Abstract:
The present application provides a process for continuously producing 3-isothiazolinone derivatives and intermediate products thereof, comprising continuously carrying out four steps, i.e., sulfuration, purification, amination and chlorination. Compared with the batch process of the prior art, the process of the present application may reduce the amount of manufacturing devices, lower energy consumption, simplify operations, and is therefore particularly suitable for mass production.
Abstract:
A motherboard system includes a PCB, a CPU socket mounted on the PCB, a heat dissipating device, and a number of fastening devices. The CPU socket is configured for receiving a CPU. The heat dissipating device is mounted on the CPU socket for dissipating heat generated by the CPU. The fastening devices extend through the heat dissipating device and the CPU socket and are engaged in the PCB, thereby fastening the heat dissipating device, and the CPU socket to the PCB.
Abstract:
A thermal protection circuit includes a temperature detecting circuit, a comparing circuit, and a switching circuit. The temperature detecting circuit senses an internal temperature of the electronic device and outputs a voltage signal decreasing proportionally with the internal temperature of the electronic device increasing. The comparing circuit compares the voltage signal to a high voltage threshold or a low voltage threshold, thereby outputting a corresponding driving signal. The switching circuit turns on/off under the control of the driving signal.
Abstract:
The present invention discloses an optical disc drive including a pickup head for reading data from a disc; a spindle motor for supporting and rotating the disc; a loading/ejecting apparatus for loading or ejecting the disc; and an emergency ejecting apparatus. The emergency ejecting apparatus includes a slider for connecting the loading/ejecting apparatus, a rack, an elastic component for connecting the slider and the rack and a rotator rotated with the movement of the slider. When a user drives the rotator and the elastic component is elastically deformed, the slider is moved in the optical disc drive to drive the loading/ejecting apparatus to eject the disc.

Abstract:
One embodiment relates to a circuit for efficient wireless communication. The circuit includes a communication port adapted to be coupled to an antenna feed. Multiple communication paths stem from the communication port, where different communication paths are associated with different frequency bands. Multiple phase shift selection circuits are respectively associated with the multiple communication paths. The phase shift selection circuits have different respective impedances relative to the communication port and the respective impedances vary for the different frequency bands. Other methods and systems are also disclosed.

Abstract:
Provided are a method, system, and article of manufacture for a common configuration framework for applications to configure database objects and resources. Configuration interfaces are maintained for a plurality of different database types, wherein each configuration interface implements a database configuration operation with respect to a database of one database type. A configuration request is received from an application indicating a database type, database name, and a database configuration operation. A determination is made of one of the configuration interfaces for the requested database type to implement the requested configuration operation with respect to the database having the database name. The determined configuration interface is invoked with the requested database name to perform the requested configuration operation with respect to the database name.
Abstract:
Described is an aggregate computer system that operates by sharing devices of networked computing machines. A consumer machine uses a real device of a producer machine as a virtual device, by coupling the real driver of the real device over the network to a virtual driver of the consumer machine. Each machine may include an aggregate device manager that manages the virtual devices, and/or an aggregate connection manager that processes communications received over at least two different types of networks. Each machine may include a virtual bus and virtual bus driver that simulates a physical connection of a remote device to that machine via a bus. Upon receiving a request to plug-in a virtual device, the consumer machines queries for information of the device, and loads a virtual driver based on the device information when received. The consumer machine may query by sending plug-and-play events to the virtual bus.
