IPC: B29C45/76
Filed: 1989-03-15
Abstract: PURPOSE:To greatly shorten the set time of proper molding conditions and to facilitate the judgement of the quality of a molded item by a method wherein all the variables of the molding conditions in a molding cycle are measured and stored at every shot so as to abstract the measuring data of arbitrary molding conditions from stored measuring data in order to process the data for statistical analysis. CONSTITUTION:In case of extruder, the rotational speed and kneading speed of a kneader 37 are respectively detected and the temperatures of a die 41 and of a cooling water tank 43 are respectively detected so as to input these detection signals to a measurement signal inputting device 12. A desirable statistical analytical processing method, measuring items and timing signals are selected through a keyboard 19 and analyzed conditions such as number of shots, desirable time to analyze, which is determined by the elapsed time from the selected timing signals, and the like are inputted through the keyboard. Under the state just mentioned above, an arithmetic processing and control unit 14 abstracts the necessary analytical data from an auxiliary storage 18. After the statistical processing is performed from the measuring data, the analytical result is displayed on a CRT display 20.

Filed: 1987-03-19
Abstract: PURPOSE:To improve the smoothness on the surface of a forging product by hardening the surface of a work material after forging the same and finishing the work material in softened surface state after removing the oxidized film. CONSTITUTION:A work material is deformed in the necessary shape via the pressurizing stage 22 of a heating stage 20, closed die forging, etc., then, the working surface is once hardened at a hardening stage 24. The oxide film formed on the surface of the work material is then removed at a shot blasting stage 26, thereafter, the work material is pressurized by a nonoxidizing normalizing 28, cold sizing stage 30 to finish the surface thereof in a smooth state. Since the shot blasting is effected after hardening the material surface at the hardening stage 24 the retention of the indentation by the shot is prevented. Thus, the roughness on the surface of a forging product is improved to the extent of 10mum to improve the surface smoothness.

The cast material thus obtained undergoes a hot rolling in a hot wide-band rolling machine to set or produce a constant very homogeneous iron structure which depends on the temperature and the deformation with the grain size of 100 μm. The reshaping temperature during the hot rolling must be higher than 850 deg.C.  Thereafter, an explosive charge liner with a desired shape is formed from a hot rolled steel plate.

Title: Production of thin film
Inventor: FUJII KENICHI
IPC: H01L29/78
Filed: 1984-04-02
Abstract: PURPOSE:To reduce defects in a film by producing an amorphous silicon film and a silicon nitride film by means of a plasma CVD unit in which a magnet is disposed on the cathode side. CONSTITUTION:A thin film is produced with a plasma CVD unit in which a magnet 7 is disposed on the cathode side. As a result, electrons are subjected to Lorentz force which causes them to move spirally around the magnetic lines of force. Thus, in this unit, such phenomenon that the electrons impinge rapidly against a substrate 4 is inhibited more effectively as compared with a conventional unit in which no magnetic 7 is provided. Consequently, a thin film such as a thin film transistor with excellent element properties can be produced by this method.
