摘要:
A print data generating apparatus to generate print data, which is to be used in a printing apparatus to form an image in a plurality of colorants, based on originally inputted image data representing the image, is provided. The print data generating apparatus includes a black enabled image data converter unit to convert the inputted image data into black enabled image data, which indicates scale values of a plurality of colors including a black color to be used in the image, a white scale value calculator unit to obtain scale values of a white color to be used in the image to be formed. The white scale value calculator unit calculates the scale values of the white color by inverting the scale values of the black color obtained in the conversion by the black enabled image data converter unit.

An image formation control system including an input system that is adapted to input instruction signals concerning a vividness enhancement target color of image signals from a user, and a vividness enhancement processing system that is adapted to apply a vividness enhancement process by converting at least one first area of a color space concerning the image signals to a single vividness enhancement target color corresponding to each first area according to the instruction signals from the user input through the input system, and by determining a second area which is the remaining area of the color space wherein the vividness enhancement process is not applied is provided. The image signals processed with the vividness enhancement process are converted to output data for a printer.

An apparatus and method for cleaning a plurality of drums in an image forming apparatus includes applying a first bias to each of a plurality of disturbing members, each disturbing member associated with a corresponding drum of a plurality of drums. While performing an image forming operation wherein at least one of the plurality of drums is not use, the bias is changed of a disturbing member corresponding to at least one of the plurality of drums not used in performing the image forming operation from the first bias to a second bias different from the first bias.

The objective of the present invention is to provide a type of probe assembly with a long lifetime and low cost, as well as a type of probe card using same. Probe assembly 100 attached on the probe card has probe holder 200 that holds plural probes Q at prescribed positions and leaf spring mechanism 300 with probe holder 200 attached on it. Said leaf spring mechanism 300 has leaf spring cover 360 connected to probe card base plate 410 and leaf spring 330, as well as pin row base plate 310 with probe holder 200 attached on it. When the bump electrodes are contacted, pin row base plate 310 can move towards leaf spring cover 360 via leaf spring 330.

An anisotropic conductive sheet interposed between a circuit board such as a substrate and various circuit parts to render them conductive and its manufacturing method. The anisotropic conductive sheet has a fine pitch required by the recent highly integrated circuit boards and electronic parts. In the anisotropic conductive sheet in which conductive members are scattered in a nonconductive matrix, the conductive members (e.g., 24) penetrate through the sheet (10) in the direction of thickness and conductive auxiliary layers (e.g., 25) are in contact with the conductive members (e.g., 24).

The invention provides a film driving apparatus in which no adverse effect is caused by a change in the circumferential length of a film even if there arises the change in circumferential length of the film due to environmental fluctuation. In the film driving apparatus, an endless film 1 supported by a driving roller 2, a film support roller 4 and a skew correction roller 3 is rotated in a predetermined direction by the rotation of a driving roller 2. The skew correction roller 3 has a structure in which one end thereof is movable with the other end as a fulcrum. The movement trajectory of the movable end portion of the skew correction roller 3 is an elliptic trajectory not causing any change in the circumferential length of the film 1.
