Title: Manufacture of die having high strength and high toughness by warm hobbing
Inventor: YOSHIDA HIROAKI
IPC: C21D8/00
Filed: 1995-05-01
Abstract: PURPOSE: To manufacture a die having high strength and high toughness by the warm hobbing. CONSTITUTION: After the general tool steel including the hot die steel and the high speed steel is once heated at >=850 deg.C, the temperature is dropped, the forging is achieved (hobbing) at the temperature between 300 deg.C and 800 deg.C, and then cooled to the room temperature at appropriate speed, and only the tempering is achieved by dispensing with the subsequent hardening treatments. Further improved effect to the service life of the die can be demonstrated by adding the finish electrical discharge machining after the tempering. The die having high strength and high toughness can be manufactured. Because the initial hardness of the die in the practical use can be greatly increased thereby, the service life of the die can be remarkably increased.

Title: Resin mold-type transformer and formation method
Inventor: KUBOTA MASAHIRO
IPC: H01F30/00
Filed: 1993-05-21
Abstract: PURPOSE:To protect a core from a crack caused by a change in ambient temperature and reduce a change in self-inductance as electro-magnetic characteristics, by fixing spaces among coils and between the core and coils except for some part of them. CONSTITUTION:There are spaces (G) between coils 2a and 2b and between cores 1a and 1b and the coils 2a and 2b. Even when a change in ambient temperature causes displacement 4 as indicated by an arrow in the coils 2a and 2b, the displacement 4 is absorbed by the space (G) and doesn't affect the cores 1a and 1b. Consequently, the core can be protected from a crack caused by a change in ambient temperature, and at the same time a change in self- inductance can be reduced.

Filed: 1981-09-09
Abstract: PURPOSE:To improve the efficiency during the operation and improve starting acceleration characteristics, by applying ultrasonic vibrations from the outer periphery of a rotor resulting in the release of the contact between an Al condutor and an iron core, after casting an Al conductor into the rotor groove. CONSTITUTION:After assembling a rotor core in the process 1, the Al conductor is cast into the rotor groove in the process 3.
