Title: Pulse bias developing system for magnetic toner
Inventor: ENOKI SHIGEKAZU
IPC: G03G15/08
Filed: 1978-10-20
Abstract: PURPOSE: To prevent excess development by developing a latent image in a pulse bias applied region using the toner which has passed by a grounded first electrode and a DC and AC voltage applied second electrode.  
     CONSTITUTION: First grounded electrode 6 and second electrode 9 connected to an injection power source consisting of DC source 7 and further AC source 8 are installed to inject charge into toner 4 fed from toner case 5.

Title: Laying method for block mat
Inventor: WATARI FUMIHIKO
IPC: E02D17/20
Filed: 1988-05-26
Abstract: PURPOSE:To form a wide, stable laying surface by joining an excess end of the existing block mat with a block mat superposed on that together with a bonding agent or the like for unification. CONSTITUTION:A side edge of a block mat 1 being adjacently laid doen is laid down in superposition on an excess end 4 installed in a one-side edge of the existing block mat 1 so far laied down on the ground, and the interval is joined tight with a bonding agent or the like. These block mats 1 are joined to each other in superposition at the excess end 4 in the longitudinal direction and/or the cross correction, thereby forming such a wide laying surface that plural numbers of block mats 1 are unified. With this constitution, they act as one-piece block mat, so that excellent laying stability can be brought into full play owing to the heavy weight and the wider grounding surface in combination.

Title: Vertical motion mechanism for delivery roller
Inventor: TANAKA HIRONORI
IPC: B65H3/06
Filed: 1991-05-31
Abstract: PURPOSE:To vertically drive an delivery roller with a drive shaft normally or reversely rotated by shaft-supporting drive and delivery rollers with a rotary angle, dividing the drive shaft into main and sub-drive shafts to be linked with a spring, and arranging an intermediate gear between both the roller gears to give a rotation load. CONSTITUTION:Drive and delivery rollers 4 and 2 are shaft-supported with a rotation angle 1, and gears 8 and 9 are fitted to both the shafts 3b and 2a of the rollers 4 and 2 and also engaged with an intermediate gear 10. The drive shaft is composed of a main shaft 3A linked to a drive source 11 and a divided sub-shaft 3B, and both the shafts 3A and 3B are connected with a coil spring 13 via sleeves 14 and 15. When the drive shaft 3b is normally rotated and sheet feeding with the drive roller 4 is finished, the drive roller 4 is stopped, and the delivery roller 2 is stopped at an ascended position due to the rotation load of the intermediate gear 10. Then the fixed-quantity reversal of the drive source 11 causes loosening the coil spring 13 to release the link with the sub- drive shaft 3B, and the rotation moment of the intermediate gear 10 is vanished to descend the delivery roller 2.

Filed: 1994-05-06
Abstract: PURPOSE:To eliminate lithium ion shortage in a negative electrode during charge and prevent deterioration in capacity by adding the mixture of a solid lithium ion conductor and a carbon material serving as an active material in the negative electrode. CONSTITUTION:Li3N, acetylene black, a PVDF binder, and a solvent are mixed to heat-treated meso-carbon microbeads to form a pasty material, the pasty material is applied to a negative current collector, dried, then press-molded to form a negative electrode 1. Graphite, acetylene black, PVDF, and a solvent are mixed to spinel lithium-manganese oxide to form a pasty mixture, then the pasty mixture is applied to a positive current collector, dried, then press- molded to form a positive electrode 2. A porous polypropylene separator is interposed between the positive electrode 2 and the negative electrode 1, then they are wound in a roll to form a battery element. The battery element is accommodated into a battery can 3, and an electrolyte is poured to form a battery. Since the battery contains Li3N as the solid lithium ion conductor in the negative electrode, capacity drop is decreased, and 94% of the initial capacity is maintained in 200th cycles.
