IPC: G11B5/851
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To integrally form a magnetic recording layer and a yoke layer, and to improve magnetic efficiency. SOLUTION: A film of alloy of rare-earth metals and iron is formed in an early stage in an atmosphere of gas containing inert gas and nitrogen and/or carbon, or in atmosphere of only an inert gas. A film of alloy of rare-earth metals and iron is formed in sequence by increasing the density of the gas containing nitrogen and/or carbon. In this way, the density of nitrogen and/or carbon of the upper layer of the film is larger than that of the lower layer. The lower layer is formed to be a soft magnetic layer. A hard magnetic layer is formed on the lower layer and is integral with the same. A boundary part 5 is formed between the two layers in such a way that the composition of one of the layers gradually decreases toward the other layer. The lower layer is formed as yoke layer 3 and the upper layer is formed as magnetic recording layer 4 to manufacture a magnetic recording medium.

Title: Electric rice cooker
Inventor: IKEDA NORIO
IPC: A47J27/00
Filed: 1990-02-16
Abstract: PURPOSE:To obtain a rice cooker in which the irregular temperature distribution in ingredient is diminished during cooking and uneven cooking is avoided, by a method wherein a cast-in heater has two sheathed heaters around the circumference and in the middle, and the sheathed heaters are independently energized. CONSTITUTION:When ingredient 17 reaches a specified temperature, a temperature detector attached on the bottom of an inner pot 15 detects the temperature and sends the detected signal to a controller 18. As a result, the controller 18 begins to alternately supply power to an outer sheathed heater 13a and an inner sheathed heater 13b. When the outer sheathed heater 13a is energized, the vicinity of the circumference of the inner pot 15 is mainly heated, and when the inner heater 13b is energized, the central part of the pot is mainly heated, so that convection currents shown by arrows (a) and (b) are developed repeatedly. Therefore, a foaming current, which continuously pushes up the rice in the pot 15 locally, is not developed, so that the surface of the boiled rice is not made uneven after cooking is finished, and boiled rice without irregular cooking can be obtained.

The separated boards 5 are transferred to an assembly line. In each of assembly processes, the symbol mark 4 of the board which is judged defective in a check process executed after an assembly process is erased. For instance, as shown in 8 figure A, the board 1 is separated into the boards 5, the electric conduction of the conductive path 2 is checked, resin a is applied onto the symbol mark 4 of the board 5 judged defective to prevent the mark 4 from being recognized in a following process. The same procedure is executed in a following process B. Therefore, in a die bonding process shown in a figure C, only the board 5 whose symbol mark is recognized is die-bonded.
