IPC: G02F1/1368
Filed: 1992-02-27
Abstract: PURPOSE:To decrease deterioration of resistivity of a conductive film and to obtain low resistivity by forming a multilayered transparent conductive film on a silicon oxide film by sputtering a quartz target in a specified gas atmosphere. CONSTITUTION:A carrier 15 can freely move in sputtering rooms 1, 2 and between these rooms. A silicon oxide film is formed on a substrate 14 on the carrier 15 by sputtering in the sputtering room 1 containing an oxide atmosphere of In2O3 with 10wt.% SnO2, while the carrier 15 is moved at a specified speed on the target ST. Then the carrier is made to pass through a valve 3 between the sputtering rooms 1, 2 and sent to the sputtering room 2. In the sputtering room 2, a transparent conductive film is continuously formed on the silicon oxide film on the substrate 14 by sputtering in Ar gas mixed with O2 gas while the carrier is moved at a specified speed on the target AT. Thus, an oxide film with high oxidization degree is formed on the substrate 14, the resistivity of the transparent conductive film after formed can be decreased.

Abstract: PURPOSE:To decrease the stress load on optical fibers in the stage of exerting side pressure thereto by making independent side pressure members and a tension member and inserting or fixing the tension member as a fiberous tensile body into the sheath of a flat cable. CONSTITUTION:The two optical fibers 1a, 1b are disposed at approximately the center in the lateral direction of the sheath 3 for an flat optical fiber in the positions symmetrical with the central axis. Two pieces of the side pressure members 5a, 5b which consist of FRP or copper and are made into the bar shape having the diameter larger than the diameter of the fibers 1a, 1b are disposed on both sides thereof. The members 5a, 5b are deformed earlier than the optical fibers 1a, 1b to decrease the pressure exerted to the fibers 1a, 1b when the pressure in a vertical direction is exerted to the flat optical fiber. The tension member 6 consisting of a arom. polyamide fiber or the like is disposed above the fibers 1a, 1b to provide a function to protect the fibers against tensile force. The position for disposing the member 6 is not as strict as for the members 5a, 5b. The tension member is thus disposed in any position where the tensile stress of the fibers 1a, 1b can be absorbed.

Title: Image rotation system
Inventor: ISHIKAWA YASUNORI
IPC: G06T3/60
Filed: 1985-03-04
Abstract: PURPOSE:To speed up rotation processing when image consisting of binary data is rotated by 45 deg. at every time by reducing the row-directional or column directional number of picture elements before the rotation to about 1/2<1/2> and then moving the image, and increasing the number of columns or rows by about 2<1/2> times. CONSTITUTION:When an original image in figure (a) is rotated counterclockwise by 45 deg. around a picture element A11, picture elements A11-A18 in the 1st row are rotated by 45 deg. as they are to form the 1st row in figure (b). Then, the length of picture elements becomes 2<1/2> time, so this is adjusted by thinning out picture elements and moving the image. This thinning-out processing is applied to all the rows. Further, when picture elements A21-A28 in the 2nd row in figure (a) are rotated by 45 deg. to form the 2nd row in figure (b), picture element intervals between the 1st row which is moved last and the 2nd row become short to 1/2<1/2>, so rows in figure (a) are repeated properly and moved. Namely, the 2nd row in figure (a) is thinned out properly and moved to the 2nd row in figure (b), and then the same 2nd row is thinned out properly and moved to the 2nd row again.
