Title: Light beam scanner
Inventor: NARITA MASAKI
IPC: B41J2/44
Filed: 1994-12-28
Abstract: PURPOSE: To prevent heat generated by a motor from remaining in an optical unit by providing a motor housing so that the passing window of the motor housing may be aligned with a hole formed in an optical housing for storing a lens and a mirror in an airtight state. CONSTITUTION: A rotary polygon mirror 3 is stored in the airtight state by arranging a transparent member 13 so as to close the window part 12 of the motor housing 11. The motor housing 11 is attached so that the motor 14 may be arranged outside the optical housing 10 and also arranged adjacent to the side wall 15 of the optical housing 10, and the window part 12 with the transparent member 13 is positioned opposite to the hole 16 formed in the optical housing 10 with the transparent member 13 interposed. Thus, an exit beam from a semiconductor laser unit 1 reaches the rotary polygon mirror through the hole 16, the transparent member 13 and the window part 12, conversely, the light reflected by the rotary polygon mirror 3 reaches the inner part 17 of the optical housing 10 through the window part 12, the transparent member 13 and the hole 16.  Thus, the temperature rise in the optical housing is prevented.

Abstract: PROBLEM TO BE SOLVED: To quickly set an inspection region with satisfactory hondleability by providing an inspection region setting means on a displayed wafer map and as well as displaying the number of inspection chips, an inspection area, estimated inspection time or the like, together with a wafer map display image. SOLUTION: A region to be inspected is clicked or dragged (chip selected) for specification from among effective chips on a wafer map 101 and a map in chips. Since all the chips in a wafer are defaulted to be a region to be inspected, desired chips or regions can be specified to set an inspection region, while alternately, chips or regions which are not to be inspected can be specified thereby setting a region which is not to be inspected. In this case, the inspection region can also be specified by referring to a scanning electron microscope(SEM) image displayed on a right-hand screen 105. Thereafter, a sampling rate is selected from a combo box of a sampling rate input region 103. The number of chips inspected, the total number of chips, the inspection area, the sampling rate and estimated inspection time are respectively displayed on the lower right of the screen.

IPC: A61B6/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent an object of inspection from being exposed to unnecessary X-rays and enhance the operability of a diaphragm opening by controlling the diaphragm opening of a rectangular diaphragm on a second power and controlling the diaphragm opening of a circular diaphragm on a first power. CONSTITUTION:An X-ray diagnosis equipment is provided with a circular diaphragm 21, a rectangular diaphragm 22, a variable power means and an optical system 5, etc. The circular diaphragm 21 limits circularly the X-rays incident on an object of inspection 3 according to diaphragm opening. The rectangular diaphragm 22 limits retangularly the X-rays incident on the object of inspection 3 according to the diaphragm opening. The variable power means varies a first power between an X-ray image on an input face 41 of an light image covering means 4 and an optical image of an output face 46. The optical system 5 varies a focal distance to vary a second power between an optical image of the light image converting means 4 and an optical image surrounded with an image pickup means 6. On the second power varied by the optical system 5, the diaphragm opening of the rectangular diaphragm 22 is so controlled as to control the diaphragm opening of the circular diaphragm 21 on the first power. This enhances the operability of the diaphragm opening without exposing the object of inspection 3 unnecessarily to X-rays.
