Title: Ion-etching method
Inventor: OKANO HARUO
IPC: C23F1/00
Filed: 1978-11-01
Abstract: PURPOSE: To conduct etching at an excellent selectivity, by generating electric field and magnetic field, which cross each other, along an annular slit formed by a cathode and a permanent magnet to form plasma, and by irradiating the ions on the material to be etched.  
     CONSTITUTION: The apparatus body is evacuated to a vacuum, and a high voltage of 1,000V is applied across an anode terminal 62 and a vessel 55 to form loop- shaped cross electromagnetic field along the annular slit 59 made in an upper lid 57a for a permanent magnet 58 and box-shaped cathode 57 made of mild steel. C 2 F 6  gas is introduced through a gas inlet 63 and is made collide with space charges which revolve in the cross electric field to form plasma. The positive ions in the plasma are released through an ion outlet 60 to form an ion beam. Then a shutter 53 is opened, and the SiO 2  layer formed on the surface of a polycrystal Si placed on the surface of the sample stand 54 is etched selectively by the ion beam. This method gives an etching speed larger than that of the conventional method using hot cathode type ion source.

Filed: 1989-05-26
Abstract: PURPOSE:To improve the reliability of the diagnostic display by performing a setting operation to a cursor control part via a main control part in an internal diagnostic state of a display device and carrying out the display of the cursor to show a diagnostic state. CONSTITUTION:A main control part 12 sets the cursor display states set previously in response to the diagnostic states to a cursor control part 23.

IPC: H01F37/00
Filed: 1985-06-20
Abstract: PURPOSE:To inhibit the temperature rise of a ballast largely while reducing noises by inserting a section between a coil and a case for a ballast proper with a thermal conductive rubber so as to be fast stuck. CONSTITUTION:A thermal condductive rubber 11 is installed fast stuck between a coil 3 and a case 5 in a ballast for a discharge lamp.

Filed: 1983-07-25
Abstract: PURPOSE:To form two beam radiation patterns different in the specifications at a high accuracy with a set of antenna train by combining two input signals distributed according to the ratio of different radiation patterns to be fed to an antenna element. CONSTITUTION:Input signals A and B are distributed with distributors 21 and 21' at the ratio necessary for forming a specified radiation pattern.
