摘要:
This invention relates to a layered catalyst composition, a process for preparing the composition and processes for using the composition. The catalyst composition comprises an inner core such as alpha-alumina, and an outer layer bonded to the inner core composed of an outer refractory inorganic oxide such as gamma-alumina. The outer layer has uniformly dispersed thereon a platinum group metal such as platinum and a promoter metal such as tin. The composition also contains a modifier metal such as lithium. The catalyst composition shows improved durability and selectivity for dehydrogenating hydrocarbons.

An image forming apparatus includes an image bearer, a developing device to develop with developer a latent image formed on the image bearer, a developer container to contain developer, a temporary reservoir to temporarily store developer supplied from the developer container and having an outlet to discharge the temporarily stored developer to the developing device, a first conveyance device to transport developer from the developer container to the temporary reservoir, a second conveyance device to transport developer from the temporary reservoir to the developing device, a first developer amount detector to detect an amount of developer in the temporary reservoir, and a controller to control driving of the first conveyance device based on a detection result generated by the first developer amount detector and data relating to driving of the second conveyance device.
摘要:
A system with a container including a protrusion, and a receiver to receive the container. The receiver includes a slide block that is movable relative to a body of the receiver, the slide block including two surfaces, a first surface, initially contacted by the protrusion of the container during insertion of the container into the receiver, having a first slope to resist movement of the container towards the receiver, and a second surface, subsequently contacted by the protrusion of the container during the insertion of the container into the receiver, having a second slope to interact with the protrusion of the container to assist movement of the container towards the receiver. This construction provides the user with a changing insertion force to indicate proper mounting of the container.
摘要:
A toner container for use with an image forming apparatus which includes a horizontally mounted toner body mounted within the image forming apparatus, a toner outlet to discharge toner in a downward direction, and a shutter to open and close the toner outlet which moves along a first and second rail. The second rail is disposed downstream of the first rail in the insertion direction of the toner body and parallel to the length of the toner body. The longitudinal length of the first rail is smaller than the longitudinal length of the second rail.

A toner supply assembly includes a toner container mount and a toner container including a container body, a cap having a toner outlet, and a shutter for the toner outlet, to move horizontally. The cap includes a shutter guide rail, a contact portion, and a pressed rail provided on a lateral side. The shutter includes a shutter body to engage the shutter guide rail and a deformable portion deformable vertically and including a stopper to contact the contact portion of the cap for inhibiting the shutter from opening the toner outlet, and a stopper release projection pressed by a bottom projection on a bottom surface of the toner container mount in conjunction with installation of the toner container. A pressing member provided in a side portion of the toner container mount engages the pressed rail of the cap, inhibiting the cap from moving upward.
