Abstract: A mold frame is formed with two collision sections opposed to a back face of a movable iron core with a movable contact support therebetween. One collision section is higher than the other. The movable contact support includes an inclined plane on the base bottom face thereof and near the higher collision section. The base bottom face abuts the back face of the movable core. When this contactor is attached with the higher collision section provided at the lower side, the support having collided in the “released” condition is rotated around the collision section, thereby reducing the impact. When this contactor is attached with the lower section at the lower side, the support attracted toward the core by a plate spring is allowed to collide, at the bounce of the support, with the back face of the core via the inclined plane, thereby canceling the inertia by the bounce.

Abstract: A switching power converter for converting an AC power into a DC power. The converter includes a transformer, a charge storage unit, a synchronization signal generator, and a switch element. The transformer includes a primary side coil and a secondary side coil, and the primary side coil generates an induced voltage at the secondary side coil according to AC power. The charge storage unit charges according to the induced voltage and outputs a DC power. The synchronization signal generator generates a synchronization signal according to the induced voltage. The synchronization signal is the first value when the induced voltage is positive and is the second value when the induced voltage is negative. The switch element, serially connected to the secondary side coil and controlled by the synchronization signal, is turned on when the synchronization signal is the first value and is turned off when otherwise.

Abstract: A current detecting device and method that detects a variation in a current being supplied to a load in supplying variable DC power to the load via an inductor from a synchronous rectification DC-DC converter in which a high-side switch is connected to one electrode of a DC input voltage source and a low-side switch connected to the other electrode. The switches are turned on and off alternately during a prescribed switching period. A low-pass filter is connected to a signal line that leads from a connecting point of the inductor and the switches. An operation circuit detects an output current of the DC-DC converter by performing an operation on the difference between an output voltage of the low-pass filter and an output voltage of the DC-DC converter.

Abstract: A DC/DC converter capable of preventing abnormal temperature increase in a power transistor. The DC/DC converter comprises a loop circuit, a power transistor, an abnormal high temperature detection circuit, and an abnormality processing circuit. The power transistor supplies an electric current to the loop circuit according to a control pulse signal. The loop circuit accumulates electromagnetic energy in an inductor when the electric current is supplied and generates a negative DC voltage by causing a loop electric current to flow by using the electromagnetic energy accumulated in the inductor when no electric current is supplied. The abnormal high temperature detection circuit detects a normal/abnormal state of temperature of the power transistor. The abnormality processing circuit switches the power transistor off when the abnormal high temperature detection circuit has detected that the temperature of the power transistor is abnormal.

Abstract: A blade server management system with an auxiliary management structure is described. The system has at least two management boards and a connecting base. The two management boards become one master management board to control directly the system and a slave management board standing by to take over system control according to a predetermined timing to detect heart beat signals and the inserted positions on the connecting base. A first COM port is a main interconnecting line between the management boards, and a LAN port is an auxiliary interconnecting line. A local computer connecting with a second COM port is utilized auxiliary to control the management system. The slave management board is promoted to master management board status when the original master management blade fails. Therefore, the system stability can be increased.

Abstract: A method and apparatus for accessing a non-symmetric dual-slot address table having two entries 0, 1 that are different in size. When writing data, the data is hashed to generate a hash value. Then, the data is written to a slot corresponding to the hash value in the entry 0. When there was data in the slot 0, the hash value is mapped to a sub-address and a share value, and then a slot 1 corresponding to the sub-address is selected from the entry 1. Afterwards, the SMAC tag, the share value and the source port are written to the slot 1. In addition, when transmitting the packet, a hash value is generated according to the DMAC address. Then, a SMAC tag, the share value and the source port are read according to the hash value. After compared, the packet is transmitted.
