摘要： When a client sends an RPC request that requests a server for a service, the client adds identification information to the RPC request. When an active server receives an RPC request, it stores the identification information thereof in a stable area that is not destroyed even if a defect takes place in the client or the server, and executes the requested service. When a defect takes place in the active server, the backup server takes over the process of the active server. A PALIB of the backup server compares the identification information of the RPC request re-sent from the client with the identification information in the stable area. When they match, the PALIB determines that the RPC request is redundant. The backup server performs a redundant process and sends back the correct result to the client.

摘要翻译： 当客户端发送请求服务器进行服务的RPC请求时，客户端将标识信息添加到RPC请求。 当活动服务器接收到RPC请求时，即使在客户机或服务器中发生缺陷，也将其识别信息存储在不破坏的稳定区域中，并且执行所请求的服务。 当活动服务器发生缺陷时，备份服务器将接管活动服务器的进程。 备份服务器的PALIB将从客户端重新发送的RPC请求的识别信息与稳定区域中的识别信息进行比较。 当它们匹配时，PALIB确定RPC请求是冗余的。 备份服务器执行冗余处理，并将正确的结果发送给客户端。

摘要： A DC-DC converter prevents through current from flowing in an output transistor. A first transistor receives an input voltage. A second transistor is connected to the first transistor. A comparator is connected to the second transistor. The comparator detects current flowing through a choke coil based on the potential difference between two terminals of the second transistor to generate a switching control signal for turning the second transistor on and off. The second transistor and the comparator form an ideal diode. A control circuit of the DC-DC converter generates an activation signal for turning the first transistor on and off based on a pulse signal to keep an output voltage constant. A through current prevention pulse generation circuit generates a pulse signal for turning off the second transistor from before the first transistor is turned on to after the first transistor is turned on.

摘要： In an input transistor of current mirror circuit, it is intended to prevent the current generated by Early effects from appearing in the output current of the current mirror circuit. Having an Early voltage detector 22 of same connection and structure as a driver circuit 21, and connected in parallel to the driver circuit 21, the current flowing in input transistor Q9 of the Early voltage detector 22 is detected. Output current (current IQ11) of Early voltage detector 22 is added to input current (current IQ5) of driver circuit 21. As a result, in input current (current IQ7) of current mirror circuit 25, current α due to Early voltage effects can be canceled. At the same time, current α due to Early voltage effects generated in input transistor Q5 of current mirror circuit 25 is prevented from appearing in output current (current IQ8) of current mirror circuit 25.

摘要： A control circuit for a DC-DC converter that prevents a deficiency from occurring due to sudden interruption in power supply. The control circuit activates and inactivates a main switching output transistor and a synchronous rectification output transistor to convert the input voltage to an output voltage. The output voltage is smoothed by a smoothing capacitor. When the input voltage decreases, the control circuit activates the synchronous rectification output transistor to readily discharge the smoothing capacitor via the synchronous rectification output transistor.
