    Abstract: A flexible and efficient bulk micromachining method for fabricating a novel microstructure that is bounded by substantially planar surfaces meeting only at substantially right angle corner features. The novel microstructure of the present invention is useful as a spacer in assembly processes where high accuracy is required, such as precise positioning of optical fibers or conductors. In the preferred embodiment, the microstructure of the present invention includes a shelf feature disposed along a height dimension of the microstructure, which is required for some applications. The bulk micromachining method of the present invention includes providing a first substrate having a top planar surface and an opposing planar surface. The opposing surface of the substrate is anisotropically etched to provide a first thinned region. The top surface of the first substrate is anisotropically etched so that a first recessed feature having a vertical side is made integral with the first thinned region. Similarly, a second substrate having a top planar surface and an opposing planar surface is provided. The opposing surface of the second substrate is anisotropically etched to provide a second thinned region. The top surface of the second substrate is anisotropically etched so that a second recessed feature having a vertical side wall is made integral with the second thinned region. The top surface of the first substrate is aligned and coupled with the top surface of the second substrate to produce the desired microstructure. The substrates are cut or sawn to free the microstructure.

    Abstract: A method of forming a sulfur-resistant catalyst is disclosed wherein a zeolite is bound with an alumina containing either an alkali or alkaline earth component. In one embodiment of this method, a solution of an alkali metal aluminate or alkaline earth metal aluminate is formed, the pH of the alkali metal aluminate solution is adjusted to a pH of from 6 to 8, and the solution is aged and mulled with a large-pore zeolite to form a mixture. This mixture is extruded to form an extrudate, which is dried, calcined, and impregnated with a Group VIII metal to form a catalyst. Finally, the catalyst is dried and calcined.

    Abstract: A system for maintaining and/or cooling the temperature of a body of water exposed to sunlight comprises hydrophilic balls distributed on the surface of the water. The balls have diameters within a range of about 0.015-3.0 mm, and albedos within a range of about 0.15-1.0. The surfaces of the balls provide a total wetted surface area greater than the pre-distribution surface area of the water. In one embodiment, the body of water may be a natural or unnatural lake or bay.

    Abstract: A method of manufacturing a valve for a fluid system is described herein. The method comprises determining a target cracking pressure for the valve of the fluid system, providing an inner wall having a first height and an outer wall having a second height, the first height varying from the second height by a height differential, and attaching a flexible membrane to the outer wall at the second height, wherein a central zone of the flexible membrane is in contact with the inner wall at the first height and the inner wall biases the flexible membrane from a neutral condition. The height differential is selected to provide resistance to displacement from the inner wall until pressure acting on the membrane exceeds the target cracking pressure.

    Abstract: A method of manufacturing an ink jet print head with a substrate defining an ink aperture. A number of ink energizing elements are located on the major surface of the substrate. A barrier layer is connected to the upper surface, and peripherally encloses an ink manifold. The barrier encompasses the ink aperture. An orifice plate is connected to the barrier layer, spaced apart from the substrate's major surface, enclosing the ink manifold. The plate defines a number of orifices, each associated with a respective ink energizing element. The ink manifold is an elongated chamber having opposed ends defined by end wall portions of the barrier layer. The barrier end wall portions each have an intermediate end wall portion protruding into the manifold.

    Abstract: A bubble valve that comprises a liquid delivery channel and a localized heating arrangement. The liquid delivery channel includes an upstream portion and a constriction downstream of the upstream portion. The constriction has a smaller cross-sectional area than the upstream portion. The localized heating arrangement is located in the liquid delivery channel and generates heat to nucleate and enlarge a bubble in the liquid. The constriction is shaped to form a seal with the bubble. The localized heating arrangement additionally generates heat to move the bubble relative to the constriction to control the flow of the liquid. A pressure regulator that comprises a liquid delivery channel connected to a liquid outlet, a sensor located adjacent the liquid outlet, a controller that operates in response to the sensor and a localized heating arrangement. The liquid delivery channel includes an upstream portion, and a constriction located between the upstream portion and the liquid outlet. The constriction has a smaller cross-sectional area than the upstream portion. The localized heating arrangement is located in the liquid delivery channel and generates heat in response to the controller to nucleate and enlarge a bubble in the liquid. The constriction is shaped to form a seal with the bubble. The localized heating arrangement additionally generates heat to move the bubble relative to the constriction to control the flow of the liquid to the liquid outlet.

    Abstract: A pressure regulator that sets the pressure of a liquid to a predetermined pressure differential below a reference pressure, such as atmospheric pressure. The pressure regulator comprises a liquid delivery channel and a capillary array. The liquid delivery channel includes a liquid input and a liquid output. The liquid flows through the liquid delivery channel from the liquid input to the liquid output. The capillary array is composed of ones of an elongate capillary. The capillary includes a first end in fluid communication with the liquid delivery channel and a second end in pressure communication with a source of the reference pressure. The liquid flows through the first end into the capillary to form a liquid surface in the capillary. The second end is remote from the first end. The capillary has cross-sectional dimensions in relation to the surface tension of the liquid and the angle of contact between the liquid and the capillary such that the pressure drop across the liquid surface in the capillary is equal to the predetermined pressure differential.
