摘要:
An image forming apparatus may includes a central processing device, a first switching regulator and a second switching regulator. The central processing device may perform information processing associated with image formation. The first switching regulator may receive an input of a first voltage and output a second voltage which is lower than the first voltage. The second switching regulator may receive an input of the second voltage and output a third voltage which is lower than the second voltage. The third voltage may be input to the central processing device. A first switching frequency which is a switching frequency of the first switching regulator may be lower than a second switching firequency which is a switching frequency of the second switching regulator.

An interlocking device for a camera release of an interlock between a film advance lever and a shutter release button and a power switch when the film advance lever is in a housed position. This device comprises a rotating cam interlocking the film advance lever, and an operating lever to lock the shutter release button and at the same time to open the power switch in a first position, and to unlock the shutter release button and at the same time to close the power switch in a second position. This device also comprises an outside operating lever which can rotate the first operating lever to the second position selectively even when the advance lever is in the first position to release the interlock.

A liquid ejecting device has a liquid ejecting head to eject ink to a sheet-like object, a carriage mounting the liquid ejecting head, a conveying device which conveys the sheet-like object with holding the sheet-like object to have a corrugated shape having a corrugated cross-section in the scanning direction, a detecting unit which detects an end portion of the sheet-like object in the scanning direction, and a processor. The processor is configured to execute instructions to provide an ejection timing determining unit configured to determine an ejection timing at which the liquid is ejected from the liquid ejecting head in accordance with positional information representing the end portion detected by the detecting unit and reference information, and an ejection control unit configured to control the liquid ejecting head and the carriage to eject the liquid from the liquid ejecting head at the timing determined by the ejection timing determining unit.
摘要:
A method of removing silicon from a waste hydrochloric acid pickling solution is disclosed which comprises stirring the waste solution long enough to form a sludge having a particle size such that the sludge can be separated by a conventional means such as filtration through a filter of at least 0.1 .mu.m in pore diameter, centrifugation or sedimentation. The stirring period can be greatly reduced by adding to the waste pickling solution sludge recovered from an aged waste hydrochloric acid pickling solution or a carbonaceous material such as carbon black having hydrophilic groups on the surface. The sludge is also useful as a filter medium in filtration of the waste pickling solution to remove silicon. The present method can decrease the silicon content to 0.01% or less in terms of converted SiO.sub.2 /Fe.sub.2 O.sub.3 weight ratio.

摘要:
An image forming apparatus may be configured to enter a first state where electric power is supplied from a power supply and a second state where no electric power is supplied from the power supply. A capacitor may be connected to the power supply, and may be charged by the power supply in the first state. A controller may be connected to the capacitor, and may operate with electric power supplied from the capacitor in the second state. The controller may operate with electric power supplied from the power supply in the first state. The controller may cause the image forming apparatus to enter the first state upon detecting that the image forming apparatus is in a predetermined state. The controller may acquire the related information and may cause the image forming apparatus to enter the second state.
摘要:
An inkjet printer is provided that includes a control device configured to determine an ink discharge moment when an inkjet head discharges an ink droplet from nozzles while moving within at least one of a acceleration range to accelerate the inkjet head and a deceleration range to decelerate the inkjet head, based on a distance between an ink discharge surface of the inkjet head and a recording sheet held in a predetermined wave shape and an amount of change in a moving velocity of the inkjet head.
