摘要： A method for manufacturing a circuit board having a through-hole for defining via hole, which has a sloped inner wall tilted at a desired tilt angle &thgr;, is provided. The through-hole has an inverted-trapezoidal cross-section and is made using a photomask having a via hole pattern including a light-shielding pattern corresponding to the bottom of the through-hole, and pluralities of light-shielding strips and translucent strips which are arranged alternately and substantially parallel to one another, the pluralities of light-shielding strips and translucent strips corresponding to the sloped inner wall of the through-hole. The tilt angle &thgr; is determined using a polynomial approximation of degree n: f ⁡ ( s ) = θ = φ ⁢ ∑ k = 0 n ⁢ C k ⁢ s k wherein s is the width of the light-shielding strips and &phgr; is a constant relating to the exposure conditions, and is in the range of about 0.17 rad

摘要： An apparatus for treating synthetic resin waste containing thermoplastic synthetic resin and various foreign matter which often contain volatile matter. This apparatus makes it possible to produce articles, from the resin waste, having good mechanical properties by first driving off volatile matter. The apparatus is especially usable for producing long, bar-shaped products, large-sized cylindrical products, piles, sleepers, or molding flasks for concrete works.
