摘要： A recording apparatus includes an image bearing or forming drum which is driven to rotate in a predetermined direction at constant speed. As the drum rotates, an image is formed on its peripheral surface electrostatically or electrophotographically. The image, developed or undeveloped, on the drum is then transferred to a transfer medium with the stiffness of the transfer medium being adjusted prior to the transfer. The drum has a diameter which is small enough for the transfer medium to be separated away from the drum by its own stiffness after image transfer, thereby allowing to dispose of an extra separating device and to make the whole apparatus compact in size and simple in structure.

摘要： A dual polarization transmission system for transmitting digital modulated signal each having a particular bandwidth by use of two polarized waves which have the same center frequency and are orthogonal to each other. The receiver side of the system demodulates radio frequency signals sent by a horizontally and a vertically polarized wave and coming in through a receiving antenna into IF signals. From the received signal of one polarization, an interference component of the other polarization generated on the basis of the cross-polar IF signal or demodulated signal is removed.

摘要： A color image recording apparatus for producing a composite color image on a paper sheet by developing electrostatic latent images formed on a photoconductive element, which is implemented as a belt, in different colors. The belt is supported and driven in a rotary motion by at least two rollers, i.e., a drive roller and a tension roller. The drive roller is fixed in place at a transfer station, while the tension roller is situated downstream of an exposure station with respect to the intended direction of rotation of the belt, i.e., at a developing station side. More specifically, the tension roller is so positioned as not to be effected by a change in the configuration of the belt ascribable to the selective content of developing rollers of individual developing units with the belt. The length of the belt as measured from the exposure station to the transfer station is maintained constant. The belt moves at the same speed at both of the exposure station and transfer station.

摘要： A color recording apparatus has an electric charge carrier which is circulatingly movable, an electrostatic latent image forming unit for forming a latent image which corresponds to an original image on the carrier, a development unit for developing the latent image; a transfer unit for transferring the developed image formed on the carrier to a record paper in a transfer process, a conveyor for conveying the record paper forward and backward with respect to the transfer unit, and a control unit which repeats control operations for controlling the latent image forming unit to form a latent image on the carrier, for controlling the development unit to develop the latent image, for controlling the conveyor to convey the record paper forward, for controlling the transfer unit to transfer the developed image to the record paper, and for controlling the conveyor to convey the record paper backward at least for one time. The control unit controls the conveyor prior to the transfer process so that the record paper is positioned at a point which is a predetermined distance before a transfer point and that a forward movement of the record paper is started on the basis of an information signal which is output in response to a state of starting an electrostatic latent image forming operation each time the transfer process is carried out.
