  • Patent number: 8274540
    Abstract: An image forming apparatus includes a photoconductive body on which an electrostatic latent image is formed, an exposure unit which exposes the photoconductive body, a first pressing member which presses the exposure unit toward the photoconductive body, a first positioning member which makes a contact with the exposure unit, a second positioning member which is arranged at a side nearer to the photoconductive body than the first positioning member in an optical axial direction of light, and a second pressing member which presses the exposure unit toward the second positioning member. A point of action at which the first pressing member presses the exposure unit is positioned at a side nearer to the photoconductive body, than the first positioning member in the optical axial direction. It is possible to suppress a degradation of an image quality by suppressing an effect of vibrations with respect to the exposure unit.

  • Patent number: 7825946
    Abstract: An image forming apparatus includes: a photosensitive body which is moved in a movement direction; an exposing unit which exposes the photosensitive body, and which includes a guide roller configured to contact with the photosensitive body and rotate with a movement of the photosensitive body and configured to regulate a positional relationship with the photosensitive body, the guider roller being disposed such that a rotation direction of the guide roller is inclined with respect to the movement direction so as to generate a force for urging the exposing unit to one end thereof in an orthogonal direction when the guide roller rotates, the orthogonal direction being orthogonal to the movement direction and to an optical axis direction of a light emitted from the exposing unit; and a regulating member configured to contact with the one end of the exposing unit to regulate a position of the exposing unit.

  • Patent number: 7781233
    Abstract: In a semiconductor manufacturing method, a metal film is formed on a substrate and heat treated. The relationship between substrate warping and the heat treatment temperature during silicide formation is acquired (S1). A silicide film is formed by forming a metal film on a substrate and heat treating, including substrate measurement during heat treatment (S2). The relationship between substrate warping at heat treatment temperature is determined from the relationship between the warping of the substrate and the temperature for heat treatment and the temperature for heat treatment carried out on the substrate when the warping of the substrate is measured. The difference between found warping and the measured warping is calculated (S4). Whether the difference exceeds a predetermined value is determined (S5). If the difference exceeds a predetermined value, heat treatment conditions are adjusted (S8), but they not adjusted if the difference is no greater than the predetermined value.
