Title: Production of metal member with through hole and metal member with through hole
Inventor: OMA HIDEYUKI
IPC: B21J5/06
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a production method of a metal member with a through hole of a small and long size capable of securing a precision for a formed position and straightness of the through hole well. SOLUTION: A through hole 21 is formed beforehand by drilling or backward extrusion and blanking for a metal stock having a low aspect ratio before forging. When an aspect ratio of the metal stock 20 is small, a forming precision of the through hole 21 is relatively easily secured. Reducing forging is conducted while inserting a mandrel 55 in the through hole 21. The stock 20, while being reduced in an axial cross section outer diameter and through hole inner diameter by a die hole 57 of a forging die 56, is formed to a non round shape in its outer shape corresponding to a die hole inner face. On the other hand, a through hole 21 inner face is restricted by the mandrel 55 and is formed so as to have a corresponding inner diameter. At this time, the mandrel 55 is pressed into a die hole 57 roughly in isotropy in the peripheral direction through the stock 20 not to cause deflection.  As a result, a forming precision of the through hole 2 finally formed for an obtained metal member 1 is improved.

Title: Magnetic steel sheet laminated core and its manufacture
Inventor: KAIDO TSUTOMU
IPC: H02K1/20
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To improve a thermal conductivity of a laminated core formed, by laminating magnetic steel sheets each coated with such a film that exhibits a bond ability when heated upon another, and bonding the steel sheets to each other, by heating by making the coefficient of thermal conductivity of the core in the laminating direction larger than a specific value of the coefficient of thermal conductivity in the steel sheets. SOLUTION: Magnetic steel sheets 31 used for a core 32 are coated with such films 33 that exhibit bond ability when heated. When the core 32 is formed by laminating the steel sheets 31 coated with the films 33 upon another and bonding the steel sheets 31 to each other by heating, the coefficient of thermal conductivity of the core 32 in the laminating direction is adjusted to >=1/5 of the coefficient of thermal conductivity in the steel sheets. A heat flow 35 between the laminated steel sheets (in the surface directions of the steel sheets) 35 also contributes to the thermal conductivity of the core 2 together with the intrasurface heat flow 34 of the steel sheets 31 bonded to each other with the films 33. Therefore, the temperature of the core 32 can be lowered by extracting heat from the heat flows 34 and 35.  In addition, the coefficient of thermal conductivity of the core 32 in the laminating direction is adjusted to >=2 times of that of a core formed by laminating magnetic steel sheets having no bonding ability in the laminating direction. Therefore, when the laminated core is integrated by bonding the steel sheets to each other, the coefficient of the thermal conductivity of the core in the laminating direction becomes higher and the heat-extractability of the core is improved.
