摘要： A positive thermistor device used in a motor activating circuit device of a refrigerator for example includes a positive thermistor element having a pair of opposed electrodes, each of which receives compressive force elastically applied from a corresponding one of spring contact members to hold the thermistor element at a predefined position in the device. When the thermistor device is destroyed, the element breaks into fragments, some of which remain in contact with the spring contact members. The remaining fragments deviate in position to ensure that they do not conduct electricity, resulting in an open state, wherein any current flow is inhibited through such fragments. More specifically, a positive thermistor disk is held within the device so that it is interposed between conductive spring contact pieces and insulative position-alignment projections, which are cross-diagonally situated with respect to each other. The spring contact pieces are located further toward the periphery of the disk than the position-alignment projections, causing a spring force to extend in a direction generally outward relative to a direction perpendicular to the planes of the electrodes. In one embodiment, the position-alignment projections have cut-away portions at outer tip ends thereof respectively to further promote the formation of an open circuit state upon the occurrence of malfunction.
摘要翻译：在冰箱的电动机起动电路装置中使用的正的热敏电阻装置例如包括具有一对相对电极的正热敏电阻元件，每个相对电极接收从相应的一个弹簧接触构件弹性施加的压力，以将热敏电阻元件保持在设备中的预定位置。当热敏电阻器件被破坏时，元件破碎成碎片，其中一些与弹簧接触元件保持接触。剩余的片段偏离位置以确保它们不导电，导致打开状态，其中通过这样的碎片抑制任何电流。更具体地，正极热敏电阻盘被保持在器件内，使得它被插入导电弹簧接触片和绝缘位置对准突起之间，绝缘位置对准突起相对于彼此是交叉对角的。弹簧接触件比位置对准突起更靠近盘的周边，导致弹簧力相对于垂直于电极平面的方向大致向外延伸。在一个实施例中，位置对准突起分别在其外端部处具有切除部分，以在发生故障时进一步促进形成开路状态。

摘要： A method and apparatus for providing a more reliable protection device and an improved PIC power integrated switch. Accordingly, the over-temperature status of the switch as well as the overcurrent status of each of a plurality of ports of the switch are detected. If there is over-temperature, ports with the overcurrent status are identified as a potential cause. These ports are then switched off. After a predetermined waiting time period during which the switch temperature is expected to decrease, the over-temperature status of the switch is again checked. If the over-temperature disappears, then the ports with non-overcurrent status remain on. However, if the over-temperature persists, then all of the ports are turned off. The improved PIC switch thus increases the dynamic operation range of the conventional PIC switch, while ensuring normal operations.

摘要： A novel motor driver with an active snubber circuit. The motor driver is interposed between an external electrical power source and an electrical motor. The electrical motor is driven in first and second states such that the electrical motor produces an inductive flyback current when it switches torque direction. The motor driver comprises a reverse voltage protector in series between the power source and the electrical motor allowing flow of electrical power to the motor; and a capacitor arranged in parallel circuit with the motor between the motor and the diode (or other reverse voltage protector). The active snubber circuit is in parallel circuit with the motor between the diode and the electrical motor. The active snubber circuit comprises a switch having a sensor responsive to increases in the bus voltage resulting from the inductive flyback current and a resistor in series with the switch regulating electrical current flow.

摘要： A semiconductor module includes a housing with at least one semiconductor component that is conductively connected to at least one output line. An integrated temperature sensor is also housed in the housing. This sensor is connected, via at least one of its load terminals, to a terminal for receiving a supply potential. The temperature sensor conducts a load current that heats-up the temperature sensor when a first temperature threshold is crossed and a supply potential is in being supplied. A housed interruption device is arranged in such a way that it interrupts the output lines carrying the load current when a second temperature threshold has been exceeded.

摘要： Using the leakage current of the base resistance of the bipolar transistor, semiconductor integrated circuit device which detects an overheat condition of the elements protected from overheat, is realized. The overheat detection circuit and the elements or the circuits which might be protected from overheat, are formed on the same substrate. The said overheat detection circuit is comprised of a bipolar transistor, its base resistance, and a constant-voltage source. The constant-voltage source provides a certain voltage to isolate the elements. The joint base resistance is located close to elements or circuits which might be protected from overheat and located far from the constant-voltage source.
