Title: Conveyer device
Inventor: NANUN DAISUKE
IPC: B65G17/34
Filed: 1985-06-05
Abstract: PURPOSE:To enhance the working efficiency of a conveyer device, by securing a shield member in a gap between support members attached between a pair of chains, and by positioning pins both ends of the shield member on the axes of pins of the chains so that it is possible to convey even glanular materials. CONSTITUTION:Each of support members 10, 10 having a rectangular shape laterally extending, is secured at both sides of its lower section, with L-shape attaching sections 12 extending downward from a part of chains 8, 8. Each support member 10 carries on its upper surface a cargo. Each coupling section 16 of a shield member 11 made of somewhat flexible materials is fitted in each associated holding section 14 on each support member 10, which is opened upward. Further, the coupling sections 16 are positioned on the lines which are the extension of the center axis of pins 17, 17 in the chains 8, 8. Therefore, since the distance between coupling sections 16, 16 is unaltered even though a conveyer body 9 becomes arcuate, no tension and compression are exerted to the flat section of each member 11, and therefore, the gap between each adjacent support member 10 is blocked, so that no glanular materials, etc. spill out.

Title: Image forming device
Inventor: MOCHIDA YOSHINORI
IPC: G03G15/16
Filed: 1989-05-16
Abstract: PURPOSE:To prevent the offset to an image holding body of a toner image caused by pressure of a backup member, and the irregularities in a transfer image caused by ironing by constituting the backup member being a transfer auxiliary means so that press-contacting is started to a tapered part at the time of passing through a transfer position. CONSTITUTION:A transfer electrifier 24 is outputted in accordance with the moving timing of transfer paper and a movement of a connecting member 5c of a transfer drum, and a backup member 61 is pressed against a suction sheet 53. In this case, the member 5c moves to a transfer position by gripping the tip of the transfer paper by a gripper 51. Subsequently, when a tapered part E provided on the tip side of the transfer paper comes to the transfer position, the member 61 is moved, and moved to a prescribed position, while bumping the member 61 against the tapered part E. In this case, the tip of the member 61 hits against the tapered part E of the member 5c first, but it is extremely near the sheet 54 in the radial direction since the tapered part E is inclined, therefore, buckling of the member 61 is not generated. Also, an impact given to the member 53 is also small. In such a way, the offset and the irregularities in a transfer image can be prevented.

Title: Regenerating method by desorption under heating
Inventor: KOMURO TAKEO
IPC: B01D53/34
Filed: 1981-08-05
Abstract: PURPOSE:To efficiently perform a regeneration by desorption under heating and to reduce a supplying quantity of inert gas, by providing a narrowed part to a boundary between a heating zone and a cooling zone in a regenerating tower for desorption by heating, as well as providing a suction blower for sucking inert gas and a gas after desorption. CONSTITUTION:Desulfurizing agent 1, after adsorbing oxides of sulfur, is supplied to a hopper 2, flowing down in a heating zone 5 through a valve 4 and is regenerated by desorption under heating. The agent 1 is further flowed down in a cooling zone 6 to be cooled and is taken out by the flow controlling of a valve 7 located at the lower part of a tower. Hereupon inert gas 10 is supplied from the lower part of a narrowed part 15 provided to a boundary between a heating part and a cooling part, but the inert gas 10 is prevented from diffusing into the cooling zone 6 because its flow rate increases when it flows upward  through a partitioning part of the agent 1 of the part 15. Further, as a suction  blower 12 sucks a gas after desorbing and the inert gas, both of the same  quantity, and always keeps the internal pressure of the tower close to the  atomospheric pressure, the regeneration by desorption under heating is smoothly performed.
