Title: Manufacture of iron core
Inventor: YAMADA KAZUO
IPC: H01F41/02
Filed: 1984-03-01
Abstract: PURPOSE:To contrive improving magnetic characteristics raising the temperature of an iron core with a uniform temperature distribution and to enable annealing without damaging the coil of a transformer wound around an iron core by annealing with the heat generated from the iron core itself due to power loss of exciting the iron core. CONSTITUTION:If an iron core 11 is excited by an AC current in a tentatively wound coil 14 from a high frequency AC power source 16, an eddy current flows in the iron core 11 and Joule heat is generated by the power loss to raise the temperature of the iron core 11. When the temperature is raised to the suitable annealing temperature of an amorphous magnetic alloy plate 12, the suitable temperature and time are maintained constant by adjusting the voltage. As soon as the AC current to the tentatively wound oil 14 is cut off and the iron core 11 is started to be cooled, a DC current is supplied to the tentatively wound coil 14 from a DC power source 18, magnetic field is formed for the iron core 11 and the iron core 11 is cooled in the magnetic field. After annealing, the tentatively wound coil 14 is removed from the iron core 11.

Patent JP-H01214165-A (JP)
Title: Semiconductor device
Inventor: SUGA JIRO
IPC: H01L21/331
Filed: 1988-02-23
Abstract: PURPOSE:To make distances between respective base electrode and emitter regions uniform and improve high frequency characteristics, by making a base contact or an electrode circular and the junction periphery of each emitter region concentric. CONSTITUTION:A circular emitter region is provided by surrounding a base contact or an electrode 2 in each base region 1. In this surface disposition, as most of currents concentrate at the periphery of each emitter, a ratio F of each emitter periphery length LE to each collector area AC, that is, F=LE/AC increases so as to treat a large electric current by improving area efficiency. This approach allows each base electrode 1 to be circular and to be disposed them into a form of equilateral triangle and further the periphery of each emit ter to be circular. In the case where sizes of each part are x, b, and c as shown by Fig., if the relation among them is expressed by an expression: x=b=c, its figure of performance becomes a little smaller than that of rectangle disposi tion but becomes larger than those of comb like or overlay shaped cases. Thus, distances between respective base electrode and emitter regions become uniform and high frequency characteristics are improved.

Abstract: PURPOSE:To reduce quantity of electricity for formation and to shorten formation time by preparing paste by kneading with water the material which is prepared by mixing a mixture consisting of minium and sulfuric acid with lead powder for shortening-kneading time. CONSTITUTION:Fine particles containing PbO2 are prepared by feeding respective fixed quantities from a minium storage tank 1 and a sulfuric acid storage tank 2 to a mixer 5 through quantitative feed devices 3 and 4 to be mixed with each other by means of a stirring blade 6. Water content in fine particles evaporates during stirring, because of rising of a temperature of fine particles due to heat of reaction of minium with sulfuric acid during stirring and mixing. Prepared fine particles containing PbO2 are mixed with lead powder by using a continuous quantitative mixing device 8 for being stored in a storage tank 9. Fixed quantity of the mixed fine particles are fed to a paste kneading device 12 through a quantitative feed machine 11 and kneaded with water from a water storage tank 13 to be filled with a paste filling machine 15. By this step, lead compound fine particles prepared from minium and lead powder are mixed in advance and dispersed uniformly by means of a dry mixing way of comparatively easy dispersion, resulting in finishing of kneading in short time thereafter.

Filed: 1996-02-02
Abstract: PURPOSE: To dispense with providing an insensing-level region in a floating gate voltage Vfg to make the amount of a stored charge of a floating gate disperse in a narrow range even if an insensing-level region is provided in a drain current Ids for preventing an erroneous readout from being generated in an EEPROM, which conducts a multi-valued storage utilizing the corresponding relation between the floating gate voltage Vfg and the drain current Ids.
