An immobilized phase is a stationary phase that is immobilized on the support particles, or on the inner wall of the column tubing. Target proteins are captured on the adsorbent, while particulates and contaminants pass through.

After the feeding torque provided by the drive motor overcomes the resistant torque provided by the adjusting device, the roller set starts feeding paper with the cooperation of the first, second and third gears. The paper feed apparatus comprises a plurality of projections capable of engaging with an end of the paper and of projecting from the inclined surface; and a plurality of resilient arm portions for holding the respective projections at respective positions allowing the respective projections to project from the inclined surface.

In conclusion, according to the preferred embodiment of the present invention, the paper separation mechanism employs the resistant torque provided by the adjusting device to reduce the feeding torque provided by the roller set, so that when the first roller of the roller set is driven by the drive motor, the roller set rotates downwardly to enable the second roller to contact the paper sheet.

The design of the conjugate cams was analyzed in this paper, and the calculation process of conjugate cams profile data to meet the pressure angle and the curvature radius was introduced in detail.

That is, the amount of bending of the arm portion may be increased, and may be controlled in accordance with a small change of the load imposed by the paper.

The character and image materials include documents, magazines, books and pictures. The paper is placed in a container with a shallow layer of solvent and sealed. After the feeding torque provided by the drive motor overcomes the resistant torque provided by the adjusting device, the roller set starts feeding paper with the cooperation of the first, second and third gears.

The paper separation mechanism according to claims 2 and 3 wherein said first gear is disposed on a side of said first roller, said third gear is disposed on a side of said second roller, and said second gear is meshed between said first gear and said third gear.

In addition, the adjusting device 23 is disposed on a side of the second gear and provides a resistant torque. The solute refers to the sample components in partition chromatography.

Displacement chromatography[ edit ] The basic principle of displacement chromatography is: The driving motor 50 is used for driving the transmission gear assembly The one-way clutch is capable of rotating in a one-way direction, when the one-way clutch rotates, the separation shaft is capable of being driven by the one-way clutch module to swing downward to make the separation roller break away from the pickup roller.

The spring is disposed to the bottom of the swing arm and being capable of elastically pushing against the swing arm.

Design and Research of Cam for Paper-Separation Mechanism

Certainly, the position and the amount of the gear set 22 are not limited to the disclosed embodiment, and the amount of the adjusting device 23 can be increased in response to various requirements, and the adjusting device 23 is not limited to be only disposed on the second gear Preferably, the paper separation mechanism further comprising a protruding shaft disposed on a sidewall of the roller set for receiving the adjusting device.

The roller set 21 comprises a first roller and a second rollerand the first roller 21 is driven by the drive motor not shown through the transmission shaft Preferably, the first gear is disposed on a side of the first roller, the third gear is disposed on a side of the second roller, and the second gear is meshed between the first gear and the third gear.

The separation mechanism depends upon The paper separation mechanism according to claim 1 further comprising a protruding shaft disposed on a sidewall of said roller set for receiving said adjusting device.

The expanded bed layer displays a state of piston flow. Paper Chromatography Separation Mechanisms Science of The paper separation mechanism according to claim 15 wherein said resilient component is a spring. When the thrust provided by the drive motor overcomes the resistant torque provided by the adjusting device 23, the first gear has sufficient torque to drive rotations of the second gear and the third gear meshed with the second gearso the second roller can roll in the same direction as that of the first rollerand thus, the uppermost paper sheet can be easily delivered into the paper feeding mechanism.

The paper separation mechanism according to claim 1 wherein said gear set comprises a first gear, a second gear, and a third gear.

The paper separation mechanism according to claims 2 and 3 wherein said first gear is disposed on a side of said first roller, said third gear is disposed on a side of said second roller, and said second gear is meshed between said first gear and said third gear.

The transmission gear 41 is connected with and drives the feeding roller Share with Your Friends. After the feeding demand disappears, the drive motor provides a reverse driving torque, so that the whole roller set 21 will rotate upwardly and the second roller will be lifted and apart from the surface of the paper sheet to stop the paper delivery.

As shown in FIG. Thus, feeding of a plurality of sheets of the paper simultaneously is prevented and stable paper feed can be achieved.

Both the single-function peripheral and the multi-function peripheral have a paper feeding mechanism and a paper separation mechanism, so as to feed paper sheets such as the originals placed on the tray into the image processing unit of the peripheral to be further copied, faxed, printed or scanned.

According to an aspect of the present invention, there is provided a paper separation mechanism. A protruding shaft 25 is disposed on a sidewall of the roller set 23, and the resilient component such as a springthe friction disc and the friction plate are sequentially sleeved on the protruding shaft 25, and then, the second gear is fixed at the end of the protruding shaft Certainly, the position and the amount of the gear set 22 are not limited to the disclosed embodiment, and the amount of the adjusting device 23 can be increased in response to various requirements, and the adjusting device 23 is not limited to be only disposed on the second gear In some embodiments, the paper separation mechanism is applied to a copy machine, a fax machine, a printer, a scanner or a multi-function peripheral.

Techniques by separation mechanism[ edit ] Ion exchange chromatography[ edit ] Further information:. Paper chromatography uses a cellulose paper as the stationary phase, and the mechanism of separation is based on solid-liquid adsorption.

TLC also uses solid-liquid adsorption mechanisms. The molecules are separated on the stationary phase, depending on their solubility in the mobile phase.
