Title: Connection structure for flat cable
Inventor: YAMADA MINORU
IPC: H02G11/02
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To manufacture the terminal part of a flat cable which is compact in size and easily to manufacture. SOLUTION: Only an insulating material 10b on one side of a flat cable 10 is removed to expose only one side surfaces of 1st conductors 10a. In this state, the 1st conductors 10a are electrically connected to 2nd conductors 20 which are placed separately from the 1st conductors 10a with intervals with bonding wires 22. With this constitution, since it is not necessary to form the 2nd conductors 20 into approximately L-shapes but can be simply of rectangular shapes, the cost of a forming die can be reduced, furthermore, since bending allowances which are required for the L-shape forming are not required, protruding dimensions can be reduced and the size of the terminal part of the flat cable can be made compact.

Abstract: PURPOSE:To obtain sufficient flatness even for a fine wiring pattern by etching back first and second resist layers which are substantially united to each other in one body and an interlayer insulating film below the first and second resist layers at an etching quantity at which a wiring layer is not exposed. CONSTITUTION:A first resist layer 4 is formed by performing exposure and development with the inverted pattern of wiring 2 after a resist is applied onto an interlayer insulating film 3. After the resist layer 4 is hardened by baking or UV irradiation, the insulating film 3 positioned to the opening section of the resist mask 4 is etched in a controlled state with an acidic diluted solution of HF, etc. Then a second resist layer 5 is applied and the entire surface is etched by RIE using Freon gas under a condition where the wiring layer 2 is not exposed. Thereafter, the resist layers 4 and 5 are removed with O2 plasma and, in order to improve the interlayer insulating property, an Al wiring layer 7 is formed by sputtering and etching using a chlorine gas after an interlayer insulating film 6 of a silicon oxide containing P is formed by CVD.

Title: Manuifacture of semiconductor element
Inventor: SHIBATA HIROAKI
IPC: H01L21/768
Filed: 1986-08-15
Abstract: PURPOSE:To prevent a base silicide gate film from being directly oxidized thereby to avoid the stepwise disconnection of a polycide gate by forming a conductive mask oxidation protecting film on the silicide gate film which forms a polycide gate electrode. CONSTITUTION:After a first gate 15a forming process, a second gate insulating film 16a, an interlayer insulating film 17, a second polysilicon gate electrode 18a and a silicide gate film 19a are formed. Further, a mask oxidation protecting film 21a made of polysilicon is formed on the film 19 as a second gate, and a mask oxide film 20 is thereafter formed. Since the film 20 is thus formed on the film 21a when forming the film 20, the oxidation does not affect the film 19a. Thus, it can avoid the stepwise disconnection of gate wirings due to a locally accelerated oxidation at the stepwise difference point.

Title: Travel control method for carriage
Inventor: NISHII HISAO
IPC: G05D1/02
Filed: 1991-07-03
Abstract: PURPOSE:To control the horizontal vibration of a carriage part due to torsion by controlling the travel direction of a bogie part in a direction wherein an estimated angle of torsion is eliminated once the angle of torsion is estimated. CONSTITUTION:If the carriage part and bogie part are twisted, a torsion angle estimating element 601 estimates the angle thetas of torsion and a torsion angle constant element 602 obtains a speed correcting voltage based upon the estimated angle thetas of torsion. When the angle thetas of torsion is thus estimated to obtain the speed correcting voltage, the travel direction of the bogie part is controlled to the direction wherein the estimated angle of torsion is eliminated to suppress the torsion of the bogie part and carriage part on an axis, thereby suppressing the vibration of the carriage part on the axis due to the torsion.

Abstract: PURPOSE:To compensate the voltage drop of a piezoelectric element due to the temperature rise of a driver circuit for the piezoelectric element. CONSTITUTION:A transformer or an inductor 1 is controlled by a switching means 2, and electric energy emitted to a piezoelectric element M is stored in the transformer or the inductor 1 while the residual energy of the piezoelectric element M is stored in the transformer or the inductor 1 and returned to the power supply E side.
