A passivated semiconductor structure and associated method are disclosed. The structure includes a silicon carbide substrate or layer; an oxidation layer on the silicon carbide substrate for lowering the interface density between the silicon carbide substrate and the thermal oxidation layer; a first sputtered non-stoichiometric silicon nitride layer on the thermal oxidation layer for reducing parasitic capacitance and minimizing device trapping; a second sputtered non-stoichiometric silicon nitride layer on the first layer for positioning subsequent passivation layers further from the substrate without encapsulating the structure; a sputtered stoichiometric silicon nitride layer on the second sputtered layer for encapsulating the structure and for enhancing the hydrogen barrier properties of the passivation layers; and a chemical vapor deposited environmental barrier layer of stoichiometric silicon nitride for step coverage and crack prevention on the encapsulant layer.

Transistors are fabricated by forming a nitride-based semiconductor barrier layer on a nitride-based semiconductor channel layer and forming a protective layer on a gate region of the nitride-based semiconductor barrier layer. Patterned ohmic contact metal regions are formed on the barrier layer and annealed to provide first and second ohmic contacts. The annealing is carried out with the protective layer on the gate region. A gate contact is also formed on the gate region of the barrier layer. Transistors having protective layer in the gate region are also provided as are transistors having a barrier layer with a sheet resistance substantially the same as an as-grown sheet resistance of the barrier layer.

A speed sensor (B, C) produces a signal that reflects the angular velocity of a shaft (4) which rotates in a case (2) having a mounting surface (10), beyond which the shaft projects to provide a target (6), and threaded holes (12) which open out of the mounting surface. The speed sensor includes a housing (20) and a sensing element (22) which is embedded in the housing. The housing, which is formed from a deformable material, has slots (44, 60) which align with the threaded holes in the case, and receive screws (24, 66) which thread into the holes to secure the speed sensor to the case. The speed sensor is positioned such that the proper air gap exists between its sensing element and the target. The screws, which extend through the slots, produce indentations (56, 74) in the deformable material of the housing, and these indentations receive the screws, so that the position of the sensor is fixed. Thus, the sensor, if removed, may be reinstalled in the same location.

A method for dispensing a liquid includes providing a container having a top, a bottom, a first opening at the top and a second opening proximal the bottom; providing a liquid dispensing bag including a flexible pouch having a top, a bottom, and first and second panels, the first and second panels defining an interior and a first opening to the interior at the bag top, wherein at least one of the first and second panels defines a second opening to the interior near the bag bottom, and wherein the bag further includes liquid dispensing apparatus including a tube connected to the pouch to permit a controlled flow of liquid from the second opening of the pouch, and wherein the first and second panels are connected together at the pouch top to releasably close the first pouch opening. The first pouch opening is opening by separating the first and second panels from each other at the top of the pouch, and the bag is positioned in the container with the tube extending out through the second opening of the container. Liquid is inserted into the bag interior, and liquid dispensing apparatus is actuated to selectively release the liquid out through the tube.

摘要:
The invention provides a process for forming a compound having the formula (I): from chemical entities native [A], native [B] and native [C], where native [A] has a thioester group, native [B] had a 1-amino-2-thiol group with an unoxidised sulfhydryl side chain, and native [C] had a thiol reactive function (TRF) group, wherein chemical entities [A], [B] and [C] are covalently linked by linker group L, comprising the steps of: (i) admixing native [A] and native [B] in a reaction solution; (ii) condensing the unoxidised sulfydryl side chain of native [B] with the thioester group of native [A] for producing a first intermediate compound wherein [A] and [B] are linked with a β-aminothioester bond; (iii) rearranging the β-aminothioester bond for producing a second intermediate compound wherein [A] and [B] are linked with an amide bond having attached thereto a free thiol group; (iv) admixing native [C] with the second intermediate compound in a reaction solution; and (v) reacting the thiol reactive function (TRF) group of native [C] with the free thiol group of the second intermediate compound for producing a compound having the formula (I).
