Title: Fixing device
Inventor: ARAAKI SATORU
IPC: G03G15/20
Filed: 1994-10-06
Abstract: PURPOSE: To prevent reduction in image quality due to reverse transfer of foreign matters stuck to a cleaning roller by bringing detachably the cleaning roller into press-contact with an oil coating roller in contact with heating roller. CONSTITUTION: Toner is fixed to a recording paper sheet by heat by bringing a pressurizing roller 2 into press-contact with a heating roller 1 and passing a recording paper sheet P on whose surface toner is transferred between both rollers. An oil coating roller 3 is bought into press-contact with the heating roller 1 with silicone oil impregnated therein, driven to be rotated and supplies oil and a cleaning roller 4 structured in attachable to and detachable from the oil coating roller 3 is rotated along with the roller 3 in contact therewith to remove foreign matters and it is detached from the roller 3 when fixation is completed.  Thus, since during non-fixing operation, the cleaning roller 4 is not brought into press contact with the oil coating roller 3, foreign matters, once removed, are prevented from reversibly flowing through the oil coating roller 3, the heating roller 1 and the recording paper sheet P in this order.

Title: Level shift circuit
Inventor: KEISU ESU TEIRAA
IPC: H03K5/003
Filed: 1988-10-25
Abstract: PURPOSE:To shift the level of a difference signal without giving any effect on an amplitude of the difference signal by outputting the difference signal subject to offset from the 1st and 2nd output terminals of a current mirror. CONSTITUTION:Common connecting points (nodes) of output terminals of a current mirror 10 and terminals of dual clamp circuit 12 are noninverting and inverting output terminals. Moreover, a reference terminal of the dual clamp circuit 12 connects to a bias terminal of the current mirror 10. The dual clamp circuit 12 prevents one voltage of the noninverting and inverting output terminals from getting higher than a prescribed reference value. A voltage decrease of the low difference input signal varies the voltage of the other output terminal by a quantity corresponding to the entire differential voltage between input terminals in relation to the operation of the current mirror 10 by the maximum voltage of the output clamped to the reference value. Thus, the reference level of the differential signal appearing at the noninverting and inverting output terminals is shifted but the amplitude of the output signal is equal to the amplitude of the input signal.

Filed: 1987-10-28
Abstract: PURPOSE:To set optimum process conditions in steps by measuring the intensity of the reflected interference wave of an incandescent light during an etching step, obtaining the remaining film thickness, and controlling it. CONSTITUTION:An incandescent light is irradiated to a film to be etched of a wafer 4 from a light source 13 simultaneously upon starting of etching, and its reflected light is detected by a photodetector 16. A signal of reflecting intensity from the detector 16 is input to a remaining film calculator 17, and compared by a comparator 17a with a threshold value of 1.3 times as large as the reflecting intensity immediately after the etching set by the comparator 17a is started. The peak points at the upper and lower sides exceeding the threshold value and the film thickness at that time point from the refractive index are obtained through a predetermined calculation. Further, the end of the etching can be detected by the time point when the timing change rate of the reflecting intensity becomes zero. Thus, an alarm unit 17c, an indicator 17d are operated, a high frequency power source 5 is controlled, and a monitor is set to optimum processing conditions.
