  • Patent number: 8377303
    Abstract: A channel groove pattern 38 allowing the passage of a permeated liquid having passed through a filtration membrane 37 is provided on one filtration plate surface of a filtration plate 36, and a permeated liquid outlet nozzle 39 is provided on the filtration plate 36. The channel groove pattern 38 includes multiple channel grooves 38a, and a header groove 44 for averaging suction pressures is formed on the filtration plate 36. An area where the channel groove pattern 38 is formed is divided into upper and lower water collection areas 46 and 47 by the header groove 44. The permeated liquid outlet nozzle 39 and the header groove 44 communicate with each other through the channel grooves 38a of the water collection area 46, and the channel cross-sectional area of the header groove 44 is larger than that of the channel groove 38a.

  • Patent number: 8081896
    Abstract: An image forming apparatus includes an image forming mechanism for forming an image, at least one developer container replaceably provided in the image forming apparatus for containing developer, a housing for housing the image forming mechanism and the at least one developer container, and an operation device provided on the housing. The housing includes at least one openable portion opened for replacement of the at least one developer container. The operation device includes an instruction display part for indicating a message prompting opening of the at least one openable portion, and at least one developer-end display part for indicating depletion or near-depletion of the developer contained in any one of the at least one developer container. The at least one developer-end display part and the instruction display part are placed adjacent to each other and are viewable from a front side of the image forming apparatus.
