IPC: H01L27/10
Filed: 1987-06-22
Abstract: PURPOSE:To raise a resistivity of a polycrystalline silicon film itself and obtain a high resistant element capable of miniaturization by diffusing oxygen in a polycrystalline silicon film and to further make the oxygen a donor in forming a high resistant element using the polycrystalline silicon film. CONSTITUTION:In forming a high resistant element using a polycrystalline silicon film, oxygen is diffused in the polycrystalline silicon film and the oxygen is made a donor. For instance, the polycrystalline silicon film having a film thickness of about 2000Angstrom  is formed on an insulating film of one main surface of a semiconductor substrate by CVD method. This film becomes a P-type conductivity film of about 10000OMEGAcm immediately after forming the film. Next, oxygen is diffused in the pollycrystalline silicon film by a thermal diffusion method in an oxidation atmosphere. Next, when heat treatment is performed at 450 deg.C in an inert atmosphere, a fixed rate of the oxygen diffused before is made the donor to compensate the P-type conductivity film for raising a resistivity of the polycrystalline silicon film. Then, as illustrated, the time of heat treatment at 450 deg.C is controlled so as to obtain a desired resistivity.

Title: Dry oil injecting method for oil immersed electric equipment
Inventor: HATANAKA SHIGEYUKI
IPC: H01F41/12
Filed: 1986-07-02
Abstract: PURPOSE:To dry electric equipment evenly in a short time and to suppress moisture absorption by immersing the equipment in insulating oil at above a predetermined temperature. CONSTITUTION:A transformer main body 4 is placed in a tank 1 of an oil immersed transformer. Lead wires of a winding 3 are taking out to bushings 5. A current is conducted through the winding 3 from a power source 14. When the temperature of the winding 3 becomes about 100 deg.C, insulating oil 7 at a temperature of about 50 deg.C, which undergoes deaeration and dehydration in an insulating oil storage tank 6, is injected in the tank 1. Then the equipment main body 4 is immersed. The water content in the equipment main body 4 is moved to the insulating oil 7 in a short time owing to the temperature difference between the equipment main body 4 and the insulating oil 7 and the difference in amounts of water contents. When the temperatures of the insulating oil 7 and the equipment main body 4 become approximately equal, the current conduction to the winding 3 is stopped. The insulating oil 7 in the tank is discharged to a dehydrating device 12 through an oil discharge valve 11. Then the new insulating oil, which undergoes dehydration and deaeration, is injected form the storage tank 6, and main body 2 is immersed. Since the oil can be injected immediatly after drying, moisture absorption after processing can be suppressed.

Abstract: PURPOSE:To improve mechanical durability and electromagnetic conversion characteristic by disposing a nonmagnetic low melting metal having <=65 deg.C m.p. by segregation and deposition to the circumferential surface of ferromagnetic acicular particles and enclosing the circumference of such acicular particles with a polymer. CONSTITUTION:The CoCr acicular particles 2 are formed on a substrate 1 perpendicularly to the plane of the substrate 1 and a deposited layer 3 of Bi is disposed around the acicular particles 2. A layer 4 of PE is packed between the acicular particles enclosed by Bi.

The stress to be exerted to the acicular particles by sliding with a magnetic head is relieved by the pressure of the PE layer 4, by which the mechanical durability and particularly sliding resistance of the recording layer are improved.
