Title: Servo controller
Inventor: SHIMADA AKIRA
IPC: G05D3/12
Filed: 1989-09-25
Abstract: PURPOSE:To improve the control performance by providing a function which simultaneously performs compensation to apparently erase the disturbance load with the positive feedback of an estimated disturbance load as well as speed feedback compensation using the estimated speed. CONSTITUTION:The position control operation part 3 of a servo controller 1 compares the data of a position command 5 with the position detection signal 6 of a control object and uses the data of the estimated speed 10 to perform the operation required for control and outputs a driving force command 10a. Meanwhile, the driving force 8 and the position detection signal 6 are inputted to a disturbance load speed observer 4, and the observer 4 outputs the estimated disturbance 9 and the estimated speed 10. The estimated disturbance load 9 is added to the output 10a of the position control operation part 3 to obtain the driving force 8. Since disturbance torque elimination and estimated speed feedback are simultaneously performed in such a manner, stable control is realized even when the speed is so low that speed ripple is apt to occur.

Title: Resistance value adjusting method of transparent wiring in organic el display device
Inventor: TAMAGAWA TATSUO
IPC: H05B33/26
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To easily adjust a resistance value by adjusting the resistance value of wiring by adjusting a thickness of transparent wiring. SOLUTION: Since a segment electrode A1 is required to impress high driving voltage having the large area, a thickness T1 of transparent wiring B1 connected to the segment electrode A1 is set large. While, the other segment electrode is only required to impress low driving voltage having the small area, a thickness of transparent wiring connected to the segment electrode is set smaller than the thickness T1 of the transparent wiring B1. Thus, a resistance value of the transparent wiring B1 is set lower than that of the other transparent wiring, driving voltage according to the area of respective segments is impressed on the respective segment electrodes, and electric current density between the respective electrodes is uniformized, so that the respective segments emit the light in uniform luminance. This resistance value adjusting method is particularly advantageous to complicated wiring since the transparent wiring can be arranged in a small space.

Title: Pattern forming method
Inventor: YAMANAKA RYOKO
IPC: H01L21/3065
Filed: 1993-10-05
Abstract: PURPOSE:To provide a fine pattern having good shape by causing a relaxation reagent as an organic solvent to penetrate a resist film before the diffusion of a sililated molecule, and selectively relaxing a giant molecule in a resist. CONSTITUTION:A far infrared radiation is radiated on a resist film 4 formed on a processed substrate 5 via a mask 2, thereby bridging an exposure sections 3. Thereafter, the substrate 5 is immersed in liquid containing a polymeric organic solvent 4 as a relaxation reagent, and before the diffusion of a sililated molecule in the film 4, the relaxation reagent is selectively made to penetrate an non-exposure section not bridged and the polymeric chain of the resist is thereby relaxed. As a result, the molecule of a sililating reagent in a relaxed zone 6 comes to have a larger diffusion constant and the zone 6 is thus selectively sililated, thereby forming a sililated layer 7. Also, this resist film 4 is developed by using a plasma 8 and the selectivity of sililation between exposed and un-exposed sections is thereby improved. In addition, even an optical image of low contract can be resolved, and a fine pattern can be formed to good shape.
