| 61 | Starter relay | US11451863 | 2006-06-13 | US20070001801A1 | 2007-01-04 | Masahide Kobayasi |
| A starter relay comprises a container composed of an electrical insulating hard resin, a resistor having a positive resistance temperature coefficient and housed in the container, and contact springs of feeding devices having conduction and resilience configured to press the resistor to establish connection with the resistor. The contact springs each include a body, two arms extending from the body, and spaced press-fit contacts extending from the arms to press the resistor. The press-fit contacts of one of the contact springs and the press-fit contacts of the other are arranged in crossed directions. Thus, a broken fragment of the resistor is not pinched between the contact springs even when the resistor pinched is broken. | ||||||

| An apparatus (1) that is capable of a first stable configuration and a second stable configuration is disclosed. The bistable mechanism (10) has a leg (30, 32) that is coupled on one end by a base member (22, 24) and on the other end by a shuttle (20). The leg (30, 32) stores potential energy as it is deflected. The potential energy stored in the leg (30, 32) has a maximum potential energy position with a low potential energy position on either side of the maximum. An apparatus and method are also disclosed for a latching mechanism (910) and the associated method. The latching mechanism (910) is comprised of a grasping member (932), a lock slider (928), and a detent slider (916). These three members (916, 928, 932) operate together to induce a locked configuration and an unlocked configuration by actuating the lock slider (928) in a single direction. | ||||||

| A microelectromechanical (MEMS) device is provided that includes a microelectronic substrate, a microactuator disposed on the substrate and formed of a single crystalline material, and at least one metallic structure disposed on the substrate adjacent the microactuator such that the metallic structure is on substantially the same plane as the microactuator and is actuated thereby. For example, the MEMS device may be a microrelay. As such, the microrelay may include a pair of metallic structures that are controllably brought into contact by selective actuation of the microactuator. While the MEMS device can include various microactuators, one embodiment of the microactuator is a thermally actuated microactuator which advantageously includes a pair of spaced apart supports disposed on the substrate and at least one arched beam extending therebetween. By heating the at least one arched beam of the microactuator, the arched beams will further arch. In an alternate embodiment, the microactuator is an electrostatic microactuator which includes a stationary stator and a movable shuttle. Imposing an electrical bias between the stator and the shuttle causes the shuttle to move with respect to the stator. Thus, on actuation, the microactuator moves between a first position in which the microactuator is spaced apart from the at least one metallic structure to a second position in which the microactuator operably engages the at least one metallic structure. Several advantageous methods for fabricating a MEMS device having both single crystal components and metallic components are also provided. | ||||||

| 72 | Micromachined bi-material signal switch | US271811 | 1994-07-07 | US5467068A | 1995-11-14 | Leslie A. Field; Richard C. Ruby |
| A micromachined signal switch for vertical displacement includes a fixed substrate having at least one signal line and includes an actuator substrate that is thermally actuated to selectively connect a second signal line to the first signal line. The actuator substrate includes a plurality of legs constructed of materials having sufficiently different coefficients of thermal expansion to create stresses that arc the legs when the legs are subjected to elevated temperatures. In the preferred embodiment, a first material for forming the legs is silicon and a second material is a metal, such as electroplated nickel. A displaceable contact region may be formed integrally with the actuator substrate, but the contact region is preferably a region of an interposer substrate between the fixed substrate and the actuator substrate. The displaceable contact region has a raised position in which the signal line on the fixed substrate is "off" and has a lowered position in which a conductive member on the contact region is positioned to provide electrical communication to the signal line. | ||||||
| 73 | Thermally actuated micromachined microwave switch | US212544 | 1994-03-14 | US5467067A | 1995-11-14 | Leslie A. Field; Richard C. Ruby |
| An integration of a micromachined actuator and a signal transmission structure includes a thermal actuator on a side of a displaceable signal line opposite to a fixed signal line. The actuator includes first and second legs. The first leg has a cross-sectional area greater than the second leg, providing a differential in electrical resistance. As current is channeled through the legs, the second leg will elongate more and will deflect both of the legs. The deflection is in a direction to press the displaceable signal line into signal communication with the fixed signal line. Optionally, a thermally operated reset actuator can be positioned to provide a mechanical return of the displaceable signal line. In a preferred embodiment, a microwave transmission environment is provided. | ||||||
| 74 | Liquid contact relay incorporating gas-containing finely reticular solid motor element for moving conductive liquid | US69249 | 1979-08-23 | US4419650A | 1983-12-06 | Frank T. John |
| It has been discovered that electrically conducting, vitreous pyrolytic carbon in broken-bubble, foam-type, reticulated structures can be used as an extremely fast and efficient electrically operated motor to actuate mechanical devices, such as mercury liquid contact relays, by electrothermally-produced gas expansion. The gas pressure change is produced evenly and almost instantaneously throughout the volume of the reticular motor to move mercury contacts, to open or close a liquid contact relay, thus avoiding the expensive electromagnetic coils now used as relay motors.By passing an electrical current through conducting reticulated material formed from pyrolytic carbon, metals, conductive ceramics or plastics, the microscopic network of interconnecting filaments is heated, thus heating and expanding the fluid (air, hydrogen, helium, argon, etc.) contained in the reticular motor.The time required to operate the device depends on the thermal gradient and the square of the average thermal diffusion distance between the gas and the nearest heating filament. Since the diffusion distance is very small, the device is very fast and efficient. For fast repetative motor operation, a reticulated material of high thermal conductivity such as silver, silicon nitride, or boron nitride, is sealed to the inside walls of the motor.The reticular electrothermal motor is useful for operating mechanical devices including both miniature logic relays and large industrial relays. The high power requirement of the latter may be supplied by using change of state expansion of volatilizable liquids such as are used as refrigerants or as propellants in aerosol spray containers. | ||||||
