IPC: G03G21/10
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus with a simple structure which removes each developer remaining on each photoreceptor drum after transfer and reuses the removed developer. SOLUTION: The image forming apparatus is provided with a transporting route forming part 3 which forms a transportation route 7 to guide residual toner caused from a plurality of image forming stations Pa to Pd in common, and a transport means 4 which transports the residual toner housed in the transporting route 7 by the rotation of a screw 15 to discharge holes formed at both ends of the transporting route forming part in the axial direction. A screw 15 can transport the residual toner in the transportation route by dividing it into two direction from a rotating direction change point P, respectively. Thus, the transportation of the residual toner is carried out on the common transportation route 7, which eliminates the need for providing the transportation route 7 and the transport means 4 for each image forming station Pa to Pd, and simplifies the structure. The recyclable residual toner is obtained by discharging one kind of residual toner from one discharge hole.

Title: Method of detecting aberration of optical imaging system
Inventor: DIRKSEN PETER
IPC: G03F1/08
Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a method of detecting aberrations of an optical imaging system which can measure various aberrations independently of each other based on the principle different from the conventional one. SOLUTION: The aberrations of the imaging system (PL) can be detected in an accurate and reliable way by imaging, by means of the imaging system, a circular phase structure (22) on a photo resist (PR), developing the resist and scanning it with a scanning detection device (SEM) which is coupled to an image processor (IP). The circular phase structure is imaged in a ring structure (25) and each of several possible types of aberrations such as coma, astigmatism, and three-point aberration causes a specific change in the shape of the inner contour (CI) and the outer contour (CE) of the ring, so the aberrations can be detected independently of each other. Each type of aberration is represented by a specific Fourier harmonic (Z-), which represents higher or lower order sub-aberrations. The novel method enables to determine these aberrations.  The novel method can be used for measuring a projection system for a lithographic projection equipment.
