A communication apparatus 1 or 2 connected to a PBX 4 or 5 and an ATM network 3, is provided with a DTMF signal detecting portion 102 for detecting whether or not a DTMF signal is contained in a voice signal from the PBX 4 or 5, a DTMF signal monitoring portion 103, a DTMF cell generating portion 105 for coding and sending out a DTMF signal, a DTMF cell decomposing portion 110 for decoding a coded DTMF signal and a DTMF signal generating portion 113 for generating a DTMF signal on the basis of the information content of a decoded DTMF signal and sending out this DTMF signal to the PBX 4 or 5, and the transmission side communication apparatus 1 or 2 codes a DTMF signal in a specified form and transmits the DTMF signal and the reception side communication apparatus 1 or 2 decodes the coded DTMF signal and, on the basis of this content information, restores the DTMF signal in a DTMF signal generating portion 113. By doing so, even in case of transmitting a DTMF signal by means of a communication apparatus performing a voice code compression, it is made possible for a reception side communication apparatus (PBX) to judge/recognize the DTMF signal without error.

An image forming apparatus includes: an image forming portion for forming an image; a transferring material conveying belt for conveying a transferring material toward the image forming portion; a driving roller for driving the transferring material conveying belt; a driven roller over which the transferring material conveying belt is looped; and a transferring portion for transferring the image formed by the image forming portion to the transferring material. The transferring material conveying belt is wound and stretched between the driven roller and the driving roller. A rotational axis of the driven roller is different from a rotational axis of the driving roller. Further, a surface of the driven roller includes a layer which has a coefficient of friction lower than a coefficient of friction of a surface of the driving roller.

An image forming apparatus is disclosed. The image forming apparatus includes an image bearing member, a developing device, a gap retaining member and a control unit. The control unit decreases a potential difference according to an increase in the drive amounts of the image bearing member and the developer bearing member. The decrease is based on a difference according to an increase in at least one of the drive amounts of the image bearing member and the developer bearing member. The control unit is also configured to determine whether to execute a mode based on information about at least one of the driving amounts of the image bearing member and the developer bearing member from when the developing device is initially installed or the developing device is replaced.

Provided is an anisotropically conductive member that has a dramatically increased density of disposed conductive paths, can be used as an electrically connecting member or inspection connector for electronic components such as semiconductor devices even today when still higher levels of integration have been achieved, and has excellent flexibility. The anisotropically conductive member includes an insulating base and a plurality of conductive paths made of a conductive material, insulated from one another, and extending through the insulating base in the thickness direction of the insulating base, one end of each of the conductive paths protruded on one side of the insulating base, the other end of each of the conductive paths exposed or protruded on the other side thereof. The insulating base is made of a resin material and the conductive paths are formed at a density of at least 1,000,000 conductive paths/mm2.

A technique which improves the reliability in coupling between a bump electrode of a semiconductor chip and wiring of a mounting substrate, more particularly a technique which guarantees the flatness of a bump electrode even when wiring lies in a top wiring layer under the bump electrode, thereby improving the reliability in coupling between the bump electrode and the wiring formed on a glass substrate. Wiring, comprised of a power line or signal line, and a dummy pattern are formed in a top wiring layer beneath a non-overlap region of a bump electrode. The dummy pattern is located to fill the space between wirings to reduce irregularities caused by the wirings and space in the top wiring layer. A surface protection film formed to cover the top wiring layer is flattened by CMP.
