Title: Method for cold-rolling aluminum
Inventor: HOSOMI KAZUHIRO
IPC: C10N40/24
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To execute rolling continuously and stably at high speed and under high pressure by taking lubricating oil used for cold rolling part as the liquid mixed with separated water after filtering separated oil and taking the lubricating oil used for the part other than a cold rolling part as the liquid filtering aqueous emulsion before separating into oil and water. SOLUTION: A lubricating coolant used for rolling flows into a collecting tank 10 and is sent to an aqueous emulsion tank 8. Next, a portion of the emulsion in the aqueous emulsion tank 8 is sent into a separating tank 1 through a lubricating coolant feeding conduit 11 and separated into oil and water. After the separated oil is precisely filtered with a filter 2a and the separated water, as necessary, with the filter 2b, they are mixed with a mixer 3 and the emulsion without including an emulsifying agent is reproduced. The reproduced lubricating coolant is again used for rolling. On the other hand, an aqueous emulsion base lubricating oil which is used for a part other than the cold rolling part is taken out as the other portion of the emulsion in the aqueous emulsion layer, sent to the filter 9 and supplied to the rolls other than the biting part of roll.

Title: Voltage detector
Inventor: TAKAHASHI HIRONORI
IPC: G01R31/302
Filed: 1987-06-10
Abstract: PURPOSE:To enable sensitive detection of a voltage at a specified part of an object to be measured, by using a transparent conducting material for a strip line to increase changes in the state of polarization with the incidence of a light beam from the top surface or undersurface of an electrooptic material. CONSTITUTION:Voltage VP at a specified part of an object to be measured is made to travel as traveling wave to a strip line 3 formed on the top surface 2 of an electrooptic material 1. With the traveling of the voltage VP, refractive index at a part right below the line 3 changes in the material 1. At this point, a linearly polarized light beam PB1 is made incident into the undersurface 4 of the material 1 from an electrode 5 made of a transparent conducting material to travel through the material 1 tuned to a progressing speed of changes in the refractive index. The polarization of the light beam PB1 varies with the changes in the refractive index and the light beam is reflected on the line 3 to be outputted from the electrode 5 of the material 1. This causes a substantial change in the polarization of the light beam PB1 while the light beam PB1 reaches the line 3 from the undersurface 4 of the material 1 and while it is reflected on the line 3 to be outputted from the undersurface 4, thereby enabling sensitive detection of a voltage of the object being measured.

Title: Liquid crystal display device
Inventor: YONEDA KIYOSHI
IPC: G02F1/1343
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent unevenness from occurring in brightness of a wide viewing angle liquid crystal display device by arranging an orientation control window formed as a nonexistence area of an electrode film layer, and arranging an auxiliary conductive line overlapping a common electrode only in an area where the orientation control windows are adjacent to each other. SOLUTION: An auxiliary conductive line 35 is arranged in a fine line area where tips of orientation control windows 34 in each picture element are adjacent to each other and a line width of ITO, common electrode 33, becomes narrow. In a pattern form of these orientation control windows, a cross-shaped auxiliary conductive line 35 is formed so as to overlap a cross-shaped ITO line formed by making tip parts of four orientation control windows 34 gather in the area where four picture elements are adjacent to each other. The auxiliary conductive line 35 is arranged to extend over the fine line area of ITO. Therefore, since the voltage is made uniform on the whole area of the common electrode 33, a voltage impressed on the liquid crystal 40 becomes uniform in all picture elements, and this prevents unevenness of brightness.
