Abstract: PROBLEM TO BE SOLVED: To enable formation of an interlayer insulating film having a flat surface, on a step portion even in a case where a large step portion exists in a base interlayer film in a multilayered wiring structure, to ensure a sufficient DOF margin by using normal, illumination in photolithography, and to stabilize the thickness of a resist film and an image at a wiring process, by mitigating the influence of the step portion, and by improving wiring-image control by dry etching to use the formation of interlayer film in a multilayered wiring structure connected via connection holes. SOLUTION: A first stopper film 7 is formed only on a high-step region of a first base interlayer film 6 formed on a base layer. A second base interlayer film 8 is formed on the first base interlayer film 6 and the first stopper film 7, and a second stopper film 9 is formed only on a low step region of the second base interlayer film. Next, only the high step region of the second base interlayer film is etched to expose the first stopper film 7, and the first and the second stopper films are removed by etching.

Title: Mixer
Inventor: ITO KENJI
IPC: H03D7/00
Filed: 1989-06-12
Abstract: PURPOSE:To reduce the power level of a local oscillation signal (LO signal) and an unnecessary signal to be leaked to an intermediate frequency signal (IF signal) terminal with simple configuration by providing one resonance circuit at least in a low pass filter for IF signal (LPF for IF signal). CONSTITUTION:One resonance circuit 12a or 12b is provided at least between the input/output terminals of an LPF 8 for IF signal. When the resonance frequencies of the resonance circuits (12a and 12b) are set to an LO signal frequency or a spurious signal frequency, a block characteristic is generated between the IF signal terminals from shot key diodes 5a and 5b. Thus, by this block characteristic, the output power level is reduced with the simple configuration for the LO signal or unnecessary spurious signal to be leaked to an IF signal terminal 3.

Abstract: PURPOSE: To obtain a wide visual angle by adding an optically active compd. which gives a helical structure to the orientation of liquid crystal molecules of a liquid crystal having negative dielectric anisotropy, forming a liquid crystal layer and orienting the liquid crystal molecules perpendicular to the plane of an orienting film. CONSTITUTION: Orienting films 23, 27 are formed by applying org. silane compd. films on transparent electrodes 22, 26 formed on glass substrates 21, 25, respectively. These substrates are disposed with the orienting films 23, 27 facing each other to form a space, and a liquid crystal layer 32 is held in this space to constitute a liquid crystal cell 34. This liquid crystal layer is prepared by adding an optically active compd. which gives a helical structure to the orientation of liquid crystal molecules, for example, by adding cholesterisnonate by 2%, to a liquid crystal material having negative dielectric anisotropy. Further, polarizing plates 28, 29 with the polarization directions perpendicular to each other are disposed on the both sides of the liquid crystal cell 34 to obtain a liquid crystal element 35.  The liquid crystal molecules in the liquid crystal layer 32 are oriented perpendicular to the film plane of the orienting films 23, 27. Thereby, when enough voltage is applied, the liquid crystal molecules are released from the control of the orienting films so that the orienting axes of liquid crystal molecules are randomly distributed in the plane parallel to the substrate plane.

Abstract: PURPOSE:To make quantitative analysis with high accuracy by titrating a sulfuric acidic rhodium plating liquid with an aq. basic soln. by a potentiometric titration method and determining the neutral equiv. point of the sulfuric acid and aq. basic soln. and the neutral equiv. point of Rh<3+> and the aq. basic soln. CONSTITUTION:NaOH, KOH, etc. are used as the aq. basic soln. in the stage of titrating the rhodium plating liquid with the aq. basic soln. by the potentiometric titration method. The 1st equiv. point P is determined by titrating the aq. sulfuric acidic rhodium soln. which is a sample with the aq. basic soln. and the volume A of the aq. basic soln. required for the titration is determined. The Rh<3+> is tigrated in succession to the above and the 2nd equiv. point Q is determined. The volume B of the aq. basic soln. required for the titration is determined. The rhodium concn. is calculated from the difference (B-A) in the volumes of the aq. basic soln. between the 2nd equiv. point and the 1st equiv. point. Since the 1st equiv. point and the 2nd equiv. point are determined, the rhodium concn. is easily and quantitatively determined with the general-purpose reagent and device with high accuracy.
