Title: Detector for breakage of screen in screen printer
Inventor: OTANI YASUAKI
IPC: B41F33/14
Filed: 1986-03-14
Abstract: PURPOSE:To exactly detect damage of screens by providing a sensor to detect the breakage of the screen in a screen frame. CONSTITUTION:The change of a screen frame 2 in operation is always detected by a sensor 4, and when the screen of the frame 2 is broken, a change (e.g., deflection of 0.01-0.6mm) in the frame 2 when broken is detected and is taken out as a signal indicating the breakage of the screen. It is thus made possible that all drive mechanism can be stopped by signals from the sensor 4 when the screen is broken by connecting the screen 4 with the drive mechanism of printer. The flowing-down of ink on printer during the breakage of the screen 4 can thus be completely prevented, and occurrence of defective print products can be prevented significantly.

IPC: G01B9/02
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus which can measure a wave front aberration with high accuracy, by turning a group lens to be inspected or a single lens to be inspected measuring the wave front aberration in at least two directions, computing and separating a component following its rotation and a component other than its rotation, and detecting the rotation asymmetric component of the wave front aberration. SOLUTION: A rotation mechanism 4 which turns a group lens to be inspected or a single lens 3 to be inspected is installed. A null optical system 6 and a TS lens 2 are aligned in advance in such a way that their mutual decentering becomes small and that their mutual interval is brought close to a design value. When the generation of an aberration due to the group lens to be inspected or the single lens 3 to be inspected is small and when the null optical system 6 is not required, the optical system 6 is deleted, and an optical system is constituted in such a way that an inspection luminous flux is directly incident on a reflecting mirror 7 from the lens 2 and the group lens to be inspected or the single lens 3 to be inspected.  In this manner, when the group lens to be inspected or the single lens 3 to be inspected is turned, the asymmetric component of a wave front aberration is obtained. As a result, even when a master single lens or a master single lens is not prepared, the rotation asymmetric component of the wave front aberration can be measured absolutely.
