Title: Substrate for forming thin organic film
Inventor: ONISHI MICHIHIRO
IPC: C23C14/12
Filed: 1990-06-14
Abstract: PURPOSE:To improve flatness, chemical stability of surface, and peeling characteristic of thin organic film by using, as a substrate for forming a thin organic film, a stainless steel sheet which is subjected to thermal oxidation treatment after electropolishing. CONSTITUTION:Electropolishing is applied to a stainless steel sheet, such as SUS403. As an electrolyte, e.g., a phosphoric acid - sulfuric acid - chromic acid electrolyte, a sulfuric acid electrolyte, etc., are used. Moreover, it is desirable to previously smooth the surface by a mechanical polishing method, such as buffing, if necessary. After this electropolishing, thermal oxidation treatment is further performed, by which the impurities adhering to or adsorbed by the surface are removed by decomposition and also the thickness of a passivating film in the surface layer part is increased to improve chemical stability. The above-mentioned thermal oxidation treatment is performed is oxidizing atmosphere at 100-500 deg.C temp. range. Since the resulting substrate for forming a thin organic film has superior flatness and chemical stability of surface, a thin organic film having superior peeling characteristic and high quality can easily be formed.

Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To prevent semiconductor characteristics from deteriorating (for example, increase in a leakage current) by performing the dry etching of a nitride semiconductor with a reaction gas with gas containing a nitrogen element as an etching gas. SOLUTION: In a wafer used for manufacturing a device, an undoped GaN layer 2 and an Si-doped n+-AIGaN layer 3 are subjected to epitaxial growth on an SiC substrate 1. In this case, after mesa etching is made using a mixed gas of Cl2 and N2, electrodes 4 and 5 are formed. By increasing nitrogen partial pressure in dry etching, the generation of nitrogen void can be prevented. More specifically, by increasing the nitrogen partial pressure of a reaction gas on a nitride semiconductor etching surface by the reaction gas with gas containing a nitrogen element and suppressing the evaporation and departure of the nitrogen element that is the component of the nitride semiconductor from the etching surface, the generation of the nitrogen void can be prevented and further the deterioration of the characteristics of the device can be prevented.

Funther, the volume of the hydraulic pressure part on the wheel cylinder side is changed through a stroke and a plunger 12 is normally held at a top dead center through a crank mechanism. During antilock control, the plunger 12 is caused to effect a stroke by crank rotation through running of a motor to close a valve. By changing the volume of the hydraulic pressure part on the wheel cylinder side at a funther stroke after closing of the valve, a hydraulic pressure fed to the wheel cylinder is regulated.

Filed: 1979-11-30
Abstract: PURPOSE:To perform an optimum knocking control constantly in the ignition device with a knocking sensor by determing the upper and lower limit clamp voltags for a knocking control circuit and providing an ignition timing lagging signal based on the output from a knocking signal detecting means within a range between the determined upper and lower limits. CONSTITUTION:The knocking sensor NS detects electrically the vibration of an engine and provides a detection signal. The detection signal is fed into a high-pass filter HPF and band-pass filter BPF, by which the knocking frequency included in the detection signal is discriminated and outputted from a comparator CO1 as a knocking signal. When the knocking signal is outputted, an output terminal Vout of a knocking control circuit NC provides an output for lagging the ignition timing later than the ignition timing at that time. In the present invention, when the engine is started, the knocking control circuit NC outputs a minimum clamp voltage, and thereafter, over the whole driving range, the knocking control circuit NC outputs an appropriate clamp voltage in the range between the predetermined upper and lower limits corresponding to the output from the comparator CO1.
