摘要： In transmitting a plurality of data arranged in a time series of a first period (T), there is formed, every predetermined second period (SF) longer than the first period (T), a packet containing a plural number (x) of data supplied within a given cycle of the second period (SF). At that time, one data is specified from among every group consisting of a fixed number (M), not smaller than two, of the data, and time information indicative of a time position of the specified data is attached to the packet which the data belong to. A receiving-end unit reproduces the data, by reproducing the respective time positions, i.e., the first period (T), of the individual data on the basis of the time information contained in the received packet.

摘要： The present invention includes an interface apparatus in a node of a communication network for synchronizing internal time data of the node to reference time data of the communication network during transfer of a data train having a time-sequential arrangement through the communication network. The interface includes a receiving device that receives the reference time data transmitted from another node such that the reference time data has a first time resolution to maintain the time-sequential arrangement of the data train. An internal oscillating circuit generates a clock signal to provide a second time resolution, and a counting device counts the clock signal having the second time resolution to successively produce count data having a higher order bit part, which corresponds to the reference time data, and a lower order bit part. Also provided is a synchronizing device that operates to reset the counting device to adjust all bits of the count data in sync with the reference time data, and retrieves the higher order bit part of the adjusted count data to provide the internal time data.

摘要： Laser light, emitted from a laser light source, is formed into a converged light ray by a condensing lens, and deflected by a resonance mirror. The laser light that has been deflected is converged on a photosensitive member through a scanning lens. The scanning lens is constituted of one negative lens, and has at least one nonaxisymmetric face that provides the same power in the vicinity of the light axis in both of a main scanning direction and a sub-scanning direction. With this arrangement, even when a deflection angle in the resonance mirror is small, it is possible to shorten a distance from the resonance mirror to the photosensitive member, which is required for providing a desired scanning width. Moreover, it becomes possible to effectively carry out image-face curvature correction and groove-shaped aberration correction within a sub-scanning cross section and, also, to reduce the size of its own unit including the resonance mirror and the scanning lens. Consequently, a small-size laser scanning device with high precision can be achieved.

摘要： A plane mirror is disposed in an optical path after a polygon mirror which deflects laser light. Incident light to and reflected light on the polygon mirror has no angle in an auxiliary scanning direction and the polarization direction of laser light is inclined relative to a plane (deflection plane) including the incident light to and the reflected light on the polygon mirror. An inclination angle and inclination direction of the light deflection direction of the laser light, an inclination angle of the plane mirror are configured so as to satisfy predetermined conditions. With such a configuration, a change in reflectance on the polygon mirror accompanying a change in deflection angle can be cancelled or alleviated by a change in reflectance on the plane mirror accompanying the change in deflection angle, and a difference in light quantity distribution on a photosensitive member on the left and right sides thereof is alleviated in comparison with a difference in reflectance to be caused by the polygon mirror.
