Title: Emulsifier
Inventor: HIGUCHI HISAO
IPC: C09K23/18
Filed: 1989-11-20
Abstract: PURPOSE:To obtain an emulsifier optimum in the preparation of an emulsion excellent in glossiness and especially, in water repellency by using a specific di-long chain alkyl quaternary ammonium salt as an essential component. CONSTITUTION:An emulsifier is obtained by adding a quaternary ammonium salt represented by formula I (wherein R1 and R2 are a 20-22C alkyl or alkenyl group, R3 is a 1-3C alkyl group, R4 is a 1-3C alkyl group or a 2-4C polyoxyalkylene group and the addition mol number thereof is 1-50 and X is a halogen atom, -CH3SO4 or -C2H5SO4) as an essential component. The quaternary ammonium salt represented by formula I is obtained by converting fatty acid of fish oil or rapeseed oil to di-long chain alkylamine and quaternizing said amine as it is by alkyl halide or adding 2-4C alkylene oxide thereto before quaternizing the same. A film having good water repellency can be formed by the emulsion prepared using this emulsifier and the emulsion imparts excellent gloss as car wax.

Title: Operation temperature detecting method for solid electrolyte type sensor element
Inventor: CHO EKISAN
IPC: G01N27/406
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To accurately detect an operation temperature of a sensor by measuring an electromotive force between a third electrode and a reference electrode provided on a solid electrolyte. SOLUTION: In this sensor element, a solid electrolyte 1 is provided with a third electrode 7 for detecting temperature air-tightly sealed by a seal 8, while the third electrode 7 is connected to a control circuit 5. When the sensor element is heated with a heating heater 4 in a measurement gas atmosphere to be operated, an electromotive force is generated between a detection electrode 2 and a reference electrode 3. This electromotive force is a gas density measurement potential. An electromotive force is generated between the third electrode 7 and the reference electrode 3 due to a chemical potential difference between alkaline metal ions of both the electrode 7, 3. This electromotive force is a temperature measurement potential. Accordingly, by measuring the electromotive force generated between the reference electrode 3 and the third electrode 7, an operation temperature of the moment can be accurately measured according to a temperature characteristic graph with respect to a potential between the third electrode 7 and the reference electrode 3. By controlling the heating heater 4 or correcting the gas density measurement potential on the basis of the measured operation temperature, an accurate gas density can be displayed on a display part 6.

Title: Roll for preventing heat crown
Inventor: HIROTA YOSHIAKI
IPC: C21D9/56
Filed: 1992-10-19
Abstract: PURPOSE:To uniformize the temp. distribution on the surface of a roll and to prevent the generation of heat crowns by fitting a roll shell having high thermal conductivity to the outside part of the roll shaft and arranging a gap or a heat insulating layer between the roll shaft and the roll shell at a center part. CONSTITUTION:The roll shell 2 having high thermal conductivity is fitted to the outside part of the roll shaft 1 through the gap 3 or the heat insulating layer. The width of the gap 3 or the heat insulating layer is wider than the passing range of a carrying material 6 of a metal strip, etc. When a part of the roll shell 2 becomes high temp. by coming into contact with the carrying material 6, since the roll shell 2 has the high thermal conductivity, the heat is transferred to the other part and this heat flux is directed to the transverse direction of the roll because of the presence of the gap 3 or the heat insulating layer. Thus, the temp. of the roll shell 2 surface is uniformized in the transverse direction. Therefore, the generation of the heat buckles in the case of switching to the wide width material and the heat crowns to the roll shell 2 can be prevented.
