  • Patent number: 5774774
    Abstract: A method for printing on a metal item includes the step of successively forming a plurality of electrostatic latent images based on print information color-separated into yellow, magenta, cyan and black, on a photosensitive drum. The electrostatic latent images are successively developed by toners of different colors corresponding to the color-separated print information. A multicolor toner image is formed on an intermediate transfer medium having a cushion layer thereon by successively repeating a process in which the toner images are transferred to the intermediate transfer medium in layers. The multicolor toner image is transferred onto a surface of a metal item. Thereafter, the multicolor toner image is fixed on the surface of the metal item.

  • Patent number: 5774205
    Abstract: An exposure apparatus for and a method of producing devices, in which an original pattern such as a reticle is projected onto an object such as a wafer to be exposed, through a projection optical system. The projection optical system includes at least one optical element, optical characteristics thereof having been tested using a measuring beam having a first wavelength region. An exposure light source emits a light beam having a second wavelength region, selected independently from the first wavelength region, to irradiate the original pattern with the beam from the exposure light source, so that an image of the pattern is projected onto the object through the projection optical system, thereby exposing the object to produce the device.

  • Patent number: 5767948
    Abstract: A lithographic device includes a machine frame which supports a substrate holder, a focusing system and a mask holder in a vertical direction. The substrate holder is displaceable parallel to a horizontal X-direction and a horizontal Y-direction perpendicular to the X-direction by a first positioning device, and the mask holder is displaceable parallel to the X-direction by a second positioning device. The substrate holder and the mask holder are displaced synchronously parallel to the X-direction during exposure of a semiconductor substrate. The second positioning device is capable of positioning the mask holder also parallel to the Y-direction and of rotating it about a vertical axis of rotation. Therefore, a displacement of the mask holder has a parallelism to the X-direction which is determined by a positioning accuracy of the second positioning device and which is not adversely affected by a deviation from parallelism and straightness of a guide of the second positioning device.

  • Patent number: 5758252
    Abstract: An image forming apparatus includes an image carrying body on which a toner image is created. A sheet carrying/transporting rotational body adsorbs a recording sheet to which the toner image on the image carrying body is transferred, and transports the sheet. The recording sheet is detached after transfer from the sheet carrying/transporting rotating body, and an assisting device thrusts against the non-image area of the recording sheet to limit its detachment from the sheet carrying/transporting rotating body. The image forming device can prevent transportation failure and image smudging that is otherwise generated when a thick sheet provided with a curl before it is adsorbed to a sheet carrying/transporting rotational body is detached in the curved state from the rotational body and transported to a fusing means.
