  • Patent number: 10624067
    Abstract: A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.

  • Patent number: 10616874
    Abstract: A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.

  • Patent number: 10577462
    Abstract: The present invention relates to a production method of polyalkylene carbonate particles capable of precipitating and separating resin particles from a polyalkylene carbonate suspension obtained through polymerization of an epoxide and carbon dioxide. According to the present invention, the production method is capable of obtaining a polyalkylene carbonate resin having excellent workability with a high yield and a low energy cost while reducing a scale of a facility, a processing time, and a wastewater amount, as compared to conventional methods such as a flash separation method.

  • Publication number: 20140377453
    Abstract: The present invention relates to an insulating adhesive composition for metal printed circuit board, an adhesive-coated metal plate using the same, and a method for manufacturing the adhesive-coated metal plate. The adhesive composition according to the present invention forms an adhesive layer that is excellent in terms of adhesion to a copper foil, electrical insulating properties, and thermal resistance. The composition contains a specific epoxy resin, a curing agent and alumina. According to the present invention, in coating the metal plate with the solvent type adhesive, a roll coating method is used to perform a continuous coating process on the metal plate, thereby improving productivity when compared to the general method using a sheet type adhesive film.

  • Patent number: 6679721
    Abstract: The present invention is a module insertion tool for anchoring a module to a motherboard. The module insertion tool has two drivers on either side of the tool that operate independently of each other, and help in anchoring the module to the motherboard. There is a knob built into the tool. The knob is connected to a chain that turns the drivers until a preset torque value is reached. The two drivers built into the tool are independent of each other and each driver turns until the preset torque value has been reached. This preset torque value can be obtained by either manually turning the knob, or by attaching an electric source to a socket built into the knob. There are three locators on a bottom plate of the tool that help in the alignment of the module to the tool, and there are locking pins on each driver that hold the module stationary while the module is being anchored to the motherboard by the drivers of the tool.

The module insertion tool has two drivers on either side that operate independently of each other, and help in anchoring the module to a motherboard. There is a knob that is connected to a chain that turns the drivers until a preset torque value is reached. Since the two drivers are independent of each other, each driver turns until the preset torque value on its side is reached.
