A used toner conveyance device includes a lateral conveyance member for conveying used toner substantially in the horizontal direction, and a vertical conveyance member for upwardly conveying the used toner transferred from the lateral conveyance member. The vertical conveyance member transfers the used toner to either a collection space or a next conveyance path. The vertical conveyance member stops its operation when a prescribed delay time has elapsed after the lateral conveyance member stops conveyance operation.

A lubricant applying unit, included in a process cartridge provided in an image forming apparatus, includes a solid lubricant, a lubricant supporting unit to support the solid lubricant, a lubricant holder to accommodate the solid lubricant supported by the lubricant supporting unit, a pressing mechanism located between the lubricant supporting unit and the lubricant holder and designed to press the solid lubricant against a lubricant applying member, and a frictional resistance reducing member to reduce a frictional resistance produced at sliding contact portions between the lubricant supporting unit and internal surfaces of the lubricant holder.
摘要:
After a functional unit is pushed into the innermost position within the image forming apparatus main body, the unit is locked to the image forming apparatus main body by engaging a first locking member pivotally attached to a casing of the unit with a second locking member held by the casing to be movable vertically and by bringing the second locking member in pressure contact with a restricting member fixed to the image forming apparatus main body.
摘要:
A transferring apparatus is provided between a plurality of carrying apparatuses, each carrying apparatus comprising support means for supporting carried products Wf, guide means for controlling the moving direction of the support means, the guide means being provided along processing apparatuses for processing the carried products Wf, and moving means for moving the support means along the guide means. The transferring apparatus includes synchronization control means for synchronizing the moving means of the one carrying apparatus with the moving means of the other carrying apparatus; and at least one hand-over means for receiving the carried products Wf from the support means of the one carrying apparatus and handing over the carried products Wf to the support means of the other carrying apparatus.
摘要:
A fuel injection valve protecting apparatus for an LPG injection type engine operates when an excessive current passes through the fuel injection valve, or when an abnormality of the fuel injection valve occurs. An electrical fuse is inserted in a driving current supply line of the fuel injection valve. An electronic control apparatus has an abnormality diagnostic unit to detect any abnormality of the fuel injection valve by monitoring a check signal sent back from a fuel injection valve driving circuit, to thereby close a fuel shutoff valve and shut off the liquefied petroleum gas. Relief valves are connected in parallel between a petroleum gas supply line and an intake manifold so as to directly discharge any petroleum gas in the petroleum gas supply line into the intake manifold when the pressure difference between the petroleum gas supply line and the intake manifold reaches a set differential pressure.
摘要:
In an image forming device comprising an image forming part forming an image on a recording sheet, a sheet ejection part provided above the image forming part and stacking the recording sheet on which the image is formed by the image forming part, and an image reading part provided above the sheet ejection part and reading an image of an original document, the sheet ejection part is provided with a cover which is capable of being opened or closed to the sheet ejection part.
摘要:
An alkyl nitrite is produced with high efficiency by bringing a nitrogen monoxide gas into contact with an aqueous solution of an alkyl alcohol and nitric acid in a reactor 2, which aqueous solution may be a liquid fraction generated in an alkyl nitrite-production process in which an alkyl alcohol is reacted with nitrogen monoxide and oxygen in a reaction column 1.
摘要:
A cyclododecanone compound is continuously produced by an isomerization reaction of a corresponding epoxycyclododecane compound in the presence of a catalyst including lithium bromide and/or lithium iodide, the isomerization reaction being carried out by passing a reaction mixture containing the epoxycyclododecane compound and the catalyst through a continuous reaction apparatus including at least one tubular reactor preferably at a temperature of 100 to 350° C.
摘要:
A cyclododecanone compound is produced in a high reaction rate, with a high conversion of the starting compound, and with a high selectivity to and a high yield of the target compound by isomerizing an epoxycyclododecane compound in the presence of a catalyst comprising lithium bromide and/or lithium iodide, without using a solvent or in a non-polar solvent, in an inert gas atmosphere, while substantially no polymeric compounds having a high boiling temperature is produced.
