Abstract:
PROBLEM TO BE SOLVED: To provide a communication system capable of automatically performing network division as necessary by which at least two communication terminal apparatuses mutually performing communication can exist in the same network. SOLUTION: A video terminal apparatus and a TV terminal apparatus in the communication system include a network setting part for setting the SSID of a belonging network. The video terminal apparatus also includes a network change determining part for determining whether the belonging network is changed in response to a prescribed condition or not. When the network change determining part of the video terminal apparatus determines that the belonging network is to be changed, the network setting part of the video terminal apparatus generates the new SSID and the generated SSID is reported from the video terminal apparatus to the TV terminal apparatus. Consequently, the network setting parts of the video terminal apparatus and the TV terminal apparatus set the new SSID, so that the video terminal apparatus and the TV terminal apparatus are shifted to another network.

Abstract:
PROBLEM TO BE SOLVED: To provide a wireless communication apparatus which can switch a transmission line speedily in response to the change of a radio environment, and to provide a wireless communication method, a wireless communication system, a program and a storage medium in which the program is stored. SOLUTION: When a transmitter station 102 is authorized to perform transmission, it acquires transmission line characteristic information of a first transmission line 104 and transmission line characteristic information of a second transmission line 105 and selects a transmission line to be used for transmitting a frame to a receiver station 103 based on the transmission line characteristic information of the first transmission line 104 and the transmission line characteristic information of the second transmission line 105. Each time the predetermined number of frames are transmitted before the lapse of a term specified in the transmission authority after the selection of the transmission line, the transmission line to be used for transmitting the frame to the receiver station 103 is selected based on the acquired transmission line characteristic information of a non-selected transmission line and newly acquired transmission line characteristic information of a selected transmission line.

Abstract:
PROBLEM TO BE SOLVED: To provide a non-magnetic one-component development apparatus that can form images of high quality for a long period of time without causing aggregation and liquidity degradation of toner, filming of toner to a developing roller and photoreceptor, toner-fusion to a control blade, and image defects such as ground fog, void, fading or the like. SOLUTION: In the non-magnetic one-component development apparatus 4, a developing roller 5 uses elastic materials with spring hardness of Hs (A) 45-65°, and a feed roller 7 uses foams of continuous closed-cell foam rubber materials having not less than 400/cm 2 in the number of unit cell and not more than 500 μm in the cell diameter. Further, the toner stored in a developer tank 9 uses toner particles containing binder resins and coloring agents that are externally added with inorganic fine particles of 250-600 nm in an average primary particle size.

Abstract:
PROBLEM TO BE SOLVED: To suppress an increase in communication quantity caused by an ACK frame while securing accuracy in a data reception in a receiving station which requires accuracy in the reception of data. SOLUTION: Each of receiving stations 200-203 is capable of implementing reply processing for redirecting the ACK frame. The data transfer method includes: a setting step for setting whether or not reply processing is to be performed for each of receiving stations 200-203; a transmitting step for transmitting data by a transmitting station 100; a receiving step for receiving the data by the receiving stations 200-203; and a discriminating step for discriminating whether or not reply processing is to be performed based upon setting by a setting part of the relevant receiving station by an ACK control part of any one of receiving stations 200-203 which receives the data. The receiving stations 200-203 are classified into predetermined receiving station groups 300-303 and it is set whether or not reply processing is to be performed in the receiving station of a group for each group.
