Title: Gas laser generator
Inventor: HOTATE TOORU
IPC: H01S3/22
Filed: 1982-08-11
Abstract: PURPOSE:To simplify the adjustment of axis-matching of a laser beam by a method wherein the titled laser generator is constituted in such a manner that it is coupled in M-form using a coupling tube provided with a fixed reflection mirror and a freely moving reflection mirror on both ends so that a beam of light is reflected at an acute angle at each end of a plurality of resonant tubes which are arranged in parallel, thereby enabling to reduce the length of the entire device and to make the device smaller in size. CONSTITUTION:A high voltage is applied to the mixed gas supplied to resonant tubes 11A and 11B, the carbonic acid gas molecule in the gas is excited, the generated beam of light passes both resonant tubes 11A and 11B through the intermediary of a coupling tube 12, the beam of light is amplified by performing a reciprocating movement in these tubes repeatedly and radiated from a semitransparent mirror 5 as a laser beam. In this case, as reflection mirrors 13 and 14 are installed on both sides in such a manner that they are attached close to an electrode, the space corresponding to the deadspace of the conventional device can be reduced. Aslo, as the mirrors 13 and 14 are installed in fixed state and the mirror 15 is movably installed, the angle of incidence and reflection can be adjusted freely and also the acute angle can be obtained for incidenting and reflecting beams of light, thereby enabling to perform the axis-matching of laser beam between the mirrors 13-15 relatively easily.

Abstract: PURPOSE:To improve the registration accuracy of monochromatic toner images and to improve images by setting the number of teeth of a belt to which driving power is transmitted on a photosensitive drum side at integer times the number of teeth of a belt which transmits the driving power on a driving device side. CONSTITUTION:The rotational driving power of a DC servo motor 81 is transmitted via gears G1-G5 to a toothed pulley G6. The driving power is transmitted from the pulley G6 to a toothed pulley G40A of the photosensitive drum 40 by an endless toothed 2nd belt 85 to rotationally drive the photosensitive drum 40. The number of teeth of the pulley G40A on the drum 40 side is set at integer times the number of teeth of the pulley G6 on the driving side. For example, the pulley 6 rotates 5 turns with respect to one turn of the pulley G40A and thereafter, the same teeth face each other via the 2nd belt 85 if the number of teeth of the pulley G40A is 80, the number of teeth of the pulley G6 is 16 and the number of teeth of the 2nd belt 85 is 160. The monochromatic toner images superposed on the photosensitive drum are, therefore, registered with good accuracy and the quality of the images is improved.

IPC: G01R25/00
Filed: 1991-06-12
Abstract: PURPOSE:To cut unnecessary data and to make it possible to secure the ROM region by that amount by adding the offset value of each region to the numerical value obtaining by series expansion at the divided region of an angle whose phase is shifted, and computing the phase. CONSTITUTION:A phase-shift operating part 11 obtains the phase-shifted value x=Sin (theta-K') by using Sin theta and Cos theta and an arbitrary phase angle K'. An offset-value determined part 12 determines the offset value K at each phase- shifted value and stores the value in a ROM 20. A series expanding part 13 expands the series within the rage of 0 degree <=x<=30 degrees in the divided regions of 0 degree <=x<=30 degrees, 30 degrees <=x<=60 degrees and 60 degrees <=x<=90 degrees by using each phase-shifted value (x) with, e.g. the phase angles K' as 0 degree, 30 degrees, 60 degrees and 90 degrees. Thus, the expanded value Sin<-1>x is obtained. In an adding part 14, the phase is computed by adding the offset value k in each region, which is determined for every region, to Sin<-1>x.
