Title: Electrophotographic toner, toner cartridge and developing system
Inventor: OGINO TAKESHI
IPC: G03G9/08
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic toner not causing toner filming over a long period of time even in high-speed development and capable of satisfactory image printing by specifying compressive breaking stress and the amt. of fine toner particles. SOLUTION: An electrophotographic toner having >=0.5kgf/m<2> compressive breaking stress and contg. <=2% fine toner particles of <=5μm particle, diameter is used. Since fine toner particles have been removed, toner filming can be suppressed. In order to suppress the formation of fine toner particles in a developing unit as well as to remove fine toner particles in a toner, the hardness of the toner is increased and the toner is made less liable to break even at the time of holding between carrier particles. The toner used is produced by the conventional known method.

IPC: G02B21/06
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent interference fringe on an observed image even in the case of using a laser as a light source by making an image-forming optical system substantially telecentric on an image side and further arranging it so that an imaging device may be inclined to an image surface. SOLUTION: A microscope is constituted to perform observation by forming the image of an illuminated object to be inspected 4 by an objective lens 3 and a 2nd objective lens 5 on the image pickup surface 8 of a TV camera put to be aligned with the image surface 6 and displaying an observed image on a TV monitor. The image-forming optical system is substantially telecentric on the image side and further is arranged so that the imaging device may be inclined to the image surface.  By making an image-forming system telecentric on the image side, the inclination of a main light beam becomes the same between luminous flux at a center part and that at a peripheral part, so that reflected light of all the luminous flux is relieved to the outside of the image- forming system by inclining an image pickup surface, whereby the interference fringe is prevented from being caused on the observed image.

Title: Amplifying circuit for charge transfer device
Inventor: MIYAMOTO YOSHIHIRO
IPC: H03F3/70
Filed: 1980-03-27
Abstract: PURPOSE: To obtain an amplifying circuit for CTD which can easily be integrated with CTD and has an adequate DC component suppressing function, by utilizing the triode operation range of amplifying MOST.  
     CONSTITUTION: Once signal charge enters output diode 8 of CTDb, resetting MOST5 turns off. As the junction capacitor of output diode 8 is charged, gate G of amplifying MOST1 drops in potential to generate an input signal to amplifying circuit (a). When the input voltage is expressed by the ordinate and the output voltage by the abscissa, the gradient showing the degree of amplification is shown by curve K. In region (c) of this curve K, MOST1 enters the triode operation region and while the gate mutual conductance does not increase much, the degree of amplification decreases suddenly. For this porpose, the amplitude of a signal voltage energizing the gate terminal of MOST1 is set a little bit beyond region (c), so that a DC component based upon the background light of the input signal can greatly by suppressed.
