Abstract: A development device includes a development roller, a developer storage, a first rotating member, a second rotating member, and a rotation speed adjuster. The development roller carries a developer containing non-magnetic toner and magnetic carrier. The developer storage stores the developer. The first rotating member is provided in the developer storage at a position near the development roller. The second rotating member is provided in the developer storage at a position farther from the development roller than the first rotating member is. The first rotating member and the second rotating member agitate and convey the developer stored in the developer storage to supply the agitated developer to the development roller. The rotation speed adjuster adjusts a rotation speed of the second rotating member depending on an amount of new toner supplied to the developer storage. A development device includes a development roller, a developer storage, a first rotating member, a second rotating member, and a rotation speed adjuster. The development roller carries a developer containing non-magnetic toner and magnetic carrier. The developer storage stores ...more ...less

Abstract: In one embodiment, when a hot roller is driven to rotate, a driving gear rotates so that a swing gear and a swing cam rotate. Then, a sliding contact edge on the right side of a swing lever that abuts against the circumferential face of the swing cam repeatedly moves up and down, and the swing lever repeatedly rotates clockwise and counterclockwise with a shaft of a pressure release cam as the center. At this time, since only the clockwise rotation of the swing lever is transmitted via a one-way clutch to the shaft of the pressure release cam, the clockwise rotation is intermittently transmitted to the shaft of the pressure release cam. As a result of this, the pressure release cam intermittently rotates clockwise, and the pressure release cam pushes away a roller of a displacement frame, so that the pressure roller separates from the hot roller. In one embodiment, when a hot roller is driven to rotate, a driving gear rotates so that a swing gear and a swing cam rotate. Then, a sliding contact edge on the right side of a swing lever that abuts against the circumferential face of the swing cam repeatedly moves up and ...more ...less

Abstract: In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which information with respect to the network is written and sets a state in which a reception operation is performed during periods of time before and after the transmission of the beacon signal when performing access control not to make communication timing of a packet collide with that of another station by detecting a signal transmitted from another station. With performing such processing, a system can be formed based on minimum level of transmission and reception operation when transmission and reception data does not exist in each communication station in the network, and also a data transfer can be performed with latency as small as possible in a minimum necessary level of transmission and reception operation by making a transition of a transmission and reception state in accordance with a fluctuating volume of transmission and reception data. In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which ...more ...less

Abstract: Base stations and mobile devices have limited radio frequency spectrum through which they may communicate. Moreover, this spectrum is usually owned by a party having proprietary control. In order to allow for spectrum sharing, cognitive base stations (CBS) may be configured to select a radio frequency channel owned by another entity for its own use, and to determine how much additional noise it will create for such other entity. Based on this determination, the additional noise may be monetized, so that spectrum owners may be compensated for the additional noise created by use of their radio frequency channel.

Abstract: A system for single path processing identical, substantially identical, close or interfering frequencies with a single analog-to-digital converter. The system receives a plurality of input signals at various frequencies and front end circuits filter out first and second frequencies. A mixer and a front end oscillator are in communication with one of the front end circuits for mixing a front end frequency with one of the first and second frequencies prior to the analog-to-digital converter. A summer combines the output of the mixer with the output of one of the front end circuits. An analog-to-digital converter is connected to the summer for converting the analog input signal to a digital output signal. The first and second frequencies may be separately processed after they have been combined, even if they were identical frequencies.
