Title: Position detecting equipment and method which use oblique optical axis optical system
Inventor: MIYATAKE TSUTOMU
IPC: G03F9/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To enable highly precise alignment capable of position detection in the course of exposure, by arranging a second observation optical system which has a different magnification and forms the image of a light reflected by a partial reflection mirror, on the optical axis of a first observation optical system which forms images of lights scattered from a wafer and a mask. SOLUTION: When a wafer mark and a mask mark formed on a wafer 11 and a mask 12 have edges, illumination light is scattered by the edges. Out of the scattered light, a light entering a lens 22 is converged in a lens 22, and a part of the light passes half mirrors 23 and 26A, and forms an image on the imaging surface 29A of an image detecting equipment 21A. The imaging magnification on the imaging surface 29A is e.g. 20. Out of the scattered lights, a light reflected by the half mirror 26A is reflected by a mirror 26B, converged by a relay lens 28, and forms an image on the imaging surface 29B of an image detecting equipment 21B. The imaging magnification on the imaging surface 29B is, e.g. 80-100. Two observation optical systems different in magnification are arranged in the above manner.

Title: Developing device and image forming device
Inventor: NAKAZONO YUSUKE
IPC: G03G15/08
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain a satisfactory, high quality image by distributing the contact parts of a gap maintaining members with an image carrier between several areas so that they are discontinuous with each other in the directions of their peripheries and length, thereby keeping a gap between the developer carrier and image carrier constant and preventing white banding. SOLUTION: Caplike SD rollers 16, which can be fitted on non-image parts on both ends of a developing sleeve 3 in its longitudinal direction, are used as the gap maintaining members for maintaining a gap (SD gap) between the developing sleeve 3 and the photoreceptor drum 1. The contact parts of the peripheries of the rollers 16 with the drum 1 are longitudinally spiral. Thus, because the contact parts are distributed but not concentrate in one point, scattered toner is prevented from being fused in a mass on the drum 1 even if the scattered toner from the image area of the sleeve 3 is pressed between the contact part of the roller 16 and the drum 1. Therefore, the width of the SD gap is prevented from being increased but is kept constant, development is surely carried out in any cycle of the drum 1, and the sharp, high quality image can be obtained.

Abstract: PURPOSE:To transport a sheet in stable manners by controlling the time phase difference between the ac voltages applied onto an electricity - mechanical energy converting means of each vibration body so that the phase difference detected by a phase difference detecting means becomes zero. CONSTITUTION:During the transport of a sheet, if the time phase at the spacial position of the progressive vibration wave formed on the first vibration body delays for the time phase at the spacial position of the progressive vibration wave formed on the second vibration body 5, the phase of the output signal of a piezoelectric element 2 for detecting the vibration state of the vibration body 1 delays for the phase of the output signal of a piezoelectric element 6 for detecting the vibration state of the vibration body 5. Therefore, the output signal of a phase difference detector 10 becomes a negative value, and the output signal of a low path filter 11 reduces. Therefore, the phase shift control signal of a voltage control type phase shifter 12 becomes negative, and the phase of the output signal of the phase shifter 12 is delayed, and the phase of the ac voltage applied onto the piezoelectric element divisions 7 and 8 of the vibration body 5 is delayed, and the time phase of the progressive vibration wave formed on the vibration body 5 is delayed.
