Title: Developing device
Inventor: TAKAHASHI MICHIO
IPC: G03G15/09
Filed: 1988-09-22
Abstract: PURPOSE:To eliminate a void arising in a peripheral part of a solid image by installing an electrode plate, which attracts toner included in developer to the surface of the developer, in the upstream part of a developing area in the developer feeding direction. CONSTITUTION:The developing area 25 is formed in the part where a developing roller 18 faces a photosensitive drum 24. Development is performed in the developing area 25 by bringing the bristle edge of a magnetic brush 20 in contact with the surface of the photosensitive drum 24. In addition, the electrode plate 20 which attracts toner included in the developer forming the magnetic brush 20 to the surface of the magnetic brush 20 is installed in the upstream part of the developing area 25 in a magnetic brush feeding direction. A bias voltage of polarity opposite from the electrified polarity of the toner is applied by a power supply circuit 31 to the electrode plate 20. Therefore, a void occurring in the peripheral part of the solid image is eliminated.

Title: Aerial power-transmission line
Inventor: OZAKI MASANORI
IPC: H01B5/02
Filed: 1989-09-13
Abstract: PURPOSE:To prevent any damage to a conductive ceramics layer and also to control the generation of pinhole by forming a specified interlayer on the surface of a twisted wire, and forming the ceramics layer on the surface of the interlayer. CONSTITUTION:On surface of a twisted wire 1 is formed an interlayer 2 having such gradient composition that is composed of A and Bx(A: transition metal IV/V groups. B: carbon, nitrogen and boron), and a twisted-wire side has x=0, an outermost-layer side has carbon, nitrogen has x=1 and boron has x=2. Then, a conductive ceramics layer 3 made of the transition metal IV/V groups is formed on the surface of the interlayer. The transition metal IV/V groups at this point have excellent conductivity so that the lightning surge resistance of an overhead power-transmission cable may be improved. Furthermore, metallic elements contact each other at the interface between the twisted wire 1 and the interlayer 2 while ceramics of same kind of composition contact each other at the interface between the interlayer 2 and the conductive ceramics layer 3, so that their interfacial affinities become excellent for improving each interfacial adhesion to ease any stress resulting from differential thermal expansion. This can prevent any damage to the conductive ceramics layer 3 while laminating these layers can also prevent the generation of a pinhole.

Title: Pipe joining device
Inventor: TOSHIMA TOSHIO
IPC: F16L19/03
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To efficiently and accurately mount a press ring with no danger accompanied by pressing a seal member in place between a socket and a spigot by the press ring, and concurrently inserting the screw part of a bolt into the bolt hole of the press ring. SOLUTION: A second plate 23 on which a press ring setter 42 is mounted, is drawn to a first plate 21 with a cylinder device 22 actuated. The drawing motion as mentioned above causes the press ring 10 together with the press ring setter 42 to be approached to the flange 7 of a socket 2. At this time, a seal member 9 is pressed by the press ring 10 so as to be pressed in a space between the pressure contact surface 5 of a seal member and the outer circumferential surface of a spigot 4. Besides, the screw part of a T-head bolt 15 is inserted into the bolt hole 11 of the press ring 10, and is furthermore projected out of the press ring 10. Thus as mentioned above, when the screw part of the T-head bolt is inserted into the bolt hole 11, a nut is coaxially located over the screw part of the T-head bolt 15.  By this constitution, the nut held by a socket 70 is thereby threadedly engaged with the screw part of the T-head bolt 15.

Title: Sintering raw material charging device using rotor
Inventor: SASA YUTAKA
IPC: C22B1/20
Filed: 1993-09-24
Abstract: PURPOSE:To improve breathability of a raw material filled layer during sintering time by reinforcing particle segregation and to manufacture sintered ores with high productivity. CONSTITUTION:When filling up a sintering raw material 2 cut out from a hopper on a pallet 6 of a sintering machine by way of a slope shoot 4, a stripper 10 is incorporated to the lower side of the slope shoot 4 while a rotor 5 is installed.

Filed: 1993-09-24
Abstract: PURPOSE:To easily remove a container lid without leaving metal member constituting a tearing member at the time of use by providing a closing member comprising a metal plate having applied film layers on a surface and a rear face with an attaching wall along an outer periphery, adhering a pulling member to a surface of the closing member and adhering a rear of the attaching wall to the tearing member. CONSTITUTION:A metal plate 422 is a disk-like laminate plate having applied film layers 423, 424 made of a synthetic resin coated on a surface and a rear face. A closing member 42 including an attaching wall 426 folded and formed from an outer peripheral rim of an upper wall is provided on an outer periphery of the disk-like laminate plate. A pulling member 44 is adhered to a surface of the closing member 42, and a tearing part 28 is adhered to a rear face 428 of the attaching wall 426. Thus since an end face of the metal plate 422 constituting the closing member 42 cannot be in contact with contained liquid, the entire tearing member 28 can be removed without leaving a metal member.
