Title: Method and apparatus for detecting displacement of wafer protecting tape
Inventor: TSUTAHARA KOUICHIROU
IPC: H01L21/67
Filed: 1985-07-05
Abstract: PURPOSE:To detect the displacement of tape, by projecting light on a semiconductor wafer, which is stuck on semi-transparent tape from the direction of the back surface, and picking up the image of the vicinity of a semiconductor wafer with a one-dimensional image sensor. CONSTITUTION:Visible light 13 is projected on a piece of protecting tape 1, which is stuck on a semiconductor wafer 2. Then, the light is scattered at a protruded part 7 of the tape 1 and only that part is lighted. The lighting part is picked up with a one-dimensional image sensor 10 in the direction perpendicular to the circumference from the upper side of the wafer 2. Then only the protruded part 7 of the tape 1 becomes the 'bright' part, and the other part becomes the 'dark' part. By counting the number of bits at the 'bright' part, the amount of the protruded part of the tape is measured.

Title: Ultrasonic wave flaw detecting method for welded part
Inventor: KANEHARA RYOJI
IPC: G01N29/44
Filed: 1988-06-15
Abstract: PURPOSE:To make it possible to detect the echo of a defect in the vicinity of a surface accurately by approximating the shape of padding with a virtual line connected between the apex of the padding and a terminating end part. CONSTITUTION:An angle delta formed by a virtual line connected by an apex A of padding 11a and a terminating end part B and a surface to be measured is operated by tan delta=Wh/Wl. The height Wh and the width 2W of the padding 11a are obtained beforehand. A beam length from a certain point P which is located at a distance Y1 from the center of the padding 11a to the virtual line S of an ultrasonic wave beam which is inputted into the padding 11a at an incident angle theta is given by the expression W0=Y(1-1/tan delta.tan theta)/sin theta, where Y is a distance (y1+y2) from an intersection C between the virtual line and the surface to be measured to the incident point. Therefore, W1-W0<=0 and W2-W0>=0, where W1 is the beam length from a reflecting source at the inner side of the virtual lines and W2 is the beam length from the reflecting source at the outer side. Then, only the value at the time of W1-W0<=0 is recorded. In this way, the defect in the vicinity of the surface of the padding can be accurately detected.

Abstract: PURPOSE:To extend the life of horning head by regulating the wear of grindstones thereof by groups through connecting same number of regulating members as the number of groups of the grindstones with the lower part of the rod which protrudes therefrom and regulates the grindstones of more than two, and through connecting each of the regulating members by means of a screw member to each other. CONSTITUTION:In case each of grouped grindstones 17a and 17b, or 17c and 17d controlled by a regulating rod 38 or 33 is worn, the descending quantity of the regulating rod 38 or 33 is regulated by increasing the step numbers of a stepping motor of a horning machine on the basis of the grindstone 17b or 17d of the same group. The wear difference between the grouped grindstones 17a and 17b is regulated by rotating a second regulating member 20b by means of a regulating pin 29. The wear difference between the grouped grindstones 17c and 17d is also regulated by rotating a fourth regulating member 20d by means of a regulating pin 30. It is thus possible to widely extend the life of grindstones even if the wear quantities of the grindstones differ to each other.
