摘要:
A liquid type development device for developing an electrostatic latent image formed on image-holding equipment by using liquid developer made of a highly insulating solvent and toner particles dispersed in the solvent has a liquid developer tank detachably situated in a cartridge; and at least one supplementary liquid tank containing supplementary liquid to be added to liquid developer contained in the liquid developer tank so as to keep the concentration of nonvolatile components in the liquid developer constant. Further, when the used development cartridge is recovered, and another new development cartridge is bought, a discount price privilege for the newly bought development cartridge is given to a user who has turned in the used cartridge.

A magnetic head slider having a magnetic head for reading/writing information from/into a magnetic disk and a slider on which the magnetic head is mounted. The slider has three surface portions with levels which are different from each other on a surface facing to the magnetic disk including a first surface portion forming a pad surface, a second surface portion having a level which is lower than a level of the first surface portion and a third surface portion having a level which is lower than that of the second surface portion. The second surface portion is provided at a side opposite to a side on which the magnetic head is mounted and the third surface portion is provided at the side on which the magnetic head is mounted. A projection is provided on the second surface portion.

In a recording/reproducing apparatus having a large number of probes, being still usable continuously when several pieces of the probes are in trouble, wherein a plural number of probes are so disposed that they can make recording and/or reproducing onto the same recording area, which is in charge of the probes, respectively, and when defect, such as, a trouble is generated within a first probe, that defect is detected, automatically, so as to exchanged into a spare probe built within the frame, thereby compensating the defect.

A magnetic head slider includes a magnetic head for recording/reproducing information from/into a magnetic disk and a slider on which the magnetic head is mounted. The slider has a first positive pressure generating portion provided at an air-inflow side and a positive pressure generating portion surface provided at an air-outflow side. Projections are provided at the air-inflow side respect to the first positive pressure generating portion on a surface which faces the magnetic disk upon read/write operation of the magnetic head slider.

For providing a recording/reproducing apparatus, for recording/reproducing information through conduction of electricity upon contact of a probe, having large recording density and a large transfer speed, but less in deterioration of a probe chips thereof, and being long in the lifetime thereof, within the recording/reproducing apparatus, a multi-chip is formed, disposing probe chips in large numbers thereof at a tip of a cantilever, while the cantilever is of a double-sided beam type, and the multi-chip is disposed at a center of the beam, wherein recording/reproducing portions of the multi-chip are disposed to correspond to recording dots one by one, and the multi-chip forming surface is moved up and down in parallel with the surface of a recording medium, due to suction force, so as to bring it to be in contact with the recording dots, and electricity is conducted after the contact thereof, thereby conducting the recording, in the structure; wherein, since a large amount of data can be read/written at one time, therefore it is possible to improve data transfer speed. Also, with conducting the R/W by means of the multi-chip, comparing to the single chip, it is possible to reduce the traveling distance of the multi-chip, thereby to reduce the abrasion. Also, since the tip portion of the said chip has the curvature radius, being large, such as, equal to 50 nm or greater than that, and since it moves in parallel with the surface of the recording medium, it can be in contact with the surface under the condition of, not the point contact, but near to the plane contact, therefore, the abrasion can be further reduced, effectively.

摘要:
An image processing apparatus for a laser printer, wherein a halftone control through laser pulse modulation (PWM) is used in combination with distributed clustered-dot halftone processing which distributes a tone level over four clustered-dots, and the value represented by higher bits of a threshold are used to switch a PWM pulse pattern in a highlight area to a discontinuous pattern, thereby implementing the high density halftone processing, which provides a high highlight tone density and stability, only with a small scale memory and circuit.
