Title: Preparation of filter using filter paper
Inventor: MIYOSHI JIYUNICHIROU
IPC: B29C45/14
Filed: 1984-04-03
Abstract: PURPOSE:To prevent deformation of filter paper and frame body in a process for prepg. a filter using filter paper wherein a square frame body is prepd. by injection molding on the periphery of a bellows-shaped filter paper, by fixing the shape of the frame body immediately after injection molding, and an angle between a wall face of the frame body and the filter paper. CONSTITUTION:The filter is formed immediately after injection molding to a construction that the periphery of the filter paper 4 is fixed to a square frame body 3 comprising a synthetic resin with approximately 90 deg. angle of each corner and approximately 45 deg. angle (a) between the edge lines or valley lines of the bellows-shaped filter paper and the wall face of the frame body. The filter is prepd. by setting a filter paper in a cavity for molding said square frame body in such a manner that the angle between the side face of the cavity and the edge lines or the valley lines of said filter paper is 45 deg., and injection molding the frame body to the periphery of the filter paper. By this constitution, deformation of the filter paper and the frame body due to shrinkage after molding until cooling, is prevented.

Title: Insert molding method
Inventor: OKABE YASUHIRO
IPC: B29C45/26
Filed: 1986-03-25
Abstract: PURPOSE:To suppress the amount of deformation of an insert by inclining the insert itself and/or setting an edge dam on the mold in such a way that the injecting pressure of a raw material is only applied on one side of the insert and by supporting the part of the insert being floated from the mold by means of supporting parts from the side of the insert where the injecting pressure of the material is not being applied. CONSTITUTION:An edge dam 15 and supporting pins 17 are set on a bottom force 7. The edge dam 15 has a fan-shaped cross-section whose curved surface is faced in the flow direction of a material and have about the same height as that of the edge of an insert 5 at the material injection side. 8 penetrating holes 21 are formed on the edge part of the insert 5 and the material can be thereby easily reached the back side of the insert 5. When the material is injected in a cavity 13, the flow is concentrated on the upper side of the insert 5 as shown by arrow marks by means of the edge drum 15. The part A of the insert 5 faced to the material injecting side is not thereby pressed by the total pressure of the material flow. If the insert is deformed by the static pressure of the material flow, the amount of deformation is small and is not detectable in its appearance as it is being supported from the lower side by means of the supporting pins 17.

Title: Manufacture of semiconductor device
Inventor: YAMASHITA SAEKO
IPC: H01L21/027
Filed: 1990-03-16
Abstract: PURPOSE:To enable detection even when the shape of an alignment mark is deformed to some extent, by performing alignment after the surface of the alignment mark is subjected to surface roughening treatment. CONSTITUTION:At the time of alignment of a photomask and a wafer in an exposing process, the surface of an alignment mark 2 formed on the wafer is subjected to a surface roughening treatment, and then alignment is performed. By roughening the surface of the alignment mark 2, the form of a detected signal is disordered, but the signal level is increased. That is, when an epitaxial layer 4 is grown on a substrate so as to cover the alignment mark 2, the bottom part surface of the alignment mark 2 is roughened and made to reflect on the epitaxial layer, thereby increasing the intensity of scattering light of the mark part of the epitaxial layer 4. Hence the alignment mark 2 can be detected even when the mark shape is deformed to some extent.
