摘要:
A method for detection of a precursor T cell or precursor B cell, a method for evaluation of the property of a hematopoietic precursor cell in a source for transplantation, and a kit for use in the evaluation are disclosed. A precursor T cell or precursor B cell can be detected by co-cultivating a stromal cell line with a monocyte. By using the detection method, a precursor T cell or precursor B cell can be quantified and can also evaluate the property of a hematopoietic precursor cell in a source for transplantation.

An insulating tube includes a underlying insulating film, a first sidewall insulating film disposed on the underlying insulating film, a second sidewall insulating film disposed on the underlying insulating film, opposite to the first sidewall insulating film so as to provide a cavity between the first and second sidewall insulating films having the same height as the first sidewall insulating film, and an upper insulating film provided over the first and second sidewall insulating films.
摘要:
An image forming apparatus and a method for cleaning a photoreceptor are realized that allow cleaning a surface of the photoreceptor to eliminate foreign substances adhering thereto, without using a special abrasive sheet. A recording sheet is fed and brought into contact with photoreceptors of all photoreceptor drums. The recording sheet is stopped by causing the vicinity of a rear end of the recording sheet to be sandwiched between a pair of registration rollers. Then, the photoreceptor drums are rotated. By this way, the cleaning is carried out to the photoreceptor.

A mountainous or valley-shaped curved part 13 is provided in a part of a footstep guide rail 3 for guiding a movement of footstep rollers 5 linked by a footstep chain 7, the part being positioned in the vicinity of a drive sprocket 9. Consequently, owing to meshing of the footstep rollers 5 with the drive sprocket 9, an unevenness in velocity of the footstep rollers 5 is absorbed by the curved part 13, so that a moving velocity of the footstep rollers 5 moving on the downstream of the curved part 13 is maintained constantly, suppressing vibrating of the footsteps 4.
摘要:
A sheet discharge device includes a housing for housing sheets discharged from an image forming apparatus. A matching reference device includes a plurality of reference members different in matching reference positions for arranging one end of the sheet in the housing. A matching device moves the sheet to the matching reference device to arrange the one end of the sheet.

In case of a developing density correction based on a test image (patch image) density, normally, the developing density is carried out in a short period of time by correction (γ correction) of a developing bias and a grid voltage (S11). When a correction amount of the γ correction exceeds an ordinary range, the γ correction (S11) and adjustment of toner concentration (magnetic permeability reference value) (S5) are carried out in combination. Furthermore, when the toner concentration is changed, the setting of a correction reference of the γ correction (γ correction TBL) and correction timing of the γ correction are accordingly changed (S6, S7). Therefore, in the developing density correction based on the test image density in the developing device using binary developer, it is possible to carry out the developing density correction, which is carried out in a short time, and whose correction width is wide, while maintaining the accuracy of a developing density adjustment.
