Title: Stereomicroscope
Inventor: NAKAMURA SHINICHI
IPC: G02B21/02
Filed: 1993-11-05
Abstract: PURPOSE:To provide the microscope having an objective lens which is variable in working distance, lessens the degradation in magnification and the degradation in a stereoscopic feel by forming the face furthest from an object of an objective optical system as a face concave on eye side. CONSTITUTION:The mentioned above objective lens consists, successively from an object side, a negative lens group and a positive lens group and the face on the extreme eye side thereof is the concave face. The working distance is changed by changing the optical path length spacing d3 between the negative lens group and the positive lens group. The lens is so formed that the spherical aberrations and chromatic aberrations generated by the face having the positive power of the positive lens group are negated by the spherical aberrations and chromatic aberrations generated by the joint faces of the positive lens group. The lens is also so constituted that the spherical aberrations and chromatic aberrations generated by the faces exclusive of the joint faces of the negative lens group are negated by the spherical aberrations and chromatic aberrations generated by the joint faces of the negative lens group and that the residual aberrations of these aberrations in both lens groups are negated by each other. As a result, the focal length of the objective optical system is made smaller than the working distance and the overall magnification and the stereoscopic feel are increased.

Title: Printer mechanism and controller
Inventor: YAMADA MASAHIKO
IPC: B41J29/13
Filed: 1990-11-05
Abstract: PURPOSE:To easily set a rolled sheet by moving a rolled sheet guide plate when the sheet is set to block a single slip sheet passage, and driving power means to set the sheet to a feeding state. CONSTITUTION:A knob 16 is fixed to one end of a rolled sheet guide plate 6, and the other end is opposed to a slip sheet passage. The knob 16 is pressed in a direction of an arrow 6A to block between a slip sheet drawing roller 3 and a slip sheet draw suppressing roller 5, thereby obtaining a rolled sheet passage. In this case, the operation of the knob 16 is detected by a detector 8 fixed to a rolled sheet guide plate mounting frame 9, and a detection signal is used as a signal for starting a sheet feeding power source. Thus, a rotary force transmitted from the source rotates a rolled sheet feed roller 10 in a direction of an arrow 10A. The started roller 10 is bought into pressure contact with a rolled sheet 15 inserted from the direction of the arrow 15A with a rolled sheet retaining roller 11 to start feeding the sheet 15.

Title: Optical signal output device
Inventor: FUJISAWA TAKANORI
IPC: H04B10/03
Filed: 1986-12-15
Abstract: PURPOSE:To approximately completely prevent an optical signal from being broken at the time of switching to reduce the influence upon a system by outputting the output of a signal switch to the other optical signal output circuit normally set to the stand by state when one current circuit becomes abnormal and is switched to a spare output circuit in the cold stand-by state. CONSTITUTION:An electric signal is inputted to an optical signal output circuit 5 from an input terminal 10 through a signal distributor 3 and a signal switch 7 in the state where the optical signal output circuit 5 is used, and the signal is converted to an optical signal by the optical signal output circuit 5 and is transmitted from an output terminal 11 through optical couplers 8 and 4. If abnormality occurs in the optical signal output circuit 5, a control circuit 9 controls an optical signal output circuit 2 and controls the signal switch 7 so that the output of the signal switch 7 is outputted to an optical signal output circuit 6 for the time required for stabilization of the output of the optical signal output circuit 2. The optical signal is broken only for the time, when the signal switch 7 is operated, during this operation and this time is very short, and the system is very little affected by the break of the signal.

Title: Color image forming device
Inventor: HAYAKAWA SHINJI
IPC: G03G15/16
Filed: 1994-12-02
Abstract: PURPOSE: To provide a color image forming device which is free from the occurrence of color slippage in the hue of a color image. CONSTITUTION: Separate toner images of different colors are formed on an image formation carrier and the toner images are transferred to an intermediate transfer medium 11 in order, thereby forming color toner images to the medium 11, and the color toner images are transferred all at once to a recording medium 12 by the use of a secondary transfer means, and thus the color image is formed on the recording medium 12. The secondary transfer means is a transfer roller 27 and its resistance value is 10<8> Ω or higher.  This eliminates the need to control minutely a secondary transfer voltage or a secondary transfer current, and therefore makes it possible to obtain the same batch transfer efficiently in its monochromatic part and intermediate-color part at the same time irrespective of the resistance value of the intermediate transfer medium 11 and the thickness of each toner layer. As a result, color slippage is prevented from occurring in the hue of the color image.

Abstract: PURPOSE:To prevent the occurrence of an abnormal image with a separation guide by alternately arranging a first separation guide and a second separation guide so that the gap of the second separation guide is positioned at the conduc tive discharging wire part of the second separating charge wire. CONSTITUTION:The separation charge wire 102a is arranged on the conductive discharging wire, the separation charge wire 102b is arranged on an insulating wire, and the conductive discharging wire part is arranged at a prescribed interval thereon. The separation guide 104a and the separation guide 104b are alternately arranged, and the gap of the separation guide 104b is disposed so as to be positioned at the conductive discharging wire part on the separation charging wire 102b. Therefore, while a transfer paper passing on the separating charger 100, whole faces of transfer paper, that is, the whole part of an abutted photosensitive body 203, is irradiated with corona discharge, so that the transfer paper hardly has the unevenness of a potential after being exposed, and the occurrence of the abnormal image having the difference in a density caused by the unevenness of the potential after being exposed is resolved. Thus, the generation of an abnormal image by a separating guide is prevented.
