20100074164 | Communication Systems - A method for transmission of information about downlink and uplink parameters of a intermediate apparatus link in a multi-hop wireless communication system, the system comprising a first node apparatus, a second node apparatus and one or more intermediate apparatuses, each said apparatus being operable to transmit and receive information along a series of links forming a communication path for downlink and uplink communication, the communication path extending between the first node and second node apparatuses via the or each intermediate apparatus, each link comprising either a first node link between the first node apparatus and a said intermediate apparatus or an intermediate apparatus link between a said intermediate apparatus and a said apparatus which is not the first node apparatus, and the system having access to a minimum allocation unit for allocating time and transmission frequency bandwidth, the method comprising: obtaining values of downlink and uplink parameters for a particular intermediate apparatus link; mapping both values onto a single minimum allocation unit and transmitting them towards the first node apparatus. | 03-25-2010 |
20110222923 | IMAGE FORMING APPARATUS - A heating device includes a fixing member; a pressure member that comes in pressure contact with a surface of the fixing member; and a cleaning web unit. The cleaning web unit includes a contact roller that contacts the pressure member via a web that is impregnated with a lubricant agent, a supplying roller that supplies a new web, a roll-up roller that rolls up and retrieves the web that has been used for wiping off adhering matter from the pressure member, and a lubricant agent absorption member that absorbs the lubricant agent by contacting the web at a web path extending from the supplying roller to the contact roller. | 09-15-2011 |
20110229224 | Fixing unit and image forming apparatus using fixing unit - Disclosed is a fixing unit including a fixing member; a pressure member brought into press-contact with a front surface of the fixing member; a pressure mechanism that changes a position at which the pressure member is brought into press-contact with the fixing member, the pressure mechanism being capable of controlling a presence or absence and a width of the nip part; and a cleaning web unit having a contact roller brought into contact with at least the pressure member via a web, a supply roller that supplies a new web, and a winding roller that winds and collects the web having wiped off an attachment on the pressure roller. The contact roller is caused to move following a movement of the pressure mechanism to maintain a constant contact position, a constant contact direction, and a constant contact force thereof with respect to the pressure member. | 09-22-2011 |
20120269532 | Fixing Device And Image Forming Apparatus Incorporating Same - A fixing device includes a moving assembly that moves a second rotary body and an airflow guide between a first position and a second position, the first position where the second rotary body contacts a first rotary body to form a fixing nip therebetween through which a recording medium bearing an unfixed toner image is conveyed and a constant first interval between the second rotary body and the airflow guide is smaller than a variable second interval between the second rotary body and an exhaust duct, the second position where the second rotary body is isolated from the first rotary body and the constant first interval between the second rotary body and the airflow guide is equivalent to the variable second interval between the second rotary body and the exhaust duct. | 10-25-2012 |
20130216250 | DEVELOPMENT DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME - A development device includes a developer bearer to carry by rotation developer to a development range facing a latent image bearer, and a developer regulator to adjust an amount of developer transported to the development range by the developer bearer. Multiple projections are formed in a surface of the developer bearer, and the developer bearer rotates in a reverse direction to a direction of rotation for image development while image development is not performed. The developer regulator includes a blade having a first end held by a regulator holder and a second end that contacts the multiple projections formed in the surface of the developer bearer and is disposed in a direction counter to the direction of rotation of the developer bearer for image development. | 08-22-2013 |
