Title: Formation of silicon oxide film
Inventor: INOUE YUSHI
IPC: H01L21/768
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a silicon oxide film, by transforming a hydrogen resin film into a ceramic-like silicon oxide film, which can prevent formation of fine projections on the silicon oxide film. SOLUTION: A hydrogen silsesquioxan resin film is formed on a substrate 30 by a spin coating process and then subjected to an annealing process in an N2 atmosphere to form a pre-ceramic-like silicon oxide film 40. The film 40 is next subjected to an annealing process in an atmosphere containing O2 and N2 gases in a temperature range of not smaller than 250 deg.C and less than 400 deg.C to be transformed into a ceramic-like silicon oxide film. The performance of the annealing process for the ceramic formation at temperatures less than 400 deg.C enables prevention of formation of fine projections on the film 40. The film 40 may be transformed to the substance housing ceramics property without using the pre-ceramic formation process.

Abstract: PURPOSE:To enhance the abrasion resistance of the root part on the side of the kneading part of the spiral blade of a feed part by forming a flame spraying layer of an abrasion-resistant material to the root part on the side of the kneading part of the spiral blade and forming a hard chromium plating layer to the whole of the outer peripheral surfaces of the feed part containing the flame spraying layer and the kneading part. CONSTITUTION:A rotor for a kneader is prepared from chromium molybdenum steel susceptible to hardening heat treatment and subjected to hardening heat treatment. A flame splaying layer 11 of an abrasion-resistant material is formed to the root parts 5A, 5B of the blade surfaces in the before and behind direction of each spiral blade 5 and the curved surface of the start part 7 of the feed blade 7 easiest to abrade of a kneading blade. Further, a hard chromium plating layer 12 is formed to the whole of the outer peripheries of the feed part 6 containing the flame spraying layer 11 and the kneading blade as shown by the two-dotted broken line in a drawing. Since the flame spraying layer composed of the abrasion-resistant material is formed under the hard chromium plating layer at the root part on the side of the kneading part of the spiral blade, a matrix material is protected by the flame spraying layer even when the plating layer is thin and the local and selective abrasion of this part can be effectively prevented.

Title: Variable bias circuit
Inventor: SAKURABA NOBUTOSHI
IPC: H04N5/14
Filed: 1978-09-28
Abstract: PURPOSE: To stabilize bias control even through remote operation by using a simple current control element.  
     CONSTITUTION: One terminal of resistance 3 is connected to a reference power supply held at the earth potential through seires-connected transistor 4 and resistance 5 so as to control the main current through transistor 4 by variable voltage supply 6. In the above-mentioned constitution, setting the base potential of transistor 4 corresponding to a desired bias potential results in that the collector-emitter main current corresponds to the base potential. Further, this main current causes voltage drops across resistances 2, 3 and 5 respectively and the base potential of the transistor can therefore be brought under the variable control of the potential at the output terminal. In this case, the base input impedance of transistor 4 is hardly set high, so that a connected smoothing capacitor of small capacity can easily prevent a bad influence of a noise, etc., upon an output signal.
