Patent JP-S6231412-A (JP)
Title: Position controller
Inventor: WAKAO TERUYOSHI
IPC: B60G17/015
Filed: 1985-07-31
Abstract: PURPOSE:To avoid the useless position control and to improve the durability of a position controller by shifting a movable member among the 1st stop position where the shift of the movable member is controlled only in a single direction, the 2nd stop position where the shift in the opposite direction is controlled and the 3rd stop position set between the 1st and 2nd stop positions. CONSTITUTION:A command means 18 delivers a command in response to an external input to select one of the 1st-3rd stop positions A-C of a position controller. This command is received by the 1st control means 20 and the 1st driver 12 is energized by a command which shifts a movable member 10 among positions A-C. Then the member 10 is shifted among positions A-C by the means 20. Thus the 1st storage means 22 stores a fact that the member 10 is set at positions A-C into a present position memory 24. When the means 18 produces a command to shift the member 10 to the position B, both the driver 12 and the 2nd driver 16 are energized by the 2nd control means 26 as long as a memory 24 contains the memory contents. Thus the member 10 is stopped at the position B.

Title: Forming process of optical waveguide
Inventor: ALAM MUHAMMAD ASHRAFAL
IPC: H01S5/026
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a process for forming a waveguide. SOLUTION: In this process, an optical waveguide is formed by depositing a compound semiconductor material on a substrate with chemical vapor deposition. At this time, since a dielectric mask affects the deposition rate of the compound semiconductor material on the substrate in its area in the vicinity of the mask, distribution of the waveguide to be formed with a mask having selected mask dimensions, is subjected to modeling and compared with a desired distribution. When the modeled distribution is not allowably similar to the desired distribution, the mask dimensions are corrected. Distribution of the waveguide to be formed with the corrected mask having corrected dimensions is again subjected to modeling and the modeled distribution is compared again with the desired distribution. This process is repeatedly performed until the modeled distribution becomes sufficiently similar to the desired distribution. After the mask dimensions are finally selected, a mask is formed on the substrate and a compound semiconductor waveguide is formed on the substrate by using selective area growth(SAG).
