摘要： A relay device using a conductive fluid and having excellent switching response is provided. This relay device mainly comprises a laminate having an interior space, and formed by bonding a semiconductor substrate to an insulating substrate, at least two contacts exposed to the interior space, a diaphragm portion facing the interior space, a conductive fluid sealed in the interior space, and an actuator for elastically deforming the diaphragm portion. By forming the diaphragm portion on the semiconductor substrate, it is possible to reduce a driving force of the actuator needed to elastically deform the diaphragm portion, and obtain a volume change of the interior space with good response. This volume change causes a positional displacement of the conductive fluid in the interior space, thereby forming a conductive state or a non-conductive sate between the contacts.

摘要： Microdevices based on surface tension and wettability are useful as sensors, detectors, actuators, pumps, among other applications. As sensors and detectors they can respond to numerous stimuli such as pressure, temperature, gravity, rotation, acceleration, oscillation, chemical environments, magnetic fields, electric fields, radiation, and particle beams with a great choice of output options. Because of their design, they can be used in a broad range of temperatures and environments. Additionally, unlike other microsensors and detectors, these devices can be exposed to forces and pressures orders of magnitudes greater than their design limit and still return to their original accuracy and precision. These microdevices are also useful as actuators, pumps, valves and shutters. It is possible by joining these devices together to form complex devices that are able to control macroscopic flows for example. They are also able to perform complex electrical switching operations.

摘要： A switch for use in an inductive energy store transfer circuit utilizes a quantity of electrically conductive liquid bidirectionally flowable between a position that establishes electrical connection between electrodes and a position that opens electrical connection between the electrodes. High pressure gas biases the liquid to a position that establishes electrical connection between the electrodes, and yieldably resists movement of the liquid toward the position that opens electrical connection between the electrodes. Current through the switch electrodes produces a magnetic force that acts on the liquid and urges it toward the position that opens electrical connection between the electrodes. Switching action occurs upon a predetermined magnitude of current being attained.

摘要： A pressure switch has a support structure on which a flexible diaphram is mounted in communication with a source of variable pressure such as a fluid conduit. A first linkage has one end operatively connected to the diaphram and the other end pivotally connected to a cradle having a mercury switch mounted therein. A second linkage is pivotally connected at one end to the support structure and pivotally connected at the other end to the cradle so that the cradle is freely pivotable in response to movements of the first linkage. A quantity of liquid mercury in the mercury switch moves into and out of contact with the mercury switch electrodes in response to pivotal movement of the cradle by the first linkage when the diaphram is moved between first and second positions corresponding to low and high pressure conditions respectively.

摘要： A mercury switch has two spaced apart electrical contacts mechanically supported by its glass envelope and electrically connected to external terminals. A third conductor passes through the glass envelope at the opposite end. A housing for mercury is formed by divergent plates supported on the third conductor, which housing extends into the mercury reservoir near its support so as to draw mercury into the space between the divergent plates. A magnetic partition is supported from the third conductor by a flexible hinge which allows the partition to move back and forth between the divergent plates of the housing alternately into each of a pair of stops between said two spaced apart electrical contacts. Whichever wall of the housing the partition is closest to, the space is narrowed so that the mercury rises under capillary attraction and contacts the electrical contact between the wall and the partition. As the mercury rises in this narrow area, it lowers in the space between the partition and the other wall as it widens causing contact to be broken between the mercury and the other one of the pair of electrical contacts. The situation is reversed as the partition moves to the other position. One position is preferably the stable or normal condition of the switch. The other position is the energized position in which magnetic field is applied to move the armature on the position and change switch condition.

摘要翻译： 水银开关具有两个间隔开的电触头，由其玻璃外壳机械支撑并电连接到外部端子。 第三根导体在另一端穿过玻璃封套。 用于汞的壳体由支撑在第三导体上的发散板形成，该壳体在其支撑件附近延伸到汞储存器中，以将汞吸收到发散板之间的空间中。 磁性隔板由第三导体通过柔性铰链支撑，该铰链允许隔板在壳体的发散板之间来回交替地移动到所述两个间隔开的电触点之间的一对挡块中的每一个中。 无论分隔件最靠近的外壳的哪个壁，空间变窄，使得汞在毛细吸引下升高，并与壁与隔板之间的电接触接触。 当汞在这个狭窄的区域上升时，它在隔板和另一个壁之间的空间中降低，因为它变宽，导致汞与另一个电触点之间的接触被破坏。 当分区移动到另一个位置时，情况相反。 一个位置优选地是开关的稳定或正常状态。 另一位置是施加磁场的通电位置，以使电枢在位置上移动并改变开关状态。

摘要： An electric current control unit to be placed electrically between a current source and an electrically driven member to regulate energy flow from the source. The unit includes a piston head and cylinder of non-conductive material and, in the piston head, an annular ring of an electrically conductive material is carried. A plurality of axially spaced discrete electrically conductive segments are arranged in the cylinder wall. Circuit means connect the source and each of the segments through an impedance element which offers a different resistance to the current flow from the source to each segment. A conductor means connects the piston head ring, which is preferably mercury, with the electrical unit or member to be driven. When the piston is moved through the cylinder, it successively makes contact with the segments to permit current to flow from the source. Preferably a balance circuit is provided which electrically connects the mercury ring and one of electrical segment, the one which is axially adjacent to the top normal position of the piston. The balance circuit includes a switch that is normally open but, on initiation of movement of the piston, is closed by mechanical means, so that as the ring in the piston head makes initial contact with the first segment, a component of current flow takes place from the top segment to the piston head ring which overcomes arcing problems.
