Title: Low-iron loss type oil-immersed transformer
Inventor: SUGA TOSHIROU
IPC: H01F27/12
Filed: 1981-11-28
Abstract: PURPOSE:To reduce the iron loss of an oil-immersed tranformer and to increase economical effect by a method wherein a cooling system for an iron core and that for coil are isolated and operation is performed by maintaining temperature on the iron core cooling system at a temperature higher than that on the coil  cooling system. CONSTITUTION:It is made clear that iron loss constantly generated in an iron core 2 decreases (about 0.1%/ deg.C) as temperature on the iron core 2 becomes higher. Therefore, if the cooling system for the iron core 2 is operated at higher temperature (about 100 deg.C which is allowable temperature for oil) than temperature at the cooling system for a coil 1 by isolating the cooling system for th iron core 2 and that for the coil 1 by a partition 5, iron loss can be decreased by about 5% and economical effect can be achieved because the iron core, itself, is originally high-heat resistant one enduring the annealing temperature close to 1,000 deg.C. As the secondary effect, exhaust heat temperature is high. Thus, a cooler can be miniaturized.

Title: Input protecting circuit
Inventor: OKADA YOSHIO
IPC: H01L27/02
Filed: 1985-09-03
Abstract: PURPOSE:To realize higher speeds and to improve voltage-withstanding capability by a method wherein an input protecting resistor is made to present resistance that is sufficiently lower at its end portion than at other portions. CONSTITUTION:The resistance to be presented by an input protecting resistor R is so caused as to be lower at its end portion A measured from its input side than at other portions. For example, the width is enlarged at the end portion A of the protecting resistor R, which results in a decrease in the resistance to be presented by the resistor R. The end portion A made larger than the other portions causes fusing if any to take place in the other portions. The voltage causing such a fusion represents the true voltage-withstanding capability of the input-protecting circuit. The portion A with its width enlarged presents less resistance, generates less heat, and radiates more heat, which all contributes to the attainment of higher speeds and improved voltage-withstanding capability.
