  • Toner for developing electrostatic images and method for producing the same
    Patent number: 8652724
    Abstract: The present invention is to provide a toner for developing electrostatic images having a low minimum fixing temperature, and high hot offset resistance and high heat-resistant shelf stability, and a method for producing the toner. Also, the present invention is to provide a toner for developing electrostatic images, comprising a binder resin, a colorant, a release agent and a retention aid, wherein the retention aid is a copolymer of 70 to 98% by weight styrene and 2 to 30% by weight (meth)alkyl acrylate, and the copolymer has a glass transition temperature of 5 to 60° C.
    Type: Grant

  • Random access system of a mobile communication system
    Patent number: 5689503
    Abstract: When data is transferred by using a plurality of time slots, the transferring period is shortened by adopting priority to assign the required number of slots. The base station BS which accepted packet P1 generates a "BUSY" signal and an echo at the final portion of the first time slot TS which begins at time t4. The base station BS, recognizing that there is a packet following the packet P1, generates a "RESERVED" signal at the final portion of the time slot TS which begins at time t5. The mobile station MS-A learns that the first time slot is assigned by recognizing the "BUSY" signal and the echo, and that the second time slot is also assigned by recognizing the "RESERVED" signal. Therefore, the first and second time slots are used successively for fast transferring.
