摘要： A low loss diode ORing circuit has a feed input connected in series with a diode/transistor parallel network and the ouput. Heat is generated by the transistor when the transistor is turned on. A thermally conductive material (such as a heatsink) can dissipate heat and transfer heat from the transistor to the diode. The generated heat is transferred to the diode via the heatsink. As a result of the increased temperature of the diode and the diode's own negative temperature coefficient on conduction voltage, the diode's characteristic conduction threshold is reduced and the diode begins to conduct and share the current load as the current increases, thus providing minimal power dissipation as the current is routed to an output. A comparator may be used to monitor a voltage difference between the voltage level on the feed input and a voltage level on the output. If the difference between the voltage level on the feed input and a voltage level on the output is greater than a predetermined threshold, a problem condition is indicated and the comparator turns off the transistor via a shutdown signal to effectively isolate the feed input.

摘要翻译： 低损耗二极管ORing电路具有与二极管/晶体管并联网络和输出串联的馈电输入。 当晶体管导通时，晶体管产生热量。 导热材料（例如散热片）可以散热并将热量从晶体管传递到二极管。 所产生的热量通过散热片传送到二极管。 由于二极管的温度升高和二极管本身的导通电压负温度系数的增加，二极管的特性导通阈值降低，二极管开始导通，并随着电流的增加共享电流负载，从而提供最小的功耗 电流被路由到输出。 比较器可用于监测馈电输入端的电压电平与输出端的电压电平之间的电压差。 如果馈电输入端的电压电平与输出端的电压电平之间的差值大于预定阈值，则会显示问题状态，比较器通过关断信号关断晶体管，以有效隔离馈电输入。

摘要： The present invention provides a current limiting circuit breaker having a plurality of current responsive devices for opening a pair of contacts upon short circuit conditions. One such device is a conventional magnetic tripping mechanism. The other device utilizes an insulating object driven by a magnetic force caused by the short circuit current. Upon opening of the contacts with the use of the insulating object, let-through current flows through a secondary contact, positioned on the insulating object, to a positive temperature coefficient resistivity element which limits the current and arcing in the contacts. In an alternative embodiment, at least one steel component is added to increase the magnetic force, thereby providing a greater force on the insulating object. An insulation component is also added to further suppress any arc generated between the contacts when going from a closed state to an open state. In another alternative embodiment, the magnetic tripping mechanism is actuated by the device utilizing the insulating object driven by the magnetic force.

摘要： A fuse comprising a tubular fuse casing and first and second conductive ferrules located on the exterior of the casing at opposite ends thereof. The second ferrule has an opening therethrough. A first short circuit fusible element is attached to the first ferrule, and a heater is attached to the second ferrule. A time delay over-current trigger mechanism electrically connects the first fusible element and the heater to each other in series in an electrical path between the conductive ferrules. The mechanism is connected to receive heat from the heater and to mechanically interrupt the electrical path when the heater heats up under low over-current conditions. An indicator mechanism is provided for indicating when the electrical path between the conductive ferrules is interrupted. The indicator mechanism is comprised of an indicator movable from a first position wherein the indicator is substantially within the casing to a second position wherein a substantial portion of the indicator is outside the casing. An indicator-biasing element biases the indicator toward the second position. A second short circuit fusible element maintains the indicator in the first position. The second fusible element is electrically connected between the first and second ferrules in parallel within the first fusible element. The second fusible element has a current carrying capacity below said low over-current conditions.

摘要： In a microcomputer equipped with a built-in temperature sensor, diodes as a temperature sensor are incorporated in a pair of circuit blocks, respectively, and placed in opposite polarity connection to each other. When detecting a temperature of the microcomputer, a constant current If is supplied to the diodes through terminals commonly connected to both the diodes. A voltage Vf generated at each diode is read through terminals located at more adjacent nodes to the diode when compared in position with the terminals.

摘要： A motor-driven curtain assembly includes a drive shaft mounted rotatably in a top rail, a motor for driving rotatably the drive shaft, and a curtain unit coupled to the drive shaft for movement between closed and open positions. A motor-control device includes a driving circuit for enabling rotation of the motor in one of positive and negative directions under the control of a control unit, a current limiting circuit for limiting current flow from an external power source to the driving circuit when the motor is subjected to an increase in load resistance, and an over load detector for generating a control signal that is indicative of the amount of current flowing from the current limiting circuit to the driving circuit and that is provided to the control unit, thereby enabling the control unit to deactivate the driving circuit for stopping operation of the motor when overloading of the motor occurs.

摘要： A chip burn-in system maintains the temperature of IC-chips near a set point, while the IC-chips undergo large step increases and large step decreases in power dissipation as they are tested. The system includes a hot fluid circuit in which a hot fluid circulates from a reservoir through heat exchangers and back to the reservoir, and in which the heat exchangers exchange heat by conduction between the hot fluid and the IC-chips. To keep the temperature of the fluid in the reservoir nearly constant, the system includes an electric heater which operates with a fast response to add heat to the fluid returning to the reservoir as a function of one control signal; and an analog valve which operates with a slow response to add a cold fluid to the reservoir as a function of another control signal. These control signals cause an operating mode where heat is added by the heater, and simultaneously, cold fluid is added through the analog valve; and as a result the net temperature of all of the fluid which is entering the reservoir can be rapidly reduced. This rapid cooling cannot be obtained by the analog valve alone because the valve is a mechanical component whose speed of operation is inherently limited by mechanical inertia.
