a hole (331) disposed in the coupling ring. Each wing member includes first and second strips in superposed relation and a medial enlargement or tooth member (440) projecting radially inward from a forward surface of one of the strips and adapted to engage ratchet teeth (141) disposed on one of the connectors, the wings biasing the tooth against the ratchet teeth to increase anti-decoupling torque.

Abstract: A high-electron mobility transistor (HEMT) has an undoped GaAs layer (2); and an N-doped AlGaAs layer (3); a heterojunction (12) formed between the undoped GaAs layer and N-doped AlGaAs layer (2) and (3), respectively; a gate electrode (10) on the N-doped AlGaAs layer (3); and an electron-storing layer formed in proximity to the heterojunction (12) due to the difference in electron affinity between the undoped GaAs layer (2) and the N-doped AlGaAs layer (3). The known HEMT has a disadvantage in that during the formation of the source and drain regions by means of, for example thermal diffusion, the impurities of the N-doped AlGaAs layer (3) may diffuse into the undoped GaAs layer (2) through the heterojunction (12) so that the mobility of the electrons in the electron-storing layer (17) is lessened. This disadvantage is removed in the present invention by the provision of a conduction layer (7) formed by the epitaxial growth of highly-doped GaAs. The known HEMT also has a disadvantage in that the source electrode (9A) or the drain electrode (9B) is electrically connected to the N-doped AlGaAs layer (3) so that the electrons in this layer (3) may lessen said mobility. This disadvantage is also eliminated in the present invention by the provision of an insulating layer (6).

The sidewall edge margin defining the cap open end has a continuous radially inwardly directed flange (22) which forms an opening which is less than the cross-section of the hub (10) taken through the keying member (12). The cap also has a depression (23) in the inner surface of its cylindrical sidewall (21) so that the inner diameter of the cap at that portion is greater than the hub cross-sectional diameter taken through the keying member (12). 
     Metal lining means (24) are affixed tothe inner surface of the cap end wall (20) so that a portion (26) of the lining means extends partway along the cap sidewall (21). The dimension of the lining means are such that the lining means make adequate contact with the end portion (17) of the connector part when the cover (19) is in place.

Abstract: A digital induction resistivity logging tool is disclosed for digitally measuring both the in-phase (R) and quadrature (X) phase components in a receiver signal generated in response to transmitter induced currents flowing in the earth's subsurface formations. The digital induction tool includes a digital sinewave generator for generating a highly phase stable, low distortion transmitter signal, the frequency of which is selectable from among a plurality of transmitter frequencies. One phase sensitive detector is used alternately to detect both the R and the X phase component signals. Automatic phase compensation is included to periodically compensate for both static and dynamic temperature dependent phase shift errors due to circuits of the tool involved in the component measurements. A floating point analog-to-digital converter capable of handling the wide dynamic range in the detected phase component signals is provided to convert the phase detector output into digital signals. Selection of the transmitter frequency may be based on optimizing the measurement of the characteristic of the formations being encountered by the tool. A linearization correction function is obtained periodically for the tool transfer function as the tool is being used in normal logging operations. The function is then applied to measurements taken subsequently.

Abstract: A pressure servomotor has a driving diaphragm for driving an operation shaft connected to a load. The position of the driving diaphragm is determined by a control position determining means which in turn operates a response to a control signal. When the driving diaphragm has been deflected to the control position determined by the control position determining means, the driving pressure applied to the driving diaphragm is weakened and, when the driving diaphragm is moved apart from the control position, the driving pressure applied to the driving diaphragm is in-creased. In consequence, the driving diaphragm is set at the control position determined by said control position determining means.

(3) employing said alkali metal hydroxide as an aqueous solution and adding said aqueous alkali metal hydroxide in a continuous manner over a period of from 0.5 to 10 hours. (4) continuously removing water by means of codistillation at a rate such that the water content of the reaction mixture is less than 6 percent by weight: and (5) separating the water from the condistulate and returning the solvent and epihalohydrin to the reaction mixture. The process of this invention maximizes the epthalo- hydrin yields and produces epoxy resins low in hydrolyzable halide.

Abstract: An air atomising nozzle assembly for electrostatic spray guns is disclosed. The nozzle assembly is made of plastic parts and includes an air cap having a central bore which surrounds a fluid nozzle tip. The nozzle has a nut formed on its forward end to facilitate threading of the rearward end of the nozzle tip into a threaded bore of the gun body. Formed on the front part of the nozzle, either as a part of the nut or a cylindrical surface adjacent the nut, is an accurately machined surface engageable in press fit relationship with a mating accurately machined bore of the air cap. These mating press fit surfaces centre the bore of the air cap relative to the nozzle tip so as to leave an annular, evenly dimensioned air flow passage surrounding the nozzle tip and defined between the nozzle tip and the bore of the air cap. The air cap is retained in a one-piece resilient retaining ring by snapping the air cap into an annular lip of the retaining ring. The retaining ring is then threaded onto the gun body to secure the nozzle assembly onto the gun body.

Abstract: A porous gas fed electrode (14) adapted to operate in a large capacity cell (10) with a stable three phase interface in the electrode thereby avoiding the problems of gas percolation can be readily achieved in a simple and inexpensive manner by the provision of a porous hydrophilic layer (21) on the surface of the electrode which is in contact with the aqueous electrolyte (17). Due to the high capillary pressure exhibited by liquids in hydrophilic pores, very high gas pressures are required to force the gas through the structure and the loss of gas into the electrolyte is thereby eliminated. In addition, a gas pressure in the gas compartment (23) of the electrochemical cell employing such an electrode can be raised to balance the electrolyte pressure at the bottom of the electrode thereby effectively preventing electrolyte seepage into the gas compartment.

Abstract: A monolithic orifice plate/resistor combination (11) is provided for which the active elements can be easily aligned using standard mask aligning equipment. First an orifice plate (27) is formed, typically a flat sheet with orifices (23, 25) therein. A passivating layer (29) is then grown on the sheet, and the resistors (13, 15) and conductors (17, 19, 21) to supply them are deposited onto the passivation layer using standard deposition techniques. A spacer (31) is then attached to the passivation layer to define capillary channels for ink flow and to provide increased hydraulic impedance between resistors, thus, completing the structure for the monolithic orifice plate/resistor combination. A completed print head is then made by attaching a sheet of material to the spacer to supply a back to the device and to form the closure for the capillary channels defined by the spacers.
