Title: Super wide angle lens
Inventor: OSHITA KOICHI
IPC: G02B13/04
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive super wide angle lens which is constituted of a small number of lenses and has a wide angle of view and where aberration other than distortion aberration is excellently compensated by arranging a 2nd lens having negative meniscus shape as an aberration compensating lens between a 1st lens being a divergent lens and a 3rd lens being an image- formation lens. SOLUTION: The thick negative meniscus lens whose convex surface is turned to an object side is inserted between the 1st lens L1 and the 3rd lens L3 as the 2nd lens L2, and constituted so that the dispersion of the 2nd lens L2 may be larger than the dispersion of the 1st lens L1 and that of the 3rd lens L3. Then, a condition, that is, an expression 0.5<ν2r3/(ν1r2)<0.8 is satisfied. In the expression, r2 shows the radius of curvature of the surface of the 1st lens L1 on an image side and r3 shows the radius of curvature of the surface of the 2nd lens L2 on the object side. ν1 shows the Abbe number of the 1st lens L1 and ν2 shows the Abbe number of the 2nd lens L2. Thus, the inexpensive super wide angel lens is realized by the constitution of only three lenses.

Title: Production of toner for development
Inventor: TSUBOTA NORIAKI
IPC: C08F2/44
Filed: 1986-11-29
Abstract: PURPOSE:To uniformize suspension polymerized particles to the grain size suitable for a toner by executing suspension polymn. in the presence of a radical polymn. initiator having 0.05/100cc solubility in water at 25 deg.C in the presence of a surfactant. CONSTITUTION:The mere use of the surfactant at the concn. lower than the critical micell concn. is not enough to avert incorporation of emulsion polymerized particles having small grain sizes at the time of suspension polymn. The use of the radical polymn. initiator having <=0.05g/100cc solubility in water at 25 deg.C is an essential requirement to entirely prevent the incorporation of the emulsion polymerized particles. Namely, the monomer dissolved in water exists to some extent in the suspension polymn. system. The polymn. of this monomer is started always by the radical polymn. initiator dissolved in the water and the polymn. initiation of the monomer dissolved in water is suppressed and the formation of the fine polymerized particles is suppressed if the solubility in water of the radical polymn. initiator is confined to the above-mentioned standard value or below.

Title: File protecting method
Inventor: NAKAMURA KEIGO
IPC: G06F12/00
Filed: 1993-11-15
Abstract: PURPOSE:To improve the operability of a protecting method for secret files which have passwords individually by solving such an inconveniences in the handling of a conventional method as inputting a password each time a file is accessed. CONSTITUTION:Each file is given a password which has priority (rank) and then a user which has a password of lower priority is disabled to access other files (S6), thereby improving the reliability of secrecy protection. A user, when having a password of high priority, can access files without inputting passwords repeatedly. Specially, a supervisor of a computer can access files similarly to a file which does not have a password by having a password of top priority. Further, the password is inputted only at the start of processing operation (S1) and then the trouble of repeatedly inputting the password each time a file is accessed is eliminated unlike the conventional method, thereby improving the handling.

IPC: A46B7/10
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To eliminate clogging with toner, to prevent stress from being exerted on the toner, and to realize a driving where rotational torque is small, by constituting the surface of a supply roller of fiber-flocked body consisting of conductive short fibers. SOLUTION: The supply roller 42 is constituted of a metallic shaft 42a and the fiber flocked body 42b having many conductive short fibers and stuck to the peripheral body of the shaft 42a, and the shaft 42a obtains motive power from a driving source outside the developing unit 4 and rotates in the direction of an arrow C. By the rotation of the roller 42 in the direction of the arrow C, the toner adhering between the fibers of the fiber flocked body 42b is transferred to a developing roller 43 side and shifted to the roller 43 because of potential difference between the rollers 42 and 43 at an abutting part between them, then adheres to the surface of the roller 43. In this process, the toner is retained between the fibers because the fiber flocked body consisting of the conductive short fibers is stuck to the surface of the roller 42.  However, the holding power thereof is not so strong as that of the foam part of a foamed body, so that faulty supply due to the clogging is not caused.
