Title: Double facer
Inventor: TAKENAKA HIROYUKI
IPC: B32B29/08
Filed: 1988-02-26
Abstract: PURPOSE:To enable weight rollers to apply uniformly loads in the width direction of a sheet along the deformation of hot plates by gradually decreasing the crown quantity given to respective groups of weight rolls corresponding to the unit hot plates from the double facer inlet toward the outlet. CONSTITUTION:On arranged hot plates 9, one or more weight rolls 10 are mounted respectively via a belt and a corrugated board sheet and a group of the weight rolls mounted on one hot plate 9 is given with the crown of the same quantity. The crown quantity of the respective groups of the weight rolls 10 on respective hot plates is gradually decreased from the double facer inlet toward the outlet. As the corrugated board sheet runs, the heat on the upper surfaces of the hot plates 10 is taken away and each hot plate 9 is deformed into concave shape. Since the closer the inlet of the double facer, the larger the taken away heat value, the deformation degree becomes large, and the deformation of the hot plate becomes small as it approaches the outlet. According to the constitution of the weight roll, any weight rolls 10 on the hot plates 9 come to act along the deformation of the hot plate, and it becomes that the uniform pressure is applied in the width direction of the corrugated board sheet.

Title: Forming method for resist pattern
Inventor: TAKIGAWA TADAHIRO
IPC: H01L21/30
Filed: 1982-03-17
Abstract: PURPOSE:To eliminate the variation of the line width of the resist pattern by selecting the gru n range of electron beams and the combination of a resist and a developer. CONSTITUTION:In the resist pattern formed by irradiating electron beams to the resist 6, the line width is made wider than width designed at a position 7a corresponding to the thick section 7 of resist film thickness, and made narrower than that at a position 8a corresponding to a thin section 8. Since the variation of line width largely depends upon not only the thickness of the resist but also the change of reflected electron intensity in an edge section, the variation of line width due to the change of reflected electron intensity can be eliminated when selecting the acceleration voltage of electron beams in which the ratio G/h of the gru n range G of electron beams to foundation uneven height (h) reaches 7 or more. The variation of film thickness can be reduced more by using PMMA (poly-methyl-metha-acrylate) as the resist and IAA (iso-amyl-acetate) as the developer.

Abstract: PROBLEM TO BE SOLVED: To provide a method for structure-estimating a compound noun containing unknown words by collecting keys which actually appear in the other places in a document and combining them. SOLUTION: Words obtained by morpheme-analyzing a compound word and which cooccur with a core word are retrieved by using pattern matchers. A cooccurrence example is stored in a data storage area. When the unknown words are detected, they are stored in an unknown storage area (1006 and 1007). A cooccurrence pattern is retrieved on the detected unknown words and a result is added in a cooccurrence data storage area (1008 and 1009). Data on a modification likelihood storage area is constituted from a cooccurrence data base (1010). When the unknown word is detected, a morpheme analysis result is corrected (1011) and a modification relation between the corrected word groups is estimated by using data of the modification likelihood storage area (1012).
