Title: Dry etching apparatus
Inventor: OKANO HARUO
IPC: C23F1/08
Filed: 1981-05-19
Abstract: PURPOSE: To increase the dry etching speed of the titled apparatus, by tapering off the upper surface outer peripheral section of a permanent magnet provided outside a magnetic field closed loop.  
     CONSTITUTION: A cathode 2 (a discharge electrode) of a non-magnetic material, or stainless steel, is opposed to a wall of a stainless decompression apparatus 1, and is connected via a matching circuit 3 with a high-frequency electric source 4. A magnetic means is provided in a non-contact state to the undersurface of the cathode 2, i.e. permanent magnets 10-aWe supported by iron pole piece 9 are arranged. The upper surface outer periphery section 37, that is, part of the magnetic means, of the permanent magnet outside the orthogonal magnetic field is tapered off. As a result, the electromagnetic field normal to the electric field at the section 37 becomes almost zero, the high-frequency electric power is predominantly consumed on the gap 15 to generate a lot of ions, and an arcuate magnetic line closed loop is formed over the surface of the cathode 2. The piece 9 is reciprocated by a motor 11 for a sample 12 on the cathode 2 to etch the desired whole surface of the sample 12.

Title: Fire extinguisher for transformer
Inventor: HOUKI YASUMICHI
IPC: A62C3/16
Filed: 1983-04-27
Abstract: PURPOSE:To prevent erroneous operation of a fire extinguisher when a transformer is not in trouble and increase the effect of fire extinguishing by jetting out non-combustible gas from a high-pressure cylinder only when both a stop valve and a heat detector operate. CONSTITUTION:When a heat detector and a stop valve 5 work simultaneously, an electro-magnetic valve 9 is operated and a valve 8 opens, and the oil in a pipe 11 and diaphragm 10 flows into a tank 7 at once by a specified volume. The diaphragm 10 contracts with its rod 12 by the reduction of the pressure in the diaphragm 10. The rod 12 thereby moves in the same direction as the diaphragm and a mechanism 12a that is associated with the rod 12 operates. Accordingly, the high-pressure gas from a high-pressure cylinder 13 jets out and its pressure is reduced to a specified pressure when the high-pressure gas passes through an expansion chamber 15, and the gas advances from a pipe 14 to a transformer 1 and rises through it as foam. The oil in the transformer 1 is stirred with the cold oil at the bottom moving upwards, which can keep the oil temperature at the oil level below the catch fire point and fire extinguishing is possible.

Title: Television receiver
Inventor: IRIE SHOICHI
IPC: H04N5/00
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent electric shock caused by static electricity even when a metallic outside case body is touched by consuming electrostatic energy by driving the oscillation of IC. SOLUTION: The electric energy charged on an outside case cabinet by static electricity is consumed by oscillation circuits 11 and 12 mainly based on the IC of C-MOS. In the case of circuit 11 for positive charge, its side connected to the outside case cabinet becomes the plus side of power source and its ground becomes G. When a human body is considered as a power source, the metallic cabinet in contact with the human body becomes a plus side power source, and G connects the minus side through the human body in contact with the ground. The output of gate is oscillated by feeding it back to an input by providing timewise delay through multistage connection. Since circuits are respectively independently constituted for positive charge and negative charge, charging can be removed in spite of polarity on the human body.
