Abstract: PURPOSE:To remove a secondary reflection image by providing a photodetecting means with a 1/4-wavelength plate which inputs reflected light and converts it into linear polarized light and a polarizing plate whose transmission axis is aligned so that the primary reflected light of the linear polarized light is transmitted. CONSTITUTION:The light emitted by a laser light source 4 becomes slit light 8 through a cylindrical lens 6 and is converted by the 1/4-wavelength plate 7 into circular polarized light, which illuminates the surface of a body to be welded consisting of a vertical plate 9 and a lower plate 10.

At this time, the polarizing plate 13 is arranged having the transmission axis in the vibration direction of the linear polarized light. Consequently, the majority of secondary reflected light differing in polarization state is cut off from the polarizing plate 13 and the primary reflected light is projected mainly. Then the light is imaged by an image forming lens 15 and converted photoelectrically by an image pickup means 17 and an image processing part 19 removes noises to detect the position of a weld line, so high-accuracy position detection is performed.

Title: Resin coated sand for shell mold
Inventor: SUZUKI NORIAKI
IPC: B22C1/22
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To dissolve a trouble caused by static electricity at the time of transporting sand grain. SOLUTION: In the resin coated sand grain composed of the sand grain and the resin coating layer of thermosetting resin covering the surface of the sand grain, white carbon is stuck onto the surface of the resin coated layer. Since the white carbon contains crystal water under state of super fine powdery silicon dioxide (SiO2 .nH2 O), it is supposed that OH group and crystal water electrically discharge to the out of the system without storing. Further it is considered that the white carbon itself functions as lubricant and acts to reduce the friction of the resin coated sand grains to each other. Therefore, even in the case of using novolak type phenol resin having little free phenol content in order to improve the working environment in a molding work, the large electric charge preventing effect can be displayed by adding the white carbon.
