20080285988 | Image forming apparatus and recording-medium feeding method - An image forming apparatus includes a storage unit configured to store a recording medium, an image forming unit configured to form an image on the recording medium, a paper feed unit configured to supply the recording medium from the storage unit, a conveying unit configured to convey the recording medium supplied by the paper feed unit to the image forming unit, and a control unit configured to control the paper feed unit and the conveying unit in conveying the recording medium. In accordance with a conveyance state in which the recording medium supplied from the storage unit by the paper feed unit is conveyed to the conveying unit, the control unit controls the conveying speed of the next recording medium supplied by the paper feed unit. | 11-20-2008 |
20110080605 | IMAGE FORMING APPARATUS - The image controller includes a FET which stops supply power from a low-voltage power supply to an ASIC (second processing unit) in a power-saving mode and starts the supply power in a normal mode, and a communication line for issuing a notification pertaining to transition from the power-saving mode to the normal mode between the image controller and a CPU(first processing part). The CPU controls the FET so as to start supply power to the ASIC when instructed by the image controller to transition from the power-saving mode to the normal mode through the communication line. | 04-07-2011 |
20140146347 | IMAGE FORMING APPARATUS - An image forming apparatus includes first through third control units, with the first for processing input image information and each of the second and third for controlling an operation of an image forming unit by communication with the first. In a first mode, in which power is supplied to the first through third control units, the first and third control units communicate via the second control unit. In a second mode, in which the first control unit does not communicate with the second control unit, the first and third control units communicate via a communication line without communicating via the second control unit. The power consumption of the second mode is lower than that of the first mode. In the second mode, the first and third control units can transmit information for transition from the second mode to the first mode to each other via the communication line. | 05-29-2014 |

20120112407 | RECORDING MATERIAL FEEDING APPARATUS AND IMAGE FORMING APPARATUS - In a sheet feeding cassette which lifts up and lifts down a bottom plate each time when a paper is fed, a recording material sensor detects that no recording materials exist when the bottom plate rises over a predetermined position. Accordingly, by measuring a period of time when it is detected that no recording materials exist during a sheet feeding operation, a stacking amount of the recording materials in a sheet feeding cassette can be detected. | 05-10-2012 |

20100089801 | PROCESS FOR PRODUCTION OF LOW-SPECIFIC-GRAVITY HOLLOW PARTICLES - To enable high-added-value low-specific-gravity hollow particles to be efficiently mass-produced by using, as a raw material, coal ash discharged when coal is combusted; enriching low-specific-gravity hollow particles contained in the raw material coal ash by classification to reduce the weight of the coal ash to be subjected to wet specific gravity separation; subjecting the raw material coal ash which have been reduced in weight to wet specific gravity separation to obtain low-specific-gravity components; and dehydrating and drying the low-specific-gravity components. | 04-15-2010 |
20130004389 | METHOD FOR SEPARATING ARSENIC MINERAL FROM COPPER-BEARING MATERIAL WITH HIGH ARSENIC GRADE - Disclosed herein is a method for separating an arsenic mineral from a copper-bearing material, including the steps of grinding a copper-bearing material containing arsenic, adding water to the copper-bearing material to prepare a slurry, and adding a flotation agent including a depressant, a frother, and a collector to the slurry and blowing air into the slurry for performing flotation to obtain a copper concentrate, wherein the depressant is a chelator. As the chelator, a polyethyleneamine or the like is used. Particularly, when triethylenetetramine is used as the chelator, the amount of triethylenetetramine to be added is preferably 1 to 10 equivalents relative to the amount of soluble copper generated by oxidation of the copper-bearing material, and the pH of the slurry is more preferably adjusted to 7 or more but 8 or less before the slurry is subjected to the flotation. | 01-03-2013 |
