Title: Image forming device
Inventor: CHIBA NORIYOSHI
IPC: B41J2/395
Filed: 1989-01-10
Abstract: PURPOSE:To obtain a clear image having no omission by regulating the carrying system for imaging member such that contact between an electrode and the imaging member can be maintained continuously with such tensile force as the imaging member is not crumpled. CONSTITUTION:An imaging member 1 is carried, in the direction of an arrow 2, with constant speed and carrying angle of theta where the sum (T+f) of the tensile force T of the imaging member and frictional force (f) exists, in the relation of action and reaction, around the contact 5 of the imaging member 1 and an electrode 4 between the imaging member 1 and an electrode head 3. The tensile force is applied mechanically in order to stretch the imaging member properly and to maintain contact between the imaging member 1 and the electrode 4 while the frictional force (f) is produced through rubbing of the imaging member 1 and the electrode 4 during carriage of the imaging member 1. theta is set larger than 20 deg. and T is set larger than 3% of the breakdown strength of the imaging member. Since such force as sufficient for keeping contact between the electrode and the imaging member without crumpling the imaging member functions between the electrode and the imaging member, omission of image due to insufficient contact can be eliminated.

A large number of rays that have λ1 to λn narrow spectra is acquired, when it is passed through a comb-lien filter 4 that has a transmission band in a certain interval. A large number of intervals of the light beams, i.e., light beam widths of a spectrum are decided by the characteristic of the filter 4. The filter 4 closely performs temperature control to stabilize the wavelength of a passing area. An optical fiber amplifier B5 amplifies each optical spectrum after the filter 4. After dividing filters 6 and 8 divide the multiple beam light into λ1 to λ2 light beams. external light modulators 7 and 9 perform intensity modulation of each light beam, composites it and generate wavelength multiple light beams.

The variable delay circuit 22 delays the observation signal by the time corresponding to the position in the time base direction of the gate line L and applies the output to a multivibrator 23. AND between the output of the multivibrator 23 and the trigger signal from a trigger circuit 71 is operated.

IPC: H02M1/12
Filed: 1993-01-14
Abstract: PURPOSE:To prevent flicker of fluorescent lamp by correcting the phase lag of sine waveform to be detected by an output voltage detecting means thereby obtaining an output voltage waveform and then determining the reference point of sinusoidal output voltage from a power supply based on a zero-cross point. CONSTITUTION:Output voltage 11 from a power supply is detected by a sinusoidal output voltage detector 12 and the phase lag thereof is corrected by a corrector 14 thus producing an output 15. A detecting section 16 detects a zero-cross of the output voltage 15 and a reference sine wave generator 18 generates a reference sine wave 19. A command value 22 from an output voltage command controller 21 is multiplied 23 by the reference sine wave 19 and added to a phase corrected output 15 thus obtaining a difference 26 which is then fed to a feedback controller 27 where a predetermined phase command 28 is determined. The phase command 28 is fed to a converter 29 of inverter constitution and the output voltage 11 therefrom is employed as the power supply for a fluorescent lamp. This constitution prevents flicker of fluorescent lamp effectively even when a compressor in an electric vehicle operates.
