Title: Determination of carcinogen and assay base thereon
IPC: C07K16/00
Filed: 1992-03-10
Abstract: PURPOSE: To perform assay based on the difference between a mutant allele and a corresponding wild-type allele, in particular between a carciogen and a primordial carciogen. CONSTITUTION: When a host is immunized, an antigen producing an antibody having capability for detecting a DNA structure causing a functional difference between a wild-type allele and a mutant allele is produced. An antibody is produced for detecting mutation of a wild-type allele to a mutant allele by immunizing a host under conditions where the host produces an antibody.

Title: Copying paper having drop color pattern
Inventor: YAMADA YASUO
IPC: G03G21/04
Filed: 1979-05-01
Abstract: PURPOSE:To obtain the drop color copying paper on which a printed pattern is able to be seen sharply, by adding a fluorescent whitening agent to the paper with a color pattern printed. CONSTITUTION:Bis(triazinylamino)-stilbenedisulfonic acid derivative or the like fluorescent whitening agent makes it difficult to copy a printed pattern without lowering its visibility too much. When the paper treated with the whitening agent exhibits a fluorescent whitening rate of 0.5% or more, fluorescence enhances effectively drop color characteristics. Use of such paper permits a printed pattern not to be copied by a copier high in low density reproductivity and yet the printed pattern to be seen sharply.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing the quantity of material being removed at the time of etching off a residue HF on a semiconductor wafer after it is taken out of an HF etching bath. SOLUTION: A semiconductor wafer is immersed into an HF bath of NH4 buffer solution of nonfluid HF being held at the room temperature. The wafer is then transferred to a cleaning bath of deionized water (required time is 1 sec or less) and subjected to cleaning for about 5min. Temperature of the cleaning bath is at least 5 deg.C lower than that of the HF bath. When the wafer is being transferred from the HF bath to the cleaning bath, TEOS dielectric material on the water is removed through the etching action of a residual etchant on the wafer. According to the method, etching with the HF of the TEOS dielectric layer is stopped quickly and the quantity of TEOS to be removed is extremely small.
