摘要:
A laser recording apparatus wherein an image is recorded by laser beam scanning, and a stop amount of a stop is varied in accordance with recording magnification. The stop is disclosed at a position whereat it can vary the beam radius of a laser beam incident in a focusing lens. The optical intensity of a laser beam is varied in accordance with the recording magnification.

A semiconductor laser driver is designed to detect a semiconductor laser output and control a drive voltage or current of a semiconductor laser so as to set a detected laser output to be a predetermined constant laser output. The laser driver includes an integrator for integrating the detected laser output, thereby utilizing an integrated signal as a semiconductor laser drive signal. The integrator integrates the difference between a voltage corresponding to the detected laser output and a reference voltage corresponding to the predetermined constant laser output.
摘要:
A light beam recording system in which the beam is deflected after passage through a focusing element to scan a recording medium. An optical image surface correction system is employed between the deflector and recording medium for correction of the curvature of the field in the main scanning direction. The optical correction system includes an aspherical surface and deviation from a paraxial generating spherical surface to the aspherical surface.
摘要:
A seimconductor laser device wherein the quantity of light emitted from a semiconductor laser is monitored by a light quantity monitor circuit, and the output of the monitor circuit is compared by a comparator circuit with a reference voltage. An emission inhibiting device inhibits the semiconductor laser from emitting light in accordance with the output of the comparator circuit. The emission inhibiting device is arranged to inhibit the supply of an optical modulation signal to the semiconductor laser, or it comprises a current source for driving the semiconductor laser, the output of the current source being reduced when the emission of light from the laser is to be inhibited.
摘要:
An image recording apparatus having a beam scanning optical system using a deflector having a deflecting member, wherein a resilient member is interposed between the optical system including said deflector and an image forming portion. The resilient member is made of a viscous resilient elastomer of low hardness.
摘要:
A laser recording apparatus wherein a laser beam modulated in accordance with image signals and deflected by a deflector having a deflecting element in a predetermined direction scans a recording medium through a beam correcting lens system interposed between the deflector and the recording medium to write in the image signals on the recording medium. The deflecting element of the deflector is molded integrally of a frame, a reflecting mirror, a drive coil and a ligament. The deflecting element is made of a crystal base.

A system for and method of supporting preparation of an operation schedule table for a development project, including an input accepting section for accepting, for each of a plurality of components to be developed, an input of a utilization method by which a first development project having a timetable already prepared is used in a second development project for which a new timetable is generated; a plan conversion section for converting, for each of the components, a plurality of operation processes planned in the first development project based on the utilization method for each of the components, to generate a plurality of operation processes for developing the components in the second development project; and a schedule section for scheduling the respective operation processes to generate a timetable for the second development project.
摘要:
A communication apparatus includes a data communication unit; a speech communication unit; a connection unit for connecting to a plurality of lines; and a switching unit for selectively connecting the data communication unit and the speech communication unit to any one of the plurality of lines. Both speech and data communication units may be used concurrently. The communication apparatus further includes a memory unit for storing line information identifying a line different from another line in use for data communication or speech communication. An automatic calling to both speech and data communication units may be effected by a single calling operation by the operator.
摘要:
A recording apparatus has a plurality of erasing heads arrayed aslant to the direction in which a strip-like recording medium is to be transported. An erasing operation on recorded information on the recording medium obliquely begins and obliquely ends by switching the erasing heads on and off one after another along an oblique recording track on the recording medium to accomplish information editing without introducing noises.
