Title: Magnet-type closed container
Inventor: SETO TAKESHI
IPC: B65D41/02
Filed: 1988-06-08
Abstract: PURPOSE:To improve a productivity and a volume-efficiency of a hermetically closed container and enhance a magnetic suction force of a magnet used therein, by employing a magnet of rare earth metal which is produced by coating a cast ingot with a ferromagnetic material, hot-machining the coated ingot at a particular temperature and then subjecting the machined product to heat-treatment. CONSTITUTION:A hermetically closed container is composed of a container body 2 containing a permanent magnet therein and a lid member which encloses ferromagnetic substance at a position aligned with that of the permanent magnet 1. A magnetic attraction force created between the permanent magnet 1 and the ferromagnetic substance serves to produce a hermetic seal between the container body 2 and the lid. The permanent magnet 1 is produced as follows. Rare earth metal such as yttrium and boron are weighed in a given procedure. The mixture is melted and cast to obtain a cast ingot which is then sheathed with pure iron. The sheathed ingot is subjected to hot-elongation at a temperature of 500 deg.C to 950 deg.C, where a machining rate is about 80%. The elongated product is heat-treated at a temperature of 250 deg.C to 1,000 deg.C for 24hr and cut and ground to produce the magnet fittable to the container body 2. Thus, the permanent magnet 1 suitable for the hermetically closed container and having a sufficient coercive force is obtainable only by subjecting to heat treatment.

Title: Operating method of furnace
Inventor: UIRIAMU JIYOZEFU SUNAIDAA
IPC: F23C5/00
Filed: 1995-05-17
Abstract: PURPOSE: To minimize the number of low NOx type burners required for attaining an arbitrary specified target NOx generation rate from a furnace by setting the NOx generation rate at a position remote from a flue higher than an equilibrium level and setting the NOx generation rate at a position close to the flue lower than the equilibrium level. CONSTITUTION: When a high NOx type burner is disposed in a furnace at a position remote from a flue 33, furnace gas generated through combustion stays longer in the furnace when it advances toward the flue 33. Consequently, the NOx level exceeding over the equilibrium level approaches gradually to the equilibrium level and thereby the NOx level decreases. When the burners 1-12 are replaced by low NOx type burners, NOx generation rate in the flue 33 is decreased extremely as compared with the case all burners 1-20 are operated as high NOx type burners. Thereby, the method can achieve higher NOx reduction rate than other methods.

Filed: 1983-08-02
Abstract: PURPOSE:To obtain the titled magnetic core which is excellent in DC superpositional characteristics by a method wherein a closed magnetic circuit magnetic core, having almost constant effective cross-sectional area at any part, is sluntly cut or ground, and the cross-sectional area is partially or continuously changed. CONSTITUTION:The closed magnetic circuit magnetic core, having almost constant effective cross-sectional area at any part, is sluntly cut or ground, and the cross-sectional area is partially or continuously changed so that it will be turned to prtially closed magnetic circuit. When a resin-impregnated amorphous magnetic core is used as a magnetic core, it has a high saturation magnetic flux density, excellent in DC superpositional characteristics, its iron loss is small when compared with silicon steel, and its frequency characteristics is excellent, thereby enabling to obtain desirable results. The magnetic core is usually manufactured by cutting or grinding the magnetic core sluntly. When it is used as a choke coil, a winding is performed partially or on the entire body. The DC superpositional characteristics can be changed arbitrarily by selecting the desired angle of cutting or grinding. Leakage magnetic flux can be reduced by making combination of magnetic cores. Also, DC superpositional characteristics can be changed arbitrarily by changing the thickness of spacers.

Abstract: PROBLEM TO BE SOLVED: To facilitate high withstand voltage design of guard ring system and make high temperature long time diffusion for forming a guard ring unnecessary, by deeply diffusing impurities in short time heat treatment, by filling semiconductor material in an annular trench formed on the main surface of a semiconductor substrate. SOLUTION: An annular trench 17 is formed around a transistor forming region 16 of an N-type epitaxial growth layer 13, by using reactive ion etching. In the state that the side wall of the annular trench 17 is maintained in a clean silicon surface, polycrystalline silicon 18 is deposited by a chemical vapor deposition method. After the polycrystalline silicon 18 except the annular trench 17 is eliminated, a transistor is formed. Thereby boron in the polycrystalline silicon 18 is diffused from the side surface and the bottom surface of the annular trench 17, in the course of heat treatment, and a P-type diffusion layer 30 is formed. The same effect as a guard ring is obtained by a PN junction formed in the N-type epitaxial growth layer 13.

Title: Prediction method of earthquake by radio waves
Inventor: HAYAKAWA MASASHI
IPC: H04B7/00
Filed: 1995-06-08
Abstract: PURPOSE: To contribute to reduction of damage due to earthquake by detecting the atmospheric plasma, generated as a sign of earthquake, using radio wave thereby predicting the earthquake with high reliability. CONSTITUTION: The chart indicates the variation in the phase of radio wave during 72 hours retroacting from the midnight of December 30, 1983 when an earthquake of M6.7 occurred in India. As compared with a chained line indicative of radio wave received without passing through the seismic center, a solid line indicative of a radio wave passed through the seismic center has crescent recesses 1a, 1b. Since the recesses are caused by an atmospheric plasma generated as a sign of earthquake, earthquake can be predicted by detecting such abnormalities in the received radio wave.
